Description
DETERGENT COMPOSITIONS THAT COMPRISE NON-IONIC POLYPHILIFYING ETHERS AND ENZYMES LIPflSfl
FIELD OF THE INVENTION
The present invention relates to a detergent composition comprising lipase enzymes and nonionic polysaccharide ethers that provide improved stain removal.
BACKGROUND OF THE INVENTION
The use of lipase enzymes incorporated in detergent compositions to aid in the removal of triglyceride or fatty ester stains is well known. For example, UO 92/05249 describes certain variants of lipase enzyme for improved properties and methods for their production. UO 94/25577 discloses novel lipase enzyme variants and detergent compositions comprising from 0.02 to 200 g per gram of detergent additive of said lipase enzymes. Generally, the functioning of lipase enzyme stain removal is directly related to its concentration in the detergent composition, so that an increase in the amount of lipase enzyme increases the performance of stain removal. However, it has been observed that under stress conditions, such as the use of short cycles of washing machine, or at low temperatures or in the presence of highly stained substrates, the optimal functioning of the enzyme lipase at a certain level is achieved. Increasing the lipase enzyme level beyond this amount does not result in the improved performance of improved spot removal. In addition, another disadvantage of the increase in the amount of enzyme lipase present in a detergent composition is the resulting increase in the problem of malodor known in the washed fabrics. It has now been discovered that the operation of stain removal of a lipase enzyme can be unexpectedly improved under such conditions by its use in combination with a non-ionic polysaccharide ether. Another advantage of the present invention is that the benefits of stain removal are observed after completing only one wash cycle. This is in contrast to the benefits of dirt release and / or anti-redeposition associated with non-ionic polysaccharide ethers and also lipase enzymes that require multi-cycle application in order to observe these benefits. Another advantage of the present invention is that there are no associated malodor problems. The use of nonionic polysaccharide ethers as soil release agents has been described in the art. For example, the Patent of E.U.A. 4 470 326 discloses a laundry product comprising a substrate material coated with a soil release polymer for improved cleaning performance of hydrophobic soils on synthetic and synthetic blends. The soil release polymers include alkyl or hydroxyalkyl cellulose ethers having a molar degree of substitution (ds) of 1.5 to 2.7 and an average molecular weight of 2000 to 100000, preferably 10000 to 30000. Enzymes are described, but not specifically mentions lipase. The Patent of E.U.A. 4 174 305 discloses detergent compositions comprising LAS and etherified cellulose soil release agents having a ds of up to 3 and a dp of 100 to 10000. Enzymes are described, specifically proteolytic and lipolytic enzymes, but not their levels. Lipases are not included in the examples. The Patent of E.U.A. No. 4,136,038 discloses fabric conditioning compositions comprising cellulose ethers having a molecular weight of from 3000 to 10000 and ds from 1.8 to 2.7 and from 0.05% to 2% of detergency enzymes selected from protease, lipase, and ilase. and mixtures thereof. There are no exemplary compositions comprising lipase and cellulose ethers. EPO 495 257 describes a compact detergent composition comprising high activity cellulase. Anti-redeposition agents are described such as cellulose derivatives, in particular methylcellulose, carboxymethylcellulose (CMC) and hydroxyethylcellulose. Its values of dp and ds are not described. Other enzymes are described, including lipase, but not the levels. Thus, an object of the present invention is to provide a detergent composition comprising a lipase enzyme which provides triglyceride and improved fatty ether-based spot removal operation, in particular under tension conditions. None of the prior art documents identified describe the benefits of the operation of the combination of lipase enzymes and nonionic polysaccharide ethers co or in the present invention.
BRIEF DESCRIPTION OF THE INVENTION
The present invention relates to a detergent composition comprising at least 1% of a surfactant characterized in that said detergent composition comprises the combination of a lipase enzyme with a nonionic polysaccharide ether having a molecular weight of more than 10000, said enzyme lipase having an activity such that said detergent composition has an activity of at least 0.001LU per milligram. All amounts, levels and percentages are given as weight% of the detergent composition unless otherwise indicated.
DETAILED DESCRIPTION OF THE INVENTION
In accordance with the present invention the detergent composition comprises as an essential component an enzyme lipase in combination with a nonionic polysaccharide ether.
ENZYME LIPASE
The enzymes lipases suitable for use in detergents include those produced by microorganisms of the Pseudomonas group, such as Pseudomona st? Tzeri ATCC
19. 154, as described in British Patent 1,372,034. See also lipases in Japanese Patent Application 53,20487, open for public inspection on February 24, 1987. This lipase is available from Amano Pharmaceutical Co. Ltd., Nagoya, Japan, under the trademark Lipase P "Amano" , which is hereinafter referred to as "Amano-P". Other commercial lipases include Arnano-CES, ex Chro obacter viscosum lipases, for example. Chromobacter viscosum var. lipolyctu NRRLB 3673, commercially available from Toyo Jozo Co., Tagata, Japan; and also the lipases from Chrornobacter viscosum from U.S. Boichemical Corp., E.U.A. and Disoynth Co., The Netherlands, and the lipases of ex Pseudomonas gladioli. The enzyme LIPOLASE derived from Humicola lan? Ginosa and which is commercially available from Novo (see also EPO 341,947) is a preferred lipase for use herein. Another preferred lipase is the D96L variant of the lipolytic enzyme of the native lipase Hu icola lan? Ginosa. Very preferred is the Humicola lan? Ginous strain DSM 4106. By variant D96 of lipolytic enzyme is meant the lipase variant as described in patent application UO 92/05249 viz. wherein the residue of aspartic acid (D) of the native lipase ex H? mycola lanuginosa in position 96 changes to Leucine (L). In accordance with this nomenclature, said substitution of aspartic acid to Leucine in position 96 is shown as: D96L.

DETERGENT IMPROVERS
Builders may optionally be included in the compositions herein to help control the hardness of minerals. Inorganic and organic detergent builders can be used. Builders are typically used in fabric washing compositions to help remove particulate dirt. The level of builder can vary widely depending on the final use of the composition and its desired physical form. When present, the compositions will typically comprise at least about 1% detergency builder. Liquid formulations typically comprise from 5% to 50%, more typically from about 5% to 30%, by weight, of builder. The granulated formulations typically comprise from 10% to 80%, more typically from 15% to 50% by weight, of the builder. However, lower or higher detergency builder levels are not excluded. Detergency builders for inorganic detergents and q include P include, but are not limited to, the alkali metal, ammonium and alkanolammonium salts of polyphosphates (exemplified by the glassy polymeric tripolyphosphates, pyrophosphates and metaphosphates), phosphonates, phytic acid , silicates, carbonates (including bicarbonates and sesquicarbonates), sulfates and aluminosilicates (see, for example, US Patents 3,159,381; 3,213,030; 3,422,021; 3,400,148 and 3,422,137). However, phosphate-free builders are required in some scenarios. Surprisingly, the compositions herein work well even in the presence of so-called "weak" detergency builders (compared to phosphates) such as citrate, or in the so-called "underconstrictive" situation that could occur with silicate detergent builders stratified or zeolite. Examples of silicate builders are alkali metal ethosilicates, particularly those having a Si? 2: N 2? Ratio. on the scale from 1.6: 1 to 3.2: 1; and stratified silicates, such as the layered sodium silicates described in U.S. Patent 4,664,839, issued May 12, 1987 to H. P. Rieck. NaSKS-6 is the trade name for crystalline layered silicate sold by Hoechst (commonly abbreviated as "SKS-6" herein). Unlike zeolite builders, Na SKS-6 and other water-soluble silicates or disilicates useful herein do not contain aluminum. NaSKS-6 is the form of 6-N 2 SiOs of stratified silicate and can be prepared by methods such as those described in German applications DE-A-3,417,649 and DE-A-3,742,043. SKS-6 is a highly preferred layered silicate for use herein, but other layered silicates, such as those having the general formula NaMSi? 2x +? Can be used herein. yH2? 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. Some other stratified silicates from Hoechst include NaSKS-5, NaSKS-7 and NaSKS-ll like the forms -, ß- and t-. As noted above, most preferred for use herein is delta-Na2Si0s (NaSKS-6 form). Other silicates can also be used, such as for example magnesium silicate, which can serve as a tightening agent in granulated formulations, as a stabilizing agent for oxygen bleaches and as a component of foam control systems. Examples of carbonate builders are alkali metal and alkali metal carbonates as described in German Patent Application No. 2,321,001 published November 15, 1973. Aluminosilicate builders are useful in the present invention. Aluminosilicate builders are of great importance in most heavy duty granular detergent compositions currently manufactured, and can also be a significant detergent builder ingredient in liquid detergent formulations. The aluminosilicate builders include those that have the empirical formula: Mi C (YES? 2) », (zAl? 2) and 3 XH2O where w, zyy are integers of at least 6, the molar ratio of zay is in the scale 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 may be of crystalline or amorphous structure and may be naturally occurring or synthetically derived aluminosilicates. A method for producing aluminosilicate ion exchange materials is described in the U.S. Patent. 3,985,669, Krunmel et al. Issued October 12, 1976. The 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 one Especially preferred embodiment, the crystalline aluminosilicate ion exchange material has the formula: Nai2 C (AIO2) 12 (SIO2) 12"XH2O wherein x is from about 20 to about 30, especially 27. The material is known as Zeolite A. Dehydrated zeolites (x = 0-10) can also be used herein., the aluminosilicate has a particle size of approximately 0.1-10 microns in diameter. Organic builders suitable for the purposes of the present invention include, but are not limited to, a wide variety of polycarboxylate compounds. As used herein, "polycarboxylates" refers to compounds which have a plurality of carboxylate groups, preferably at least 3 carboxylates. Polycarboxylate builders can generally be added to the composition in acid form, but can also be added in the form of a neutralized salt. When used in the salt form, alkali metals such as sodium, potassium and lithium, or alkanolammonium salts are preferred. Included among the polycarboxylate detergent improvers are a variety of useful material categories. An important category of polycarboxylate detergent enhancement encompasses ether polycarboxylates, including oxydisuccinate, as described in Berg, U.S. Pat. 3,128,287, issued April 7, 1964, and Larnberti et al., Patent of E.U.A. 3,635,830, issued January 18, 1972. See also detergency builders of "TMS / TDS" of the U.S. Patent. No. 4,663,071, issued to Bush et al. On May 5, 1987. Suitable ether polycarboxylates also include cyclic compounds, particularly alicyclic compounds, such as those described in U.S. Pat. 3,923,679; 3,835,163; 4,158,635; 4,120,874 and 4,102,903. Other useful builders include ether hydroxypolycarboxylates, maleic anhydride copolymers with ethylene or vinyl methyl ether, 1,3,5-trihydroxybenzene, 6-trisulonic acid, and carboxymethyl-oxysuccinic acid, the various metal salts of alkali, ammonium and substituted ammonium of polyacetic acids such as ethylenediaenetetraacetic acid and nitriloacetic acid, as well as polycarboxylates such as elitic acid, succinic acid, oxydiscicynic acid, polymaleic acid, benzene 1,3,5-tricarboxylic acid, carboxymethyloxysuccinic, and soluble salts thereof. Citrate detergent builders, for example, citric acid and soluble salts thereof (particularly sodium salt), are polycarboxylate builders of particular importance for heavy duty liquid detergent formulations because of their availability from renewable resources. and its biodegradability. The citrates can also be used in combination with detergent builders of zeolite and / or layered silicate. The oxidisuccinatoe are also especially useful in said 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 described in the U.S.A. 4,566,984, Bush, issued January 28, 1986. 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: lauryl succinate, iristyl succinate, palmitinyl succinate, 2-dodecenylsuccinate (preferred), 2-? Enta-decenylsuccinate and the like. Lauryl succinates are the preferred builders in this group, and are described in European patent application 86200690.5 / 0,200,263, published November 5, 1986. Other suitable polycarboxylates are described in the U.S. Patent. 4,144,226, Crutchfield et al., Issued March 13, 1979 and in the U.S. Patent. 3,308,067, Diehl, issued March 7, 1967. See also Patent of U.S.A. Diehl, 3,723,322. Fatty acids, for example, C12-C18 monocarboxylic acids, can also be incorporated into the compositions alone, or in combination with the aforementioned builders, especially citrate and / or s? Ccinate builders, to provide additional detergency builder activity. Such use of fatty acids will generally result in decreased foam formation, which should be taken into account by the formulator.

The detergent compositions herein may also optionally contain one or more iron and / or manganese quenching agents. Such chelating agents can be selected from the group consisting of incarboxylates, phosphonates, polyfunctionally substituted aromatic q-elastinating agents and mixtures thereof, all as defined hereinafter. Without intending to be limited to theory, it is believed that the benefit of these materials is due in part to their exceptional ability to remove iron and manganese ions from washing solutions by forming soluble chelators. Aminocarboxylates useful as optional chelating agents include ethylenediaminetetraacetates, N-hydroxyethyleneadiarninotriacetates, nitrilotriacetates, ethylenediaenotetrapropionates, triethylenetriaminehexacetates, diethylenetriarninopentaacetates and ethanololdiglicines, alkali metal salts, ammonium and substituted ammonium thereof and mixtures thereof.

Suitable polymeric dispersing agents include polymeric polycarboxylates and polyethylene glycols, although others known in the art may also be used. It is believed, although not intended to be limited by theory, that polymeric dispersing agents increase the performance of the overall detergency builder, when used in combination with other detergency builders (including lower molecular weight polycarboxylates) by growth inhibition of crystals, peptization of dirt release in particles and anti-redeposition. 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, esaconic acid, citraconic acid, methylenemalonic acid. The presence of the polyarmer polycarboxylates in the present or polymer segments, which do not contain carboxylate radicals such as vinyl methyl ether, styrene, ethylene, etc., is suitable provided that said segments do not constitute more than about 40% by weight. Particularly suitable polymeric polycarboxylates can be derived from acrylic acid. Said 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, most preferably from about 4,000 to 7,000, and most preferably from about 4,000 to 5,000. The water-soluble salts of said acrylic acid polymers can include, for example, the alkali metal, ammonium and substituted ammonium salts. Soluble polymers of this type are known materials. The use of polyacrylates of this type in detergent compositions has been described, for example, in Diehl, U.S. Pat. 3,308,067, issued March 7, 1967. Copolymers based on acrylic / maleic acid 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 said copolymers in the acid form preferably ranges from about 2,000 to 100,000, more preferably from about 5,000 to 90,000, most preferred from 7,000 to 80,000. The ratio of acrylate segments to maleate loe in said copolymers generally ranges from about 30: 1 to about 1: 1, most preferably from about 70:30 to 30:70. The water soluble salts of said acrylic acid / maleic acid copolymers may include, for example, the alkali metal, ammonium and substituted ammonium salts. Soluble acrylate / random 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 describes also said polymers comprising hydroxypropylacrylate. Still other useful dispersing agents include maleic / acrylic / vinyl alcohol or acetate terpolyneros. Said materials are also described in EP 193,360, including, for example, the terpolymer 45/45/10 of acrylic / maleic / vinyl alcohol. Another polymeric material that can be included is polyethylene glycol (PEG). The PEG can exhibit performance of dispersing agent and can act as a clay rejection-anti-redeposition agent. Typical molecular weight scales for these purposes range from about 500 to about 100,000, more preferably from about 1,000 to about 50,000 and most preferably from about 1,500 to about 10,000. Polyamino acid dispersing agents such as polyaspartate and polyglutamate, especially in conjunction with zeolite builders, can also be used. Dispersing agents such as those of polyaspartate preferably have a molecular weight (avg.) Of about 10,000.
ARCILLA SOILING / ANTI-REDEPOSITION REMOVAL AGENTS
The compositions of the present invention may also optionally contain water-soluble ethoxylated amines that have clay removal and antiredeposition properties. Granular detergent compositions containing these compounds typically contain from about 0.01% to about 10.0% by weight of the water-soluble ethoxylated amines; Liquid detergent compositions typically contain about 0.01% to about 5%. The preferred soil replenishing and anti-redeposition agent is tetraethylene pentane ethoxylated. Example ethoxylated amines are more fully described in the U.S. Patent. 4,597,898, VanderMeer, issued July 1, 1986. Another group of clay dirt remover / anti-redeposition agents are the cationic compounds described in European Patent Application 111,965, Oh and Gosselink, published June 27, 1984. Other clay soil removers / anti-redeposition agents that may be used include the ethoxylated amine polymers described in European Patent Application 111,984, Gosselink, published June 27, 1984; the zwitterionic polymers described in European Patent Application 112,592, Goeselink, published on July 4, 1984; and the amine oxides described in the U.S. Patent. No. 4,548,744, Connor, issued October 22, 1985. Other clay removers and / or anti-redeposition agents known in the art can be used in the compositions herein. Another type of preferred anti-redeposition agent includes the carboxymethyl cellulose (CMC) materials. These materials are well known in the art.
INHIBITORS OF COLORING TRANSFER AGENTS
The compositions of the present invention can also include one or more materials effective to inhibit the transfer of dyes from one fabric to another during the cleaning process. In general, said dye transfer inhibiting agents include polyvinylpyrrolidone polymers, polyamine N-oxide polymers, copolymers of N-vinyloxydolidone and N-vinylimidazole, manganese phthalocyanine, peroxidases and mixtures thereof. If used, these agents typically comprise from 0.01% to 10% by weight of the composition, preferably from 0.01% to 5%, and most preferably from 0.05% to 2%. Very specifically, the preferred polyamine N-oxide polymers for use herein contain units having the following structural formula: R-AH-P; wherein P is a polymerizable unit to which a N-O group can be attached or the N-O group can be part of the polymerizable unit or the N-O group can be attached to both units; A is one of the following structures: -NC (O) -, -C (0) 0-, -S-, -0-, -N =; x is 0 or 1; and R is aliphatic, aliphatic, ethoxylated, aromatic, heterocyclic or alicyclic groups or any combination thereof to which the nitrogen of the N-O group can be attached or the N-O group is part of these groups. Preferred polyamine N-oxides are those in which R is a heterocyclic group such as pyridine, pyrro !, irnidazole, pyrroline, piperidine and derivatives thereof. The N-O group may be represented by the following general structures:
0 0 (Ri)? - N- (R2) y = N- (R?) "(R3) z
wherein Ri, R2, R3 are aliphatic, aromatic, heterocyclic or alicyclic groups or combinations thereof; x, y and z are 0 or 1; and the nitrogen of the N-O group can be attached or forms part of any of the aforementioned groups. The amine oxide unit of the polyamine N-oxides has a pKa < 10, preferably pKa < 7, very preferably still? Ka < 6. Any polymer base structure can be used as long as the amine oxide polymer formed is soluble in water and has dye transfer inhibiting properties. Examples of suitable polymeric base structures are polyvinyls, polyalkylenes, polyesters, polyethers, polyamide, polyimides, polyacrylates and mixtures thereof. These polymers include random or block copolymers wherein one type of monomer is an amine N-oxide and the other type of monomer is an N-oxide. The amine N-oxide polymers typically have an amine to amine N-oxide ratio of 10: 1 to 1: 1,000,000. However, the number of amine oxide groups present in the polyamine oxide polymer can be varied by appropriate copolymerization or by an appropriate degree of N-oxidation. Polyarnine oxides can be obtained in almost any degree of polymerization. Typically, the average molecular weight is within the range of 500 to 1,000,000; very preferred from 1,000 to 500,000; I still prefer 5,000 to 100,000. This preferred class of materials can be referred to as "PVNO". The most preferred polyamine N-oxide useful in the detergent compositions herein is poly-4-vinylp.i N-oxide. Ridinol has an average molecular weight of about 500,000 and an amine to amine N-oxide ratio of about 1: 4. Copolymers of N-vinylporrolidone polymers and
N-vinylniridazole (also known as "PVPVI") are also preferred for use herein. Preferably, the PVPVI has an average molecular weight in the range of 5,000 to 1,000,000, most preferably 5,000 to 200,000 and most preferably even 10,000 to 20,000. (The average molecular weight scale is determined by light scattering as described in Barth, and other Chemical Analysis, Vol. 113. "Modern Methods of Polymer Characterization", the descriptions of which are incorporated herein by reference). PVPVI copolymers typically have a molar ratio of N-vinylimidazole to N-vinylpyrrolidone from 1: 1 to 0.2: 1, most preferably from 0.8: 1 to 0.3: 1, most preferably from 0.6: 1 to 0.4: 1. These copolymers can be either linear or branched. The compositions of the present invention may also employ a polyvinylpyrrolidone ("PVP") which has an average molecular weight of from about 5,000 to about 400,000, preferably from about 5,000 to about 200,000, and most preferably still from about 5,000 to approximately 50,000. PVP's are known to those skilled in the field of detergents; see, for example, EP-A-262,897 and EP-A-256,696, incorporated herein by reference. The PVP-containing compositions may also contain polyethylene glycol ("PEG") having an average molecular weight of from about 500 to about 100,000, preferably from about 1,000 to about 10,000. Preferably, the ratio of PEG to PVP on a basis of ppm assorted in wash solutions is from about 2: 1 to about 50: 1, and most preferably from about 3: 1 to about 10: 1. Lae detergent compositions herein may also optionally contain from about 0.005% to 5% by weight of certain types of hydrophilic optical brighteners that also provide a dye transfer inhibiting action. If used, the compositions herein will preferably comprise from about 0.01% to 1% by weight of said optical brighteners. The hydrophilic optical brighteners useful in the present invention are those which have the structural formula:
wherein Ri is selected from anilino, N-2-bis-hydroxyethyl and NH-2-hydroxyethyl; R 2 is selected from N-2-bis-hydroxyethyl, N-2-hydroxyethyl-N-methylamino, morphino, chloro and amino; and M is a salt forming cation such as sodium or potassium. When in the above formula, Ri is anilino, R2 is N-2-bis-hydroxyethyl and M ee a cation such as sodium, the brightener is acid 4,4 ', bisC (4-anilino-6- (N-2- bis-hydroxyethyl) -s-triazin-2-yl) aminol-2,2'-stilbenedisulfonic acid and disodium salt. This particular brightener species is commercially marketed under the trade name Tinopal-UNPA-GX by Ciba-Geigy Corporation. Tinopal-UNPA-GX is the preferred hydrophilic optical brightener useful in the detergent compositions of the present invention.
When in the above formula R1 is anilino, R2 is N-2-hydroxyethyl-N-2-rnedilarinino and M is a cation such as sodium, the brightener is the disodium salt of 4,4'-bisC (4-anilino) -6- (N-2-hydroxyethyl-N-methylamino) -s-triazin-2-yl) amino] -2,2'-eethylbenzene sulfonic acid. Eeta species of particular brightener is commercially marketed under the trade name Tinopal 5BM-6X by Ciba-Geigy Corporation. When in the above formula R1 is anilino, R2 is morphino and M is a cation such as sodium, the brightener is the sodium salt of 4,4'-bisC (4-anilino-6-morphino-s-triazin-2) -yl) amino32, 2 '-stilbenedisulfonic. This particular kind of brightener is sold commercially under the trade name Tinopal AMS-GX by Ciba-Geigy Corporation. The specific optical brightener species selected for use in the present invention provides especially effective dye transfer inhibition performance benefits when used in combination with the selected polymeric dye transfer inhibiting agents described above. The combination of said selected polymeric materials (e.g., PVNO and / or PVPVI) with said selected optical brighteners (e.g., Tinopal UNPA-GX, Tinopal 5BM-GX and / or Tinopal AMS-GX) provide significantly better dye transfer inhibition in aqueous wash solutions than either those two components of detergent composition when used alone. Without being limited to the theory, it is believed that such brighteners work in this way because they have high affinity for fabrics in the wash solution and therefore they deposit relatively quickly on these fabrics. The degree to which the brighteners are deposited on the fabrics in the wash solution can be defined by a parameter called "exhaustion coefficient". The depletion coefficient is in general the ratio of a) the polishing material deposited on the cloth to b) the initial polish concentration in the wash liquor. Brighteners with relatively high depletion coefficients are most suitable for inhibiting dye transfer in the context of the present invention. Of course, it will be appreciated that other types of conventional optical brightener compounds may optionally be present in the compositions herein to provide conventional "brightness" benefits to the fabrics, rather than a true dye transfer inhibiting effect. Said use is conventional and well known for detergent formulations. In accordance with the present invention the detergent composition can comprise any other ingredient commonly employed in conventional detergent compositions such as soaps, suds suppressors, softeners, brighteners, additional enzymes and enzyme stabilizers.
USE OF THE COMBINATION OF NON-IONIC POLYPHILIFYING ETHERS AND LIPflSfl ENZYMES
The compositions of the present invention can be used in laundry detergent compositions, fabric treatment compositions and fabric softening compositions in addition to hard surface cleaners. The compositions can be formulated as granules, sticks, pastes, powders and detergent liquids. The detergent compositions are manufactured in a conventional manner, for example, in the case of powder detergent compositions, spray drying or spray mixing methods can be used. The combination of polysaccharide ether and lipase enzyme of the present invention is present at aqueous concentrations of 1ppm to 100ppm, preferably from 5ppm to 300ppm in the wash solution, preferably at a pH of 7 to 11, preferably 9 to 10.5. The present invention also relates to a method for washing fabrics comprising said fabric contacting an aqueous liquid containing conventional detersive ingredients described herein in addition to the enzyme lipase and nonionic polysaccharide ether of the present invention. In a preferred method fabrics of polyether and polyester-cotton blends are used.
