Description:
LAUNDRY DETERGENT AND/OR FABRIC CARE COMPOSITIONS COMPRISING A CHEMICAL ENTITY, WHICH CONTAINS A DEPOSITION AID, AND A POLYMER Field of the Invention The present invention relates to laundry detergent and/or fabric care compositions comprising a chemical entity and a polymer ; wherein the chemical entity comprises a deposition aid having a high affinity for cellulose and a benefit agent.

Background of the invention Modern laundry detergent and/or fabric care compositions contain various detergent ingredients having one or more purposes in obtaining fabrics which are not only clean, fresh and sanitised but also have retained appearance and integrity. Therefore, benefit agents such as perfumes, hygiene agents, insect control agents, bleaching agents, fabric softeners, dye fixatives, soil release agents, and fabric brightening agents have been incorporated into laundry detergent and/or fabric care compositions. In using such detergent components, it is important that these compounds deposit on the fabrics so as to be effective during or after the laundering and/or fabric care process.

Polymers have been used by the detergent industry for some years. Indeed, it is known that polymers provide a variety of benefits to detergent compositions such as fabric cleaning, anti-redeposition of soils, color care, whiteness maintenance, and/or fabric softness.

However, there still remains a need to formula laundry detergent and/or fabric care compositions providing improved cleaning and fabric care properties.

The above objective has been met by formulating laundry detergent and/or fabric care compositions comprising a chemical entity and a polymer ; wherein the chemical entity comprises a deposition aid having a high affinity for cellulose and a benefit agent.

W097/01629 describes cellulolytic enzyme preparation wherein the mobility of the cellulase component may be reduced by adsorption to an insoluble or soluble carrier e. g. via the existing or newly introduced CBD. W097/28243 describes a process for removal or bleaching or soiling or stains from cellulosic fabrics wherein the fabric is contacted in aqueous medium with a modified enzyme which comprises a catalytically active amino acid sequence of a non-cellulolytic enzyme selected from amylases, proteases, lipases, pectinases and oxidoreductases, linked to an amino acid sequence comprising a cellulose binding domain and a detergent composition comprising such modified enzyme and a surfactant. W098/00500 discloses a composition comprising a protein

deposition aid having a high affinity for fibers or a surface and having a benefit agent attached/adsorbed thereto.

US 5, 789, 369 discloses laundry detergent compositions comprising modified polyacrylic acid polymers having anti-redeposition performance. WO 97/42288 describes laundry detergent compositions comprising detersive surfactant, non- cotton fabric soil release polymer, water-soluble/dispersible modified polyamine cotton soil release agent and carrier and adjunct ingredients. US 5, 804, 543 discloses laundry detergent compositions comprising anionic and nonionic surfactants, detergent builder, and a dye transfer inhibiting polymer. These compositions provide soil and stain removal as well as dye transfer inhibition benefits. WO 98/29529 discloses laundry detergent compositions comprising detersive surfactants, organic/inorganic detergency builder and a dye fixative ; providing appearance benefits and anti-fading to fabrics and textiles. WO 95/27028 discloses detergent compositions giving good fabric whiteness, comprising zeolite MAP, specified whitener, polymer and/or oxidative catalyst.

However, none of these documents disclose a laundry detergent and/or fabric care composition comprising a chemical entity and a polymer ; wherein the chemical entity comprises a deposition aid having a high affinity for cellulose and a benefit agent ; for improved cleaning and fabric care performance.

Summary of the invention The present invention relates to laundry detergent and/or fabric care compositions comprising a chemical entity and a polymer ; wherein the chemical entity comprises a deposition aid having a high affinity for cellulose and a benefit agent. These compositions provide improved fabric cleaning including stain/soil removal, anti-redeposition of soils and/or whiteness maintenance and improved

fabric care including color care, fabric softness, anti-wrinkling, anti-bobbling and anti-shrinkage properties to fabrics.

Detailed description of the invention The present invention relates to laundry detergent and/or fabric care compositions comprising a chemical entity and a polymer ; wherein the chemical entity comprises a deposition aid with a high affinity for cellulose and a benefit agent.

It has now surprisingly been found that the laundry detergent and/or fabric care compositions of the present invention combining a chemical entity comprising a deposition aid with a high affinity for cellulose and a benefit agent, with a polymer provide improved fabric cleaning including stain/soil removal, anti-redeposition of soils and/or whiteness maintenance and improved fabric care including color care, fabric softness and/or anti-wrinkling, anti-bobbling and anti-shrinkage properties to fabrics. Without wishing to be bound by theory, it is believed that the binding of the deposition aid of the chemical entity onto the fabric results in a disruption of the fabric fibers. Therefore, the disruption of the fabric surface leaves the fibers more accessible to polymer activity, and thus results in enhanced performance of polymer properties. Moreover, the increased fabric fiber accessibility enhances the benefits obtained from the benefit agents of the chemical entity.

Suitable polymers for the purpose of the present invention include soil release polymers, dispersants, and anti-redeposition polymers. These polymer types provide fabric cleaning including stain/soil removal, anti-redeposition of soils and/or whiteness maintenance. Also suitable polymers are dye transfer inhibitors providing fabric color care and whiteness maintenance ; and flocculants providing improved fabric care including color care and/or fabric softness.

THE CHEMICAL ENTITY

The laundry detergent and/or fabric care compositions of the present invention comprise as an essential element, a chemical entity. Such chemical entities comprise one or more deposition aid (s) having a high affinity for cellulose and one or more benefit agent (s), and potentially one or more linking region (s).

The chemical entities of the present invention are comprised in the laundry detergent and/or fabric care compositions at a level of from 0. 00001% to 50%, preferably from 0. 001% to 20%, more preferably from 0. 1% to 10% by weight of the total composition.

The Deposition Aid The deposition aid according to the present invention is any material which has a high affinity for cellulose. Suitable deposition aids for the present invention are enzymes. The preferred enzymes are cellulases, lipases, phospholipases, proteases, cutinases, keratinases, keratanases, peroxidases, gluco-amylases, amylases, xylanases, esterases, acetylesterases, pectinases, reductases, oxidases, phenoloxidases, lipoxygenases, ligninases, pullulanases, tannases, pentosanases, chitinases, mannanases, ß-glucanases, arabinosidases, arabinofuranosidases, hyaluronidase, chondroitinase, dextranase, transferase, glycosyltransferases, laccase, or carbohydrases. Cellulases are especially preferred.

Preferably, the deposition aid for the purpose of the present invention is a binding domain of one of the aforementioned enzymes. In the context of the present invention the binding domain represents the binding site of an enzyme, defined as a sequence of amino acids which conserves the binding affinity of the binding site. It is preferred that the binding site represented by the deposition aid is that of the enzymes cellulase, lipase, cutinase, keratinase, or protease. Especially preferred is the binding site of cellulase, in particular the Cellulose Binding Domain (CBD).

For the purposes of the present invention, the especially preferred deposition aid is indeed an"amino acid sequence comprising a Cellulose Binding Domain

(CBD)", a term which is intended to indicate an amino acid sequence capable of effective binding of the cellulase to a cellulosic substrate (e. g., as described in P.

Kraulis et al., Determination of the three-dimensional structure of the C terminal domain of cellobiohydrolase I from Trichoderma reesei. A study using nuclear magnetic resonance and hybrid distance geometry-dynamically simulated annealing. Biochemistry 28 : 7241-7257, 1989). The classification and properties of cellulose binding domains are presented in P. Tomme et al., in the symposium "Enzymatic degradation of insoluble polysaccharides" (ACS Symposium Series 618, edited by J. N. Saddler and M. H. Penner, ACS, 1995).

Cellulose-binding (and other carbohydrate-binding) domains are polypeptide amino acid sequences which occur as integral parts of large polypeptides or proteins consisting of two or more polypeptide amino acid sequence regions, especially in hydrolytic enzymes (hydrolases) which typically comprise a catalytic domain containing the active site for substrate hydrolysis and a carbohydrate- binding domain for binding to the carbohydrate substrate in question. Such enzymes can comprise more than one catalytic domain and one, two or three carbohydrate-binding domains, and they may further comprise one or more polypeptide amino acid sequence regions linking the carbohydrate-binding domain (s) with the catalytic domain (s), a region of the latter type usually being denoted a"linker"or"linking region".

Examples of hydrolytic enzymes comprising a cellulose-binding domain are cellulase, xylanases, mannanases, arabinofuranosidases, acetylesterases and chitinases."Cellulose-binding domains"have also been found in algae, e. g. in the red alga porphyra purpura in the form of a non-hydrolytic polysaccharide- binding protein [see P. Tomme et al., Cellulose-binding domains-Classification and Properties in Enzymatic Degradation of Insoluble Carbohydrates, John N.

Saddler and Michael H. Penner (Eds.), ACS Symposium Series, No. 618 (1996)].

However, most of the known CBDs (which are classified and referred to by P.

Tomme et al. (op. cit.) as"cellulose-binding domains") are derived from cellulases and xylanases.

In the present context, the term"cellulose-binding domain"is intended to be understood in the same manner as in the latter reference (P. Tomme et al., op. cit.) The P. Tomme et al. reference classifies more than 120"cellulose-binding

domains"into 10 families (I-X) which may have different functions or roles in connection with the mechanism of substrate binding. However, it is to be anticipated that new family representatives and additional families will appear in the future.

In proteins/polypeptides in which CBDs occur (e. g. enzymes, typically hydrolytic enzymes such as cellulases), a CBD may be located at the N or C terminus or at an internal position.

The part of a polypeptide or protein (e. g. hydrolytic enzyme) which constitutes a CBD per se typically consists of more than about 30 and less than about 250 amino acid residues. For example, those CBDs listed and classified in Family I in accordance with P. Tomme et al. (op. cit.) consist of 33-37 amino acid residues, those listed and classified in Family Ila consist of 95-108 amino acid residues, those listed and classified in Family VI consist of 85-92 amino acid residues, whilst one CBD (derived from a cellulase from Clostridium thermocellum) listed and classified in Family VII consists of 240 amino acid residues. Accordingly, the molecular weight of an amino acid sequence constituting a CBD per se will typically be in the range of from about 4kD to about 40kD, and usually below about 35kD.

Cellulose binding domains can be produced by recombinant techniques as described in H. Stafbrand et al., Applied and Environmental Microbiology, Mar.

1995, pp. 1090-1097 ; E. Brun et al., (1995) Eur. J. Biochem. 231, pp. 142-148 ; J. B. Coutinho et al., (1992) Molecular Microbiology 6 (9), pp. 1243-1252 In order to isolate a cellulose binding domain of, e. g. a cellulase, several genetic engineering approaches may be used. One method uses restriction enzyme to remove a portion of the gene and then to fuse the remaining gene-vector fragment in frame to obtain a mutated gene that encodes a protein truncated for a particular gene fragment. Another method involves the use of exonucleases such as Ba131 to systematically delete nucleotides either externally from the 5' and the 3'ends of the DNA or internally from a restricted gap within the gene.

These gene-deletion methods result in a mutated gene encoding a shortened gene molecule whose expression product may then be evaluated for substrate- binding (e. g. cellulose-binding) ability. Appropriate substrates for evaluating the

binding ability include cellulosic materials such as Avicel and cotton fibres. Other methods include the use of a selective or specific protease capable of cleaving a CBD, e. g. a terminal CBD, from the remainder of the polypeptide chain of the protein in question.

Preferred CBDs for the chemical entities of the present invention are selected from the group consisting of : CBDs CBHII from Trichoderma reesei, CBDs CenC, CenA and Cex from Cellulomonas fimi, CBD CBHI from Trichoderma reesei, CBD Cellulozome from Clostridium cellulovorans, CBD E3 from Thermonospora fusca, CBD-dimer from Clostridium stecorarium (NCIMB11754) XynA, CBD from Bacillus agaradherens (NCIMB40482), and/or CBD family 45 originating from the fungal Humicola Insolens cellulase sold under the tradename "Carezyme"by Novo Nordisk A/S. Carezyme is an endoglucanase from family 45, derived from Humicola insolens DSM1800, having a molecular weight of about 43kDa and exhibiting cellulolytic activity.

More preferred CBDs for the chemical entities of the present invention are the CBD CenC from Cellulomonas fimi, CBD Cellulozome from Clostridium cellulovorans, CBD family 45 from Humicola Insolens, and/or mixtures thereof.

The linking region The improved chemical entities of the present invention may further comprise one or more linking region (s). The term"linking region"is intended to indicate a region that adjoins the deposition aid and connects it to the chemical component (s). Suitable linking regions, if encompassed in the improved chemical entity of the present invention, are characterized by having one or more attachment point (s) for a chemical component and one or more moiety that will covalently bind to the deposition aid. Preferably, the linking regions of the present invention will encompass at least one attachment point to the deposition aid and more than one reactive group available to attach a chemical component, hereinafter referred to as a"polyreactive linking region".

The linking will preferably be achieved on the Tyrosine, Cysteine or Lysine. Especially, the free NH2 group from a Lysine amino acid or of the terminal amino acid within the peptidic polymer is used as attachment points for chemicals containing aldehyde, ene one, ketone, or acid or halogene moeities Also suitable compound are the amino acid derivatives selected from tyrosine ethylate, glycine methylate, tryptophane ethylate and mixture thereof, These peptidic polymers can be attached to the amino acid sequence comprising a cellulose binding domain, by recombinant technology. An example of the recombinant technique describing the expression of an enzyme with the CBD of different origin is described in S. Karita et al., (1996) Journal of Fermentation and Bioengineering, Vol. 81, No. 6, pp. 553-556. The polyreactive linking region can comprise from 1 to about 100 amino acid residues, in particular of from 2 to 40 amino acid residues, e. g. from 2 to 15 amino acid residues. It is preferred to use amino acids which are less favoured by the surrounding proteases. Indeed, any combination of amino acids can be selected to achieve maximal weight efficiency and protease stability. Suitable amino acid linking regions are the Humicola insolens family 45 cellulase linker, the NifA gene of Klebsiella pneumoniae-CiP linker, the E. coli OmpA gene-CiP linker, the E3 cellulase Thermomonospora fusca linker and the CenA cellulase linker ; preferably the

Humicola insolens family 45 cellulase linker and the E3 cellulase Thermomonospora fusca linker.

Depending on the intended activity of the attached chemical component, said chemical components can be linked permanently or temporarily to the deposition aid and/or linking region. Therefore, the present invention further encompasses chemical entities wherein the chemical component is linked to the deposition aid and/or linking region by a weak bond. Said weak bond is a bond which can be enzymatically cleaved, oxidized, cleaved by light radiation and/or hydrolyse during or after the wash/fabric care process in order to release the chemical component (s). Examples of weak bonds are Shiff-base or beta-amino-ketone bonds.

The Benefit Agents The chemical entity of the present invention comprises a benefit agent. The benefit agent is understood within the context of the present invention as any compound which gives a desirable effect on a fibre or fabric. The benefit agents encompassed in the chemical entity are preferably selected from perfumes, hygiene agents, insect control agents, fabric softening agents, soil release agents, bleaching agents, dye fixatives agents, brighteners, surfactants and/or mixtures thereof. More preferred benefit agents are the perfume agents, insect control agents, hygiene agents and/or bleaching agents.

In addition to these chemical entities, the compositions of the present invention can comprise the same benefit agents unmodified.

The benefit agent of the present invention may be encapsulated. Suitable encapsulating material includes starches, poly (vinylacetate), urea/formaldehyde condensate based materials. Especially suitable encapsulating materials are water soluble capsules which consist of a matrix of polysaccharide and polyhydroxy compounds such as described in GB 1, 464, 616. Other suitable water soluble encapsulating materials comprise dextrins derived from ungelatinized starch acid-esters of substituted dicarboxylic acids such as described in US 3, 455, 838. These acid-ester dextrins are, preferably, prepared

from such starches as waxy maize, waxy sorghum, sago, tapioca and potato. Suitable examples of said encapsulating materials include N-Lok manufactured by National Starch. The N-Lok encapsulating material consists of a modified maize starch and glucose. The starch is modified by adding monofunctional substituted groups such as octenyl succinic acid anhydride.

Perfumes A chemical entity suitable for the laundry detergent and/or fabric care compositions of the present invention is a perfume entity wherein at least one benefit agent is a perfume compound linked to a deposition aid and/or linking region via a weak bond. It is believed that high substantivity of the perfume will be achieved by linking the perfume agents to a deposition aid.

Without wishing to be bound by theory, it is believed that the slow hydrolysis of the weak bond within the improved perfume entity will improve the release of the perfume. Indeed, after the wash or fabric care process, the weak bond will be hydrolyse and the perfume will be released. It has been surprisingly found that these perfume entities in the compositions of the present invention, provide increased leasing and long-lasting fragrance through economic and effective means. Furthermore, without wishing to be bound by theory, it is believed that the binding of the perfume entities of the present invention to the fabric surface results in the disruption of the fabric fibers. The laundry soils and stains are so loosened from the fabric fibers and become more accessible to polymer cleaning.

Moreover, the fabric surface disruption leaves the fibers accessible, enhancing polymer activity thereon. Therefore, it has been found that the laundry detergent and/or fabric care compositions of the present invention combining these perfume entities with a polymer, provide long-lasting fragrance on dry laundred fabric as well as improved fabric cleaning and/or anti-redeposition of soils and/or augmented color care and/or whiteness maintenance and/or enhanced fabric softness.

Fully-formulated fragrance can be prepared using numerous known odorant ingredients of natural or synthetic origin. The range of the natural raw substances can embrace not only readily-volatile, but also moderately-volatile and slightly-volatile components and that of the synthetics can include

representatives from practically all classes of fragrant substances, as will be evident from the following illustrative compilation. In this list of perfume ingredients, some are commercial names conventionally known to one skilled in the art, and also includes isomers. Such isomers are also suitable for use in the present invention. A typical disclosure of suitable ketone and/or aldehydes, traditionally used in perfumery, can be found in"perfume and Flavor Chemicals", Vol. I and 11, S.

When encompassed in the compositions of the present invention, these perfume entities will be generally comprised at a level of from 0. 001% to 20%, preferably from 0. 005% to 5% by weight of the total composition.

Hygiene agent A further suitable chemical entity for the laundry detergent and/or fabric care compositions of the present invention is a hygiene entity wherein at least one benefit agent is a hygiene agent, linked to a deposition aid. The hygiene agent will be linked to the deposition aid via weak bond in order to release the active material upon time during or after the wash or fabric care process. Preferably, the hygiene agent comprises an hydroxyl, carboxyl or aldehyde reactive moiety.

It has been surprisingly found that such hygiene entities in the laundry detergent and/or fabric care compositions of the present invention, provide an extremely long lasting and very efficient control of the micro-organism growth on stored and weared fabrics. Furthermore, without wishing to be bound by theory, it is believed that the hygiene entity interacts with the fabric surface in such a way as to increase the accessibility of soils, stains, and fabric fibers. Therefore, it has been found that the laundry detergent and/or fabric care compositions of the present invention combining these hygiene entities with a polymer provide excellent control of micro-organism growth on stored and weared fabrics, as well as improved polymer performance such as fabric cleaning and/or anti- redeposition of soils and/or augmented color care and/or whiteness maintenance and/or enhanced fabric softness.

Sanitisation includes all positive effects obtained by the inhibition or reduction of microbial activity on fabrics and other surfaces, such as the prevention of malodour development and bacterial/fungal growth. For example, it provides prevention of malodour development on stored and weared fabrics. In particular, the composition of the invention will inhibit or at least reduce the bacterial and/or fungal development on moist fabric waiting for further laundry processing and thereby preventing the formation of malodour. The term hygiene agents herein encompasses fungicides and antimicrobials that when applied to fabric respectively prevent or reduce the growth of fungi or bacteria. The sanitisation benefits of the laundry detergent and/or fabric care compositions of the present invention can be evaluated by the Minimum Inhibitory Concentration (MIC) as described in Tuber. Lung. Dis. 1994 Aug ; 75 (4) : 286-90 ; J. Clin. Microbiol. 1994 May ; 32 (5) : 1261-7 and J. Clin. Microbiol. 1992 Oct ; 30 (10) : 2692-7.

Other suitable antimicrobial compounds with an hydroxyl, carboxyl or aldehyde moiety are described in Parfums Cosmétiques Actualités No 125, Nov, 1995, 51-4. Other suitable antibacterial components are the Nerodol which can for example be linked to the carboxylic groups or succinic acid linked to the alcohol group of the deposition aid and/or linking region. A further example are the compounds Cipamaldehyde and/or Beta ionone which can form for example a Shiff base or ß-amino ketone with the NH2 groups of the deposition aid and/or linking region.

Also suitable are the microbicidally active ingredients described in the handbook of Disinfectants and Antiseptics edited by J. M.

Preferably, the levels of the hygiene entity should be such that they prevent bacterial and fungi growth on fabrics, rather than merely preventing growth within the laundry detergent and/or fabric care compositions per se.

When encompassed in the compositions of the present invention, these hygiene entities will be generally comprised at a level of from 0. 00001 % to 20%, preferably from 0. 00001 % to 5% by weight of the total composition.

Insect Control agent

Further suitable chemical entities for the laundry detergent and/or fabric care compositions of the present invention are insect control entities wherein at least one benefit agent is an insect control agent, linked to a deposition aid.

It has surprisingly been determined that such insect control entities in the laundry detergent and/or fabric care compositions of the present invention, provide a much longer lasting insect control by the slow release of the insect control agent.

Moreover, the insect control entities upon binding to the fabric, cause disruption of the fabric fibers leading to the laundry soils/stains and fibers being more accessible to polymer activity. Therefore, it has been found that the laundry detergent and/or fabric care compositions of the present invention combining these insect control entities with a polymer, provide enchanced insect control performance, as well as improved fabric cleaning and/or anti-redeposition of soils and/or augmented color care and/or whiteness maintenance and/or enhanced fabric softness.

Such insect control agents are linked to the deposition aid and/or linking region preferably via a weak bond in order to release upon time the active material. For example, these materials can be linked to the NH2 group present in the deposition aid and/or linking region via a Shiff base or Michael reaction.

The term insect control agent refers to both insecticides and insect repellents either individually or as mixtures. Examples of insect repellents can be found in Kirk-Othmer Encyclopedia of Chemical technology, Fourth edition, volume 13, pages 474 to 478. Suitable insect repellents include aldehyde based compounds such as Citronellal and Rotundial, ene one based compounds such as Butopyronoxyl (Indalone TM), benzyl benzoate, bioallethrin and dimethrin, N, N- diethyl toluamide ("DEET"), N, N-diethyl benzamide, p-menthane-3, 8-diol, 1S, 3S, 4S, 6S-carene-3, 4diol (Sumitomo-US5, 130, 136), 1-piperidinecarboxylic acid, 2- (2-hydroxyethyl)-, 1-methylpropylester, 1- (3cyclohexen-1-yl carbonyl)- 2methylpiperidine, 1- (3-cyclohexen-1-yi carbonmyl) piperidine, N, N-diethyl mandelamide, isopulegol hydrate, ethyl-3 (N-butyl-N-acetyl) aminopropionate, diisopropyladipate, a-biasal, psearmint oil, benzyl alcohol, N, N- diethylphenylacetamide, vitamin E, citronella oil, coconut oil, cedar oil, geraniol, lemon grass oil, thyme oil, reosemary oil, mint oil, geranium oil, eugenol, 3-

acetyl-2- (2-, 6-dimethyl-5-heptenyl) oxazolidine, (2- hydroxymethylcyclohexyl) acetic acid lactone and eucalyptol. Other insect control agents are based on pyrethroid insecticides, in particular 3-phenoxybenzyl-DL- cis, trans-3- (2, 2-dichlorovinyl)-2, 2-dimethylcyclopropane-carboxylate (permethrin). W098/17772 describes the insect repellent agent 3- (N- butylacetamino) ethyl propionate for use in detergents.

Preferred insect repellents are aldehyde based compounds such as Citronellal and Rotundial.

When encompassed in the compositions of the present invention, these insect control entities are generally comprised at a level of from 0. 1 % to 40%, preferably from 0. 1 % to 10% by weight of the total composition.

Bleaching agent A further suitable chemical entity for the compositions of the present invention, is a bleaching entity wherein at least one benefit agent is a bleaching agent, linked to a deposition aid. Said bleaching agent can be selected from hydrophilic bleach activators, hydrophobic bleach activators, metal catalysts and/or photoactivated bleaches.

It has been surprisingly found that the bleaching action with such bleaching entities within the laundry detergent and/or fabric care compositions of the present invention, results in improved and increased stain/soil bleaching/removal and whiteness maintenance. Without wishing to be bound by theory, it is believed that improved stain/soil bleaching/removal and whiteness maintenance results in the generation of oxygen radicals, peracetic acid or peracid perhydrolysis occurring very close to the fabric. Said peracetic acid or peracid is less dilute in the wash solution due to the bleach entity of the present invention being very efficiently deposited onto the fabric and thereby improving the bleaching action on the fabric. Moreover, the bleaching action from the bleaching entity also lead to laundry soils and stains becoming solubilized due to the bleach activity oxidizing a-polar groups into more polar groups. This increased solubility of the laundry soils/stains provides greater accessibility for the polymer to the soils and stains, thereby resulting in improved polymer performance. Furthermore, It has been surprisingly found that the bleaching

entity disrupts the fabric fibers making the fibers more susceptible to polymer activity. Therefore, it has been found that the laundry detergent and/or fabric care compositions combining the bleaching entities with a polymer, provide improved stain/soil bleaching/removal and whiteness maintenance coupled with enhanced polymer activity such as fabric cleaning, anti-redeposition of soils, color care, whiteness maintenance, and fabric softness.

Preferably, the bleach activator is linked to the deposition aid via a linking region, more preferably via a polyreactive linking region. Without wishing to be bound by theory, it is believed that the presence of such a linking region provides flexibility of movement to the bleach activator therefore enabling it to perform more efficient its bleaching action on the fabric fibers.

1) Hydrophilic bleach activator : For example, Tetra Acetyl Ethylene Diamine (TAED) is a current bleach activator used in laundry detergent and forms peracetic acid in presence of H202. It is known that the two NH2 groups of the Ethylene Diamine are diacetylated to form TAED. Without wishing to be bound by theory, it is believed that the diacetylation of the free NH2 groups of the deposition aid and/or linking region, forms a substantive fabric hydrophilic bleach activator. Hydrophilic bleach activator of the TAED type can be linked for example via a diacetylation reaction to any NH2 groups of the deposition aid and/or linking region of the present invention.

2) Hydrophobic bleach activators such as Nonanoyl benzene sulphonate, are current bleach activators used in laundry detergent. It has been surprisingly found that the phenolic moiety can be replace by the one present in the tyrosine amino acid present in the deposition aid and/or linking region. Active hydrophobic bleach activator precursors such as nonanyl unit can be linked to the phenol group of an amino acid such as tyrosine present in the peptidic deposition aid and/or linking region. Similarly, if there is no phenol entity available in the deposition aid and/or linking region, a phenol unit can be linked to a group NH2 in this deposition aid and/or linking region. Hydrophobic bleach activators in general can be linked to the deposition aid and/or linking region for example by a reaction on NH2 groups.

Other examples of suitable hydrophobic bleach activators are nonanoyloxybenzene-sulfonate (NOBS, described in US 4, 412, 934), 3, 5,-

trimethylhexanoloxybenzenesulfonate (ISONOBS, described in EP 120, 591) or pentaacetylglucose (PAG) or Phenolsulfonate ester of N-nonanoyl-6- aminocaproic acid (NACA-OBS, described in W094/28106), which are perhydrolyzed to form a peracid as the active bleaching species, leading to improved bleaching effect.

Also suitable bleach activators are the activators based on a caprolactam leaving group such as benzoyl caprolactam and quaternary ammonium hexanoyl caprolactam ; the imides activators such as N-nonanoyl-N-methyl acetamide and unsymetrical acyclic imide bleach activator of the following formula as disclosed in the Procter & Gamble co-pending patent applications US serial No. 60/022, 786 (filed July 30, 1996) and No. 60/028, 122 (filed October 15, 1996) : wherein R1 is a C7-C13 linear or branched chain saturated or unsaturated alkyl group, R2 is a Cl-C8, linear or branched chain saturated or unsaturated alkyl group and R3 is a Cl-C4 linear or branched chain saturated or unsaturated alkyl group. These bleach activators can for example be linked to any NH2 groups of the polyreative linking region.

Also suitable are the pre-fromed peracid such as nonylamido peroxy adipic acid and N, N-phtaloylaminoperoxy caproic acid and the Di-acyl peroxides such as dobenzoyl peroxide.

3) Metal catalysts : A third type of bleach activator that can be encompassed in the bleaching entity of the present invention, are the below described metal catalysts. For example, these catalysts can be linked via their capping cyclo azo moieties to NH2 groups of the deposition aid and/or linking region.

Examples of Metal-containing catalysts for use in bleach compositions, include cobalt-containing catalysts such as Pentaamine acetate cobalt (III) salts and manganese-containing catalysts such as those described in EPA 549 271 ; EPA 549 272 ; EPA 458 397 ; US 5, 246, 621 ; EPA 458 398 ; US 5, 194, 416 and US 5, 114, 611. Bleaching composition comprising a peroxy compound, a manganese-containing bleach catalyst and a chelating agent is described in the patent application No 94870206. 3.

4) Photoactivated bleach : Another group of suitable bleach activators that can be encompassed in the bleaching entity of the present invention, are the photoactivated bleaches. For example, the linking can be achieved between the NH2 groups of and the benzyls groups of these photoactivated bleaches, activated via a preliminary bromination.

Suitable photoactivated bleaching agents are the sulfonated zinc and/or aluminum phthalocyanines. These materials can be deposited upon the substrate during the washing process. Upon irradiation with light, in the presence of oxygen, such as by hanging clothes out to dry in the daylight, the sulfonated zinc phthalocyanine is activated and, consequently, the substrate is bleached. Preferred zinc phthalocyanine and a photoactivated bleaching process are described in U. S. Patent 4, 033, 718. Typically, the compositions herein will contain about 0. 025% to about 1. 25%, by weight of sulfonated zinc phthalocyanine.

In addition to this bleaching entity, the compositions of the present invention can further comprise bleaching species such as hydrogen peroxide, PB1, PB4 and percarbonate with a particle size of 400-800 microns, typically be present at levels of from about 1 % to about 25%.

When encompassed in the compositions of the present invention, these bleaching entities will be generally comprised at a level of from 0. 001% to 40%, preferably from 0. 1 % to 10% by weight of the total composition.

Fabric softening agents For the purpose of the present invention, further suitable chemical entities are fabric softening entities wherein at least one benefit agent is a fabric softening agent, linked to a deposition aid. It has been surprisingly found that such fabric softening entities within the laundry detergent and/or fabric care compositions of the present invention, provide anti-wrinkling, anti-bobbling and anti-shrinkage properties to fabrics, as well as fabric softness.

In recent years, consumer desirability for durable press fabric garments, particularly cotton fabric garments, has risen. Durable press garments include

those garments which resist wrinkling of the fabric both during wear and during the laundering process. Durable press garments can greatly decrease the hand work associated with laundering by eliminating ironing sometimes necessary to prevent wrinkling of the garment. However, in most commercially available durable press fabrics, the fabric's ability to resist wrinkling is reduced over time as the garment is repeatedly worn and laundered. Therefore, the fabric softening entities of the present invention aid in eliminating this problem by providing excellent anti-wrinkling and softeness properties due to effective desposition of the fabric softening entity on the fabric.

Without wishing to be bound by theory, it is believed that the binding of the deposition aid of the fabric softening entity to the fabric fibers results in loosening of and increased accessibility to soils and stains. In addition, the binding of the deposition aid loosens Ca++ salts from the fabric surface, which are known to give a"harsh"feeling to the fabric. Therefore, the combined activity the fabric softening entity and a softener polymer such as a flocculant, leads to improved fabric softness.

Thus, it has been found that the laundry detergent and/or fabric care compositions of the present invention combining these fabric softening entites with a polymer, provide all benefits obtained from the fabric softening entities, and improved polymer benefits such as fabric cleaning, anti-redeposition of soils, color care, whiteness maintenance, and fabric softness.

Suitable fabric softening agents are dialkyl units that can be linked for example, by dialkylation of the NH2 groups comprised in the deposition aid and/or linking region. Preferably such fabric softening entities will not comprise a weak bond.

Dialkyl units suitable for the compositions of the present invention can be extracted from the following cationic softening surfactants currently used in the laundry detergent and/or fabric care context.

The alkyl, or alkenyl chain must contain at least 11 carbon atoms, preferably at least 16 carbon atoms. The chain may be straight or branched. Specific examples of the alkyl or alkenyl chains herein include : 1) N, N-di (tallowyl-oxy-ethyl) ; 2) N, N-di (2-tallowyloxy-2-oxo-ethyl) ; 3) N, N-di (2-tallowyloxyethylcarbonyloxyethyl) ; 4) N- (2-tallowoyloxy-2-ethyl)-N- (2-tallowyloxy-2-oxo-ethyl) ; 5) N- (2-tallowyloxy-2-oxoethyl)-N- (tallowyl) ; and

6) 1, 2-ditallowyloxy ; and mixtures of any of the above materials.

Preferred alkyl chains for the purpose of the present invention N, N-di (tallowoyl- oxy-ethyl), where the tallow chains are at least partially unsaturated.

Other suitable fabric softening agents include quaternary ammonium softening compounds having a solubility in water at pH2. 5 and 20°C of less than 10g/l. It is particularly advantageous if the fabric softening agent is a quaternary ammonium compound in which at least one long chain alkyl group is connected to the quaternary ammonium compound via at least one ester link. Suitable cationic softener are described in US4, 137, 180 (Naik) and W093/23510.

Also suitable as softening components are clay or silicone.

Suitable clays include a three layered smectite clay, preferably having a cationic exchange capacity as described in GB 1, 400, 898 and in USP 5, 019, 292.

Especially preferred are clays which are 2 : 1 layer phyllosilicates possessing a lattice charge efficiency in the range of 0. 2 to 0. 4g equivalent per half unit cell as described in EP 350 288 (Unilever).

Also encompassed in the present invention are any polymeric lubricant suitable for softening a fabric. These include silicone and in particular those described in GB1, 549, 180 ; EP 459 821 (Unilever) and EP 459 822 (Unilever).

When encompassed in the present invention, these improved fabric softening entities will be generally comprised at a level of from 0. 5% to 50%, preferably from 1 % to 30, more preferably from 2% to 15% by weight of the composition.

Dye fixative agents Further suitable chemical entities for the compositions of the present invention are dye fixative entities wherein at least one benefit agent is a dye fixative agent, linked to a deposition aid.

It has been surprisingly found that such dye fixative entities in the laundry detergent and/or fabric care compositions of the present invention, provide enchanced anti-wear properties and colour appearance. Indeed, coloured

garments have a tendency to wear and show colour appearance losses. A portion of this wear and colour appearance loss may be attributed to abrasion in the laundering process, particularly in automatic washing machines and automatic laundry dryers. Therefore, it has been found that the laundry detergent and/or fabric care compositions combining these dye fixative entities with a polymer, reduce wear and colour appearance loss, and provide improved fabric cleaning and/or anti-redeposition of soils and/or augmented colour care and/or whiteness maintenance and/or enhanced fabric softness.

Without wishing to be bound by theory, it is believed that the binding of the dye fixative entity to the fabric surface disrupt the filber, resulting in increased accessibility to the laundry soils/stains and fabric fibers. This leads to better dye fixative performance of the chemical entity and to increased polymer benefits. Preferably, such dye fixative chemical entity is combined with a dye transfer inhibitor polymer, resulting in superior color care and wear appearance.

Dye fixative agents are well-known, commercially available materials which are designed to improve the appearance of dyed fabric by minimising the loss of dye from fabrics due to washing. Many dye fixatives are cationic, and are based on various quaternized or otherwise cationically charged organic nitrogen compounds. Fixatives are available under various trade names from several suppliers. Representative examples include : CROSCOLOR PMF (July 1981, Code No. 7894) and CROSCOLOR NOFF (January 1988, Code No. 8544) from Crosfield ; INDOSOL E-50 (February 27, 1984, Ref. No. 6008. 35. 84 ; polyethyleneamine-based) from Sandoz ; SANDOFIX TPS, which is also available from Sandoz and is a preferred polycationic fixative for use herein and SANDOFIX SWE (cationic resinous compound), REWIN SRF, REWIN SRF-O and REWIN DWR from CHT-Beitlich GMBH. Other cationic dye fixative agents are described in"Aftertreatments for improving the fastness of dyes on textile fibres"by Christopher C. Cook (REV. PROG. COLORATION Vol. 12, 1982).

Other dye fixative agents suitable for use in the present invention are ammonium compounds such as fatty acid-diamine condensates e. g. the hydrochloride, acetate, metosulphate and benzyl hydrochloride of oleyldiethyl aminoethylamide, oleylmethyl-diethylenediaminemethsulphate, monostearyl-ethylene diaminotrimethylammonium methosulphate and oxidised products of tertiary

amines ; derivatives of polymeric alkyldiamines, polyamine-cyanuric chloride condensates and aminated glycerol dichlorohydrins.

When encompassed in the compositions of the present invention, these dye fixing entities will be generally comprised at a level of from 0. 01% to 30%, preferably from 0. 1% to 15% by weight of the total composition.

Soil release agents A further suitable chemical entity for the compositions of the present invention is a soil release entity wherein at least one benefit agent is a soil release agent, linked to a deposition aid.

It has been surprisingly found that such soil release agents in the laundry detergent and/or fabric care compositions of the present invention, provide better deposition of the soil release agent onto the fabric and therefore better soil removal performance. Without wishing to be bound by theory, it is believed that the combination of such soil release entities with a polymer can enhance the removal of laundry soils and stains. Without wishing to be bound by theory, it is bleived that the soil release entity interacts with the fabric surface in such a way that the accessibility of the laundry soils/stains and fabric fibers is greatly increased. Consequently, a significantly enhanced fabric cleaning is obtained resulting from improved soil release/removal by the combined activity of the soil release entity and the polymer. In addition, the polymer provide further anti- redeposition of soils, color care, whiteness maintenance and fabric softness, thanks to the increased accessibility.

Suitable soil release agents for use in the present invention include ethylene glycols oligomers, polyethylene glycol and derivatives such as transesterified polyethylene glycols, and propylene polyoxy ethylene. Other suitable soil release agents useful in compositions of the present invention are conventionally copolymers or terpolymers of terephthalic acid with ethylene glycol and/or propylene glycol units in various arrangements. Examples of such polymers are disclosed in the commonly assigned US Patent Nos. 4116885 and 4711730 and European Published Patent Application No. 0 272 033. A particular preferred polymer in accordance with EP-A-0 272 033 has the formula

(CH3 (PEG) 43) 0. 75 (POH) 0. 25 [T-PO) 2. 8 (T-PEG) 0. 4] T (PO- H) 0. 25 ( (PEG) 43CH3) 0. 75 where PEG is- (OC2H4) 0-, PO is (OC3H6O) and T is (pcOC6H4CO).

Also very useful are modified polyesters as random copolymers of dimethyl terephthalate, dimethyl sulfoisophthalate, ethylene glycol and 1-2 propane diol, the end groups consisting primarily of sulphobenzoate and secondarily of mono esters of ethylene glycol and/or propane-diol. The target is to obtain a polymer capped at both end by sulphobenzoate groups,"primarily", in the present context most of said copolymers herein will be end-capped by sulphobenzoate groups.

However, some copolymers will be less than fully capped, and therefore their end groups may consist of monoester of ethylene glycol and/or propane 1-2 diol, thereof consist"secondarily"of such species.

The selected polyesters herein contain about 46% by weight of dimethyl terephthalic acid, about 16% by weight of propane-1. 2 diol, about 10% by weight ethylene glycol about 13% by weight of dimethyl sulfobenzoic acid and about 15% by weight of sulfoisophthalic acid, and have a molecular weight of about 3. 000. The polyesters and their method of preparation are described in detail in EPA 311 342.

Other suitable soil release agents are those of U. S. 4, 968, 451, November 6, 1990 to J. J. Scheibel and E. P. Gosselink : such ester oligomers can be prepared by (a) ethoxylating alkyl alcohol, (b) reacting the product of (a) with dimethyl terephthalate ("DMT") and 1, 2-propylene glycol ("PG") in a two-stage transesterification/oligomerization procedure and (c) reacting the product of (b) with sodium metabisulfite in water ; the nonionic end-capped 1, 2- propylene/polyoxyethylene terephthalate polyesters of U.

Another preferred soil release agent is a sulfonated end-capped type described in US 5, 415, 807.

When encompassed in the compositions of the present invention, these soil release entities are generally comprised at a level of from 0. 01 % to 20%, preferably from 0. 1% to 5% by weight of the total composition.

Brightener agents Also suitable as a chemical entity for the laundry detergent and/or fabric care compositions of the present invention is a brightener entity wherein at least one benefit agent is a brightener, linked to a deposition aid.

It has been suprisingly found that such brightener entities provide increased deposition of the brightener agent onto the fabric and therefore better whiteness maintenance performance. Without wishing to be bound by theory, it is believed that the specific combination of a brightener entity and a polymer interact with the fabric surface in such a way that the accessibility of the laundry soils/stains and fabric fibers is greatly increased. Consequently, a significantly enhanced fabric whiteness maintenance is obtained coupled with enhanced polymer activity.

Therefore, the laundry detergent and/or fabric care compositions of the present invention combining these brightener agents and a polymer, provide enhanced fabric whiteness maintenance, and additional polymer activity benefits such as improved fabric cleaning, anti-redeposition of soils, color care, and/or fabric softness.

Suitable brighteners for compositions of the present invention are : -Carbocycles types of compounds such as distyrylbenzenes, distyrylbiphenyls and divinylstibenes, -Triazinylaminostilbenes, -Stilbenyl-2H-triazoles such as stilbenyl-2H-naphtol [1, 2-d] triazoles and

The brightener agents, for example of the Coumarin type, can be attached to the NH2 group or to an amido group from the deposition aid and/or linking region.

Preferred are the bleach-stable brighteners such as 1, 4-di (2- methylaminostyryl) benzene.

Highly preferred brighteners are the specific brighteners of copending European Patent application No.

95201943. 8.

It has been surprisingly found that various brighteners not currently used in the detergent field could also be used in the present invention thanks to their increased fabric substantivity, in particular during a softening-through-the-wash process. Preferably, such brightener entities will not comprise a weak bond.

When encompassed in the compositions of the present invention, these brigthener agents will be generally comprised at a level of from 0. 001% to 10%, preferably 0. 005% to 3. 5% by weight of the total composition.

Other suitable benefit agents Also suitable as chemical entities for the compositions of the present invention are latex and resin entities. These latex and resin entities comprise a benefit

agent wherein at least one benefit agent is a latex or resin agent, linked to a deposition aid. Latex is defined as a material suitable for refining the drape of fabric. Resins prevent the formation of pills on the fabrics.

Without wishing to be bound by theory, it is believed that these chemical entities upon binding to the fabric surface increase the accessibility of laundry soils/ stains and fabric fibers. Therefore, laundry detergent and/or fabric care compositions comprising these chemical entities combined with a polymer provide refining of fabric drape, prevention of pill formation, and improved polymer activity such as fabric cleaning, anti-redeposition of soils, color care, whiteness maintenance, and fabric softness.

Suitable latex materials include a polyvinylacetate homopolymer such as 9802 (Vinamul). Suitable resins are Knittex BE from Ciba-Geigy or silicas such as Crosanol NS from Crosfiled.

THE POLYMER The second essential element of the laundry detergent and/or fabric care compositions according to the present invention, is a polymer. Suitable polymers for use in the compositions of the present invention include soil release polymers, dispersants, anti-redeposition polymers, dye transfer inhibitors, flocculants, and/or mixtures thereof.

Soil release polymer A suitable polymer for the purpose of the present invention is a soil release polymer. Soil release polymer activity results in release/removal of laundry soils and stains from the fabric surface. Without wishing to be bound by theory, it is believed that the binding of the chemical entities of the present invention, to the fabric surface leads to disruption of the fabric fibers causing loosening of laundry soils and stains. As a result, the soil release polymer has increased accessibility

to the laundry soils and stains, and therefore the soil release polymers are able to more effectively and efficiently remove the soils and stains from the fabric fibers. This results in effective and efficient removal of soils and stains and in augmented fabric whiteness. Therefore, it has been found that the laundry detergent and/or fabric care compositions of the present invention comprising a chemical entity and a soil release polymer, provide improved fabric cleaning and whiteness maintenance.

Suitable soil release polymers for the laundry detergent and/or fabric care compositions of the present invention are ethylene glycols oligomers, polyethylene glycol and derivatives such as transesterified polyethylene glycols, propylene polyoxy ethylene, and conventionally copolymers or terpolymers of terephthalic acid with ethylene glycol and/or propylene glycol units in various arrangements. Examples of such polymers are disclosed in the commonly assigned US Patent Nos. 4116885 and 4711730 and European Published Patent Application No. 0 272 033. A particular preferred polymer in accordance with EP-A-0 272 033 has the formula : (CH3 (PEG) 43) 0. 75 (POH) 0. 25 [T-PO) 2. 8 (T-PEG) 0. 4] T (PO- H) 0. 25 ( (PEG) 43CH3) 0. 75 where PEG is- (OC2H4) 0-, PO is (OC3H6O) and T is (pcOC6H4CO).

Also very useful are modified polyesters as random copolymers of dimethyl terephthalate, dimethyl sulfoisophthalate, ethylene glycol and 1-2 propane diol, the end groups consisting primarily of sulphobenzoate and secondarily of mono esters of ethylene glycol and/or propane-diol. The target is to obtain a polymer capped at both end by sulphobenzoate groups,"primarily", in the present context most of said copolymers herein will be end-capped by sulphobenzoate groups.

However, some copolymers will be less than fully capped, and therefore their end groups may consist of monoester of ethylene glycol and/or propane 1-2 diol, thereof consist"secondarily"of such species.

The selected polyesters herein contain about 46% by weight of dimethyl terephthalic acid, about 16% by weight of propane-1. 2 diol, about 10% by weight ethylene glycol about 13% by weight of dimethyl sulfobenzoic acid and about 15% by weight of sulfoisophthalic acid, and have a molecular weight of about

3. 000. The polyesters and their method of preparation are described in detail in EPA 311 342.

Other suitable soil release polymers are those of U. S. 4, 968, 451, November 6, 1990 to J. J. Scheibel and E. P. Gosselink : such ester oligomers can be prepared by (a) ethoxylating alkyl alcohol, (b) reacting the product of (a) with dimethyl terephthalate ("DMT") and 1, 2-propylene glycol ("PG") in a two-stage transesterification/oligomerization procedure and (c) reacting the product of (b) with sodium metabisulfite in water ; the nonionic end-capped 1, 2- propylene/polyoxyethylene terephthalate polyesters of U. S. 4, 711, 730, December 8, 1987 to Gosselink et al, for example those produced by transesterification/oligomerization of poly (ethyleneglycol) methyl ether, DMT, PG and poly (ethyleneglycol) ("PEG") ; the partly-and fully-anionic-end-capped oligomeric esters of U.

Another preferred soil release polymer is a sulfonated end-capped type described in US 5, 415, 807. Further suitable soil release agents are disclosed in U. S. Patent Nos 5, 728, 671 ; 5, 691, 298 ; 5, 599, 782 ; 5, 182, 043 ; 4, 956, 447 ; 4, 976, 879 ; 4, 925, 577, 4, 861, 5121 ; 4, 000, 093 ; 3, 959, 230 ; 3, 893, 9294, 201, 824 ; 4. 240, 918 ; 4, 525, 524 ; 4, 579, 681 ; 4, 220, 918 and 4, 787, 989 ; EP 279, 134 ; EP 457, 205A ; EP 219 048 and DE 2, 335, 044.

Soil release agents are generally comprised at a level of from 0. 01% to 10%, preferably from 0. 1% to 5%, more preferably from 0. 2% to 3% by weight of the total composition.

Dispersants

A suitable polymer for the purpose of the present invention is a dispersant. Dispersants prevent the deposition onto the fabric surface of soils from the laundry wash solution. Without wishing to be bound by theory, it is believed that the binding of the chemical entities of the present invention, to the fabric surface leads to disruption of the fabric fibers causing loosening of soil particles therefrom. As a result, the dispersant has increased accessibility to the soil particles, and therefore the dispersant is able to more effectively absorb onto the surface of the soil particles preventing their agglomeration. This results in a barrier being formed between the soil particles and the fabric surface, and thus reduces the deposition of soil particles onto fabrics, thereby aiding in fabric cleaning and maintaining the whiteness of the fabric. Consequently, it has been found that the laundry detergent and/or fabric care compositions of the present invention comprising a chemical entity and a dispersant, provide improved fabric cleaning and whiteness maintenance.

Suitable dispersants for use in laundry detergent and/or fabric care compositions of the present invention are polyalkyleneimine dispersants. Examples of such suitable dispersants can be found in European Patent Application Nos 111, 965, 111, 984 and 112, 592 ; U. S. Patent Nos 4, 597, 898 ; 4, 548, 744 and 5, 565, 145.

Another polymeric material which can be included is polyethylene glycol (PEG).

PEG can exhibit dispersing agent performance as well as act as a clay soil removal-antiredeposition agent. Typical molecular weight ranges for these purposes from about 500 to about 100, 000, preferably from about 1, 000 to about 50, 000, more preferably from about 1, 500 to about 10, 000.

Further suitable dispersants are polyaspartate and polyglutamate dispersing agents may also be used, especially in conjunction with zeolite builders.

Dispersing agents such as polyaspartate preferably have a molecular weight (avg.) of about 10, 000.

Water-soluble organic salts such as homo-or co-polymeric acids or their salts, in which the polycarboxylic acid comprises at least two carboxyl radicals separated from each other by not more than two carbon atoms. Polymers of this type are disclosed in GB-A-1, 596, 756. Examples of such salts are polyacrylates of MW 2000-5000 and their copolymers with maleic anhydride, such copolymers having a molecular weight of from 1, 000 to 100, 000. Especially, copolymer of acrylate and methylacrylate such as the 480N having a molecular weight of 4000, at a

level from 0. 5-20% by weight of composition can be added in the laundry detergent and/or fabric care compositions of the present invention.

Other suitable dispersants can be lime soap peptiser compounds, which have preferably a lime soap dispersing power (LSDP), as defined hereinafter of no more than 8, preferably no more than 7, most preferably no more than 6. The lime soap peptiser compound is preferably present at a level from 0. 0001% to 20% by weight.

A numerical measure of the effectiveness of a lime soap peptiser is given by the lime soap dispersant power (LSDP) which is determined using the lime soap dispersant test as described in an article by H. C. Borghetty and C. A. Bergman, J.

Am. Oil. Chem. Soc., volume 27, pages 88-90, (1950). This lime soap dispersion test method is widely used by practitioners in this art field being referred to, for example, in the following review articles ; W. N. Linfield, Surfactant science Series, Volume 7, page 3 ; W. N. Linfield, Tenside surf. det., volume 27, pages 159-163, (1990) ; and M. K. Nagarajan, W. F. Masler, Cosmetics and Toiletries, volume 104, pages 71-73, (1989). The LSDP is the % weight ratio of dispersing agent to sodium oleate required to disperse the lime soap deposits formed by 0. 025g of sodium oleate in 30ml of water of 333ppm CaCo3 (Ca : Mg=3 : 2) equivalent hardness.

Polymeric lime soap peptisers suitable for use herein are described in the article by M. K. Nagarajan, W. F. Masler, to be found in Cosmetics and Toiletries, volume 104, pages 71-73, (1989).

Hydrophobic bleaches such as 4- [N-octanoyl-6-aminohexanoyl] benzene sulfonate, 4- [N-nonanoyl-6-aminohexanoyl] benzene sulfonate, 4- [N-decanoyl-6- aminohexanoyl] benzene sulfonate and mixtures thereof ; and nonanoyloxy benzene sulfonate together with hydrophilic/hydrophobic bleach formulations can also be used as lime soap peptisers compounds.

Surfactants may also be used as lime soap peptiser compounds, such as certain amine oxides, betaines, sulfobetaines, alkyl ethoxysulfates and ethoxylated alcohols. Exemplary surfactants having a LSDP of no more than 8 for use in accord with the present invention include C16-Cl8 dimethyl amine oxide, C12- C1g alkyl ethoxysulfates with an average degree of ethoxylation of from 1-5, particularly C12-C15 alkyl ethoxysulfate surfactant with a degree of ethoxylation of amount 3 (LSDP=4), and the C14-C1s ethoxylated alcohols with an average

degree of ethoxylation of either 12 (LSDP=6) or 30, sold under the tradenames Lutensol A012 and Lutensol A030 respectively, by BASF GmbH.

Dispersing agants are generally incorporated into the laundry detergent and/or fabric care compositions of the present invention at a level from 0. 0001-20%, preferably 0. 5-20% by weight of the total composition.

Anti-redeposition polymers A suitable polymer for the purpose of the present invention is an anti-redeposition polymer. Anti-redeposition polymers prevents the redeposition of soils from solution onto the fabric surface. Without wishing to be bound by theory, it is believed that the binding of the chemical entities of the present invention to the fabric surface, leads to disruption of the fabric fibers. As a result, the anti- redeposition polymers have an increase accessibility to the fabric fibers, and therefore are able to more efficiently absorb onto the fabric surface. This enables the anti-redeposition polymers to effectively change the surface charge density of the fabric, preventing the redeposition of soils from solution onto the fabric surface. Therefore, it has been found that the laundry detergent and/or fabric care compositions of the present invention comprising a chemical entity and an anti-redeposition polymer, provide improved fabric cleaning and whiteness maintenance.

Anti-redeposition polymers suitable for use in the laundry detergent and/or fabric care compositions of the present invention, include cellulose derivatives such as methylcellulose, carboxymethylcellulose and hydroxyethylcellulose, and homo-or co-polymeric polycarboxylic acids or their salts. Polymers of this type include the polyacrylates and maleic anhydride-acrylic acid copolymers, as well as copolymers of maleic anhydride with ethylene, methylvinyl ether or methacrylic acid, the maleic anhydride constituting at least 20 mole percent of the copolymer.

Other suitable anti-redeposition polymers are alkoxylated polycarboxylates such as those prepared from polyacrylates, useful herein to provide additional grease removal performance. Such materials are described in WO 91/08281 and PCT 90/01815 at p. 4 et seq., incorporated herein by reference. Chemically, these

materials comprise polyacrylates having one ethoxy side-chain per every 7-8 acrylate units. The side-chains are of the formula- (CH2CH20) m (CH2) nCH3 wherein m is 2-3 and n is 6-12. The side-chains are ester-linked to the polyacrylate"backbone"to provide a"comb"polymer type structure. The molecular weight can vary, but is typically in the range of about 2000 to about 50, 000. Such alkoxylated polycarboxylates can comprise from 0. 05% to 10% by weight of the compositions herein.

These anti-redeposition polymers are normally used at levels of from 0. 05% to 10%, more preferably from 0. 75% to 8%, most preferably from 1% to 6% by weight of the compositions of the present invention.

Dye transfer inhibitor polymers A suitable polymer for the purpose of the present invention is a dye transfer inhibiting (DTI) polymer. Dye transfer inhibiting polymers inhibit the transfer of dyes from colored fabrics onto other fabrics washed therewith. Without wishing to be bound by theory, it is believed that binding of the chemical entity of the present invention to the fabric surface results in disruption of the fabric fibers, and therefore enabling the dye transfer inhibitor polymers to have greater accessibility to the fabric dyes. These polymers have the ability to complex or adsorb fugitive dyes washed out of dyed fabrics before the dyes have the opportunity to become attached to other articles in the wash. Therefore, it has been found the laundry detergent and/or fabric care compositions of the present invention comprising a chemical entity and a dye transfer inhibiting polymer, provide improved color care and whiteness maintenance benefits.

Suitable polymeric dye transfer inhibitors include polyamine N-oxide polymers, copolymers of N-vinylpyrrolidone and N-vinylimidazole, polyvinylpyrrolidone polymers, polyvinyloxazolidones and polyvinylimidazoles or mixtures thereof. a) Polyamine N-oxide polymers : The polyamine N-oxide polymers suitable for use contain units having the following structure formula : P

Preferred class of these polyamine N-oxides are the polyamine N-oxides having the general formula (I) wherein R is an aromatic, heterocyclic or alicyclic groups wherein the nitrogen of the N-0 functional group is part of said R group.

Examples of these classes are polyamine oxides wherein R is a heterocyclic compound such as pyrridine, pyrrole, imidazole and derivatives thereof.

Floculant polymers A suitable polymer for the purpose of the present invention is a floculant polymer. Flocculant polymers provide fabric softening benefits by lubricating the fabric surface, by enhancing the deposition of for e. g. smectite clay. Without wishing to be bound by theory, it is believed that the binding of the chemical entity of the present invention, to the fabric surface leads to disruption of the fabric fibers. The floculant polymers have increased accessibility to the fabric fibers, deposit more clay, resulting in more efficient lubrication of the fabric surface. Lubrication of the fabric surface leads to fabric softness by reducing the "fuzz"formation or surface pilling which occurs on the fabric surface from washing. Such surface pilling causes increased fabric wear and leads to a harsh feeling of the fabric. Therefore, it has been found that the laundry detergent and/or fabric care compositions of the present invention comprising a chemical entity and a floculant polymer, provide enhanced fabric softness.

Suitable floculant polymers for use in the laundry detergent and/or fabric care compositions of the present invention include high molecular weight polyethylene oxides such as desceibed in EP 299 575 and EP 313 146.

Floculant polymers are normally used at levels of from 0. 1% to 2%, more preferably from 0. 15% to 1. 5% by weight of the compositions of the present invention.

95/10603, published April 95. Also suitable are amylases described in EP 277 216, W095/26397 and W096/23873 (all by Novo Nordisk).

Cleaning compositions which incorporate mutant amylases are described in W094/02597, Novo Nordisk A/S published February 03, 1994. See also W095/10603, Novo Nordisk A/S, published April 20, 1995.

The amylolytic enzymes are incorporated in the laundry detergent and/or fabric care compositions of the present invention at a level of from 0. 0001% to 2%, preferably from 0. 00018% to 0. 06%, more preferably from 0. 00024% to 0. 048% pure enzyme by weight of the compositions.

The above-mentioned enzymes may be of any suitable origin, such as vegetable, animal, bacterial, fungal and yeast origin. Origin can further be mesophilic or extremophilic (psychrophilic, psychrotrophic, thermophilic, barophilic, alkalophilic, acidophilic, halophilic, etc.). Purified or non-purified forms of these enzymes may be used. Also included by definition, are mutants of native enzymes. Mutants can be obtained e. g. by protein and/or genetic engineering, chemical and/or physical modifications of native enzymes. Common practice as well is the expression of the enzyme via host organisms in which the genetic material responsible for the production of the enzyme has been cloned.

Said enzymes are normally incorporated in the laundry detergent and/or fabric care compositions at levels from 0. 0001 % to 2% of pure enzyme by weight of the compositions. The enzymes can be added as separate single ingredients (prills, granulates, stabilized liquids, etc. containing one enzyme) or as mixtures of two or more enzymes (e. g. cogranulates).

Other suitable detergent ingredients that can be added are enzyme oxidation scavengers which are described in Copending European Patent application 92870018. 6 filed on January 31, 1992. Examples of such enzyme oxidation scavengers are ethoxylated tetraethylene polyamines.

Such chelating agents can be selected from the group consisting of amino carboxylates, amino phosphonates, polyfunctionally-substituted aromatic chelating agents and mixtures therein, all as hereinafter defined. Without intending to be bound by theory, it is believed that the benefit of these materials is due in part to their exceptional ability to remove iron and manganese ions from washing solutions by formation of soluble chelates.

Amino carboxylates useful as optional chelating agents include ethylenediaminetetracetates, N-hydroxyethylethylenediaminetriacetates, nitrilo- triacetates, ethylenediamine tetraproprionates, triethylenetetraamine- hexacetates, diethylenetriaminepentaacetates, and ethanoldiglycines, alkali metal, ammonium, and substituted ammonium salts therein and mixtures therein.

Amino phosphonates are also suitable for use as chelating agents in the compositions of the invention when at least low levels of total phosphorus are permitted in detergent compositions, and include ethylenediaminetetrakis (methylenephosphonates) as DEQUEST. Preferred, these amino phosphonates do not contain alkyl or alkenyl groups with more than about 6 carbon atoms. Polyfunctionally-substituted aromatic chelating agents are also useful in the compositions herein. See U. S. Patent 3, 812, 044, issued May 21, 1974, to

Connor et al. Preferred compounds of this type in acid form are dihydroxydisulfobenzenes such as 1, 2-dihydroxy-3, 5-disulfobenzene.

If utilized in the compositions of the present invention, these chelating agents will generally be comprised at a level of from 0. 1% to 15%, preferably from 0. 1% to 3. 0% by weight of the composition.

Suds suppressor Another optional ingredient is a suds suppressor, exemplified by silicones, and silica-silicone mixtures. Silicones can be generally represented by alkylated polysiloxane materials while silica is normally used in finely divided forms exemplified by silica aerogels and xerogels and hydrophobic silicas of various types. These materials can be incorporated as particulates in which the suds suppressor is advantageously releasably incorporated in a water-soluble or water-dispersible, substantially non-surface-active detergent impermeable carrier. Alternatively the suds suppressor can be dissolve or dispersed in a liquid carrier and applied by spraying on to one or more of the other components.

A preferred silicone suds controlling agent is disclosed in Bartollota et al. U. S.

Patent 3 933 672. Other particularly useful suds suppressors are the self- emulsifying silicone suds suppressors, described in German Patent Application DTOS 2 646 126 published April 28, 1977. An example of such a compound is DC-544, commercially available from Dow Corning, which is a siloxane-glycol copolymer.

Organic fabric softening agents such as the water-insoluble tertiary amines or dilong chain amide materials are incorporated at levels of from 0. 5% to 5% by weight, normally from 1 % to 3% by weight whilst the high molecular weight polyethylene oxide

materials and the water soluble cationic materials are added at levels of from 0. 1% to 2%, normally from 0. 15% to 1. 5% by weight. These materials are normally added to the spray dried portion of the composition, although in some instances it may be more convenient to add them as a dry mixed particulate, or spray them as molten liquid on to other solid components of the composition.

Bleaching agent Other detergent ingredients that can be included in the laundry detergent and/or fabric care compositions of the present invention include bleaching agents.

The bleaching agent component for use herein can be any of the bleaching agents useful for cleaning compositions including oxygen bleaches as well as others known in the art. The bleaching agent suitable for the present invention can be an activated or non-activated bleaching agent.

Such materials are normally added at 0. 5-10% by weight of the finished product, preferably 1-5% by weight.

Also suitable activators are acylated citrate esters such as disclosed in Copending European Patent Application No. 91870207. 7.

Useful bleaching agents, including peroxyacids and bleaching systems comprising bleach activators and peroxygen bleaching compounds for use in the compositions of the present invention are described in our co-pending applications USSN 08/136, 626, PCT/US95/07823, W095/27772, W095/27773, W095/27774 and W095/27775.

The hydrogen peroxide may also be present by adding an enzymatic system (i. e., an enzyme and a substrate therefore) which is capable of generating hydrogen peroxide at the beginning or during the washing and/or rinsing process.

Such enzymatic systems are disclosed in EP Patent Application 91202655. 6 filed October 9, 1991.

Others Other components such as soil-suspending agents, soil-release agents, optical brighteners, abrasives, bactericides, tarnish inhibitors, and/or coloring agents may be employed.

Other useful polymeric materials are the polyethylene glycols, particularly those of molecular weight 1000-10000, more particularly 2000 to 8000 and most preferably about 4000. These are used at levels of from 0. 20% to 5% more preferably from 0. 25% to 2. 5% by weight. These polymers and the previously mentioned homo-or co-polymeric polycarboxylate salts are valable for improving whiteness maintenance, fabric ash deposition, and cleaning performance on clay, proteinaceous and oxidizable soils in the presence of transition metal impurities.

It is well known in the art that free chlorine in tap water rapidly deactivates the enzymes comprised in detergent compositions. Therefore, using chlorine scavenger such as perborate, ammonium sulfate, sodium sulphite or polyethyleneimine at a level above 0. 1% by weight of total composition, in the formulas will provide improved through the wash stability of the detergent enzymes. Compositions comprising chlorine scavenger are described in the European patent application 92870018. 6 filed January 31, 1992.

Method of washing The compositions of the invention may be used in essentially any washing, cleaning and/or fabric care methods, including soaking methods, pre-treatment methods, methods with rinsing steps for which a separate rinse aid composition may be added and post-treatment methods.

The process described herein comprises contacting fabrics with a laundering solution in the usual manner and exemplified hereunder. A conventional laundry method comprises treating soiled fabric with an aqueous liquid having dissolve or dispensed therein an effective amount of the laundry detergent and/or fabric care composition. The method of cleaning is preferably carried out at 5°C to 95°C, especially between 10°C and 60°C. The pH of the treatment solution is preferably from 7 to 12.

Example 1 According to the present invention, this example illustrates the coupling of a perfume citral, hygiene agent glutaraldehyde or insect control agent citronellal to a CBD, as a deposition aid.

The reaction at equal mol takes place in mild conditions (pH 6 to 9. 5, from 1 to 48hours/See for example Wirth, P at al 1991 Biorg. Chem 19, 133, 1991 and Chamow SM et al Bioconjugate chem, 4, 133 1994). The chemicals such as perfume (citral), insect control agent (citronellal) and hygiene agent (glutaraldehyde) are linked to NH2 groups of the CBD, linking region and/or polyreactive linking region via Schiff's base reaction. The reaction could also be completed in anhydrous ethanol that contain a drying agent such as Sodium Sulphate.

In case the CBD possesses more than one Lysine or there is a polyreactive linking region comprising more than one lysine, the reaction is identical with the appropriate number of chemicals per CBD. For example 10 equivalent of aldehyde will be added per mol of CBD from familly III that contain more than 10 Lysines.

For example, the CBD having at least one Lysine, has a NH2 reactive moiety to be linked to perfume. The CBD is non volatile and does not change the character of the aldehyde.
