Description: HIGH ACTIVE DETERGENT COMPOSITION CONTAINING OLEOYL SARCOSINATES FOR IMPROVED SOLUBILITY FIELD OF THE INVENTION The present invention generally relates to a detergent composition having improved solubility in aqueous laundering solutions. More particularly, the invention is directed to a detergent composition containing at least 10% by weight of a surfactant system containing one or more surfactants selected from the group of alkyl sulfates, alkyl ethoxy sulfates, secondary alkyl sulfates and mixtures thereof, and an effective amount of oleoyl sarcosinate for improved cleaning performance and solubility or agglomerate dissolution in aqueous laundering solutions. BACKGROUND OF INVENTION Typically, conventional detergent compositions contain mixtures of various surfactants in order to remove a wide variety of soils and stains from surfaces. For example, various anionic surfactants, especially the alkyl benzene sulfonates, are useful for removing particulate soils, and various nonionic surfactants, such as the alkyl ethoxylates and alkylphenol ethoxylates, are useful for removing greasy soils. While the art is replete with a wide variety of surfactants for those skilled in the art of detergent formulation, most of the available surfactants are specialty chemicals which are not suitable for routine use in low cost items such as home laundering compositions. The fact remains that many home-use laundry detergents still comprise one or more of the conventional alkyl benzene sulfonates or primary alkyl sulfate surfactants. The limited solubility of alkyl sulfate surfactants including both primary and secondary alkyl sulfates is especially prevalent in modern granular laundry detergents which are typically used in cold temperature (e.g. 5°C to 30°C) washing solutions and are formulated in "condensed" or "compact" form for low dosage usage. For the consumer, the smaller package size attendant with compact detergent products provides for easy storage and handling. For the manufacturer, unit storage costs, shipping costs and packaging costs are lowered. The manufacture of acceptable compact or condensed granular detergents has its difficulties. In a typical compact detergent formulation, the so-called "inert" ingredients such as sodium sulfate are substantially eliminated. However, such ingredients do play a role in enhancing solubility of conventional detergents. As a consequence, compact detergents often suffer from solubility problems, especially in cold temperature laundering solutions. Moreover, conventional compact or low density detergent granules are usually prepared by spray drying processes which result in extremely porous detergent particles that are quite amenable to being dissolved in aqueous washing solutions. By contrast, compact detergents are typically comprised of less porous, high density detergent particles which are less soluble. Thus, since the compact form of granular detergents typically comprise particles or granules which contain high levels of detersive ingredients with little or no room for solubilizing agents, and since such particles are intentionally manufactured at high bulk densities, the net result can be a substantial problem with regard to in-use solubility. Accordingly, there remains a need for a detergent composition which has improved solubility, especially in cold temperature washing solutions. This need is especially prevalent in the art of compact or high density detergents currently being used by consumers. There is also a need for such a detergent composition which also has improved solubility under high water hardness conditions. BACKGROUND ART Oleoyl sarcosinate is described in the following patents and publications: U.S. 2,542,385; U.S. 3,402,990; U.S. 3,639,568; U.S. 4,772,424; U.S. 5,186,855; European _ Patent Publication 505,129; British Patent Publication 1,211,545; Japanese Patent Publication 59/232194; Japanese Patent Publication 62/295997; Japanese Patent Publication 02/180811; and Chemical Abstracts Service abstracts No.s 61:3244q, 70:58865x, and 83:181020p. SUMMARY OF THE INVENTION The present invention meets the needs identified above by providing a detergent composition which exhibits improved solubility or dissolution of the surfactants in aqueous washing solutions as well as under high water hardness conditions resulting in improved cleaning performance. The detergent composition comprises a high level (at least 10% by weight) of a surfactant system containing one or more surfactants selected from the group of alkyl sulfates, alkyl ethoxy sulfates, secondary alkyl sulfates and mixtures thereof, in combination with an effective amount of oleoyl sarcosinate. The solubility of the anionic surfactants in the surfactant system is unexpectedly improved. As used herein, the phrase "improved solubility" means that the detergent agglomerates or granules dissolution in the laundering solution is increased by a specified amount, e.g. 5%. The extent of the increased agglomerate or granular dissolution can be measured by the amount of the anionic surfactants of the detergent composition solubilized which is enhanced by at least 5% in the laundering solution when employed in the manner of this invention, as compared to the solubility of the same anionic surfactants per se, under the same test conditions (i.e. water temperature and pH, stirring speed and time, particle size, water hardness, and the like). As used herein, the term "agglomerates" refers to particles formed by agglomerating particles which typically have a smaller mean particle size than the formed agglomerates. All percentages, ratios and proportions used herein are by weight, unless otherwise specified. All documents including patents and publications cited herein are incorporated herein by reference. In accordance with one aspect of the invention, a detergent composition is provided. Specifically, the detergent composition comprises at least 10% by weight of a detersive surfactant system containing at least one surfactant selected from the group consisting of alkyl sulfates, alkyl ethoxy sulfate, secondary alkyl sulfates and mixtures thereof. The composition also contains an effective amount of oleoyl sarcosinate to increase the overall solubility and cleaning performance of the detergent composition. Another embodiment is directed to a high density detergent composition comprising at least 10% by weight of a detersive surfactant system containing at least one surfactant selected from the group consisting of alkyl sulfates, alkyl ethoxy sulfate, secondary alkyl sulfates and mixtures thereof, and at least about 0.5% of oleoyl sarcosinate. The composition has a density of at least 600 g/1 to render it suitable for commercialization as a compact detergent. In one embodiment of the invention, the detergent composition further contains at least about 1% by weight of a detergency builder. Preferably, the detergency builder is selected from the group consisting of sodium carbonate, zeolites and mixtures thereof. Optionally, the detergent composition of the invention also comprises adjunct ingredients selected from the group consisting of bleaches, bleach activators, suds suppressors, enzyme stabilizers, polymeric dispersing agents, dye transfer inhibitors and soil release agents. In other embodiments, the deteregent composition of the invention includes from about 0.1% to about 45% by weight of other surfactants such as alkyl benzene sulfonates, alkyl ester sulfonates; and, from about 0.1% to about 45% by weight of nonionic surfactants selected from the group consisting of alkyl ethoxylates, alkyl phenol alkoxylates, alkylpolyglucosides, and mixtures thereof. In yet another embodiment of the invention, a detergent composition as described herein is in the form of a laundry bar. Another aspect of the invention is directed to a method of laundering soiled fabrics comprising the step of contacting the soiled fabrics with an aqueous medium containing an effective amount of a detergent composition according to the invention. Accordingly, it is an object of the invention to provide a high active detergent composition which has improved solubility, especially in cold temperature washing solutions and especially when the detergent composition is formulated as a compact or high density detergent currently being used by consumers. The compositions also provide excellent color care for dyed fabrics and excellent skin mildness for handwash operations. These and other objects, features and attendant advantages of the invention will become apparent to those skilled in the art from a reading of the following detailed description of the preferred embodiment and the appended claims. DETAILED DESCRIPTION OF THE INVENTION The invention is directed to a high active detergent composition having improved solubility and cleaning performance. A multitude of consumers around the world launder soiled clothes in conventional washing machines unique to their particular geographic location. Typically, these conventional washing machines launder the soiled clothes in water supplied at relatively cold temperatures, for example in range of 5°C to 30°C, and at high hardness concentrations, e.g. 7 grains/gallon (rich with Ca and Mg ions). Most of the modern day consumers also use compact or condensed laundry detergents to accomplish their laundering needs. Under the aforementioned conditions, solubility of current detergents in aqueous laundering solutions has been a problem. This problem is especially exacerbated when the detergent composition has high levels of anionic surfactants such as alkyl sulfates, alkyl ethoxy sulfate and/or secondary alkyl sulfates which are not particularly amenable to dissolution in aqueous laundering solutions, especially those kept at cold temperatures. It has been found that the solubility and cleaning performance of a high-active (i.e. greater than 10% of anionic surfactants) detergent composition can be increased by incorporating an effective amount of oleoyl sarcosinate into the composition. To that end, the preferred detergent composition of the invention comprises from at least about 10%), preferably from about 10% to about 55%, and most preferably from about 15% to about 45%o by weight of a surfactant system selected from the group consisting of alkyl sulfates, alkyl ethoxy sulfate, secondary alkyl sulfates and mixtures thereof. Also, the composition contains an effective amount of oleoyl sarcosinate to improve the solubility and cleaning performance of the composition. Preferably, the detergent composition herein is formulated and processed to achieve a density of at least 600 g/1 for purposes of producing a "compact" detergent product. Further, it is preferable for the detergent composition to be in the form of "agglomerates" as opposed to spray dried granules. The "improved solubility" achieved by the detergent composition is concerned with enhanced solubility of the surfactants contained in the surfactant system. Preferably, the improvement represents at least a 5% increase in solubility of the anionic surfactants in the wash solution over the solubility of the same surfactants if they were dissolved alone or without being contained in a detergent composition as defined herein. More preferably, the solubility improvement is from about 10% to about 50%. As those skilled in the art will appreciate, any comparison of anionic surfactant solubility should be completed under the same laundering conditions, e.g. water temperature, hardness and pH, stirring speed and time, and particle size. Those skilled in the art should also appreciate the numerous ways in which the amount of the surfactant system in the washing solution can be determined. For example, in the so-called "catSO3" titration technique, samples of the aqueous laundering solution containing the detergent composition can be taken after one minute and filtered with 0.45 um nylon filter paper, after which the filtered solution can be titrated with a cationic titrant, which can be commercially purchased, e.g. from Sigma Chemical Company under the trade name Hyamine, in the presence of anionic dyes. From the foregoing, the amount of anionic surfactant which was dissolved in the washing solution can be determined. Oleoyl Sarcosinate The present invention compositions comprise oleoyl sarcosinate, in its acid and/or salt form selected as desired for the compositions and uses herein, having the following formula: wherein M is hydrogen or a cationic moiety. Preferred M are hydrogen and alkali metal salts, especially sodium and potassium. Oleoyl sarcosinate is commercially available, for example as Hamposyl O supplied by W. R. Grace & Co. Oleoyl sarcosinates according to the present invention are present in an effective amount, which typically comprises from about 0.5%ι to about 80%, preferably from about 1% to about 40%o, and most preferably from about 2% to about 30%, of oleoyl sarcosinate by weight of the detergent composition. In addition to the commercially-available oleoyl sarcosinate, oleoyl sarcosinate useful herein can also preferably be prepared from the ester (preferably the methyl ester) of oleic acid and a sarcosine salt (preferably the sodium salt) under anhydrous reaction conditions in the presence of a base catalyst with a basicity equal to or greater than alkoxide catalyst (preferably sodium methoxide). For example, the reaction may be illustrated by the scheme: NaOCH 3 (cat) This salt may optionally be neutralized to form the oleoyl sarcosinate in its acid form. The preferred method for preparing oleoyl sarcosinate is conducted at a temperature from about 80°C to about 200°C, especially from about 120°C to about 200°C. It is preferred to conduct the reaction without solvent although alcohol solvents which have a boiling point of at least 100°C and are stable to the reaction conditions (ie. glycerol is not acceptable) can be used. The reaction may proceed in about 85% yield with a molar ratio of methyl ester reactant to sarcosine salt reactant to basic catalyst of about 1:1:0.05-0.2. Methyl ester mixtures derived from high oleic content natural oils (preferably having at least about 60%, more preferably at least about 75%, and most preferably at least about 90% oleic content) are especially preferred as starting materials. Examples include high-oleic sunflower and rapeseed/canola oil. In addition, a high-oleic methyl ester fraction derived from either palm kernel oil or tallow is acceptable. It is to be understood that such oils typically will contain some levels of impurities, including some fatty acid impurities that may be converted to sarcosinate compounds by this synthesis method. For example, commodity canola/rapeseed oil may comprise a majority of oleic acid, and a mixture of fatty acid impurities such as palmitic, stearic, linoleic, linolenic and/or eicosenoic acid, some or all of which are converted to the sarcosinate by this reaction method. If desired for formulation purposes, some or all of such impurity materials may be excluded from the starting oil before preparing the oleoyl sarcosinate to be used in the present compositions. Finally, sarcosine remaining in the reaction mixture can be converted to an amide by addition of maleic or acetic anhydride to the mixture, thereby minimizing the sarcosine content and any potential for formation of undesired nitrogen-containing impurities. The synthesis of oleoyl sarcosinate may be carried out as follows to prepare the sodium oleoyl sarcosinate. Synthesis of Oleoyl Amide of Sarcosine Sodium Salt - A 2 L, 3 -neck, round bottom flask is fitted with thermometer, Dean-Stark trap with condenser, mechanical stirring, and a gas inlet adapter through which nitrogen is passed over the reaction mixture. The reaction vessel is charged with sarcosine (43.3 g, 0.476 mol), sodium methoxide 25% in_ methanol (97.7 g, 0.452 mol), and methanol (400 mL). The reaction is refluxed 15 min to neutralize the sarcosine and then methyl ester derived from Cargill regular high-oleyl sunflower oil (148.25 g, 0.5 mol) is added. After the methanol is removed with the Dean- Stark trap, reaction mixture is heated to 170°C for 1 hr to drive off any water. The reaction is initiated by the addition of sodium methoxide 25% in methanol (15.4 g, 0.0714 mol). Reaction is kept at 170°C for 2.5 hr during which methanol is collected in the Dean-Stark trap. The reaction is allowed to cool slightly and then methanol (200 g) is added. Maleic anhydride (9.43 g, 0.095 mol) is added to the methanol solution and the reaction is stirred at 60°C for 0.5 hr. Then most of the methanol is removed by rotary evaporation and acetone (2 L) is added to precipitate the product. The product is collected by suction filtration and allowed to air dry to give an off-white solid. Analysis of the reaction mixture by GC indicates the majority of the product is oleoyl sarcosinate, with minor amounts of the following impurities: sarcosine, oleic acid, and the sarcosinates derived from palmitic acid, stearic acid, and linoleic acid. Surfactant System Nonlimiting examples of the preferred surfactants useful in the surfactant system include the conventional primary, branched-chain and random C10- 20 a ^ sulfates ("AS"), the C10- 18 secondary (2,3) alkyl sulfates of the formula CH3(CH2) x (CHOSO 3 " M + ) CH3 and CH3 (CH 2 ) y (CHOSO 3 " M + ) CH 2 CH 3 where x and (y + 1) are integers of at least about 7, preferably at least about 9, and M is a water-solubilizing cation, especially sodium, unsaturated sulfates such as oleyl sulfate, and the C jo-C j alkyl alkoxy sulfates ("AE X S"; especially x up to about 7 EO ethoxy sulfates). Optionally, other surfactants may be useful in the composition of the invention and include C\ j-Cjg alkyl benzene sulfonates ("LAS") and CjQ-Ci alkyl alkoxy carboxylates (especially the EO 1-5 ethoxycarboxylates), the C j Q_ 18 glycerol ethers, the Cjo-Cjg alkyl polyglycosides and their corresponding sulfated polyglycosides, and Cl2" l8 alpha-sulfonated fatty acid esters. If desired, the conventional nonionic and amphoteric surfactants such as the C^-Cjg alkyl ethoxylates ("AE") including the so- called narrow peaked alkyl ethoxylates and Cg-Ci2 alkyl phenol alkoxylates (especially ethoxylates and mixed ethoxy/propoxy), Cι 2 -Cjg betaines and sulfobetaines ("sultaines"), Cio-Cjg amine oxides, and the like, can also be included in the overall compositions. The Cjo- jg N-alkyl polyhydroxy fatty acid amides can also be used. Typical examples include the C^-C j N-methylglucamides. See WO 9,206, 154. Other sugar-derived surfactants include the N-alkoxy polyhydroxy fatty acid amides, such as C i Q- 18 N-(3 -methoxypropyl) glucamide. The N-propyl through N-hexyl C \ 2 -C i g glucamides can be used for low sudsing. Cι o-C 2 fj conventional soaps may also be used. If high sudsing is desired, the branched-chain C IQ-C \ soaps may be used. Mixtures of anionic and nonionic surfactants are especially useful. Other conventional useful surfactants are listed in standard texts. Adjunct Ingredients The compositions herein can optionally include one or more other detergent adjunct materials or other materials for assisting or enhancing cleaning performance, treatment of the substrate to be cleaned, or to modify the aesthetics of the detergent composition (e.g., colorants, dyes, perfumes, etc.). The following are illustrative examples of such adjunct materials. Detersive Builder - 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 about 1% 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 SiO 2 :Na 2 O ratio in the range 1 :1 to 3.2: 1 and layered 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 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-Na 2 Siθ5 moφhology 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 NaMSi x O 2x +ι yH 2 O 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-Na 2 Siθ5 (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 include those having the empirical formula: z n [(AlO 2 ) 2 (Siθ2)y] * xH2θ 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 about 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 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. Patent 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: Na 12 [(AlO 2 )i2(SiO 2 )i2] xH2O 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 puφoses 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. Patent 3,128,287, issued April 7, 1964, and Lamberti et al, U.S. Patent 3,635,830, issued January 18, 1972. See also "TMS/TDS" builders of U.S. Patent 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. Patents 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 -l i¬ as mellitic acid, 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 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-l,6-hexanedioates and the related compounds disclosed in U.S. Patent 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: 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. Patent 4,144,226, Crutchfield et al, issued March 13, 1979 and in U.S. Patent 3,308,067, Diehl, issued March 7, 1967. See also Diehl U.S. Patent 3,723,322. Fatty acids, e.g., C12- 18 monocarboxylic acids such as oleic acid and/or its salts, can also be incoφorated 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. Enzymes - Enzymes can be included in the formulations herein for a wide variety of fabric laundering puφoses, including removal of protein-based, carbohydrate-based, or triglyceride-based stains, for example, and for the prevention of refugee dye transfer, and for fabric restoration. The enzymes to be incoφorated include proteases, amylases, lipases, cellulases, and peroxidases, as well as mixtures thereof. Other types of enzymes may also be included. They may be of any suitable origin, such as vegetable, animal, bacterial, fungal and yeast origin. However, their choice is governed by several factors such as pH-activity and/or stability optima, thermostability, stability versus active detergents, builders and so on. In this respect bacterial or fungal enzymes are preferred, such as bacterial amylases and proteases, and fungal cellulases. Enzymes are normally incorporated at levels sufficient to provide up to about 5 mg by weight, more typically about 0.001 mg to about 3 mg, of active enzyme per gram of the composition. Stated otherwise, the compositions herein will typically comprise from about 0.001% to about 5%, preferably 0.01%-2% by weight of a commercial enzyme preparation. Protease enzymes are usually present in such commercial preparations at levels sufficient to provide from 0.005 to 0.1 Anson units (AU) of activity per gram of composition. Suitable examples of proteases are the subtilisins which are obtained from particular strains of B. subtilis and B. licheniforms. Another suitable protease is obtained from a strain of Bacillus, having maximum activity throughout the pH range of 8-12, developed and sold by Novo Industries A/S under the registered trade name ESPERASE. The preparation of this enzyme and analogous enzymes is described in British Patent Specification No. 1,243,784 of Novo. Proteolytic enzymes suitable for removing protein- based stains that are commercially available include those sold under the tradenames ALCALASE and SAVINASE by Novo Industries A/S (Denmark) and MAXATASE by International Bio-Synthetics, Inc. (The Netherlands). Other proteases include Protease A (see European Patent Application 130,756, published January 9, 1985); Protease B (see European Patent Application Serial No. 87303761.8, filed April 28, 1987, and European Patent Application 130,756, Bott et al, published January 9, 1985); and proteases made by Genencor International, Inc., according to one or more of the following patents: Caldwell et al, U.S. Patent Nos. 5,185,258, 5,204,015 and 5,244,791. Most preferred is what is called herein "Protease C", which is a variant of an alkaline serine protease from Bacillus, particularly Bacillus lentus. in which arginine replaced lysine at position 27, tyrosine replaced valine at position 104, serine replaced asparagine at position 123, and alanine replaced threonine at position 274. Protease C is described in EP 90915958:4; U.S. Patent No. 5,185,250; and U.S. Patent No. 5,204,015. Also preferred are protease which are described in copending application U.S. Serial No. 08/136,797, entitled Protease-containing Cleaning Compositions and copending Application U.S. Serial No. 08/136,626, entitled Bleaching Compositions Comprising Protease Enzymes, which are incorporated herein by reference. Genetically modified variants, particularly of Protease C, are also included herein. Amylases include, for example, α-amylases described in British Patent Specification No. 1,296,839 (Novo), RAPIDASE, International Bio-Synthetics, Inc. and TERMAMYL, Novo Industries. The cellulase usable in the present invention include both bacterial or fungal cellulase. Preferably, they will have a pH optimum of between 5 and 9.5. Suitable cellulases are disclosed in U.S. Patent 4,435,307, Barbesgoard et al, issued March 6, 1984, which discloses fungal cellulase produced from Humicola insolens and Humicola strain DSM1800 or a cellulase 212-producing fungus belonging to the genus Aeromonas, and cellulase extracted 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 (Novo) is especially useful. Suitable lipase enzymes for detergent usage include those produced by microorganisms of the Pseudomonas group, such as Pseudomonas stutzeri ATCC 19.154, as disclosed in British Patent 1,372,034. See also lipases in Japanese Patent Application 53,20487, laid open to public inspection on February 24, 1978. This lipase is available from Amano Pharmaceutical Co. Ltd., Nagoya, Japan, under the trade name Lipase P "Amano," hereinafter referred to as "Amano-P." Other commercial lipases include Amano-CES, lipases ex Chromobacter viscosum, e.g. Chromobacter viscosum var. lipolyticum NRRLB 3673, commercially available from Toyo Jozo Co., Tagata, Japan; and further Chromobacter viscosum lipases from U.S. Biochemical Coφ., U.S.A. and Disoynth Co., The Netherlands, and lipases ex Pseudomonas gladioli. The LIPOLASE enzyme derived from Humicola lanuginosa and commercially available from Novo (see also EPO 341,947) is a preferred lipase for use herein. Peroxidase enzymes are used in combination with oxygen sources, e.g., percarbonate, perborate, persulfate, hydrogen peroxide, etc. They are used for "solution bleaching," i.e. to prevent transfer of dyes or pigments removed from substrates during wash operations to other substrates in the wash solution. Peroxidase enzymes are known in the art, and include, for example, horseradish peroxidase, ligninase, and haloperoxidase such as chloro- and bromo-peroxidase. Peroxidase-containing detergent compositions are disclosed, for example, in PCT International Application WO 89/099813, published October 19, 1989, by O. Kirk, assigned to Novo Industries A/S. It may be desired to use, in combination with these peroxidases, materials viewed as being peroxidase accelerators such as phenolsulfonate and/or phenothiazine. A wide range of enzyme materials and means for their incorporation into synthetic detergent compositions are also disclosed in U.S. Patent 3,553, 139, issued January 5, 1971 to McCarty et al. Enzymes are further disclosed in U.S. Patent 4, 101,457, Place et al, issued July 18, 1978, and in U.S. Patent 4,507,219, Hughes, issued March 26, 1985, both. Enzymes for use in detergents can be stabilized by various techniques. Enzyme stabilization techniques are disclosed and exemplified in U.S. Patent 3,600,319, issued August 17, 1971 to Gedge, et al, and European Patent Application Publication No. 0 199 405, Application No. 86200586.5, published October 29, 1986, Venegas. Enzyme stabilization systems are also described, for example, in U.S. Patent 3,519,570. Enzyme Stabilizers - The enzymes employed herein are stabilized by the presence of water-soluble sources of calcium and/or magnesium ions in the finished compositions which provide such ions to the enzymes. (Calcium ions are generally somewhat more effective than magnesium ions and are preferred herein if only one type of cation is being used.) Additional stability can be provided by the presence of various other art-disclosed stabilizers, especially borate species: see Severson, U.S. 4,537,706. Typical detergents, especially liquids, will comprise from about 1 to about 30, preferably from about 2 to about 20, more preferably from about 5 to about 15, and most preferably from about 8 to about 12, millimoles of calcium ion per liter of finished composition. This can vary somewhat, depending on the amount of enzyme present and its response to the calcium or magnesium ions. The level of calcium or magnesium ions should be selected so that there is always some minimum level available for the enzyme, after allowing for complexation with builders, fatty acids, etc., in the composition. Any water-soluble calcium or magnesium salt can be used as the source of calcium or magnesium ions, including, but not limited to, calcium chloride, calcium sulfate, calcium malate, calcium maleate, calcium hydroxide, calcium formate, and calcium acetate, and the corresponding magnesium salts. A small amount of calcium ion, generally from about 0.05 to about 0.4 millimoles per liter, is often also present in the composition due to calcium in the enzyme slurry and formula water. In solid detergent compositions the formulation may include a sufficient quantity of a water-soluble calcium ion source to provide such amounts in the laundry liquor. In the alternative, natural water hardness may suffice. It is to be understood that the foregoing levels of calcium and/or magnesium ions are sufficient to provide enzyme stability. More calcium and/or magnesium ions can be added to the compositions to provide an additional measure of grease removal performance. Accordingly, as a general proposition the compositions herein will typically comprise from about 0.05% to about 2% by weight of a water-soluble source of calcium or magnesium ions, or both. The amount can vary, of course, with the amount and type of enzyme employed in the composition. The compositions herein may also optionally, but preferably, contain various additional stabilizers, especially borate-type stabilizers. Typically, such stabilizers will be used at levels in the compositions from about 0.25% to about 10%, preferably from about 0.5% to about 5%>, more preferably from about 0.75% to about 3%, by weight of boric acid or other borate compound capable of forming boric acid in the composition (calculated on the basis of boric acid). Boric acid is preferred, although other compounds such as boric oxide, borax and other alkali metal borates (e.g., sodium ortho-, meta- and pyroborate, and sodium pentaborate) are suitable. Substituted boric acids (e.g., phenylboronic acid, butane boronic acid, and p-bromo phenylboronic acid) can also be used in place of boric acid. It is to be recognized that such materials may also be used in formulations as the sole stabilizer as well as being used in combination with added calcium and/or magnesium ions. Finally, it may be desired to add chlorine scavengers, especially to protease- containing compositions, to protect the enzymes from chlorine typically present in municipal water supplies. Such materials are described, for example, in U.S. Patent 4,810,413 to Pancheri et al. 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 about 1% to about 30%, more typically from about 5% to about 20%, of the detergent composition, especially for fabric laundering. If present, the amount of bleach activators will typically be from about 0.1% to about 60%, more typically from about 0.5% to about 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 puφoses 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. Patent 4,483,781, Hartman, issued November 20, 1984, U.S. Patent Application 740,446, Burns et al, filed June 3, 1985, European Patent Application 0, 133,354, Banks et al, published February 20, 1985, and U.S. Patent 4,412,934, Chung et al, issued November 1, 1983 Highly preferred bleaching agents also include 6-nonylamino-6-oxoperoxycaproic acid as described in U.S. Patent 4,634,551, issued January 6, 1987 to Burns et al.

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 about 500 micrometers to about 1,000 micrometers, not more than about 10% by weight of said particles being smaller than about 200 micrometers and not more than about 10% by weight of said particles being larger than about 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 nonlimiting examples of activators are disclosed in U.S. Patent 4,915,854, issued April 10, 1990 to Mao et al, and U.S. Patent 4,412,934. The nonanoyloxybenzene sulfonate (NOBS) 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: R 1 N(R 5 )C(O)R 2 C(O)L or R 1 C(O)N(R 5 )R 2 C(O)L wherein R is an alkyl group containing from about 6 to about 12 carbon atoms, R 2 is an alkylene containing from 1 to about 6 carbon atoms, R$ is H or alkyl, aryl, or alkaryl containing from about 1 to about 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 bleach 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)oxybenzenesulfonate, (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, issued October 30, 1990, incorporated herein by reference. 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 R^ is H or an alkyl, aryl, alkoxyaryl, or alkaryl group containing from 1 to about 12 carbon atoms.

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. Patent 4,033,718, issued July 5, 1977 to Holcombe et al. If used, detergent compositions will typically contain from about 0.025% to about 1.25%, by weight, of such bleaches, especially sulfonate zinc phthalocyanine.

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 about 0.1 ppm to about 700 ppm, more preferably from about 1 ppm to about 500 ppm, of the catalyst species in the laundry liquor. Polymeric Soil Release Agent - Any polymeric soil release agent known to those skilled in the art can optionally be employed in the compositions and processes of this invention. 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 washing and rinsing cycles and, thus, serve as an anchor for the hydrophilic segments. This can enable stains occurring subsequent to treatment with the soil release agent to be more easily cleaned in later washing procedures. The polymeric soil release agents useful herein especially include those soil release agents having: (a) one or more nonionic hydrophile components consisting essentially of (i) polyoxyethylene segments with a degree of polymerization of at least 2, or (ii) oxypropylene or polyoxypropylene segments with a degree of polymerization of from 2 to 10, wherein said hydrophile segment does not encompass any oxypropylene unit unless it is bonded to adjacent moieties at each end by ether linkages, or (iii) a mixture of oxyalkylene units comprising oxyethylene and from 1 to about 30 oxypropylene units wherein said mixture contains a sufficient amount of oxyethylene units such that the hydrophile component has hydrophilicity great enough to increase the hydrophilicity of conventional polyester synthetic fiber surfaces upon deposit of the soil release agent on such surface, said hydrophile segments preferably comprising at least about 25% oxyethylene units and more preferably, especially for such components having about 20 to 30 oxypropylene units, at least about 50% oxyethylene units; or (b) one or more hydrophobe components comprising (i) C3 oxyalkylene terephthalate segments, wherein, if said hydrophobe components also comprise oxyethylene terephthalate, the ratio of oxyethylene terephthalate:C3 oxyalkylene terephthalate units is about 2: 1 or lower, (ii) C4-C6 alkylene or oxy C4-C6 alkylene segments, or mixtures therein, (iii) poly (vinyl ester) segments, preferably polyvinyl acetate), having a degree of polymerization of at least 2, or (iv) C 1 -C4 alkyl ether or C4 hydroxyalkyl ether substituents, or mixtures therein, wherein said substituents are present in the form of C1 -C4 alkyl ether or C4 hydroxyalkyl ether cellulose derivatives, or mixtures therein, and such cellulose derivatives are amphiphilic, whereby they have a sufficient level of C \ -C4 alkyl ether and/or C4 hydroxyalkyl ether units to deposit upon conventional polyester synthetic fiber surfaces and retain a sufficient level of hydroxyls, once adhered to such conventional synthetic fiber surface, to increase fiber surface hydrophilicity, or a combination of (a) and (b). Typically, the polyoxyethylene segments of (a)(i) will have a degree of polymerization of from about 200, although higher levels can be used, preferably from 3 to about 150, more preferably from 6 to about 100.

Such chelating agents can be selected from the group consisting of amino carboxylates, amino phosphonates, polyfunctionally-substituted aromatic chelating agents and mixtures therein, all as hereinafter defined. Without intending to be bound by theory, it is believed that the benefit of these materials is due in part to their exceptional ability to remove iron and manganese ions from washing solutions by formation of soluble chelates. Amino carboxylates useful as optional chelating agents include ethyl enediaminetetracetates, N-hydroxyethylethylenediaminetriacetates, nitrilotriacetates, ethylenediamine tetraproprionates, triethylenetetraaminehexacetates, diethylenetriaminepentaacetates, and ethanoldiglycines, alkali metal, ammonium, and substituted ammonium salts therein and mixtures therein.

No. 3,929,107, Thompson, issued Nov. 11, 1975; the hydroxyalkyl starch ethers, starch esters, oxidized starches, dextrins and starch hydrolysates described in U.S. Pat No. 3,803,285, Jensen, issued Apr. 9, 1974; the carboxylated starches described in U.S. Pat. No. 3,629, 121, Eldib, issued Dec. 21, 1971; and the dextrin starches described in U.S. Pat. No. 4, 141,841, McDanald, issued Feb. 27, 1979; all incorporated herein by reference. Preferred cellulose-derived dispersant polymers are the carboxymethyl celluloses. Yet another group of acceptable dispersants are the organic dispersant polymers, such as polyaspartate. 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 puφoses 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. In compositions containing detergent builders, it is believed, though it is not intended to be limited by theory, that polymeric dispersing agents enhance overall detergent builder performance, especially zeolite and/or silicate builders, when used in combination with other builders (including lower molecular weight polycarboxylates) by crystal growth inhibition, particulate soil release peptization, and anti-redeposition. Dispersing agents such as polyaspartate preferably have a molecular weight (avg.) of about 10,000. Brightener - Any optical brighteners or other brightening or whitening agents known in the art can be incoφorated at levels typically from about 0.05% to about 1.2%, by weight, into the detergent compositions herein. Commercial optical brighteners which may be useful in the present invention can be classified into subgroups, which include, but are not necessarily limited to, derivatives of stilbene, pyrazoline, coumarin, carboxylic acid, methinecyanines, dibenzothiphene-5,5-dioxide, azoles, 5- and 6-membered-ring heterocycles, and other miscellaneous agents. Examples of such brighteners are disclosed in "The Production and Application of Fluorescent Brightening Agents", M. Zahradnik, Published by John Wiley & Sons, New York (1982). Specific examples of optical brighteners which are useful in the present compositions are those identified in U.S. Patent 4,790,856, issued to Wixon on December 13, 1988. These brighteners include the PHORWHITE series of brighteners from Verona. Other brighteners disclosed in this reference include: Tinopal UNPA, Tinopal CBS and Tinopal 5BM; available from Ciba-Geigy; Artie White CC and Artie White CWD, available from Hilton-Davis, located in Italy; the 2-(4-stryl-phenyl)-2H- napthol[l,2-d]triazoles; 4,4'-bis- (l,2,3-triazol-2-yl)-stil- benes; 4,4'-bis(stryl)bisphenyls; and the aminocoumarins. Specific examples of these brighteners include 4-methyl-7- diethyl- amino coumarin; l,2-bis(-venzimidazol-2-yl)ethylene; 1,3-diphenyl-phrazolines; 2,5-bis(benzoxazol-2-yl)thiophene; 2-stryl-napth-[l,2-d]oxazole; and 2-(stilbene-4-yl)- 2H-naphtho- [l,2-d]triazole. See also U.S. Patent 3,646,015, issued February 29, 1972 to Hamilton. Anionic brighteners are preferred herein. Suds Suppressors - Compounds for reducing or suppressing the formation of suds can be incorporated into the compositions of the present invention. Suds suppression can be of particular importance in the so-called "high concentration cleaning process" as described in U.S. 4,489,455 and 4,489,574 and in front-loading European-style washing machines. A wide variety of materials may be used as suds suppressors, and suds suppressors are well known to those skilled in the art. See, for example, Kirk Othmer Encyclopedia of Chemical Technology, Third Edition, Volume 7, pages 430-447 (John Wiley & Sons, Inc., 1979). One category of suds suppressor of particular interest encompasses monocarboxylic fatty acid and soluble salts therein. See U.S. Patent 2,954,347, issued September 27, 1960 to Wayne St. John. The monocarboxylic fatty acids and salts thereof used as suds suppressor typically have hydrocarbyl chains of 10 to about 24 carbon atoms, preferably 12 to 18 carbon atoms. Suitable salts include the alkali metal salts such as sodium, potassium, and lithium salts, and ammonium and alkanolammonium salts. The detergent compositions herein may also contain non-surfactant suds suppressors. These include, for example: high molecular weight hydrocarbons such as paraffin, fatty acid esters (e.g., fatty acid triglycerides), fatty acid esters of monovalent alcohols, aliphatic C18-C40 ketones (e.g., stearone), etc. Other suds inhibitors include N- alkylated amino triazines such as tri- to hexa-alkylmelamines or di- to tetra-alkyldiamine chlortriazines formed as products of cyanuric chloride with two or three moles of a primary or secondary amine containing 1 to 24 carbon atoms, propylene oxide, and monostearyl phosphates such as monostearyl alcohol phosphate ester and monostearyl di- alkali metal (e.g., K, Na, and Li) phosphates and phosphate esters. The hydrocarbons such as paraffin and haloparaffin can be utilized in liquid form. The liquid hydrocarbons will be liquid at room temperature and atmospheric pressure, and will have a pour point in the range of about -40°C and about 50°C, and a minimum boiling point not less than about 110°C (atmospheric pressure). It is also known to utilize waxy hydrocarbons, preferably having a melting point below about 100°C. The hydrocarbons constitute a preferred category of suds suppressor for detergent compositions. Hydrocarbon suds suppressors are described, for example, in U.S. Patent 4,265,779, issued May 5, 1981 to Gandolfo et al. The hydrocarbons, thus, include aliphatic, alicyclic, aromatic, and heterocyclic saturated or unsaturated hydrocarbons having from about 12 to about 70 carbon atoms. The term "paraffin," as used in this suds suppressor discussion, is intended to include mixtures of true paraffins and cyclic hydrocarbons. Another preferred category of non-surfactant suds suppressors comprises silicone suds suppressors. This category includes the use of polyorganosiloxane oils, such as polydimethylsiloxane, dispersions or emulsions of polyorganosiloxane oils or resins, and combinations of polyorganosiloxane with silica particles wherein the polyorganosiloxane is chemisorbed or fused onto the silica. Silicone suds suppressors are well known in the art and are, for example, disclosed in U.S. Patent 4,265,779, issued May 5, 1981 to Gandolfo et al and European Patent Application No. 89307851.9, published February 7, 1990, by Starch, M. S. Other silicone suds suppressors are disclosed in U.S. Patent 3,455,839 which relates to compositions and processes for defoaming aqueous solutions by incorporating therein small amounts of polydimethylsiloxane fluids. Mixtures of silicone and silanated silica are described, for instance, in German Patent Application DOS 2,124,526. Silicone defoamers and suds controlling agents in granular detergent compositions are disclosed in U.S. Patent 3,933,672, Bartolotta et al, and in U.S. Patent 4,652,392, Baginski et al, issued March 24, 1987. An exemplary silicone based suds suppressor for use herein is a suds suppressing amount of a suds controlling agent consisting essentially of: (i) polydimethylsiloxane fluid having a viscosity of from about 20 cs. to about 1,500 cs. at 25°C; (ii) from about 5 to about 50 parts per 100 parts by weight of (i) of siloxane resin composed of (CH3)3SiOι/ 2 units of SiO 2 units in a ratio of from (CH3)3 SiOιy 2 units and to SiO 2 units of from about 0.6: 1 to about 1.2: 1 ; and (iii) from about 1 to about 20 parts per 100 parts by weight of (i) of a solid silica gel. In the preferred silicone suds suppressor used herein, the solvent for a continuous phase is made up of certain polyethylene glycols or polyethylene-polypropylene glycol copolymers or mixtures thereof (preferred), or polypropylene glycol. The primary silicone suds suppressor is branched/crosslinked and preferably not linear. To illustrate this point further, typical laundry detergent compositions with controlled suds will optionally comprise from about 0.001 to about 1, preferably from about 0.01 to about 0.7, most preferably from about 0.05 to about 0.5, weight % of said silicone suds suppressor, which comprises (1) a nonaqueous emulsion of a primary antifoam agent which is a mixture of (a) a polyorganosiloxane, (b) a resinous siloxane or a silicone resin-producing silicone compound, (c) a finely divided filler material, and (d) a catalyst to promote the reaction of mixture components (a), (b) and (c), to form silanolates; (2) at least one nonionic silicone surfactant; and (3) polyethylene glycol or a copolymer of polyethylene-polypropylene glycol having a solubility in water at room temperature of more than about 2 weight %; and without polypropylene glycol. See also U.S. Patents 4,978,471, Starch, issued December 18, 1990, and 4,983,316, Starch, issued January 8, 1991, 5,288,431, Huber et al., issued February 22, 1994, and U.S. Patents 4,639,489 and 4,749,740, Aizawa et al at column 1, line 46 through column 4, line 35. The silicone suds suppressor herein preferably comprises polyethylene glycol and a copolymer of polyethylene glycol/polypropylene glycol, all having an average molecular weight of less than about 1,000, preferably between about 100 and 800. The polyethylene glycol and polyethylene/polypropylene copolymers herein have a solubility in water at room temperature of more than about 2 weight %, preferably more than about 5 weight %. The preferred solvent herein is polyethylene glycol having an average molecular weight of less than about 1,000, more preferably between about 100 and 800, most preferably between 200 and 400, and a copolymer of polyethylene glycol/polypropylene glycol, preferably PPG 200/PEG 300. Preferred is a weight ratio of between about 1 : 1 and 1:10, most preferably between 1 :3 and 1 :6, of polyethylene glycol: copolymer of polyethylene-polypropylene glycol. The preferred silicone suds suppressors used herein do not contain polypropylene glycol, particularly of 4,000 molecular weight. They also preferably do not contain block copolymers of ethylene oxide and propylene oxide, like PLURONIC L101. Other suds suppressors useful herein comprise the secondary alcohols (e.g., 2- alkyl alkanols) and mixtures of such alcohols with silicone oils, such as the silicones disclosed in U.S. 4,798,679, 4,075,118 and EP 150,872. The secondary alcohols include the C6-C j 6 alkyl alcohols having a Cj-Cig chain. A preferred alcohol is 2-butyl octanol, which is available from Condea under the trademark ISOFOL 12. Mixtures of secondary alcohols are available under the trademark ISALCHEM 123 from Enichem. Mixed suds suppressors typically comprise mixtures of alcohol + silicone at a weight ratio of 1 :5 to 5: 1. For any detergent compositions to be used in automatic laundry washing machines, suds should not form to the extent that they overflow the washing machine. Suds suppressors, when utilized, are preferably present in a "suds suppressing amount. By "suds suppressing amount" is meant that the formulator of the composition can select an amount of this suds controlling agent that will sufficiently control the suds to result in a low-sudsing laundry detergent for use in automatic laundry washing machines. The compositions herein will generally comprise from 0% to about 5% of suds suppressor. When utilized as suds suppressors, monocarboxylic fatty acids, and salts therein, will be present typically in amounts up to about 5%, by weight, of the detergent composition. Preferably, from about 0.5% to about 3% of fatty monocarboxylate suds suppressor is utilized. Silicone suds suppressors are typically utilized in amounts up to about 2.0%), by weight, of the detergent composition, although higher amounts may be used. This upper limit is practical in nature, due primarily to concern with keeping costs minimized and effectiveness of lower amounts for effectively controlling sudsing. Preferably from about 0.01%) to about 1% of silicone suds suppressor is used, more preferably from about 0.25% to about 0.5%. As used herein, these weight percentage values include any silica that may be utilized in combination with polyorganosiloxane, as well as any adjunct materials that may be utilized. Monostearyl phosphate suds suppressors are generally utilized in amounts ranging from about 0.1% to about 2%, by weight, of the composition. Hydrocarbon suds suppressors are typically utilized in amounts ranging from about 0.01% to about 5.0%, although higher levels can be used. The alcohol suds suppressors are typically used at 0.2%-3% by weight of the finished compositions. Fabric Softeners - Various through-the-wash fabric softeners, especially the impalpable smectite clays of U.S. Patent 4,062,647, Storm and Nirschl, issued December 13, 1977, as well as other softener clays known in the art, can optionally be used typically at levels of from about 0.5% to about 10%> by weight in the present compositions to provide fabric softener benefits concurrently with fabric cleaning. Clay softeners can be used in combination with amine and cationic softeners as disclosed, for example, in U.S. Patent 4,375,416, Crisp et al, March 1, 1983 and U.S. Patent 4,291,071, Harris et al, issued September 22, 1981. D y e Transfer Inhibiting Agents - The compositions of the present invention may also include one or more materials effective for inhibiting the transfer of dyes from one fabric to another during the cleaning process. Generally, such dye transfer inhibiting agents include polyvinyl pyrrolidone polymers, polyamine N-oxide polymers, copolymers of N-vinylpyrrolidone and N-vinylimidazole, manganese phthalocyanine, peroxidases, and mixtures thereof. If used, these agents typically comprise from about 0.01% to about 10%) by weight of the composition, preferably from about 0.01% to about 5%, and more preferably from about 0.05% to about 2%. More specifically, the polyamine N-oxide polymers preferred for use herein contain units having the following structural formula: R-A x -P; wherein P is a polymerizable unit to which an N-O group can be attached or the N-O group can form 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(O)O-, -S-, -O-, -N=; x is 0 or 1; and R is aliphatic, ethoxylated aliphatics, aromatics, 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 wherein R is a heterocyclic group such as pyridine, pyrrole, imidazole, pyrrolidine, piperidine and derivatives thereof. The N-O group can be represented by the following general structures: wherein R\, R 2 , 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 form part of any of the aforementioned groups. The amine oxide unit of the polyamine N-oxides has a pKa <10, preferably pKa <7, more preferred pKa <6. Any polymer backbone can be used as long as the amine oxide polymer formed is water-soluble and has dye transfer inhibiting properties. Examples of suitable polymeric backbones are polyvinyls, polyalkylenes, polyesters, polyethers, polyamide, polyimides, polyacrylates and mixtures thereof. These polymers include random or block copolymers where one monomer type is an amine N-oxide and the other monomer type is an N-oxide. The amine N-oxide polymers typically have a ratio of amine to the amine N-oxide 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. The polyamine 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; more preferred 1,000 to 500,000; most preferred 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-vinylpyridine-N-oxide) which as an average molecular weight of about 50,000 and an amine to amine N-oxide ratio of about 1 :4. Copolymers of N-vinylpyrrolidone and N-vinylimidazole polymers (referred to as a class as "PVPVI") are also preferred for use herein. Preferably the PVPVI has an average molecular weight range from 5,000 to 1,000,000, more preferably from 5,000 to 200,000, and most preferably from 10,000 to 20,000. (The average molecular weight range is determined by light scattering as described in Barth, et al., Chemical Analysis, Vol 1 13. "Modern Methods of Polymer Characterization", the disclosures of which are incoφorated herein by reference.) The PVPVI copolymers typically have a molar ratio of N-vinylimidazole to N-vinylpyrrolidone from 1: 1 to 0.2: 1, more 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 present invention compositions also may employ a polyvinylpyrrolidone ("PVP") having an average molecular weight of from about 5,000 to about 400,000, preferably from about 5,000 to about 200,000, and more preferably from about 5,000 to about 50,000. PVP's are known to persons skilled in the detergent field; see, for example, EP-A-262,897 and EP-A-256,696, incoφorated herein by reference. Compositions containing PVP can also contain polyethylene glycol ("PEG") having an average molecular weight 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 ppm basis delivered in wash solutions is from about 2:1 to about 50:1, and more preferably from about 3:1 to about 10:1. The detergent compositions herein may also optionally contain from about 0.005% to 5% by weight of certain types of hydrophilic optical brighteners which also provide a dye transfer inhibition action. If used, the compositions herein will preferably comprise from about 0.01%> to 1% by weight of such optical brighteners. The hydrophilic optical brighteners useful in the present invention are those having the structural formula: wherein R\ 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, morphilino, chloro and amino; and M is a salt-forming cation such as sodium or potassium. When in the above formula, R\ is anilino, R 2 is N-2-bis-hydroxyethyl and M is a cation such as sodium, the brightener is 4,4',-bis[(4-anilino-6-(N-2-bis-hydroxyethyl)-s- triazine-2-yl)amino]-2,2'-stilbenedisulfonic acid and disodium salt. This particular brightener species is commercially marketed under the tradename Tinopal-UNPA-GX by Ciba-Geigy Corporation. Tinopal-UNPA-GX is the preferred hydrophilic optical brightener useful in the detergent compositions herein. When in the above formula, R\ is anilino, R 2 is N-2-hydroxyethyl-N-2- methylamino and M is a cation such as sodium, the brightener is 4,4'-bis[(4-anilino-6-(N- 2-hydroxyethyl-N-methylamino)-s-triazine-2-yl)amino]2,2'-stilbenedisulfonic acid disodium salt. This particular brightener species is commercially marketed under the tradename Tinopal 5BM-GX by Ciba-Geigy Coφoration. When in the above formula, R\ is anilino, R 2 is moφhilino and M is a cation such as sodium, the brightener is 4,4'-bis[(4-anilino-6-moφhilino-s-triazine-2-yl)amino]2,2'- stilbenedisulfonic acid, sodium salt. This particular brightener species is commercially marketed under the tradename Tinopal AMS-GX by Ciba Geigy Coφoration. The specific optical brightener species selected for use in the present invention provide especially effective dye transfer inhibition performance benefits when used in combination with the selected polymeric dye transfer inhibiting agents hereinbefore described. The combination of such selected polymeric materials (e.g., PVNO and/or PVPVI) with such selected optical brighteners (e.g., Tinopal UNPA-GX, Tinopal 5BM- GX and/or Tinopal AMS-GX) provides significantly better dye transfer inhibition in aqueous wash solutions than does either of these two detergent composition components when used alone. Without being bound by theory, it is believed that such brighteners work this way because they have high affinity for fabrics in the wash solution and therefore deposit relatively quick on these fabrics. The extent to which brighteners deposit on fabrics in the wash solution can be defined by a parameter called the "exhaustion coefficient". The exhaustion coefficient is in general as the ratio of a) the brightener material deposited on fabric to b) the initial brightener concentration in the wash liquor. Brighteners with relatively high exhaustion coefficients are the most suitable for inhibiting dye transfer in the context of the present invention. Of course, it will be appreciated that other, conventional optical brightener types of compounds can optionally be used in the present compositions to provide conventional fabric "brightness" benefits, rather than a true dye transfer inhibiting effect. Such usage is conventional and well-known to detergent formulations. Other Ingredients - A wide variety of other ingredients useful in detergent compositions can be included in the compositions herein, including other active ingredients, carriers, hydrotropes, processing aids, dyes or pigments, solid fillers for bar compositions, etc. If high sudsing is desired, suds boosters such as the Ci Q-Cjg alkanolamides can be incorporated into the compositions, typically at 1%-10% levels. The C10-C14 monoethanol and diethanol amides illustrate a typical class of such suds boosters. Use of such suds boosters with high sudsing adjunct surfactants such as the amine oxides, betaines and sultaines noted above is also advantageous. If desired, soluble magnesium salts such as MgCl 2 , MgSO4, and the like, can be added at levels of, typically, 0.1%-2%, to provide additional suds and to enhance grease removal performance. Various detersive ingredients employed in the present compositions optionally can be further stabilized by absorbing said ingredients onto a porous hydrophobic substrate, then coating said substrate with a hydrophobic coating. Preferably, the detersive ingredient is admixed with a surfactant before being absorbed into the porous substrate. In use, the detersive ingredient is released from the substrate into the aqueous washing liquor, where it performs its intended detersive function. To illustrate this technique in more detail, a porous hydrophobic silica (trademark SIPERNAT D10, DeGussa) is admixed with a proteolytic enzyme solution containing 3%-5% of C 3_i5 ethoxylated alcohol (EO 7) nonionic surfactant. Typically, the enzyme/surfactant solution is 2.5 X the weight of silica. The resulting powder is dispersed with stirring in silicone oil (various silicone oil viscosities in the range of 500- 12,500 can be used). The resulting silicone oil dispersion is emulsified or otherwise added to the final detergent matrix. By this means, ingredients such as the aforementioned enzymes, bleaches, bleach activators, bleach catalysts, photoactivators, dyes, fluorescers, fabric conditioners and hydrolyzable surfactants can be "protected" for use in detergents. 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 about 6.5 and about 1 1, preferably between about 7.5 and 10.5. Laundry products are typically at pH 9- 1 1. 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. Agglomeration Process The following describes exemplifies the agglomeration process by which the detergent composition of the invention can be produced. The parameters noted herein are exemplary only and should not be considered as limiting in any way. Step A - Preparation of Surfactant Paste - The objective is to combine the surfactants and liquid in the compositions into a common mix in order to aid in surfactant solubilization and agglomeration. In this Step, the surfactants and other liquid components in the composition are mixed together in a Sigma Mixer at MO (60°C) at about 40 rpm to about 75 rpm for a period of from 15 minutes to about 30 minutes to provide a paste having the general consistency of 20,000-40,000 centipoise. Once thoroughly mixed, the paste is stored at MOT (60°C) until agglomeration Step (B) is ready to be conducted. Step B - Agglomeration of Powders with Surfactant Paste - The puφose of this Step is to transform the base formula ingredients into flowable detergent agglomerates having a mean particle size range of from about 800 microns to about 1600 microns. In this Step, the powders (including materials such as zeolite, citrate, citric acid builder, layered silicate builder (as SKS-6), sodium carbonate, ethylenediaminedisuccinate, magnesium sulfate and optical brightener) are charged into the Eirich Mixer (R-Series) and mixed briefly (ca. 5 seconds - 10 seconds) at about 1500 φm to about 3000 m in order to mix the various dry powders fully. The surfactant paste from Step A is then charged into the mixer and the mixing is continued at about 1500 rpm to about 3000 φm for a period from about 1 minute to about 10 minutes, preferably 1-3 minutes, at ambient temperature. The mixing is stopped when course agglomerates (average particle size 200-1600 microns) are formed. In large-scale, continuous production environments, mixing apparatus commercially available from Lόdige (CB and/or KM) can be used to transform the surfactant paste and powders into free-flowing detergent agglomerates. Step C - The puφose of this Step is to reduce the agglomerates' stickiness by removing/drying moisture and to aid in particle size reduction to the target particle size (in the mean particle size range from about 200 to about 1600 microns, as measured by sieve analysis). In this Step, the wet agglomerates are charged into a fluidized bed at an air stream temperature of from about 41°C to about 60°C and dried to a final moisture content of the particles from about 4% to about 10%. Step D - Coat Agglomerates and Add Free-Flow Aids - The objective in this Step is to achieve the final target agglomerate size range of from about 200 microns to about 1600 microns, and to admix materials which coat the agglomerates, reduce the caking/lumping tendency of the particles and help maintain acceptable flowability. In this Step, the dried agglomerates from Step C are charged into the Eirich Mixer (R-Series) and mixed at a rate of about 1500 rpm to about 3000 rpm while adding 2-6% Zeolite A (median particle size 2-5 μm) during the mixing. The mixing is continued until the desired median particle size is achieved (typically from about 5 seconds to about 45 seconds). At this point, from about 0.1% to about 1.5% by weight of precipitated silica (average particle size 1-3 microns) is added as a flow aid and the mixing is stopped. In order to make the present invention more readily understood, reference is made to the following examples, which are intended to be illustrative only and not intended to be limiting in scope. EXAMPLE I This example illustrates a detergent composition made in accordance with the invention. The relative proportions of the ingredients are set forth in Table I below.

A base formula of the starting liquids and powdered materials are combined via a variety of known processes including conventional spray drying techniques or agglomeration in apparatus such as powder mixers and fluid beds commercially available from Lόdige and Aeromatic, respectively. Agglomeration is especially suitable for preparing modern compact granular detergents and entails initially forming a surfactant paste using standard mixers, after which the paste is agglomerated into agglomerates and dried. Such processing techniques are well known in the art. The enzymes such as cellulases are dry mixed into the base formula and the perfumes used herein are subsequently sprayed onto the base formula so as to form the final granular detergent compositions exemplified herein. EXAMPLE π Several detergent compositions (B, C and D) are made in accordance with the agglomeration process described above. Compositions B and C are within the scope of the invention and composition D is outside of the invention and is presented for puφoses of comparison as described in Example III hereinafter.

The laundering solution is continuously agitated at a rate of 75 rpm and samples of the wash solution were taken at various time intervals as shown in Table III below. For purposes of illustrating the improved solubility of the detergent composition according to the invention, the amount of anionic (sulfated or sulfonated) surfactant in the laundering solution is determined by conducting the well known "catSO3" titration technique on the samples taken from individual wash solutions containing one of the tested compositions. In particular, the amount of anionic surfactant in the laundering solution is determined by filtering the samples through 0.45 nylon filter paper to remove the insolubles and thereafter, titrating the filtered solution to which anionic dyes (dimidium bromide) have been added with a cationic titrant such as Hyamine™ commercially available from Sigma Chemical Company. Accordingly, the relative amount of anionic surfactant dissolved in the wash solution can be determined. This technique is well known and others may be used if desired. The results are shown in Table III below.
