Co-polymeric compounds comprising one or more active aldehyde monomeric unit Field of the invention The present invention relates to co-polymeric compounds comprising one or more active aldehyde monomeric unit. More particularly, it relates to polymeric compounds of aldehyde active monomeric unit and glyoxylic monomeric unit for use in laundry and cleaning products as well as personal care compositions.

Background of the invention <BR> <BR> Cleaning and laundry products are well-known in the art. However, z, sumer acceptance of laundry and cleaning products is determined not only by the performance achieved with these products but also the aesthetics associated therewith. The perfume components are therefore an important aspect of the successful formulation of such commercial products.

It is also desired by consumers for laundered fabrics to maintain the leasing fragrance over time. Indeed, perfume additives make laundry compositions more aesthetically leasing to the consumer, and in some cases the perfume imparts a pleasant fragrance to fabrics treated therewith. However, the amount of perfume

carry-over from an aqueous laundry bath onto fabrics is often marginal and does not last long on the fabric. Furthermore, fragrance materials are often very costly and their inefficient use in laundry and cleaning compositions and ineffective delivery to fabrics result in a very high cost to both consumers and laundry and cleaning manufacturers. Industry, therefore, continues to seek with urgency for more efficient and effective fragrance delivery in laundry and cleaning products, especially for improvement in the provision of long-lasting fragrance to the fabrics.

One solution is to use carrier mechanisms for perfume delivery, such as by encapsulation. This is taught in the prior art and described in U. S. 5,188,753.

Still another solution is to formulate compounds which provide a delayed release of the perfume over a longer period of time than by the use of the perfume itself have been provided. Disclosure of such compounds may be found in WO 95/04809, WO 95/08976 and pending application EP 95303762.9.

However, notwithstanding the advances in the art, there is still a need for a compound which provides a delayed release of the perfume component.

The Applicant has now found that co-polymeric compounds comprising one or more active aldehyde ingredient also provide a delayed release of the active such as a perfume.

Another advantage of the invention is that it allows the incorporation of a high proportion of active aldehyde into a polymeric compound. Preparing a polymer of an active aldehyde alone would be highly desirable for the controlled release of said active aldehyde. However, it is known to the persons skilled in the art that these poly (active aldehyde) can not be easily obtained by direct polymerisation of one or more active aldehydes alone. The applicants have found that the polymerisation of a suitable comonomer along with the active aldehydes allow them to incorporate a high proportion of one or more active aldehydes into a polymeric compound. Had the co-monomer not been present, no incorporation of the aldehyde into a polymeric compound would have taken place, under the same conditions.

Still another advantage of the present invention is that by choosing the suitable co-monomeric unit and end-capping groups, it provides sufficient stabilisation of the linkage bond between the active aldehyde group with its polymeric carrier so that the release of the active ingredients upon storage in product is limite, without hindering the release of the active ingredients upon use of the product.

Still another advantage of the invention compounds is their ease of manufacture rendering their use most desirable.

Summary of the invention The present invention relates to a co-polymeric compound comprising one or more active aldehyde ingredient, wherein said compound has the following empirical formula: ~ [Ym An] ~ wherein Y is a comonomeric aldehyde unit of formula R'COH, wherein R'is the organic chain of an active aldehyde, wherein A is a comonomeric unit capable of polymerising the aldehyde monomeric unit, and wherein n and m are each independently indexes of value of at least 1.

In another aspect of the invention, there is provided a laundry and cleaning composition or personal cleansing composition comprising said compound.

Still another aspect of the invention is a method of delivering residual fragrance to a surface which comprises the steps of contacting said surface with a compound of the invention or a composition comprising said compound in presence of a material so that the copolymer backbone is hydrolysed, thereby slowly releasing overtime the perfume aldehydes.

The essential component of the invention is a co-polymeric compound comprising one or more active aldehyde ingredient.

For the purpose of the invention, mixtures of the above compounds comprising one or more active aldehydes may also be used.

Mechanism of release By the present invention, a delayed release of an active ingredient, i. e. aldehyde is obtained. Not to be bound by theory, the release is believed to occur by the followingmechanism: For copolymers or oligomers of active aldehydes and of suitable comonomers such as keto carboxylates (in particular glyoxylic esters), the active aldehydes are released upon breaking down of the acetals bond forming the backbone of the polymer, leading to the release of the active aldehyde and of the suitable

comonomers. This can be achieved by either hydrolysis, photochemical cleavage, enzymatic cleavage or oxidative cleavage of the bond linking the end- capping group to the rest of the polymer or any acetal bonds along the polymer backbone.

Process Preparation of the component is made as follows in the Synthesis Examples. In general, process for preparing a copolymer comprising one or more active aldehydes comprises the steps of polymerising one or more active aldehydes with one or more suitable comonomers, preferably keto carboxylates, most preferably glyoxylates such as methyl glyoxylate, in presence of a polymerisation catalyst, preferably a strong Lewis acid such as boron trifluoride diethyl etherate or an anionic catalyst such as sodiomalonates or sodiomethylmalonate esters.

Preferred features of these general processes for manufacturing the present compounds invention are described hereinafter.

A preferred process for preparing copolymers of one or more active aldehydes: (A)-to bring together under polymerisation conditions one or more active aldehydes with one or more comonomers capable of polymerising the aldehyde monomeric unit, in presence of a polymerisation initiator; and (B)-End-capping the resulting copolymer with a suitable chemical group so that the in-product stability of the polymer can be optimised to prevent excessive depolymerisation in-product.

As described hereinbefore, the preferred comonomers capable of polymerising the aldehyde monomeric unit are the a-keto carboxylates, most preferably the methyl glyoxylate.

Suitable initiator for the copolymerisation are know to those skilled in the art and described in the art such as in US 4,204,052 Column 4, lines 3-15. Preferred initiators are phosphorus pentoxide, amines, strong Lewis acid such as boron trifluoride diethyl etherate, hydroxide or cyanide ions or anionic catalyst such as sodiomalonates or sodiomethylmalonate esters. Most preferred initiators are phosphorus pentoxide, amines, strong Lewis acid such as boron trifluoride

diethyl etherate, or anionic catalyst such as sodiomalonates or sodiomethylmalonate esters.

The copolymerisation step can be done with or without solvent. Suitable solvents include alkyl nitriles, preferably acetonitrile, dimethyl sulfoxide, acetone, halogenated alkanes, preferably dichloromethane or chloroform, tetrahydrofuran, ethyl acetate and the like. When a solvent is used, the choice of the solvent is driven, so that it does not interfere with the copolymerisation and can be separated from the resulting copolymer with relative ease. These solvents can also be used for the end-capping step (B). Dichloromethane and acetonitrile are the preferred solvents for both steps (A) and (B) of the process.

Once the copolymer of one or more active aldehydes and at least one suitable comonomer has been prepared, any number of chemically reactive groups can be added to the copolymer termini, preferably using an ionic catalyst such as boron trifluoride etherate, trifluoroacetic acid and the like as described in US 4,204,052 Column 5 line 25 to Column 6 line 28.

The resulting co-polymer has the following empirical formula: R1-[Ym-An]-R2 wherein Y, A, m and n are as defined hereinbefore; and wherein R1 and R2 are end-capping groups.

Particularly suitable end-capping groups include alkyl groups, alkyl groups containing oxygen such as-CH2CHOH or alkoxy, preferably methoxy, or ethers such as-CH (CH3)-O-CH2CH3,-OCH2CHOH and-OCH (CH3)-O-CH2CH3, and alkyl groups containing carboxylic acids. Particularly preferred end-capping groups for the purpose of the invention are alkyl groups containing oxygen, preferably selected from-CH2CHOH,-CH (CH3)-O-CH2CH3,-OCH2CHOH and -OCH (CH3)-O-CH2CH3. As will occur to those skilled in the art in light of the present disclosure, the chemically stable end groups at the polymer termini can be like or unlike.

The chemical nature of the chemically reactive group is not important in the proper function of the copolymer in its intended use to release active aldehydes.

It is only necessary that the chemically reactive group stabilises the copolymer so

that to limit the depolymerisation before use. The end-capping group can be chosen so that depolymerisation upon usage is triggered by either hydrolysis, photochemical cleavage, enzymatic cleavage or oxidative cleavage of the bond linking the end-capping group to the rest of the polymer or any acetal bonds along the polymer backbone.

Both N, N"-ditallowalkoyldiethylenetriamine and 1-tallow (amidoethyl)-2- tallowimidazoline are reaction products of tallow fatty acids and diethylenetriamine, and are precursors of the cationic fabric softening agent methyl-1-tallowamidoethyl-2-tallowimidazolinium methylsulfate (see"Cationic Surface Active Agents as Fabric Softeners,"R. R. Egan, Journal of the American Oil Chemicals'Society, January 1978, pages 118-121). N, N"-ditallow alkoyldiethylenetriamine and 1-tallowamidoethyl-2-tallowimidazoline can be obtained from Witco Chemical Company as experimental chemicals.

Additional fabric softening materials may be used in addition or alternatively to the cationic fabric softener. These may be selected from nonionic, amphoteric or anionic fabric softening material. Disclosure of such materials may be found in US 4,327,133; US 4,421,792; US 4,426,299; US 4,460,485; US 3,644,203; US 4,661,269 ; U. S 4,439,335; U. S 3,861,870; US 4,308,151; US 3,886,075; US 4,233,164; US 4,401,578; US 3,974,076; US 4,237,016 and EP 472,178.

Typically, such nonionic fabric softener materials have an HLB of from 2 to 9, more typically from 3 to 7. Such nonionic fabric softener materials tend to be readily dispersed either by themselves, or when combined with other materials such as single-long-chain alkyl cationic surfactant described in detail hereinafter.

Dispersibility can be improved by using more single-long-chain alkyl cationic surfactant, mixture with other materials as set forth hereinafter, use of hotter water, and/or more agitation. In general, the materials selected should be relatively crystalline, higher melting, (e. g. >40°C) and relatively water-insoluble.

Preferred nonionic softeners are fatty acid partial esters of polyhydric alcools, or anhydrides thereof, wherein the alcool, or anhydride, contains from 2 to 18, preferably from 2 to 8, carbon atoms, and each fatty acid moiety contains from 12 to 30, preferably from 16 to 20, carbon atoms. Typically, such softeners contain from one to 3, preferably 2 fatty acid groups per molecule.

The polyhydric alcohol portion of the ester can be ethylene glycol, glycerol, poly (e. g., di-, tri-, tetra, penta-, and/or hexa-) glycerol, xylitol, sucrose, erythritol, pentaerythritol, sorbitol or sorbitan. Sorbitan esters and polyglycerol monostearate are particularly preferred.

The fatty acid portion of the ester is normally derived from fatty acids having from 12 to 30, preferably from 16 to 20, carbon atoms, typical examples of said fatty acids being lauric acid, myristic acid, palmitic acid, stearic acid and behenic acid.

Highly preferred optional nonionic softening agents for use in the present invention are the sorbitan esters, which are esterified dehydration products of sorbitol, and the glycerol esters.

Commercial sorbitan monostearate is a suitable material. Mixtures of sorbitan stearate and sorbitan palmitate having stearate/palmitate weight ratios varying between 10: 1 and 1: 10, and 1,5-sorbitan esters are also useful.

Glycerol and polyglycerol esters, especially glycerol, diglycerol, triglycerol, and polyglycerol mono-and/or di-esters, preferably mono-, are preferred herein (e. g. polyglycerol monostearate with a trade name of Radiasurf 7248).

Useful glycerol and polyglycerol esters include mono-esters with stearic, oleic, palmitic, lauric, isostearic, myristic, and/or behenic acids and the diesters of stearic, oleic, palmitic, lauric, isostearic, behenic, and/or myristic acids. It is understood that the typical mono-ester contains some di-and tri-ester, etc.

The"glycerol esters"also include the polyglycerol, e. g., diglycerol through octaglycerol esters. The polyglycerol polyols are formed by condensing glycerin or epichlorohydrin together to link the glycerol moieties via ether linkages. The mono-and/or diesters of the polyglycerol polyols are preferred, the fatty acyl groups typically being those described hereinbefore for the sorbitan and glycerol esters.

Further fabric softening components suitable for use herein are the softening clays, such as the low ion-exchange-capacity ones described in EP-A- 0,150,531.

Of course, the term"softening active"can also encompass mixed softening active agents.

This particular brightener species is commercially marketed under the tradename Tinopal AMS-GX (§) by Ciba Geigy Corporation.

(B) Dispersibility Aids Relatively concentrated compositions containing both saturated and unsaturated diester quaternary ammonium compounds can be prepared that are stable without the addition of concentration aids. However, the compositions of the present invention may require organic and/or inorganic concentration aids to go to even higher concentrations and/or to meet higher stability standards depending on the other ingredients. These concentration aids which typically can be viscosity modifiers may be needed, or preferred, for ensuring stability under extreme conditions when particular softener active levels are used. The surfactant concentration aids are typically selected from the group consisting of (1) single long chain alkyl cationic surfactants; (2) nonionic surfactants; (3) amine oxides; (4) fatty acids; and (5) mixtures thereof. These aids are described in WO 94/20597, specifically on page 14, line 12 to page 20, line 12, which is herein incorporated by reference.

When said dispersibility aids are present, the total level is from 2% to 25%, preferably from 3% to 17%, more preferably from 4% to 15%, and even more preferably from 5% to 13% by weight of the composition. These materials can either be added as part of the active softener raw material, (I), e. g., the mono- long chain alkyl cationic surfactant and/or the fatty acid which are reactants used to form the biodegradable fabric softener active as discussed hereinbefore, or added as a separate component. The total level of dispersibility aid includes any amount that may be present as part of component (I).

(1) Mono-Alkyl Cationic Quaternary Ammonium Compound When the mono-alkyl cationic quaternary ammonium compound is present, it is typically present at a level of from 2% to 25%, preferably from 3% to 17%, more

preferably from 4% to 15%, and even more preferably from 5% to 13% by weight of the composition, the total mono-alkyl cationic quaternary ammonium compound being at least at an effective level.

Such mono-alkyl cationic quaternary ammonium compounds useful in the present invention are, preferably, quaternary ammonium salts of the general formula: [R4N+ (R5) g] X- wherein R4 is Cg-C22 alkyl or alkenyl group, preferably C10-C1g alkyi or alkenyl group; more preferably Cio-Ci4 or Cg-Cg alkyl or alkenyl group; each R5 is a C1-C6 alkyl or substituted alkyl group (e. g., hydroxy alkyl), preferably C1-C3 alkyl group, e. g., methyl (most preferred), ethyl, propyl, and the like, a benzyl group, hydrogen, a polyethoxylated chain with from 2 to 20 oxyethylene units, preferably from 2.5 to 13 oxyethylene units, more preferably from 3 to 10 oxyethylene units, and mixtures thereof; and X-is as defined hereinbefore for (Formula (I)).

Especially preferred dispersibility aids are monolauryl trimethyl ammonium chloride and monotallow trimethyl ammonium chloride available from Witco under the trade names Adogen 412 and Adogen 471, monooleyl or monocanola trimethyl ammonium chloride available from Witco under the tradename Adogen @ 417, monococonut trimethyl ammonium chloride available from Witco under the trade name Adogen 461, and monosoya trimethyl ammonium chloride available from Witco under the trade name Adogen 415.

The R4 group can also be attached to the cationic nitrogen atom through a group containing one, or more, ester, amide, ether, amine, etc., linking groups which can be desirable for increased concentratability of component (I), etc. Such linking groups are preferably within from one to three carbon atoms of the nitrogen atom.

Mono-alkyl cationic quaternary ammonium compounds also include Cg-C22 alkyl choline esters. The preferred dispersibility aids of this type have the formula: R1 C (O)-O-CH2CH2N+ (R) 3 X- wherein R1, R and X-are as defined previously.

Highly preferred dispersibility aids include C12-C14 coco choline ester and C16- C18 tallow choline ester.

Suitable biodegradable single-long-chain alkyl dispersibility aids containing an ester linkage in the long chains are described in U. S. 4,840,738, said patent being incorporated herein by reference.

When the dispersibility aid comprises alkyl choline esters, preferably the compositions also contain a small amount, preferably from 2% to 5% by weight of the composition, of organic acid. Organic acids are described in EP. 404,471, which is herein incorporated by reference. Preferably the organic acid is selected from the group consisting of glycolic acid, acetic acid, citric acid, and mixtures thereof.

Ethoxylated quaternary ammonium compounds which can serve as the dispersibility aid include ethylbis (polyethoxy ethanol) alkylammonium ethyl-sulfate with 17 moles of ethylene oxide, available under the trade name Variquat 66 from Witco Corporation; polyethylene glycol (15) oleammonium chloride, available under the trade name Ethoquad 0/25 from Akzo; and polyethylene glycol (15) cocomonium chloride, available under the trade name Ethoquad C/25 from Akzo.

Quaternary compounds having only a single long alkyl chain, can protect the cationic softener from interacting with anionic surfactants and/or detergent builders that are carried over into the rinse from the wash solution.

(2) Nonionic Surfactant (Alkoxylated Materials) Suitable nonionic surfactants to serve as the viscosity/dispersibility modifier include addition products of ethylene oxide and, optionally, propylene oxide, with fatty alcools, fatty acids, fatty amines, etc. They are referred to herein as ethoxylated fatty alcohols, ethoxylated fatty acids, and ethoxylated fatty amines.

Any of the alkoxylated materials of the particular type described hereinafter can be used as the nonionic surfactant. In general terms, the nonionics herein, when used alone, in liquid compositions are at a level of from 0% to 5%, preferably from 0.1% to 5%, more preferably from 0.2% to 3%. Suitable compounds are substantially water-soluble surfactants of the general formula: R2-Y- (C2H40) z-C2H40H wherein R2 for both solid and liquid compositions is selected from the group consisting of primary, secondary and branched chain alkyl and/or acyl hydrocarbyl groups; primary, secondary and branched chain alkenyl hydrocarbyl groups; and primary, secondary and branched chain alkyl-and alkenyl-substituted phenolic hydrocarbyl groups; said hydrocarbyl groups having

a hydrocarbyl chain length of from 8 to 20, preferably from 10 to 18 carbon atoms. More preferably the hydrocarbyl chain length for liquid compositions is from 16 to 18 carbon atoms and for solid compositions from 10 to 14 carbon atoms. In the general formula for the ethoxylated nonionic surfactants herein, Y is typically-O-,-C (O) O-,-C (O) N (R)-, or-C (O) N (R) R-, preferably-O-, and in which R2, and R, when present, have the meanings given hereinbefore, and/or R can be hydrogen, and z is at least 8, preferably at least 10-11. Performance and, usually, stability of the softener composition decrease when fewer ethoxy- late groups are present.

The nonionic surfactants herein are characterized by an HLB (hydrophilic-lipophilic balance) of from 7 to 20, preferably from 8 to 15. Of course, by defining R2 and the number of ethoxylate groups, the HLB of the surfactant is, in general, determined. However, it is to be noted that the nonionic ethoxylated surfactants useful herein, for concentrated liquid compositions, contain relatively long chain R2 groups and are relatively highly ethoxylated.

While shorter alkyl chain surfactants having short ethoxylated groups can possess the requisite HLB, they are not as effective herein.

Nonionic surfactants as the viscosity/dispersibility modifiers are preferred over the other modifiers disclosed herein for compositions with higher levels of perfume.

Examples of nonionic surfactants follow. The nonionic surfactants of this invention are not limited to these examples. In the examples, the integer defines the number of ethoxy (EO) groups in the molecule.

(3) Amine Oxides Suitable amine oxides include those with one alkyl or hydroxyalkyl moiety of 8 to 22 carbon atoms, preferably from 10 to 18 carbon atoms, more preferably from 8 to 14 carbon atoms, and two alkyl moieties selected from the group consisting of alkyl groups and hydroxyalkyl groups with 1 to 3 carbon atoms.

Examples include dimethyloctylamine oxide, diethyldecylamine oxide, bis- (2- hydroxyethyl) dodecyl-amine oxide, dimethyldodecylamine oxide, dipropyl- tetradecylamine oxide, methylethylhexadecylamine oxide, dimethyl-2- hydroxyoctadecylamine oxide, and coconut fatty alkyl dimethylamine oxide.

(C) Stabilizers

Stabilizers can be present in the compositions of the present invention. The term "stabilizer,"as used herein, includes antioxidants and reductive agents. These agents are present at a level of from 0% to 2%, preferably from 0.01% to 0.2%, more preferably from 0.035% to 0.1% for antioxidants, and more preferably from 0.01% to 0.2% for reductive agents. These assure good odor stability under long term storage conditions. Antioxidants and reductive agent stabilizers are especially critical for unscented or low scent products (no or low perfume).

Examples of antioxidants that can be added to the compositions of this invention include a mixture of ascorbic acid, ascorbic palmitate, propyl gallate, available from Eastman Chemical Products, Inc., under the trade names Tenox PG and Tenox S-1; a mixture of BHT (butylated hydroxytoluene), BHA (butylated hydroxyanisole), propyl galate, and citric acid, available from Eastman Chemical Products, Inc., under the trade name Tenox (E)-6; butylated hydroxytoluene, avail- able from UOP Process Division under the trade name Sustane BHT ; tertiary butylhydroquinone, Eastman Chemical Products, Inc., as Tenox (ÉD TBHQ tocopherols, Eastman Chemical Products, Inc., as Tenox# GT-1/GT-2 ; and butylated hydroxyanisole, Eastman Chemical Products, Inc., as BHA; long chain esters (C8-C22) of gallic acid, e. g., dodecyl gallate ; Irganox (E) 1010; lrganox# 1035; lrganox (D B 1171; Irganox 1425 ; Irganox 3114; Irganox 3125; and mixtures thereof; preferably Irganox 3125, Irganox 1425, Irganox 3114, and mixtures thereof; more preferably! rganox@ 3125 atone or mixed with citric acid and/or other chelators such as isopropyl citrate, Dequest 2010, available from Monsanto with a chemical name of 1-hydroxyethylidene-1,1-diphosphonic acid (etidronic acid), and TironO, available from Kodak with a chemical name of 4,5- dihydroxy-m-benzene-sulfonic acid/sodium salt, and DTPAO, available from Aldrich with a chemical name of diethylenetriaminepentaacetic acid.

(D) Soil Release Agent In the present invention, an optional soil release agent can be added. The addition of the soil release agent can occur in combination with the premix, in combination with the acid/water seat, before or after electrolyte addition, or after the final composition is made. The softening composition prepared by the process of the present invention herein can contain from 0% to 10%, preferably from 0.2% to 5%, of a soil release agent. Preferably, such a soil release agent is a polymer. Polymeric soil release agents useful in the present invention include

copolymeric blocks of terephthalate and polyethylene oxide or polypropylene oxide, and the like.

A preferred soil release agent is a copolymer having blocks of terephthalate and polyethylene oxide. More specifically, these polymers are comprised of repeating units of ethylene terephthalate and polyethylene oxide terephthalate at a molar ratio of ethylene terephthalate units to polyethylene oxide terephthalate units of from 25: 75 to 35: 65, said polyethylene oxide terephthalate containing polyethylene oxide blocks having molecular weights of from 300 to 2000. The molecular weight of this polymeric soil release agent is in the range of from 5,000 to 55,000.

Another preferred polymeric soil release agent is a crystallizable polyester with repeat units of ethylene terephthalate units containing from 10% to 15% by weight of ethylene terephthalate units together with from 10% to 50% by weight of polyoxyethylene terephthalate units, derived from a polyoxyethylene glycol of average molecular weight of from 300 to 6,000, and the molar ratio of ethylene terephthalate units to polyoxyethylene terephthalate units in the crystallizable polymeric compound is between 2: 1 and 6: 1. Examples of this polymer include the commercially available materials Zelcon 4780 (from Dupont) and Milease T 0 (from ICI).

Highly preferred soil release aqents are aolvmers of the aeneric formula: in which each X can be a suitable capping group, with each X typically being selected from the group consisting of H, and alkyl or acyl groups containing from 1 to 4 carbon atoms. p is selected for water solubility and generally is from 6 to 113, preferably from 20 to 50. u is critical to formulation in a liquid composition having a relatively high ionic strength. There should be very little material in which u is greater than 10. Furthermore, there should be at least 20%, preferably at least 40%, of material in which u ranges from 3 to 5.

The R14 moieties are essentially 1,4-phenylene moieties. As used herein, the term"the R14 moieties are essentially 1,4-phenylene moieties"refers to compounds where the R14 moieties consist entirely of 1,4-phenylene moieties, or are partially substituted with other arylene or alkarylene moieties, alkylene moieties, alkenylene moieties, or mixtures thereof. Arylene and alkarylene moieties which can be partially substituted for 1,4-phenylene include 1,3- phenylene, 1,2-phenylene, 1,8-naphthylene, 1,4-naphthylene, 2,2-biphenylene,

4,4-biphenylene, and mixtures thereof. Alkylene and alkenylene moieties which can be partially substituted include 1,2-propylene,-1, 4-butylene, 1,5-pentylene, 1,6-hexamethylene, 1,7-heptamethylene, 1,8-octamethylene, 1,4-cyclohexylene, and mixtures thereof.

For the R14 moieties, the degree of partial substitution with moieties other than 1,4-phenylene should be such that the soil release properties of the compound are not adversely affected to any great extent. Generally the degree of partial substitution which can be tolerated will depend upon the backbone length of the compound, i. e., longer backbones can have greater partial substitution for 1,4- phenylene moieties. Usually, compounds where the R14 comprise from 50% to 100% 1,4-phenylene moieties (from 0% to 50% moieties other than 1,4- phenylene) have adequate soil release activity. For example, polyesters made according to the present invention with a 40 : 60 mole ratio of isophthalic (1,3- phenylene) to terephthalic (1,4-phenylene) acid have adequate soil release activity. However, because most polyesters used in fiber making comprise ethylene terephthalate units, it is usually desirable to minimize the degree of partial substitution with moieties other than 1,4-phenylene for best soil release activity. Preferably, the R14 moieties consist entirely of (i. e., comprise 100%) 1,4-phenylene moieties, i. e., each R14 moiety is 1,4-phenylene.

For the R15 moieties, suitable ethylene or substituted ethylene moieties include ethylene, 1,2-propylene, 1,2-butylene, 1,2-hexylene, 3-methoxy-1,2-propylene, and mixtures thereof. Preferably, the R15 moieties are essentially ethylene moieties, 1,2-propylene moieties, or mixtures thereof. Inclusion of a greater percentage of ethylene moieties tends to improve the soil release activity of compounds. Surprisingly, inclusion of a greater percentage of 1,2-propylene moieties tends to improve the water solubility of compounds.

Therefore, the use of 1,2-propylene moieties or a similar branched equivalent is desirable for incorporation of any substantial part of the soil release component in the liquid fabric softener compositions. Preferably, from 75% to 100%, are 1,2- propylene moieties.

The value for each p is at least 6, and preferably is at least 10. The value for each n usually ranges from 12 to 113. Typically the value for each p is in the range of from 12 to 43.

A more complete disclosure of soil release agents is contained in U. S. Pat. Nos.: 4,661,267; 4,711,730; 4,749,596; 4,818,569; 4,877,896; 4,956,447 ; and 4,976,879, all of said patents being incorporated herein by reference.

These soil release agents can also act as scum dispersants.

(E) Scum Dispersant In the present invention, the premix can be combined with an optional scum dispersant, other than the soil release agent, and heated to a temperature at or above the melting point (s) of the components. _ The preferred scum dispersants herein are formed by highly ethoxylating hydrophobic materials. The hydrophobic material can be a fatty alcool, fatty acid, fatty amine, fatty acid amide, amine oxide, quaternary ammonium compound, or the hydrophobic moieties used to form soil release polymers. The preferred scum dispersants are highly ethoxylated, e. g., more than 17, preferably more than 25, more preferably more than 40, moles of ethylene oxide per molecule on the average, with the polyethylene oxide portion being from 76% to 97%, preferably from 81 % to 94%, of the total molecular weight.

The level of scum dispersant is sufficient to keep the scum at an acceptable, preferably unnoticeable to the consumer, level under the conditions of use, but not enough to adversely affect softening. For some purposes it is desirable that the scum is nonexistent. Depending on the amount of anionic or nonionic detergent, etc., used in the wash cycle of a typical laundering process, the efficiency of the rinsing steps prior to the introduction of the compositions herein, and the water hardness, the amount of anionic or nonionic detergent surfactant and detergency builder (especially phosphates and zeolites) entrapped in the fabric (laundry) will vary. Normally, the minimum amount of scum dispersant should be used to avoid adversely affecting softening properties. Typically scum dispersion requires at least 2%, preferably at least 4% (at least 6% and preferably at least 10% for maximum scum avoidance) based upon the level of softener active. However, at levels of 10% (relative to the softener material) or more, one risks loss of softening efficacy of the product especially when the fabrics contain high proportions of nonionic surfactant which has been absorbed during the washing operation.

Preferred scum dispersants are: Brij 700@; Varonic U-250@; Genapol T-500, Genapol T-800 ; Plurafac A-79 ; and Neodol 25-50.

(F) Bactericides Examples of bactericides used in the compositions of this invention include glutaraldehyde, formaldehyde, 2-bromo-2-nitro-propane-1,3-diol sold by Inolex

Chemicals, located in Philadelphia, Pennsylvania, under the trade name BronopolO, and a mixture of 5-chloro-2-methyl-4-isothiazoline-3-one and 2- methyl-4-isothiazoline-3-one sold by Rohm and Haas Company under the trade name Kathon 1 to 1,000 ppm by weight of the agent.

The perfumes useful in the present invention compositions are substantially free of halogenated materials and nitromusks.

Suitable solvents, diluents or carriers for perfumes ingredients mentioned above are for examples, ethanol, isopropanol, diethylene glycol, monoethyl ether, dipropylene glycol, diethyl phthalate, triethyl citrate, etc. The amount of such solvents, diluents or carriers incorporated in the perfumes is preferably kept to the minimum needed to provide a homogeneous perfume solution.

Perfume can be present at a level of from 0% to 10%, preferably from 0.1% to 5%, and more preferably from 0.2% to 3%, by weight of the finished composition.

Fabric softener compositions of the present invention provide improved fabric perfume deposition.

(H) Chelating Agents The compositions and processes herein can optionally employ one or more copper and/or nickel chelating agents ("chelators"). Such water-soluble chelating agents can be selected from the group consisting of amino carboxylates, amino phosphonates, polyfunctionally-substituted aromatic chelating agents and mixtures thereof, all as hereinafter defined. The whiteness and/or brightness of fabrics are substantially improved or restored by such chelating agents and the stability of the materials in the compositions are improved.

Amino carboxylates useful as chelating agents herein include ethylenedi- aminetetraacetates (EDTA), N-hydroxyethylethylenediaminetriacetates, nitrilotri- acetates (NTA), ethylenediamine tetraproprionates, ethylenediamine-N, N'- diglutamates, 2-hyroxypropylenediamine-N, N'-disuccinates, triethylenetetraaminehexacetates, diethylenetriaminepentaacetates (DETPA), and ethanoldiglycines, including their water-soluble salts such as the alkali metal, ammonium, and substituted ammonium salts thereof and mixtures thereof.

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), diethylenetriamine-N, N, N', N", N"-pentakis (methane phosphonate) (DETMP) and 1-hydroxyethane-1,1-diphosphonate (HEDP).

Preferably, these amino phosphonates to not contain alkyl or alkenyl groups with more than 6 carbon atoms.

The chelating agents are typically used in the present rinse process at levels from 2 ppm to 25 ppm, for periods from 1 minute up to several hours'soaking.

The preferred EDDS chelator used herein (also known as ethylenediamine-N, N'- disuccinate) is the material described in U. S. Patent 4,704,233.

As can be seen from the foregoing, a wide variety of chelators can be used herein. Indeed, simple polycarboxylates such as citrate, oxydisuccinate, and the like, can also be used, although such chelators are not as effective as the amino carboxylates and phosphonates, on a weight basis. Accordingly, usage levels may be adjusted to take into account differing degrees of chelating effectiveness.

The chelators herein will preferably have a stability constant (of the fully ionized chelator) for copper ions of at least 5, preferably at least 7. Typically, the chelators will comprise from 0.5% to 10%, more preferably from 0.75% to 5%, by weight of the compositions herein. Preferred chelators include DETMP, DETPA, NTA, EDDS and mixtures thereof.

(I)-Enzyme The compositions and processes herein can optionally employ one or more enzymes such as lipases, proteases, cellulase, amylases and peroxidases. A preferred enzyme for use herein is a cellulase enzyme. Indeed, this type of enzyme will further provide a color care benefit to the treated fabric. Cellulases usable herein include both bacterial and fungal types, preferably having a pH optimum between 5 and 9.5. U. S. 4,435,307 discloses suitable fungal cellulases from Humicola insolens or Humicola strain DSM1800 or a cellulase 212- producing fungus belonging to the genus Aeromonas, and cellulase extracted <BR> <BR> from the hepatopancreas of a marine mollusk, Dolabella Auricula Solander.

Suitable cellulases are also disclosed in GB-A-2.075.028; GB-A-2.095.275 and DE-OS-2.247.832. CAREZYME@ and CELLUZYME (Novo) are especially useful. Other suitable cellulases are also disclosed in WO 91/17243 to Novo, WO 96/34092, WO 96/34945 and EP-A-0,739,982. In practical terms for current commercial preparations, typical amounts are up to 5 mg by weight, more typically 0.01 mg to 3 mg, of active enzyme per gram of the detergent composition. Stated otherwise, the compositions herein will typically comprise from 0.001% to 5%, preferably 0.01%-1% by weight of a commercial enzyme preparation. In the particular cases where activity of the enzyme preparation can be defined otherwise such as with cellulases, corresponding activity units are preferred (e. g. CEVU or cellulase Equivalent Viscosity Units). For instance, the compositions of the present invention can contain cellulase enzymes at a level equivalent to an activity from 0.5 to 1000 CEVU/gram of composition. Cellulase

enzyme preparations used for the purpose of formulating compositions compositions this invention typically have an activity comprised between 1,000 and 10,000 CEVU/gram in liquid form, around 1,000 CEVU/gram in solid form.

(J) Liquid carrier Another optional, but preferred, ingredient is a liquid carrier. The liquid carrier employed in the instant compositions is preferably at least primarily water due to its low cost, relative availability, safety, and environmental compatibility. The level of water in the liquid carrier is preferably at least 50%, most preferably at least 60%, by weight of the carrier. Mixtures of water and low molecular weight, e. g., <200, organic solvent, e. g., lower alcools such as ethanol, propanol, isopropanol or butanol are useful as the carrier liquid. Low molecular weight alcohols include monohydric, dihydric (glycol, etc.) trihydric (glycerol, etc.), and higher polyhydric (polyols) alcohols.

(K) Other Optional Ingredients The present invention can include optional components conventionally used in textile treatment compositions, for example: colorants; preservatives; surfactants; anti-shrinkage agents; fabric crisping agents; spotting agents; germicides; fungicides; anti-oxidants such as butylated hydroxy toluene, anti-corrosion agents, and the like.

The present invention can also include other compatible ingredients, including those as disclosed in W096/02625, W096/21714, and W096/21715.

Various other optional adjunct ingredients may also be used to provide fully- formulated detergent compositions. The following ingredients are described for the convenience of the formulator, but are not intended to be limiting thereof.

Detersive Surfactants Non-limiting examples of surfactants useful herein typically at levels from 1% to 55%, by weight, include the conventional C11-C1g alkyl benzene sulfonates ("LAS") and primary, branched-chain and random C10-C20 alkyl sulfates ("AS"), the C10-C1 secondary (2,3) alkyl sulfates of the formula CH3 (CH2) x (CHOS03-M+) CH3 and CH3 (CH2) y (CHOS03'tv))CH2CHs where x and (y + 1) are integers of at least 7, preferably at least 9, and M is a water- solubilizing cation, especially sodium, unsaturated sulfates such as oleyl sulfate, the C10-C18 alkyl alkoxy sulfates ("AEXS"; especially x up to 7 EO ethoxy

sulfates), C0-Cg alkyl alkoxy carboxylates (especially the EO 1-5 ethoxycarboxylates), the C10-18 glycerol ethers, the C10-Cl8 alkyl polyglycosides and their corresponding sulfated polyglycosides, and C12-Cl8 alpha-sulfonated fatty acid esters. If desired, the conventional nonionic and amphoteric surfactants such as the C12-C1g alkyl ethoxylates ("AE") including the so-called narrow peaked alkyl ethoxylates and C6-C12 alkyl phenol alkoxylates (especially ethoxylates and mixed ethoxy/propoxy), C12-C1g betaines and sulfobetaines ("sultaines"), C10-C1 g amine oxides, cationic surfactants and the like, can also be included in the overall compositions. The C10-C1 N-alkyl polyhydroxy fatty acid amides can also be used. Typical examples include the C12-C1g N-methylglucamides. See WO 9,206,154. Other sugar-derived surfactants include the N-alkoxy polyhydroxy fatty acid amides, such as C10-C18 N-(3-methoxypropyl) glucamide. The N-propyl through N-hexyl C12-C1g glucamides can be used for low sudsing. C10-C20 conventional soaps may also be used. If high sudsing is desired, the branched-chain C10-C16 soaps may be used. Mixtures of anionic and nonionic surfactants are especially useful.

Other conventional useful surfactants are listed in standard texts.

Builders Detergent builders can optionally be included in the compositions herein to assist in controlling mineral hardness. Inorganic as well as organic builders can be used. Builders are typically used in fabric laundering compositions to assist in the removal of particulate soils.

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 1 % builder, preferably from 1 % to 80%. Liquid formulations typically comprise from 5% to 50%, more typically 5% to 30%, by weight, of detergent builder. Granular formulations typically comprise from 1 % to 80%, more typically from 5% to 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 1.0: 1 to 3.2: 1 and layered silicates, such as the layered sodium silicates described in U. S. 4,664,839. 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 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+1 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 DE 2,321,001.

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: MZln [(Alo2) z (sio2) y] XH2° wherein z and y are integers usually of at least 6, the molar ratio of z to y is in the range from 1.0 to 0, and x is an integer from 0 to 264, and M is a Group IA or IIA element, e. g., Na, K, Mg, Ca with valence n.

Useful aluminosilicate ion exchange materials are commercial 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.

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 [ (At02) i2 (Si02) i2] xH20 wherein x is from 20 to 30, especially 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 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,"polycarboxylate"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 materials. One important category of polycarboxylate builders encompasses the ether polycarboxylates, including oxydisuccinate, as disclosed in Berg, U. S.

3,128,287, U. S. 3,635,830. See also"TMS/TDS"builders of U. S. 4,663,071.

Suitable ether polycarboxylates also include cyclic compounds, particularly alicyclic compounds, such as those described in U. S. 3,923,679; 3,835,163; 4,158,635; 4,120,874 and 4,102,903.

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, pyromellitic, succinic acid, oxydisuccinic

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- dicarboxy-4-oxa-1,6-hexanedioates and the related compounds disclosed in U. S.

4,566,984. Useful succinic acid builders include the C5-C20 alkyl and alkenyl succinic acids and salts thereof. A particularly preferred compound of this type is dodecenylsuccinic 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 EP 0,200,263.

Other suitable polycarboxylates are disclosed in U. S 4,144,226 and in U. S.

3,308,067. See also U. S. 3,723,322.

Fatty acids, e. g., C12-C1g monocarboxylic acids such as oleic acid and/or its salts, 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 formulation 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.

Bleaching Compounds-Bleaching Agents and Bleach Activators The detergent compositions herein may optionally contain bleaching agents or bleaching compositions containing a bleaching agent and one or more bleach activators. When present, bleaching agents will typically be at levels of from 1% to 30%, more typically from 5% to 20%, of the detergent composition, especially for fabric laundering. If present, the amount of bleach activators will typically be from 0.1% to 60%, more typically from 0.5% to 40% of the bleaching composition comprising the bleaching agent-plus-bleach activator.

The bleaching agents used herein can be any of the bleaching agents useful for detergent compositions in textile cleaning or other cleaning purposes that are now known or become known. These include oxygen bleaches as well as other bleaching agents. Perborate bleaches, e. g., sodium perborate (e. g., mono-or tetra-hydrate) can be used herein.

Another category of bleaching agent that can be used without restriction encompasses percarboxylic acid bleaching agents and salts thereof. Suitable examples of this class of agents include magnesium monoperoxyphthalate hexahydrate, the magnesium salt of metachloro perbenzoic acid, 4-nonylamino-4- oxoperoxybutyric acid and diperoxydodecanedioic acid. Such bleaching agents are disclosed in U. S 4,483,781, U. S 740,446, EP 0,133,354, and U. S 4,412,934.

Highly preferred bleaching agents also include 6-nonylamino-6-oxoperoxycaproic acid as described in U. S 4,634,551.

Peroxygen bleaching agents can also be used. Suitable peroxygen bleaching compounds include sodium carbonate peroxyhydrate and equivalent "percarbonate"bleaches, sodium pyrophosphate peroxyhydrate, urea peroxyhydrate, and sodium peroxide. Persulfate bleach (e. g., OXONE, manufactured commercially by DuPont) can also be used.

A preferred percarbonate bleach comprises dry particles having an average particle size in the range from 500 micrometers to 1,000 micrometers, not more than 10% by weight of said particles being smaller than 200 micrometers and not more than 10% by weight of said particles being larger than 1,250 micrometers.

Optionally, the percarbonate can be coated with silicate, borate or water-soluble

surfactants. Percarbonate is available from various commercial sources such as FMC, Solvay and Tokai Denka.

Mixtures of bleaching agents can also be used.

Peroxygen bleaching agents, the perborates, the percarbonates, etc., are preferably combined with bleach activators, which lead to the in situ production in aqueous solution (i. e., during the washing process) of the peroxy acid corresponding to the bleach activator. Various non-limiting examples of activators are disclosed in U. S 4,915,854, and U. S 4,412,934. The nonanoyloxybenzene sulfonate (NOBS), 3,5,5-tri-methyl hexanoyl oxybenzene sulfonate (ISONOBS) and tetraacetyl ethylene diamine (TAED) activators are typical, and mixtures thereof can also be used. See also U. S. 4,634,551 for other typical bleaches and activators useful herein.

Highly preferred amido-derived bleach activators are those of the formulae: RlN (R5) C (O) R2C (O) L or R1 C (o) N (R5) R2C (O) L wherein R1 is an alkyl group containing from 6 to 12 carbon atoms, R2 is an alkylene containing from 1 to 6 carbon atoms, R5 is H or alkyl, aryl, or alkaryl containing from 1 to 10 carbon atoms, and L is any suitable leaving group. A leaving group is any group that is displaced from the bleach activator as a consequence of the nucleophilic attack on the bieach activator by the perhydrolysis anion. A preferred leaving group is phenyl sulfonate.

Preferred examples of bleach activators of the above formulae include (6- octanamido-caproyl) oxybenzenesulfonate, (6-nonanamidocaproyl) oxybenzene sulfonate, (6-decanamido-caproyl) oxybenzenesulfonate, and mixtures thereof as described in U. S. Patent 4,634,551, incorporated herein by reference.

Another class of bleach activators comprises the benzoxazin-type activators disclosed by Hodge et al in U. S. Patent 4,966,723. A highly preferred activator of the benzoxazin-type is: Still another class of preferred bleach activators includes the acyl lactam activators, especially acyl caprolactams and acyl valerolactams of the formulae:

wherein R6 is H or an alkyl, aryl, alkoxyaryl, or alkaryl group containing from 1 to 12 carbon atoms. Highly preferred lactam activators include benzoyl caprolactam, octanoyl caprolactam, 3,5,5-trimethylhexanoyl caprolactam, nonanoyl caprolactam, decanoyl caprolactam, undecenoyl caprolactam, benzoyl valerolactam, octanoyl valerolactam, decanoyl valerolactam, undecenoyl valerolactam, nonanoyl valerolactam, 3,5,5-trimethylhexanoyl valerolactam and mixtures thereof. See also U. S. Patent 4,545,784, issued to Sanderson, October 8,1985, incorporated herein by reference, which discloses acyl caprolactams, including benzoyl caprolactam, adsorbed into sodium perborate.

Bleaching agents other than oxygen bleaching agents are also known in the art and can be utilized herein. One type of non-oxygen bleaching agent of particular interest includes photoactivated bleaching agents such as the sulfonated zinc and/or aluminum phthalocyanines. See U. S. 4,033,718. If used, detergent compositions will typically contain from 0.025% to 1.25%, by weight, of such bleaches, especially sulfonate zinc phthalocyanine.

If desired, the bleaching compounds can be catalyzed by means of a manganese compound. Such compounds are well-known in the art and include, for example, the manganese-based catalysts disclosed in U. S. 5,246,621, U. S. 5,244,594; U. S. 5,194,416; U. S. 5,114,606; and EP 549,271A1,549,272A1,544,440A2, and 544,490A1; Preferred examples of these catalysts include Mniv2 (u-O) 3 (1,4,7- trimethyl-1,4,7-triazacyclononane) 2 (PF6) 2, MnII12 (u-O) 1 (u-OAc) 2 (1,4,7- trimethyl-1,4,7-triazacyclononane) 2 (CIO4) 2, Mn (u-0) e (1,4,7- triazacyclononane) 4 (CI04) 4, MnIIIMnIV4(u-O)1 (u-OAc) 2 7- triazacyclononane) 2 (CI04) 3, MnIV (1,4,7-trimethyl-1,4,7-triazacyclononane)- (OCH3) 3 (PF6), and mixtures thereof. Other metal-based bleach catalysts include those disclosed in U. S. Pat. 4,430,243 and U. S. 5,114,611. The use of manganese with various complex ligands to enhance bleaching is also reported

in the following US Patents: 4,728,455; 5,284,944; 5,246,612; 5,256,779; 5,280,117; 5,274,147; 5,153,161 ; and 5,227,084.

As a practical matter, and not by way of limitation, the compositions and processes herein can be adjusted to provide on the order of at least one part per ten million of the active bleach catalyst species in the aqueous washing liquor, and will preferably provide from 0.1 ppm to 700 ppm, more preferably from 1 ppm to 500 ppm, of the catalyst species in the laundry liquor.

Other preferred optional ingredients include enzyme stabilisers, polymeric soil release agents, materials effective for inhibiting the transfer of dyes from one fabric to another during the cleaning process (i. e., dye transfer inhibiting agents), polymeric dispersing agents, suds suppressors, optical brighteners or other brightening or whitening agents, chelating agents, fabric softening clay, anti-static agents, other active ingredients, carriers, hydrotropes, processing aids, dyes or pigments, solvents for liquid formulations and solid fillers for bar compositions.

Liquid detergent compositions can contain water and other solvents as carriers.

Low molecular weight primary or secondary alcohols exemplified by methanol, ethanol, propanol, and isopropanol are suitable. Monohydric alcools are preferred for solubilizing surfactant, but polyols such as those containing from 2 to 6 carbon atoms and from 2 to 6 hydroxy groups (e. g., 1,3-propanediol, ethylene glycol, glycerine, and 1,2-propanediol) can also be used. The compositions may contain from 5% to 90%, typically 10% to 50% of such carriers.

Granular detergents can be prepared, for example, by spray-drying (final product density 520 g/I) or agglomerating (final product density above 600 g/I) the Base Granule. The remaining dry ingredients can then be admixed in granular or powder form with the Base Granule, for example in a rotary mixing drum, and the liquid ingredients (e. g., nonionic surfactant and perfume) can be sprayed on.

The detergent compositions herein will preferably be formulated such that, during use in aqueous cleaning operations, the wash water will have a pH of between 6.5 and 11, preferably between 7.5 and 10.5. Laundry products are typically at pH 9-11. Techniques for controlling pH at recommended usage levels include the use of buffers, alkalis, acids, etc., and are well-known to those skilled in the art.

Method of use Also provided herein is a method for providing a delayed release of an active alcohol which comprises the step of contacting the surface to be treated with a material, preferably an aqueous medium comprising a compound or composition of the invention.

By"surface", it is meant any surface onto which the compound can deposit.

Typical examples of such material are fabrics, hard surfaces such as dishware, floors, bathrooms, toilet, kitchen and other surfaces in need of a delayed release of an active alcohol such as that with litter.

By"delayed release"is meant release of the active component (e. g perfume) over a longer period of time than by the use of the active (e. g., perfume) itself.
