BACKGROUND OF THE INVENTION Formulators of fabric care and laundry detergent compositions include various ingredients, imper alia surfactants. cationic softening actives, anti-static agents, dye transfer inhibitors, and bleach-damage mitigating agents, for the purpose of improving cleaning, fabric appearance, fabric feel, fabric color and to extend the duration of fabric life. Ingredients which are added to these compositions must not only provide a benefit, but must be compatible with a variety of product forms, i. e high density granules, liquid dispersions, isotropic liquids including clear. colorless/translucent liquids which may include principal solvents inter alia 1,2- hexanediol, 2.2.4-trimethyl-1, 3-pentanediol (TMPD).

Many adjunct ingredients which provide fabric enhancement benefits are highly fabric substantive and. therefore, once deposited on the fabric surface remain with the fabric thereby

providing the intended benefit until chemically altered or until displaced by a more fabric substantive material. High molecular weight modified polyalkyleneimines have been used in granular and liquid detergent compositions as well as rinse-added fabric conditioning compositions to mitigate fabric damage. These highly fabric substantive ingredients can be deposited onto fabric at various optimal times, for example, in the alkaline laundry wash liquor or the near neutral pH environment of the laundry rinse cycle. Once deposited they serve a variety of purposes depending upon the absolute structure of the polyalkyleneamine or polyalkyleneimine and whether the polymeric amine is modified (for example, ethoxylated).

Color integrity is an important aspect of fabric enhancement. When certain polyamines are deposited onto fabric they enhance color fidelity via various mechanisms. Other polyamines intercept peroxygen bleaching agents at the fabric surface.

Consumers use bleach-containing compositions when washing colored fabric as well as white fabric because the use of a bleaching material satisfies the consumers need to feel that the fabric has been"thoroughly cleaned". Therefore, there is a long felt need to provide colored fabric with protection against the pejorative effects of laundry-added bleaching materials. In addition, there is a need for materials which will be highly water soluble or water dispersible, while exhibiting a high degree of fabric substantivity. And there is also a need for a material which will provide a high level of fabric protection on an efficient per unit weight basis.

DETAILED DESCRIPTION OF THE INVENTION

The present invention relates to fabric care compositions whether rinse-added fabric conditioning compositions, rinse-added fabric care compositions, pre-treatment or post-treatment compositions, or laundry detergent compositions. The compositions of the present invention provide increased color fidelity benefits to fabric in addition to other desirable benefits, inter alia fabric cleanliness, fabric softness, fabric integrity, fabric appearance, fabric lubricity. The fabric care and/or fabric enhancement compositions may take any form, for example, solids (i. e., powders, granules, extrudates), gels, thixotropic liquids, liquids (i. e., dispersions, isotropic solutions), preferably the rinse added fabric conditioning compositions take the form of liquid dispersions or isotropic liquids.

For the purposes of the present invention the term"fabric care"is the broadest term which refers to the present compositions and encompasses any composition which improves the appearance or wear properties of fabric, especially clothing. For the purposes of the present invention fabric care compositions are divided into several categories, inter alia, laundry detergent compositions, fabric appearance, each of which are typically characterized by the presence of an ingredient or the lack thereof. For example"laundry detergent compositions"are required to comprise one or more detersive surfactants while"fabric softener compositions"are required to comprise one or more cationic quaternary ammonium compounds. However, because a composition comprises a particular class of compound, inter alia, detersive surfactant, does not relegate nor limit the composition to a single category under the description of the present invention. Also compositions do not require all delineating ingredients which may characterize a particular embodiment.

For the purposes of the present invention the terms"fabric enhancement"and"fabric care"are used interchangeably throughout the present specification and stand equally well for one another. Fabric enhancement/fabric care is achieved when the properties inter alia color, fiber integrity of the garment are conserved (that is no further damage is done during the laundry process) or the damaging process is reversed and the fabric appears more like its original form.

In addition the term"fabric care"may refer to the laundry detergent compositions of the present invention as well as the fabric conditioning compositions.

It has now been surprisingly discovered that low molecular weight propyleneimines, preferably polypropyleneimines (backbones having a MW < 250 daltons) or cyclic amines, preferably comprising a N, N'-bis-1,4-substituted piperazine ring, are highly fabric substantive and, in addition, are capable of intercepting bleaching agents which may approach the fabric surface. It has also been surprisingly discovered that a 3-carbon propylene spacing between nitrogen atoms of linear portions of the polyamine molecules provides for improved

discrimination in the chelation of unwanted copper ions in solution over desirable copper which is included in the dye systems of fabric.

In the broadest sense, the compositions of the present invention comprise from about 0.01%, preferably from about 0.75%, more preferably from 2%, most preferably from about 5% to about 50%, preferably to about 35%, more preferably to about 20%, most preferably to about 15% by weight, of the herein described polyamines. However, depending upon the particular embodiment, inter alia, liquid or solid, the type of co-ingredients, inter alia, optional solvents, the level of polyamine will vary from formulation to formulation. For example, the most preferred level above, which is from about 5%, is typically too high for laundry detergent compositions.

The following describe in detail the essential elements of the present invention.

Linear Polvamines The enhanced fabric appearance compositions of the present invention may comprise one or more propyleneimines, propyleneamines, polypropyleneimines (branched), or polypropyleneamines (linear) which contain modified or unmodified backbone nitrogen units.

For the purpose of the present invention the terms"polyamines having propylene spacing", "polypropyleneimine", and"polypropyleneamine"are used alone, together, or interchangeably throughout the present specification to refer to the hereinbelow described modified or unmodified amines and each term is meant to stand equally well for the others unless a distinction is specifically pointed out. The term"polypropyleneimine"is used throughout the present specification to refer to any polyamine, linear or branched, which comprises at least one propylene unit.

The polyamines of the present invention have the formula: wherein R is 1, 2-propylene) 1,3-propylene, and mixtures thereof ; preferably 1,3-propylene.

Each R'is independently hydrogen, methyl, ethyl, or an alkyleneoxy unit having the formula: wherein R'is ethylene, 1,2-propylene, 1,2-butylene, or mixtures thereof ; preferably R3 is ethylene or 1,2-propylene, more preferably 1,2-propylene. R 4is hydrogen, C,-C4 alkyl, and mixtures thereof ; preferably hydrogen. R'may comprise any mixture of alkyleneoxy units. R 2is hydrogen, R',-RN (R') 2, and mixtures thereof ; preferably at least one R2 is hydrogen when n is equal to 2.

The integer n is 1 or 2. For"peralkylated"amines each Rl and R2 will be independently selected from methyl or ethyl.

Most prefered linear polyamine has a backbone wherein R is 1,3-propylene, R2 is hydrogen, methyl, or alkoxy, and n is equal to 2, N, N'-bis (3-aminopropyl)-1,3-propylenediamine (TPTA). This preferred backbone can then be substituted or left unsubstituted in a manner which affords the formulator the maximal fabric benefit and compatibility of the low molecular weight amine with the particular embodiment. As a non-limiting example, when R'and R are each equal to hydrogen, dye fixative properties, in certain liquid fabric conditioning embodiments comprising bleach, are maximal.

Examples of preferred polyamines of the present invention having propylene unit backbones have the following backbone formulae prior to modification: and wherein those of ordinary skill in the art will recognize that depending upon the synthetic procedure used to prepare the polypropyleneamine backbones, varying amounts of both the linear and branched materials will be present in the final product admixture. The backbones of the linear polyamines of the present invention comprise at least one 1,3-propylene unit, preferably at least two 1,3-propylene units.

For certain formulations, polyamines which comprise alkylated polyamines are preferred, for example, tetramethyl dipropylenetriamine having the formula: the permethylated dipropylenetriamine having the formula:

and the mono-methylated dipropylenetriamine having the formula: For the purposes of the present invention, when a backbone nitrogen is referred to as "unmodified"the nitrogen contains only hydrogen atoms."Modified"polyamines have one or more alkyleneoxy units as described herein above. Preferred substituents are ethyleneoxy, 1,2- propyleneoxyl, 2-butyleneoxy and mixtures thereof, more preferably 1,2-propyleneoxy.

Cvclic Amines The enhanced fabric appearance compositions of the present invention may comprise one or more cyclic polyalkyleneamines which contain modified or unmodified backbone nitrogen units. For the purpose of the present invention the terms"polyamines having propylene spacing", "polypropyleneimine", and"polypropyleneamine"are used alone, together, or interchangeably throughout the present specification to refer to the hereinbelow described modified or unmodified amines which comprise at least one 3-carbon propylene spacer between adjacent backbone nitrogen atoms. The term"N, N'-bis (aminoalkylene) cyclic amines"is also used throughout the present specification to refer to any of the low molecular weight polyamines which provide fabric appearance benefits.

The low molecular weight cyclic polyamines of the present invention comprise polyamine backbones having the formula: R-L-R wherein L is a linking unit, said linking unit comprising a ring having at least 2 nitrogen atoms; R is hydrogen,- (CH2) kN (R') 2, and mixtures thereof ; wherein each index k independently has the value from 2 to 4, preferably 3. Preferably the backbone of the cyclic amines including R units is 200 daltons or less.

Each R'is independently hydrogen, C,-C, alkyl, or an alkyleneoxy unit having the formula:

wherein R3 is ethylene, 1,2-propylene, 1,2-butylene, or mixtures thereof ; preferably R'is ethylene or 1,2-propylene, more preferably 1,2-propylene. R4 is hydrogen, C,-C4 alkyl, and mixtures thereof ; preferably hydrogen. R'may comprise any mixture of alkyleneoxy units.

Preferred polyamines of the present invention have the formula: (RI) 2N- (CH2) k- L- (CH2) k-N (R') 2 wherein the indices k each have the same value and each R'is the same unit.

Preferably the backbone of the cyclic amines of the present invention comprise a N, N'- bis-substituted 1,4-piperazine ring having the formula: wherein each Rs is independently hydrogen, C,-C4 alkyl, Cl-C4 hydroxyalkyl, C,-C4 aminoalkyl, or two R units of the same carbon atom are bonded to oxygen thus forming a carbonyl group (C=O) wherein the carbon atom is a ring atom, and mixture thereof. Examples of carbonyl containing rings which comprise L units are 1,4-diketopiperizines.

Preferably the backbones of the polyamines of the present invention, prior to modification, have the formula: wherein each R unit is- (CH2) 3NHo and each Rs unit is hydrogen.

However, the cyclic units may be substituted on only one ring nitrogen as in the case wherein one R unit is hydrogen, and the other R unit is- (CH2) kNH2, for example, the piperazine having the formula: The backbones of the cyclic polyamines of the present invention preferably comprise at least one 1, 3-propylene unit, more preferably at least two 1,3-propylene units.

For the purposes of the present invention, when a backbone nitrogen is referred to as "unmodified"the nitrogen contains only hydrogen atoms."Modified"polyamines have one or more substituent units as described herein above. Preferably when the backbone units are modified all of the nitrogens are modified. Preferred alkyleneoxy substituents are ethyleneoxy, 1,2-propyleneoxy, and mixtures thereof, more preferably 1,2-propyleneoxy.

Effects of Backbone Modifications The polyamines of the present invention provide a multiplicity of fabric care and fabric enhancement benefits. Chlorine scavenging benefits are achieved with all of the polyamines independent of the degree of branching (i. e. the number of primary, secondary, and tertiary nitrogens).

It has been surprisingly found that bleach protection is enhanced when the backbone nitrogens are substituted with one or more modifications which comprise an alkyleneoxy unit having the general formula: wherein said unit is R3 as defined herein above. However, if the formulator wishes to enhance the dye fixation properties of the presently disclosed polyamines, the backbone nitrogens will not be substituted with an alkyleneoxy unit.

The negative chelation effects, inter alia, extraction of heavy metal ions associated with fabric dyes, are overcome and optimal dye integrity is achieved when the polyamine backbone comprises C2-C3, preferably C3 (1,3-propylene) units, and the backbone nitrogens are per- substituted, preferably by sterically hindered substituents. The choice of nitrogen substituents is left to the formulator, the choice being affected by the other properties which are desired and to the compatibility of the polyamine within the final formulation.

FORMULATIONS Rinse-added, Pre-treatment, and Post-treatment Fabric Enhancement Compositions The ingredients, including the low molecular weight polyamines, which comprise the compositions of the present invention vary depending upon the type of fabric enhancement benefit the formulator wishes to provide. The following are non-limiting examples of compositions and their corresponding fabric appearance benefits.

Bleach Damage Mediation The compositions of the present invention afford protection of fabric dyes to the effects of both peroxygen and chlorine bleaches. Typically, as a pre-treatment, post-treatment, or rinse-

added composition, the bleach protecting agents are applied to fabric. These ingredients then protect the fabric from dye loss and/or dye damage due to the presence of bleaching agents in subsequent wash cycles. Due to the high substantivity of may of the presently disclosed ingredients, even when only treated once by the compositions of the present invention, protection is afforded for several wash cycles.

It has been surprisingly discovered that the combination of one or more low molecular weight polyamines of the present invention in combination with a hydrophobic dispersant, preferably a hydrophobic dispersant as disclosed in U. S. 5,565,145 Watson et al., issued October 15,1996, provide fabric color care protection. A preferred embodiment comprises: a) from about 0.01%, preferably from about 0.75%, more preferably from 2%, most preferably from about 5% to about 50%, preferably to about 35%, more preferably to about 20%, most preferably to about 15% by weight, of a low molecular weight linear polyamine, cyclic polyamine, or mixtures thereof, as described herein above; b) from about 0.1%, preferably from about 5%, more preferably form about 10% to about 80%, preferably to about 50%, more preferably to about 25% by weight, of a hydrophobic polyamine dispersant having the formula: wherein B is a continuation of the polyamine backbone by branching; R is preferably ethylene; R'is preferably an ethyleneoxy unit having the formula: -(CH2CH20) XH wherein x has the average value from 0.5 to about 10, preferably x is from 3 to about 7; the values of the indices w, x, and y are such that the molecular weight of the backbones prior to ethoxylation are preferably at least about 1200 daltons, more preferred backbone has a molecular weight of about 1800 daltons; and c) the balance carriers and adjunct ingredients.

The typical bleaching agent mediating polyamines of the present invention comprise at least about 50%, preferably at least about 80% linear backbones.

Fabric Anti-Encrustation and Stiffness The compositions of the present invention affords increased softness to fabric, especially cotton fabric which can suffer mechanical breakdown (loss of fabric structure integrity) due to the deposition of scale (calcium deposits) upon the fabric. The deposition of scale modifies the

fabric surface and prevents cationic softeners from having their fullest affect at providing a porous"breathable"substrate surface. Typically, as a rinse-added composition, the scale mediating agents are applied to fabric. These ingredients then protect the fabric from unwanted deposition of calcium, magnesium, etc. ions which preclude the efficient deposition onto the fabric surface of other fabric enhancement ingredients.

It has been surprisingly discovered that the combination of one or more low molecular weight polyamines of the present invention in combination with a chelant, preferably hydroxyethane-1,1-diphosphonate (HEDP), BAYHIBIT ex Baeyer, provides mediation of calcium and other scale comprising deposits. Preferably these ingredients are combined with one or more hydrophobic dispersants, preferably a hydrophobic dispersant as disclosed in U. S.

A preferred embodiment comprises: a) from about 0.01%, preferably from about 0.75%, more preferably from 2%, most preferably from about 5% to about 50%, preferably to about 35%, more preferably to about 20%, most preferably to about 15% by weight, of a low molecular weight linear polyamine, cyclic polyamine, or mixtures thereof, as described herein above; b) from about 0.1 %, preferably from about 5%, more preferably form about 10% to about 80%, preferably to about 50%, more preferably to about 25% by weight, of a chelant, hydrotrope, or other alkaline earth cation mediating agent; and c) the balance carriers and adjunct ingredients.

The fabric softener system is modified depending upon the type of fabric softener composition, inter alia, isotropic liquid, substrate-delivered. The combination of a fabric softening system and a modified polyamine of the present invention is sufficient to provide fabric anti-static and enhanced fabric protection.

ISOTROPIC LIQUIDS One type of preferred embodiment of the present invention is the clear, translucent, isotropic liquid fabric softening composition. In order to form said compositions a stabilizing system is necessary, said stabilizing system comprising: i) from about 0.25%, preferably from about 0.5%, more preferably from about 1%, most preferably from about 1.5% to about 13.5%, preferably to about 10%, more preferably to about 7%, most preferably to about 5% by weight of an organic solvent; and ii) from about 0.25%, preferably from about 0.5%, more preferably from about 1%, most preferably from about 2.5% to about 20%, preferably to about 15%, more preferably to about 12%, still more preferably to about 10%, most preferably to about 8% by weight, of a bilayer modifier.

The following are non-limiting examples of the components which comprise a stabilizing system for clear, translucent, isotropic liquid fabric softening compositions.

Organic/Principal Solvent A wide range of organic solvents are effective including those heretofore characterized as "principal solvents"which fall within the broadest Clog P limits used to define principal solvents.

Modifications of the ClogP ranges can be achieved by adding electrolyte and/or phase stabilizers as taught in copending U. S. Pat. Application SN 09/309,128, filed May 10,1999 by Frankenbach, et al.

Principal solvents are selected to minimize solvent odor impact in the composition and to provide a low viscosity to the final composition. For example, isopropyl alcohol is flammable and has a strong odor. n-Propyl alcohol is more effective, but also has a distinct odor. Several butyl alcohols also have odors but can be used for effective clarity/stability, especially when used as part of a principal solvent system to minimize their odor. The alcohols are also selected for optimum low temperature stability, that is they are able to form compositions that are liquid with acceptable low viscosities and translucent, preferably clear, down to about 50°F (about 10°C),

more preferably down to about 40°F (about 4.4°C) and are able to recover after storage down to about 20°F (about 6.7°C).

Other suitable solvents can be selected based upon their octanol/water partition coefficient (P). Octanol/water partition coefficient of a solvent is the ratio between its equilibrium concentration in octanol and in water. The partition coefficients of the solvent ingredients of this invention are conveniently given in the form of their logarithm to the base 10, logP.

The logP of many ingredients has been reported; for example, the Pomona92 database, available from Daylight Chemical Information Systems, Inc. (Daylight CIS), Irvine, California, contains many, along with citations to the original literature. However, the logP values are most conveniently calculated by the"CLOGP"program, also available from Daylight CIS. This program also lists experimental logP values when they are available in the Pomona92 database.

The"calculated logP" (ClogP) is determined by the fragment approach of Hansch and Leo (cf., A. Leo, in Comprehensive Medicinal Chemistry, Vol. 4, C. Hansch, P. G. Sammens, J. B. Taylor and C. A. Ramsden, Eds., p. 295, Pergamon Press, 1990, incorporated herein by reference). The fragment approach is based on the chemical structure of each ingredient, and takes into account the numbers and types of atoms, the atom connectivity, and chemical bonding. The ClogP values, which are the most reliable and widely used estimates for this physicochemical property, are preferably used instead of the experimental logP values in the selection of the principal solvent ingredients which are useful in the present invention. Other methods that can be used to compute ClogP include, e. g., Crippen's fragmentation method as disclosed in J. Chem. Inf.

Comput. Sci., 27,21 (1987); Viswanadhan's fragmentation method as disclose in J. Chem. Inf.

Comput. Sci., 29,163 (1989); and Broto's method as disclosed in Eur. J. Med. Chem.-Chim.

Theor., 19,71 (1984).

The principal solvents herein are selected from those having a ClogP of from-2.0 to 2.6, preferably from-1.7 to 1.6, and more preferably from-1.0 to 1.0., The most preferred solvents can be identified by the appearance of the diluted fabric treatment compositions. These diluted compositions comprise vesicular dispersions of fabric softener which contain on average more uni-lamellar vesicles than conventional fabric softener compositions, which contain predominantly multilamellar vesicles. The larger the proportion of uni-lamellar vs. multilamellar vesicles, the better the compositions seem to perform. These compositions provide surprisingly good fabric softening as compared to similar compositions prepared in the conventional way with the same fabric softener active.

Operable solvents have been disclosed, listed under various listings, e. g., aliphatic and/or alicyclic diols with a given number of carbon atoms; monols; derivatives of glycerine; alkoxylates of diols; and mixtures of all of the above can be found in U. S. 5,759,990 Wahl et al., issued June 2,1998; U. S. 5,747,443 Wahl et al., issued May 5,1998 and PCT application WO 97/03169 published on 30 January 1997, said patents and application being incorporated herein by reference.

Principal solvents preferred for improved clarity at 50 °F are 2-ethyl-1,3-hexanediol, 1,2- hexanediol; 1,2-pentanediol; hexylene glycol; 1,2-butanediol; 1,4-cyclohexanediol; pinacol; 1,5- hexanediol; 1,6-hexanediol; and/or 2,4-dimethyl-2,4-pentanediol.

Bilayer Modifiers Bilayer modifiers are compounds which allow the formation of stable formulations at lower and substantially reduced solvent levels even to the point of, surprisingly, eliminating solvent in some compositions.

An advantage of the bilayer modifiers disclosed herein is the lower levels of principal solvents and/or a wider range of principal solvents can be used to provide clarity. For example, without a bilayer modifier, the ClogP of the principal solvent system as disclosed herein would typically be limited to a range of from about 0.15 to about 0.64 as disclosed in U. S. 5,747,443 Wahl et al., issued May 5,1998. It is known that higher ClogP compounds, up to about 1 can be used when combined with other solvents as disclosed in copending provisional application Serial No. 60/047,058, filed May 19,1997 and refiled PCT/US98/10167 on May 18,1998, in the names of H. B. Tordil, E. H. Wahl, T. Trinh, M. Okamoto, and D. L. Duval, or with nonionic surfactants, and especially with the phase stabilizers disclosed herein as previously disclosed in Docket No. 7039P, filed March 2,1998, Provisional Application S. N. 60/076,564, and refiled as, the inventors being D. L. DuVal, G. M. Frankenbach, E. H. Wahl, T. Trinh, H. J. M. Demeyere, J. H.

Shaw and M. Nogami. Title: Concentrated, Stable, Translucent or Clear Fabric Softening Compositions, both of said applications being incorporated herein by reference. With the bilayer modifier present, the level of principal solvent can be less and/or the ClogP range that is usable is broadened to include from about-2.0 to about 2.6, more preferably from about-1.7 to about 1.6, and even more preferably from about-1.0 to about 1.0.

Fabric softening actives, especially those actives or compositions comprising multiple hydrophobes tend to form bilayers. When these bilayers and the water between the bilayers are sufficiently flexible, the composition can become a single-phase isotropic system comprising a bicontinuous bilayer or sponge phase.

There are many ways to improve flexibility such that single-phase isotropic bicontinuous systems with improved stability are achieved. Using fabric softening actives with low phase transition temperatures enhances flexibility of the bilayer since the actives are fluid. The phase transition temperature can be lowered by several means, for instance by incorporating branching and/or unsaturation in the hydrophobe of fabric softener actives and employing mixtures of fabric softener actives. Using principal solvents, particularly those within the most preferred Clog P ranges enhances the flexibility of both the water and the bilayer because these principal solvents, especially in the more preferred ranges, have the ability to migrate between the water where they can break up the water hydrogen bond structure and the bilayer interface where they can promote net zero curvature at the bilayer interface. Net zero curvature is more readily achieved when the head group of an amphiphile (or group of amphiphiles) and the tail moiety of a amphiphile (or group of amphiphiles) occupy equal or nearly equal volume areas. When the head group and tail moiety area volumes are nearly equal, there is no driving force to cause the surfactant interface to curve in either direction and then the surfactant interface becomes bicontinuous (Surfactants and Interfacial Phenomena, Second Edition, M. J. Rosen). Often cosurfactants are used to make oil in water bicontinuous micro-emulsions (Surfactants and Interfacial Phenomena, Second Edition, M. J. Rosen). A similar principle operates with fabric softener bilayers. Diquats, by their very nature have large head groups because the two charged amine moieties are both very water miscible and therefore, it is helpful to have a principal solvent that can migrate to the interface acting to'fill in'for the tail volume, to achieve zero curvature necessary to drive the system into the isotropic bicontinuous phase. Bilayer modifiers can also act as'fillers'that together with the fabric softener active push the system into a state of zero curvature necessary to drive the system into the isotropic bicontinuous phase. With the appropriate bilayer modifier, the principal solvent or organic solvent can be substantially reduced even to the point, in some cases, of surprisingly eliminating the need to add solvent that is not a part of the polyquaternary, preferably diquaternary, ammonium fabric softening active raw material because the solvent is only necessary to break the water structure and no longer necessary to act as a filler at the fabric softener bilayer surface. Unsaturation and/or branching in the components improves flexibility, thus facilitating the bending of the surface of the bilayer, when necessary.

Bilayer modifiers are highly desired optional components of clear compositions with low solvent or zero added solvent. Preferably these compounds are amphiphilic with a water miscible head group attached to a hydrophobic moiety.

The mid-chain branched surfactants are preferably mixtures which comprise a surfactant system. Therefore, when the surfactant system comprises an alkoxylated surfactant, the index m indicates the average degree of alkoxylation within the mixture of surfactants. As such, the index m is at least about 0.01, preferably within the range of from about 0.1, more preferably from about 0.5, most preferably from about 1 to about 30, preferably to about 10, more preferably to about 5.

Dye fixing agents, or"fixatives", are well-known, commercially available materials which are designed to improve the appearance of dyed fabrics by minimizing the loss of dye from fabrics due to washing. Not included within this definition are components which can in some embodiments serve as fabric softener actives.

Many dye fixing agents are cationic, and are based on quatemized nitrogen compound or on nitrogen compounds having a strong cationic charge which is formed in situ under the conditions of usage. Cationic 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) ex Crosfield; INDOSOL E-50 (February 27,1984, Ref. No. 6008.35.84; polyethyleneamine-based) ex Sandoz; SANDOFIX TPS, ex Sandoz, is a preferred dye fixative for use herein. Additional non-limiting examples include SANDOFIX SWE (a cationic resinous compound) ex Sandoz, REWIN SRF, REWIN SRF-O and REWIN DWR ex CHT-Beitlich GMBH; Tinofix (D ECO, Tinofix (D FRD and Solfin (E ex Ciba-Geigy. A preferred dye fixing agent for use in the compositions of the present invention is CARTAFIX CB (g) ex Clariant.

Other cationic dye fixing agents are described in"Aftertreatments for Improving the Fastness of Dyes on Textile Fibres", Christopher C. Cook, Rev. Prog Coloration, Vol. XII, (1982).

The cellulose reactive dye fixatives may be suitably combined with one or more dye fixatives described herein above in order to comprise a "dye fixative system".

The term"cellulose reactive dye fixing agent"is defined herein as"a dye fixative agent which reacts with the cellulose fibers upon application of heat or upon a heat treatment either in situ or by the formulator". The cellulose reactive dye fixing agents suitable for use in the present invention can be defined by the following test procedure.

Cellulose Reactivity Test (CRT) Four pieces of fabric which are capable of bleeding their dye (e. g. 10 x 10 cm of knitted cotton dyed with Direct Red 80) are selected. Two swatches are used as a first control and a second control, respectively. The two remaining swatches are soaked for 20 minutes in an aqueous solution containing 1% (w/w) of the cellulose reactive dye fixing agent to be tested. The swatches are removed and thoroughly dried. One of the treated swatches which has been thoroughly dried, is passed ten times through an ironing calender which is adjusted to a"linen fabric"temperature setting. The first control swatch is also passed ten times through an ironing calender on the same temperature setting.

All four swatches (the two control swatches and the two treated swatches, one of each which has been treated by the ironing calender) are washed separately in Launder-O-Meter pots under typical conditions with a commercial detergent used at the recommended dosage for 1/2

hour at 60°C, followed by a thorough rinsing of 4 times 200 ml of cold water and subsequently line dried.

Color fastness is then measured by comparing the DE values of a new untreated swatch with the four swatches which have undergone the testing. DE values, the computed color difference, is defined in ASTM D2244. In general, DE values relate to the magnitude and direction of the difference between two psychophysical color stimuli defined by tristimulus values, or by chromaticity coordinates and luminance factor, as computed by means of a specified set of color-difference equations defined in the CIE 1976 CIELAB opponent-color space, the Hunter opponent-color space, the Friele-Mac Adam-Chickering color space or any equivalent color space. For the purposes of the present invention, the lower the DE value for a sample, the closer the sample is to the un-tested sample and the greater the color fastness benefit.

As the test relates to selection or a cellulose reactive dye fixing agent, if the DE value for the swatch treated in the ironing step has a value which is better than the two control swatches, the candidate is a cellulose reactive dye fixing agent for the purposes of the invention.

Typically cellulose reactive dye fixing agents are compounds which contain a cellulose reactive moiety, non limiting examples of these compounds include halogeno-triazines, vinyl sulphones, epichlorhydrine derivatives, hydroxyethylene urea derivatives, formaldehyde condensation products, polycarboxylates, glyoxal and glutaraldehyde derivatives, and mixtures thereof. Further examples can be found in"Textile Processing and Properties", Tyrone L. Vigo, at page 120 to 121, Elsevier (1997), which discloses specific electrophilic groups and their corresponding cellulose affinity.

The following"Crystal Growth Inhibition Test"is used to determine the suitability of a material for use as a crystal growth inhibitor.

Crystal Growth Inhibition Test (CGIT) The suitability of a material to serve as a crystal growth inhibitor according to the present invention can be determined by evaluating in vitro the growth rate of certain inorganic micro- crystals. The procedure of Nancollas et al., described in"Calcium Phosphate Nucleation and Growth in Solution", Prog. Crystal Growth Charact., Vol 3,77-102, (1980), incorporated herein by reference, is a method which is suitable for evaluating compounds for their crystal growth inhibition. The graph below serves as an example of a plot indicating the time delay (t-lag) in crystal formation afforded by a hypothetical crystal growth inhibitor. l B/« Without CGI/ Volume of baseadded (ML) With CGI b. t-lag TIME

The observed t-lag provides a measure of the compound's efficiency with respect to delaying the growth of calcium phosphate crystal. The greater the t-lag, the more efficient the crystal growth inhibitor.

Exemplarv Procedure Combine in a suitable vessel, 2.1M KCl (35 mL), 0.0175M CaCl, (50mL), 0.01M KH2P04 (50mL), and de-ionized water (350mL). A standard pH electrode equipped with a Standard Calomel Reference electrode is inserted and the temperature adjusted to 37° C while purging of the solution of oxygen. Once the temperature and pH are stabilized, a solution of the crystal growth inhibitor to be test is then added. A typical inhibitor test concentration is 1 x 10-6 M. The solution is titrated to pH 7.4 with 0.05M KOH. The mixture is then treated with 5 mL's of a hydroxyapatite slurry. The hydroxyapatite slurry can be prepared by digesting Bio-GelX HTP hydroxyapatite powder (100 g) in 1 L of distilled water the pH of which is adjusted to 2.5 by the addition of sufficient 6N HC1 and subsequently heating the solution until all of the hydroxyapatite is dissolved (heating for several days may be necessary). The temperature of the solution is then maintained at about 22° C while the pH is adjusted to 12 by the addition of a solution of 50% aqueous KOH. Once again the solution is heated and the resulting slurry is allowed to settle for two days before the supernatant is removed. 1.5 L of distilled water is added, the solution stirred, then after settling again for 2 days the supernatant is removed. This rinsing procedure is repeated six more time after which the pH of the solution is adjusted to neutrality using 2N HCI. The resulting slurry can be stored at 37°C for eleven months.

Crystal growth inhibitors which are suitable for use in the present invention have a t-lag of at least 10 minutes, preferably at least 20 minutes, more preferably at least 50 minutes, at a

concentration of 1 x 10'"M. Crystal growth inhibitors are differentiated form chelating agents by the fact that crystal growth inhibitors have a low binding affinity of heavy metal ions, i. e., copper.

For example, crystal growth inhibitors have an affinity for copper ions in a solution of 0.1 ionic strength when measured at 25° C, of less than 15, preferably less than 12.

The D unit can be part of the backbone itself as represented in the general formula: -P (D).- n or the D unit may be incorporated into the backbone as a pendant group to a backbone unit having, for example, the formula: However, the number of D units depends upon the formulation. For example, the number of D units will be adjusted to provide water solubility of the polymer as well as efficacy of dye transfer inhibition while providing a polymer which has fabric abrasion reducing properties. The molecular weight of the fabric abrasion reducing polymers of the present invention are from about 500, preferably from about 1,000, more preferably from about 100,000 most preferably from 160,000 to about 6,000,000, preferably to about 2,000,000, more preferably to about 1,000,000, yet more preferably to about 500,000, most preferably to about 360,000 daltons.

The fabric abrasion reducing polymers of the present invention can comprise any mixture of dye transfer inhibition units which provides the product with suitable properties.

The preferred polymers which comprise D units which are amide moieties are those which have the nitrogen atoms of the amide unit highly substituted so the nitrogen atoms are in effect shielded to a varying degree by the surrounding non-polar groups. This provides the polymers with an amphiphilic character. Non-limiting examples include polyvinyl-pyrrolidones, polyvinyloxazolidones, N, N-disubstituted polyacrylamides, and N, N-disubstituted polymethacrylamides. A detailed description of physico-chemical properties of some of these polymers are given in"Water-Soluble Synthetic Polymers: Properties and Behavior", Philip Molyneux, Vol. I, CRC Press, (1983) included herein by reference.

The amide containing polymers may be present partially hydrolyzed and/or crosslinked forms. A preferred polymeric compound for the present invention is polyvinylpyrrolidone (PVP).

This polymer has an amphiphilic character with a highly polar amide group conferring hydrophilic and polar-attracting properties, and also has non-polar methylene and methine

groups, in the backbone and/or the ring, conferring hydrophobic properties. The rings may also provide planar alignment with the aromatic rings in the dye molecules.

Warrington, Pennsylvania, PVP K-15, K-25, and K-30 and poly (2-ethyl-2-oxazoline) are available ex Aldrich Chemical Co., Inc., Milwaukee, Wisconsin.

OMM; polyvinylpyrrolidone-co-vinyl acetate, available ex BASF under the tradename LuviskolOO, available in vinylpyrrolidone: vinylacetate ratios of from 3: 7 to 7: 3.

Polymers Comprising N-oxide Units Another D unit which provides dye transfer inhibition enhancement to the fabric abrasion reducing polymers described herein, are N-oxide units having the formula: wherein R', R2, and R'can be any hydrocarbyl unit (for the purposes of the present invention the term"hydrocarbyl"does not include hydrogen atom alone). The N-oxide unit may be part of a polymer, such as a polyamine, i. e., polyalkyleneamine backbone, or the N-oxide may be part of a pendant group attached to the polymer backbone. An example of a polymer which comprises an the N-oxide unit as a part of the polymer backbone is polyethyleneimine N-oxide. Non-limiting

examples of groups which can comprise an N-oxide moiety include the N-oxides of certain heterocycles inter alia pyridine, pyrrole, imidazole, pyrazole, pyrazine, pyrimidine, pyridazine, piperidine, pyrrolidine, pyrrolidone, azolidine, morpholine. A preferred polymer is poly (4- vinylpyridine N-oxide, PVNO). In addition, the N-oxide unit may be pendant to the ring, for example, aniline oxide.

N-oxide comprising polymers of the present invention will preferably have a ratio of N- oxidized amine nitrogen to non-oxidized amine nitrogen of from about 1: 0 to about 1: 2, preferably to about 1: 1, more preferably to about 3: 1. The amount of N-oxide units can be adjusted by the formulator. For example, the formulator may co-polymerize N-oxide comprising monomers with non N-oxide comprising monomers to arrive at the desired ratio of N-oxide to non N-oxide amino units, or the formulator may control the oxidation level of the polymer during preparation. The amine oxide unit of the polyamine N-oxides of the present invention have a Pka less than or equal to 10, preferably less than or equal to 7, more preferably less than or equal to 6.

The average molecular weight of the N-oxide comprising polymers which provide a dye transfer inhibitor benefit to reduced fabric abrasion polymers is from about 500 daltons, preferably from about 100,000 daltons, more preferably from about 160,000 daltons to about 6,000,000 daltons, preferably to about 2,000,000 daltons, more preferably to about 360,000 daltons.

Polymers Comprising Amide Units and N-oxide Units A further example of polymers which are fabric abrasion reducing polymers which have dye transfer inhibition benefits are polymers which comprise both amide units and N-oxide units as described herein above. Non-limiting examples include co-polymers of two monomers wherein the first monomer comprises an amide unit and the second monomer comprises an N- oxide unit. In addition, oligomers or block polymers comprising these units can be taken together to form the mixed amide/N-oxide polymers. However, the resulting polymers must retain the water solubility requirements described herein above.

Molecular weight For all the above polymer of the invention, it most preferred that they have a molecular weight in the range as described herein above. This range is typically higher than the range for polymers which render only dye transfer inhibition benefits alone. Indeed, the high molecular weight enables the abrasion occurring subsequent to treatment with the polymer to be reduced, especially in a later washing procedure. Not to be bound by theory, it is believed that that this benefit is partly due to the high molecular weight, thereby enabling the deposition of the polymer on the fabric surface and providing sufficient substantivity that the polymer is able to remain adhered to the fabric during the subsequent use and washing of the fabric. Further, it is believed that for a

given charge density, increasing the molecular weight will increase the substantivity of the polymer to the fabric surface. Ideally the balance of charge density and molecular weight will provide both a sufficient rate of deposition onto the fabric surface and a sufficient adherence to the fabric during a subsequent wash cycle. Increasing molecular weight is considered preferable to increasing charge density as it allows a greater choice in the range of materials which are able to provide the benefit and avoids the negative impact that increasing charge density can have such as the attraction of soil and residue onto treated fabrics. It should be noted however that a similar benefit may be predicted from the approach of increasing charge density while retaining a lower molecular weight material.

Solvents or Liquid Carriers The compositions of the present invention may optionally comprise from about 10%, preferably from about 12%, more preferably from about 14% to about 40%, preferably to about 35%, more preferably to about 25%, most preferably to about 20% by weight of one or more solvents (liquid carriers). These solvents are further disclosed in WO 97/03169 incorporated herein by reference. The use of solvents is especially critical when formulating clear, isotropic liquid fabric conditioning compositions comprising cationic fabric softening actives. The solvent is selected to minimize solvent odor impact in the composition and to provide a low viscosity to the final composition. For example, isopropyl alcohol is not very effective and has a strong odor. n-Propyl alcohol is more effective, but also has a distinct odor. Several butyl alcohols also have odors but can be used for effective clarity/stability, especially when used as part of a ease of formulation solvent system to minimize their odor. The alcohols are also selected for optimum low temperature stability, that is they are able to form compositions that are liquid with acceptable low viscosities and translucent, preferably clear, down to about 40°F (about 4.4°C) and are able to recover after storage down to about 20°F (about 6.7°C).

The suitability of any solvent for the formulation of embodiments which are clear isotropic liquids, is surprisingly selective. Suitable solvents can be selected based upon their octanol/water partition coefficient (P) as defined in WO 97/03169.

However, any suitable clay/soil dispersent or anti-redepostion agent can be used in the laundry compositions of the present invention.

Electrolvte The fabric softening embodiments of the compositions of the present invention, especially clear, isotropic liquid fabric softening compositions, may also optionally, but preferably comprise, one or more electrolytes for control of phase stability, viscosity, and/or clarity. For example, the presence of certain electrolytes inter alia calcium chloride, magnesium chloride may be key to insuring initial product clarity and low viscosity, or may affect the dilution viscosity of liquid embodiments, especially isotropic liquid embodiments. Not wishing to be limited by theory, but only wishing to provide an example of a circumstance wherein the formulator must insure proper dilution viscosity, includes the following example. Isotropic or non-isotropic liquid fabric softener compositions can be introduced into the rinse phase of laundry operations via an article of manufacture designed to dispense a measured amount of said composition. Typically the article of manufacture is a dispenser which delivers the softener active only during the rinse cycle. These dispensers are typically designed to allow an amount of water equal to the volume of softener composition to enter into the dispenser to insure complete delivery of the softener composition. An electrolyte may be added to the compositions of the present invention to insure phase stability and prevent the diluted softener composition from "gelling out"or from undergoing an undesirable or unacceptable viscosity increase. Prevention of gelling or formation of a"swelled", high viscosity solution insures thorough delivery of the softener composition.

However, those skilled in the art of fabric softener compositions will recognize that the level of electrolyte is also influenced by other factors inter alia the type of fabric softener active, the amount of principal solvent, and the level and type of nonionic surfactant. For example,

triethanol amine derived ester quaternary amines suitable for use as softener actives according to the present invention are typically manufactured in such a way as to yield a distribution of mono-, di-, and tri-esterified quaternary ammonium compounds and amine precursors. Therefore, as in this example, the variability in the distribution of mono-, di-, and tri-esters and amines may predicate a different level of electrolyte. Therefore, the formulator must consider all of the ingredients, namely, softener active, nonionic surfactant, and in the case of isotropic liquids, the principal solvent type and level, as well as level and identity of adjunct ingredients before selecting the type and/or level of electrolyte A wide variety of ionizable salts can be used. Examples of suitable salts are the halides of the Group IA and HA metals of the Periodic Table of the elements, e. g., calcium chloride, sodium chloride, potassium bromide, and lithium chloride. The ionizable salts are particularly useful during the process of mixing the ingredients to make the compositions herein, and later to obtain the desired viscosity. The amount of ionizable salts used depends on the amount of active ingredients used in the compositions and can be adjusted according to the desires of the formulator. Typical levels of salts used to control the composition viscosity are from about 20 to about 10,000 parts per million (ppm), preferably from about 20 to about 5,000 ppm, of the composition.

Alkylene polyammonium salts can be incorporated into the composition to give viscosity control in addition to or in place of the water-soluble, ionizable salts above, In addition, these agents can act as scavengers, forming ion pairs with anionic detergent carried over from the main wash, in the rinse, and on the fabrics, and can improve softness performance. These agents can stabilized the viscosity over a broader range of temperature, especially at low temperatures, compared to the inorganic electrolytes. Specific examples of alkylene polyammonium salts include L-lysine, monohydrochloride and 1,5-diammonium 2-methyl pentane dihydrochloride.

Cationic Charge Booster Svstem The compositions of the present invention may optionally comprise from about 0.2%, preferably from about 5% to about 10%, preferably to about 7% by weight, of a charge booster system. Typically, ethanol is used to prepare many of the below listed ingredients and is therefore a source of solvent into the final product formulation. The formulator is not limited to ethanol, but instead can add other solvents inter alia hexyleneglycol to aid in formulation of the final composition. This is especially true in clear, translucent, isotropic compositions.

Monometallic, mononuclear complexes are preferred. As defined herein, a monometallic transition-metal bleach catalyst contains only one transition metal atom per mole of complex. A monometallic, mononuclear complex is one in which any donor atoms of the essential macrocyclic ligand are bonded to the same transition metal atom, that is, the essential ligand does not"bridge"across two or more transition-metal atoms.

Builders The laundry detergent compositions of the present invention preferably comprise one or more detergent builders or builder systems. When present, the compositions will typically comprise at least about 1% builder, preferably from about 5%, more preferably from about 10% to about 80%, preferably to about 50%, more preferably to about 30% by weight, of detergent builder.

The level of builder can vary widely depending upon the end use of the composition and its desired physical form. When present, the compositions will typically comprise at least about 1% builder. Formulations typically comprise from about 5% to about 50%, more typically about 5% to about 30%, by weight, of detergent builder. Granular formulations typically comprise from about 10% to about 80%, more typically from about 15% to about 50% by weight, of the detergent builder. Lower or higher levels of builder, however, are not meant to be excluded.

Inorganic or P-containing detergent builders include, but are not limited to, the alkali metal, ammonium and alkanolammonium salts of polyphosphates (exemplified by the tripolyphosphates, pyrophosphates, and glassy polymeric meta-phosphates), phosphonates, phytic acid, silicates, carbonates (including bicarbonates and sesquicarbonates), sulphates, and aluminosilicates. However, non-phosphate builders are required in some locales. Importantly, the compositions herein function surprisingly well even in the presence of the so-called"weak" builders (as compared with phosphates) such as citrate, or in the so-called"underbuilt"situation that may occur with zeolite or layered silicate builders.

Examples of silicate builders are the alkali metal silicates, particularly those having a Si02 : Na2O ratio in the range 1.6: 1 to 3.2: 1 and layered silicates, such as the layered sodium silicates described in U. S. 4,664,839 Rieck, issued May 12,1987. NaSKS-6 is the trademark for a crystalline layered silicate marketed by Hoechst (commonly abbreviated herein as"SKS-6").

Unlike zeolite builders, the Na SKS-6 silicate builder does not contain aluminum. NaSKS-6 has the delta-Na2SiO5 morphology form of layered silicate. It can be prepared by methods such as those described in German DE-A-3,417,649 and DE-A-3,742,043. SKS-6 is a highly preferred layered silicate for use herein, but other such layered silicates, such as those having the general formula NaMSixO2x+l yH2O wherein M is sodium or hydrogen, x is a number from 1.9 to 4, preferably 2, and y is a number from 0 to 20, preferably 0 can be used herein. Various other layered silicates from Hoechst include NaSKS-5, NaSKS-7 and NaSKS-11, as the alpha, beta and gamma forms. As noted above, the delta-Na2SiO5 (NaSKS-6 form) is most preferred for use herein. Other silicates may also be useful such as for example magnesium silicate, which can serve as a crispening agent in granular formulations, as a stabilizing agent for oxygen bleaches, and as a component of suds control systems.

Examples of carbonate builders are the alkaline earth and alkali metal carbonates as disclosed in German Patent Application No. 2,321,001 published on November 15,1973.

Aluminosilicate builders are useful in the present invention. Aluminosilicate builders are of great importance in most currently marketed heavy duty granular detergent compositions, and can also be a significant builder ingredient in liquid detergent formulations. Aluminosilicate builders include those having the empirical formula: Mz (zAlo2) y'XH2° wherein z and y are integers of at least 6, the molar ratio of z to y is in the range from 1.0 to about 0.5, and x is an integer from about 15 to about 264.

Useful aluminosilicate ion exchange materials are commercially available. These aluminosilicates can be crystalline or amorphous in structure and can be naturally-occurring

aluminosilicates or synthetically derived. A method for producing aluminosilicate ion exchange materials is disclosed in U. S. 3,985,669, Krummel et al, issued October 12,1976. Preferred synthetic crystalline aluminosilicate ion exchange materials useful herein are available under the designations Zeolite A, Zeolite P (B), Zeolite MAP and Zeolite X. In an especially preferred embodiment, the crystalline aluminosilicate ion exchange material has the formula: Nai2 (A102) i2 (Si02) i2-xH20 wherein x is from about 20 to about 30, especially about 27. This material is known as Zeolite A. Dehydrated zeolites (x = 0-10) may also be used herein. Preferably, the aluminosilicate has a particle size of about 0.1-10 microns in diameter.

Organic detergent builders suitable for the purposes of the present invention include, but are not restricted to, a wide variety of polycarboxylate compounds. As used herein,"poly- carboxylate"refers to compounds having a plurality of carboxylate groups, preferably at least 3 carboxylates. Polycarboxylate builder can generally be added to the composition in acid form, but can also be added in the form of a neutralized salt. When utilized in salt form, alkali metals, such as sodium, potassium, and lithium, or alkanolammonium salts are preferred.

Included among the polycarboxylate builders are a variety of categories of useful mate- rials. One important category of polycarboxylate builders encompasses the ether polycarboxy- lates, including oxydisuccinate, as disclosed in U. S. 3,128,287 Berg, issued April 7,1964, and U. S. 3,635,830 Lamberti et al., issued January 18,1972. See also"TMS/TDS"builders of U. S.

4,663,071 Bush et al., issued May 5,1987. Suitable ether polycarboxylates also include cyclic compounds, particularly alicyclic compounds, such as those described in U. S. 3,923,679 Rapko, issued December 2,1975; U. S. 4,158,635 Crutchfield et al., issued June 19,1979; U. S.

4,120,874 Crutchfield et al., issued October 17,1978; and U. S. 4,102,903 Crutchfield et al., issued July 25,1978.

Other useful detergency builders include the ether hydroxypolycarboxylates, copolymers of maleic anhydride with ethylene or vinyl methyl ether, 1,3,5-trihydroxy benzene-2,4,6- trisulphonic acid, and carboxymethyloxysuccinic acid, the various alkali metal, ammonium and substituted ammonium salts of polyacetic acids such as ethylenediamine tetraacetic acid and nitrilotriacetic acid, as well as polycarboxylates such as mellitic acid, succinic acid, oxy- disuccinic acid, polymaleic acid, benzene 1,3,5-tricarboxylic acid, carboxymethyloxysuccinic acid, and soluble salts thereof.

Citrate builders, e. g., citric acid and soluble salts thereof (particularly sodium salt), are polycarboxylate builders of particular importance for heavy duty liquid detergent formulations due to their availability from renewable resources and their biodegradability. Citrates can also

be used in granular compositions, especially in combination with zeolite and/or layered silicate builders. Oxydisuccinates are also especially useful in such compositions and combinations.

Also suitable in the detergent compositions of the present invention are the 3,3-dicar- boxy-4-oxa-1,6-hexanedioates and the related compounds disclosed in U. S. 4,566,984, Bush, issued January 28,1986. Useful succinic acid builders include the Cs-C20 alkyl and alkenyl succinic acids and salts thereof. A particularly preferred compound of this type is do- decenylsuccinic acid. Specific examples of succinate builders include: laurylsuccinate, myristylsuccinate, palmitylsuccinate, 2-dodecenylsuccinate (preferred), 2-pentadecenylsuccinate, and the like. Laurylsuccinates are the preferred builders of this group, and are described in European Patent Application 86200690.5/0,200,263, published November 5,1986.

Other suitable polycarboxylates are disclosed in U. S. 4,144,226, Crutchfield et al., issued March 13,1979 and in U. S. 3,308,067, Diehl, issued March 7,1967. See also Diehl U. S. Patent 3,723,322.

Fatty acids, e. g., C 12-C 1 g monocarboxylic acids, can also be incorporated into the compositions alone, or in combination with the aforesaid builders, especially citrate and/or the succinate builders, to provide additional builder activity. Such use of fatty acids will generally result in a diminution of sudsing, which should be taken into account by the formulator.

In situations where phosphorus-based builders can be used, and especially in the for- mulation of bars used for hand-laundering operations, the various alkali metal phosphates such as the well-known sodium tripolyphosphates, sodium pyrophosphate and sodium orthophosphate can be used. Phosphonate builders such as ethane-1-hydroxy-1,1-diphosphonate and other known phosphonates (see, for example, U. S. Patents 3,159,581; 3,213,030; 3,422,021; 3,400,148 and 3,422,137) can also be used.

Dispersants A description of other suitable polyalkyleneimine dispersants which may be optionally combined with the bleach stable dispersants of the present invention can be found in U. S.

4,597,898 Vander Meer, issued July 1,1986; European Patent Application 111,965 Oh and Gosselink, published June 27,1984; European Patent Application 111,984 Gosselink, published June 27,1984; European Patent Application 112,592 Gosselink, published July 4,1984; U. S.

4,548,744 Connor, issued October 22,1985; and U. S. 5,565,145 Watson et al., issued October 15, 1996; all of which are included herein by reference. However, any suitable clay/soil dispersant or anti-redepostion agent can be used in the laundry compositions of the present invention.

In addition, polymeric dispersing agents which include polymeric polycarboxylates and polyethylene glycols, are suitable for use in the present invention. Polymeric polycarboxylate

materials can be prepared by polymerizing or copolymerizing suitable unsaturated monomers, preferably in their acid form. Unsaturated monomeric acids that can be polymerized to form suitable polymeric polycarboxylates include acrylic acid, maleic acid (or maleic anhydride), fumaric acid, itaconic acid, aconitic acid, mesaconic acid, citraconic acid and methylenemalonic acid. The presence in the polymeric polycarboxylates herein or monomeric segments, containing no carboxylate radicals such as vinylmethyl ether, styrene, ethylene, etc. is suitable provided that such segments do not constitute more than about 40% by weight.

Particularly suitable polymeric polycarboxylates can be derived from acrylic acid. Such acrylic acid-based polymers which are useful herein are the water-soluble salts of polymerized acrylic acid. The average molecular weight of such polymers in the acid form preferably ranges from about 2,000 to 10,000, more preferably from about 4,000 to 7,000 and most preferably from about 4,000 to 5,000. Water-soluble salts of such acrylic acid polymers can include, for example, the alkali metal, ammonium and substituted ammonium salts. Soluble polymers of this type are known materials. Use of polyacrylates of this type in detergent compositions has been disclosed, for example, in Diehl, U. S. Patent 3,308,067, issued march 7,1967.

Acrylic/maleic-based copolymers may also be used as a preferred component of the dispersing/anti-redeposition agent. Such materials include the water-soluble salts of copolymers of acrylic acid and maleic acid. The average molecular weight of such copolymers in the acid form preferably ranges from about 2,000, preferably from about 5,000, more preferably from about 7,000 to 100,000, more preferably to 75,000, most preferably to 65,000. The ratio of acrylate to maleate segments in such copolymers will generally range from about 30: 1 to about 1: 1, more preferably from about 10: 1 to 2: 1. Water-soluble salts of such acrylic acid/maleic acid copolymers can include, for example, the alkali metal, ammonium and substituted ammonium salts. Soluble acrylate/maleate copolymers of this type are known materials which are described in European Patent Application No. 66915, published December 15,1982, as well as in EP 193,360, published September 3,1986, which also describes such polymers comprising hydroxypropylacrylate. Still other useful dispersing agents include the maleic/acrylic/vinyl alcohol terpolymers. Such materials are also disclosed in EP 193,360, including, for example, the 45/45/10 terpolymer of acrylic/maleic/vinyl alcohol.

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 range 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.

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.

Soil Release Agents The compositions according to the present invention may optionally comprise one or more soil release agents. If utilized, soil release agents will generally comprise from about 0.01%, preferably from about 0.1%, more preferably from about 0.2% to about 10%, preferably to about 5%, more preferably to about 3% by weight, of the composition. Polymeric soil release agents are characterized by having both hydrophilic segments, to hydrophilize the surface of hydrophobic fibers, such as polyester and nylon, and hydrophobic segments, to deposit upon hydrophobic fibers and remain adhered thereto through completion of the laundry cycle and, thus, serve as an anchor for the hydrophilic segments. This can enable stains occuring subsequent to treatment with the soil release agent to be more easily cleaned in later washing procedures.

METHOD OF DELIVERY

The compositions of the present invention need not be delivered via the laundry liquor or during the rinse cycle. For example, the embodiments of the present invention can be delivered directly to fabric either after drying, while still wet, or before the fabric is laundered. Thus the fabric treatment compositions of the present invention can be delivered to the situs of required treatment by any method suitable to the formulator.

One means for delivering the fabric care compositions, especially to areas wherein the composition will be allowed to remain on the surface of fabric, is via aerosol mousse discharged as an expandable and subsequently collapsible foam. For example, the composition is applied to an article of clothing having a porous surface (i. e., cotton) as a foam which expands to fill the interstices of the surface, remains as a foam until the composition is evenly delivered, and then collapses, after a period of time, signaling to the consumer that the composition has been effectively applied.

Non-limiting examples of methods for delivering the compositions of the present invention include direct pump sprayers, aerosol sprays (using aqueous or non-aqueous based propellants), by soft-tipped applicator, or by an applicator which comprises an abrasive element to aid in breaking up any dirt or other surface residue and delivering the composition directly to the surface.

The detergent compositions according to the present invention can be in liquid, paste, laundry bar, or granular form. Such compositions can be prepared by combining the essential and optional components in the requisite concentrations in any suitable order and by any conventional means.

The polyalkyleneimines of the present invention can be incorporated into granular detergent compositions in a variety of ways inter alia they can be suitably added as a slurry followed by spray drying of the slurry, the dispersants can be added as a separate particle, sprayed on to a nearly finished product, added with the balance of adjunct ingredients.

As a non-limiting example, granular compositions are generally made by combining base granule ingredients, e. g., surfactants, builders, water, etc., as a slurry, and spray drying the resulting slurry to a low level of residual moisture (5-12%). The remaining dry ingredients, e. g., granules of the polyalkyleneimine dispersant, can be admixed in granular powder form with the spray dried granules in a rotary mixing drum. The liquid ingredients, e. g., solutions of the polyalkyleneimine dispersant, enzymes, binders and perfumes, can be sprayed onto the resulting granules to form the finished detergent composition. Granular compositions according to the present invention can also be in"compact form", i. e. they may have a relatively higher density

than conventional granular detergents, i. e. from 550 to 950 g/l. In such case, the granular detergent compositions according to the present invention will contain a lower amount of "inorganic filler salt", compared to conventional granular detergents; typical filler salts are alkaline earth metal salts of sulphates and chlorides, typically sodium sulphate;"compact" detergents typically comprise not more than 10% filler salt.

Liquid detergent compositions can be prepared by admixing the essential and optional ingredients thereof in any desired order to provide compositions containing components in the requisite concentrations. Liquid compositions according to the present invention can also be in "compact form", in such case, the liquid detergent compositions according to the present invention will contain a lower amount of water, compared to conventional liquid detergents.

Addition of the polyalkyleneimine dispersant to liquid detergent or other aqueous compositions of this invention may be accomplished by simply mixing into the liquid solutions the polyalkyleneimine dispersant.

The compositions of the present invention can be suitably prepared by any process chosen by the formulator, non-limiting examples of which are described in U. S. 5,691,297 Nassano et al., issued November 11,1997; U. S. 5,574,005 Welch et al., issued November 12, 1996; U. S. 5,569,645 Dinniwell et al., issued October 29,1996; U.
