Description: DETERGENT COMPOSITIONS CONTAINING POLYHYDROXY FATTY ACID AMIDE AND ALKYL ESTER SULFONATE SURFACTANTS FIELD OF INVENTION This invention pertains to detergent compositions containing alkyl ester sulfonate surfactant having improved performance through the use of polyhydroxy fatty acid amide surfactant. BACKGROUND OF THE INVENTION The ability of detergent compositions to clean a large variety of soils and stains from the numerous types of fabrics present in the typical load of laundry, as well as cleaning of other surfaces (e.g., hard surfaces, hair, etc.) is of high importance in the evaluation of detergent performance. One type of surfactant which has been of value due to its good overall cleaning ability, particu¬ larly its excellent grease/oil cleaning performance over a wide temperature range (including relatively low temperatures) encom¬ passes the linear alkylbenzene sulfonates ("LAS"). Whereas LAS- containing surfactant systems have performed admirably, it would be desirable to provide surfactant systems which could provide comparable levels of overall cleaning ability, including grease/oil cleaning, over a wide range of temperature and materials, wherein the major surfactant ingredients utilized could viably be derived primarily or even entirely from natural, renewable, non-petroleum resources. In particular, since a significant portion of LAS is typically petroleum-derived, it would be desirable to reduce or even eliminate the content of LAS while still maintaining excellent overall cleaning ability. Conventional nonionic surfactants can provide generally accept¬ able cleaning, but typically require relatively long wash times, high wash temperatures, and high surfactant concentration to achieve effective grease/oil cleaning. One type of surfactant that has been proposed and that can be derived largely or entirely from renewable, non-petroleum raw materials, encompasses the alkyl ester sulfonates, such as but not limited to methyl ester sulfonates. However, these surfactants do not by themselves offer the desired levels of overall cleaning performance, especially in the area of grease/oil cleaning. Furth¬ ermore, even upon combination of alkyl ester sulfonates with conventional co-surfactants such as alkyl ethoxylates, the desired levels of cleaning performance for a broad range of wash conditions are difficult to obtain. . It has now been found that improved detersive surfactant systems containing alkyl ester sulfonate can be obtained through the use of such alkyl ester sulfonates in combination with certain polyhydroxy fatty acid amide surfactants. Furthermore, the polyhydroxy fatty acid amides can be derived mainly or entirely from natural, renewable, non- petroleum raw materials.

Z preferably will be derived from a reducing sugar in reductive amination reaction; more preferably Z is a glycityl. Suitable reducing sugars include glucose, fructose, maltose, lactose, galactose, mannose and xylose. As raw materials, high dextrose corn syrup, high fructose corn syrup, and high maltose corn syrup can be utilized as well as the individual sugars listed above. It should be understood that these corn syrups may yield a mix of sugar components for Z. Z preferably will be selected from the group consisting of -CH 2 -(.CH0H) n -CH 2 0H, -CH(CH 2 OH)-(CHOH) n -ι- CH 2 0H, -CH 2 -(CH0H)2-(CH0R')-(CH0H)-CH 2 0H, and alkoxylated deriva- tives thereof, where n is an integer from 3 to 5, inclusive, and R' is H or a cyclic or aliphatic monosaccharide. Most preferred are glycityls wherein n is 4, particularly -CH2-(CH0H)4-CH20H. In Formula (I), R 1 can be, for example, N-methyl, N-ethyl, N-propyl, N-isopropyl, N-butyl , N-2-hydroxy ethyl, or N-2-hydroxy propyl . R 2 -C0-N< can be, for example, cocamide, steara ide, oleamide, lauramide, myristamide, capricamide, palmitamide, tallowamide, etc. Z ccan be 1-deoxyglucityl , 2-deoxyfructityl, 1-deoxymaltityl , 1-deoxylactityl, 1-deoxygalactityl, 1-deoxymannityl , 1-deoxymalto- triotityl, etc. Methods for making polyhydroxy fatty acid amides are known in the art. In general, they can be made by reacting an alkyl amine with a reducing sugar in a reductive amination reaction to form a corresponding N-alkyl polyhydroxyamine, and then reacting the N-alkyl polyhydroxyamine with a fatty aliphatic ester or triglyceride in a condensation/amidation step to form the N-alkyl, N-polyhydroxy fatty acid amide product. Processes for making compositions containing polyhydroxy fatty acid amides are disclosed, for example, in G.B. Patent Specification 809,060, published February 18, 1959, by Thomas Hedley & Co., Ltd., U.S. Patent 2,965,576, issued December 20, 1960 to E. R. Wilson, and U.S. Patent 2,703,798, Anthony M. Schwartz, issued March 8, 1955, and U.S. Patent 1,985,424, issued December 25, 1934 to Piggott, each of which is incorporated herein by reference. In one process for producing N-alkyl or N-hydroxyalkyl, N-deoxyglycityl fatty acid amides wherein the glycityl component is derived from glucose and the N-alkyl or N-hydroxyalkyl functionality is N-methyl, N-ethyl , N-propyl, N-butyl, N-hydroxyethyl , or N-hydroxypropyl , the product is made by reacting N-alkyl- or N-hydroxyalkyl-glucamine with a fatty ester selected from fatty methyl esters, fatty ethyl esters, and fatty triglycerides in the presence of a catalyst selected from the group consisting of tri- lithium phosphate, trisodium phosphate, tripotassium phosphate, tetrasodium pyrophosphate, pentapotassium tripolyphosphate, lithium hydroxide, sodium hydroxide, potassium hydroxide, calcium hydroxide, lithium carbonate, sodium carbonate, potassium carbonate, disodium tartrate, dipotassium tartrate,' sodium potassium tartrate, trisodium citrate, tripotassium citrate, sodium basic silicates, potassium basic silicates, sodium basic aluminosilicates, and potassium basic aluminosilicates, and mixtures thereof. The amount of catalyst is preferably from about 0.5 mole % to about 50 mole %, more preferably from about 2.0 mole % to about 10 mole %, on an N-alkyl or N-hydroxyalkyl-glucamine molar basis. The reaction is preferably carried out at from about 138 β C to about 170°C for typically from about 20 to about 90 minutes. When triglycerides are utilized as the fatty ester, the reaction is also preferably carried out using from about 1 to about 10 weight % of a phase transfer agent, calculated on a weight percent basis of total reaction mixture, selected from saturated fatty alcohol polyethoxylates, alkylpolygly- cosides, linear glycamide surfactant, and mixtures thereof. Preferably, this process is carried out as follows: (a) preheating the fatty ester to about 138 β C to about 170 β C; (b) adding the N-alkyl or N-hydroxyalkyl glucamine to the heated fatty acid ester and mixing to the extent needed to form a two-phase liquid/liquid mixture; (c) mixing the catalyst into the reaction mixture; and (d) stirring for the specified reaction time. Also preferably, from about 2% to about 20% of preformed linear N-alkyl/N-hydroxyalkyl, N-linear glucosyl fatty acid amide product is added to the reaction mixture, by weight of the reactants, as the phase transfer agent if the fatty ester is a triglyceride. This seeds the reaction, thereby increasing reaction rate. A detailed experimental procedure is provided below. The polyhydroxy "fatty acid" amide materials used herein also offer the advantages to the detergent formulator that they can be prepared wholly or primarily from natural, renewable, non-petrochemical feedstocks and are degradable. They also exhibit low toxicity to aquatic life. It should be recognized that along with the polyhydroxy fatty acid amides of Formula (I), the processes used to produce them will also typically produce quantities of nonvolatile by-product such as esteramides and cyclic polyhydroxy fatty acid.amide. The level of these by-products will vary depending upon the particular reactants and process conditions. Preferably, the polyhydroxy fatty acid amide incorporated into the detergent compositions hereof will be provided in a form such that the polyhydroxy fatty acid amide- containing composition to be added to the detergent contains less than about 10%, preferably less than about 4%, of cyclic polyhydroxy fatty acid amide. The preferred processes described above are advantageous in that they can yield rather low levels of by-products, including such cyclic amide by-product. Alkyl Ester Sulfonate Surfactant The detergent compositions hereof will comprise at least about 1% alkyl ester sulfonate surfactant, weight basis based upon the total detergent composition, and will preferably comprise at least about 3%, more preferably from about 3% to about 50%, most preferably from about 3% to about 30%. The weight ratio of alkyl ester sulfonate to polyhydroxy fatty acid amide is preferably from about 1:10 to about 10:1, more preferably from about 1:5 to about 5:1, most preferably from about 1:3 to about 3:1. For laundry cleaning under typical top-loading automatic washing machine conditions wherein water temperature is no more than about 50 β C and detergent concentration in the wash water is from about 1000 to about 3000 ppm, a weight ratio of about 1.25:1 to about 1:1.25, especially about 1:1 is most preferred. Alkyl ester sulfonate surfactants are known to those in the art and are disclosed in the technical literature. For instance, linear esters of C8-C 0 carboxylic acids can be sulfonated with gaseous SO3 according to "The Journal of the American Oil Chemists Society," 52 (1975), pp. 323-329. Suitable starting materials would include natural fatty substances as derived from tallow, palm, and coconut oils, etc. The preferred alkyl ester sulfonate surfactant, especially for laundry applications, comprise alkyl ester sulfonate surfactants of the structural formula: 0 R3 - CH - C - OR 4 SO3M wherein R 3 is a C8-C20 hydrocarbyl, preferably an alkyl, or combination thereof, R 4 is a Ci-Cβ hydrocarbyl, preferably an alkyl, or combination thereof, and M is a water soluble salt-forming cation.

Exemplary, non-limiting classes of useful nonionic surfactants are listed below. 1. The polyethylene, polypropylene, and polybutylene oxide condensates of alkyl phenols. In general, the polyethylene oxide condensates are preferred. These compounds include the condensation products of alkyl phenols having an alkyl group containing from about 6 to about 12 carbon atoms in either a straight chain or branched chain configuration with the alkylene oxide. In a preferred embodiment, the ethylene oxide is present in an amount equal to from about 5 to about 25 moles of ethylene oxide per mole of alkyl phenol. Commercially available nonionic surfactants of this type include Igepal™ CO-630, marketed by the GAF Corporation; and Triton™ χ-45, X-114, X-100, and X-102, all marketed by the Rohm & Haas Company. These surfactants are commonly referred to as alkyl phenol alkoxylates, e.g., alkyl phenol ethoxylates. 2. The condensation products of aliphatic alcohols with from about 1 to about 25 moles of ethylene oxide. The alkyl chain of the aliphatic alcohol can either be straight or branched, primary or secondary, and generally contains from about 8 to about 22 carbon atoms. Particularly preferred are the condensation products of alcohols having an alkyl group containing from about 10 to about 20 carbon atoms with from about 2 to about 18 moles of ethylene oxide per mole of alcohol.

The hydrophobic portion of these compounds preferably has a molecular weight of from about 1500 to about 1800 and exhibits water insolubility. The addition of polyoxyethylene moieties to this hydrophobic portion tends to increase the water solubility of the molecule as a whole, and the liquid character of the product is retained up to the point where the polyoxyethylene content is about 50% of the total weight of the condensation product, which corresponds to condensation with up to about 40 moles of ethylene oxide. Examples of compounds of this type include certain of the commercially-available PluronicTM surfactants, marketed by BASF. 4.

See U.S. Patent No. 3,929,678 to Laughlin et a!., issued December 30, 1975 at column 19, line 38 through column 22, line 48 (herein incorporated by reference) for examples of zwitterionic surfactants. Ampholytic and zwitterionic surfactants are generally used in combination with one or more anionic and/or nonionic surfactants. Tertiary Surfactant System In a highly preferred detergent composition, alkyl ester sulfonate and polyhydroxy fatty acid amide surfactants are combined with an alkyl ethoxylate or alkyl polyglycoside (preferably an alkyl polyglucoside) nonionic auxiliary surfactant, or a mixture thereof. This combination can provide unexpectedly high levels of cleaning performance. In such preferred detergents, the alkyl ester sulfonate comprises at least about 40%, by weight, of the total amount of surfactant in the detergent composition, the level of polyhydroxy fatty acid amide is from about 1% to about 40%, preferably from about 3% to about 25%, and the polyhydroxy fatty acid amide to the preferred nonionic surfactants is from about 1:20 to about 20:1, preferably about 1:5 to about 10:1, more preferably from 1:1 to about 10:1.

It should be understood that other tertiary surfactant systems are not meant to be excluded from the scope of the present invention. Builders Detergent builders can optionally be included in the compositions hereof to assist in controlling mineral hardness. Inorganic as well as organic builders can be used. 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. Liquid formulations typically comprise from about 5% to about 50%, more typically about 5% to about 30%, by weight, of detergent builder. Granular formulations typically comprise from about 10% to about 80%, more typically from about 15% to about 50% by weight, of the detergent builder. Lower or higher levels of builder, however, are not meant to be excluded. Inorganic detergent builders include, but are not limited to, the alkali metal, ammonium and alkanolammonium salts of polyphos- phates (exemplified by the tripolyphosphates, pyrophosphates, and glassy polymeric meta-phosphates), phosphonates, phytic acid, silicates, carbonates (including bicarbonates and sesquicarbonates), sulphates, and aluminosilicates. Borate builders, as well as builders containing borate-forming materials that can produce borate under detergent storage or wash conditions (hereinafter collectively "borate builders"), can also be used. Preferably, non-borate builders are used in compositions of the invention intended for use at wash conditions less than about 50 β C, especially less than about 40 β C. Examples of silicate builders are the alkali metal silicates, particularly those having a Siθ2:Na2θ ratio in the range 1.6:1 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, incorporated herein by reference. However, other silicates may also be useful such as for example magnesium silicate, which can serve as a crispening agent in granular formulations, as a stabiliz- ing agent for oxygen bleaches, and as a component of suds control systems. Examples of carbonate builders are the alkaline earth and alkali metal carbonates, including sodium carbonate and sesquicar- bonate and mixtures thereof with ultra-fine calcium carbonate as disclosed in German Patent Application No. 2,321,001 published on November 15, 1973, the disclosure of which is incorporated herein by reference. Aluminosilicate builders are especially useful in the present invention. Aluminosilicate builders are of great importance in most currently marketed heavy duty granular detergent compositions, and can also be a significant builder ingredient in liquid detergent formulations. Aluminosilicate builders include those having the empirical formula: M z (zAlθ2-ySiθ2) wherein M is sodium, potassium, ammonium or substituted ammonium, z is from about 0.5 to about 2; and y is 1; this material having a magnesium ion exchange capacity of at least about 50 milligram equivalents of CaC03 hardness per gram of anhydrous aluminosilicate.

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, incorporated herein by reference. Preferred synthetic crystalline aluminosilicate ion exchange materials useful herein are available under the designations Zeolite A, Zeolite P (B), and Zeolite X. In an especially preferred embodiment, the crystalline aluminosilicate ion exchange material has the formula: Naι 2 [(A10 2 )l2(Siθ2)l2]-xH2θ wherein x is from about 20 to about 30, especially about 27.

Phosphonate builder salts of the aforementioned types are disclosed in U.S. Patent Nos. 3,159,581 and 3,213,030 issued December 1, 1964 and October 19, 1965, to Diehl; U.S. Patent No. 3,422,021 issued January 14, 1969, to Roy; and U.S. Patent Nos. 3,400,148 and 3,422,137 issued September 3, 1968, and January 14, 1969 to Quimby, said disclosures being incorporated herein by reference. Organic detergent builders suitable for the purposes of the present invention include, but are not restricted to, a wide variety of polycarboxylate compounds. As used herein, "polycarboxylate" refers to compounds having a plurality of carboxylate groups, preferably at least 3 carboxylates. Polycarboxylate builder can generally be added to the composition in acid form, but can also be added in the form of a neutralized salt. When utilized in salt form, alkali metals, such as sodium, potassium, and lithium, or alkanolammonium salts are preferred. Included among the polycarboxylate builders are a variety of categories of useful materials. One important category of polycarboxylate builders encompasses the ether polycarboxylates. A number of ether polycarboxylates have been disclosed for use as detergent builders. Examples of useful ether polycarboxylates include 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, both of which are incorporated herein by reference. A specific type of ether polycarboxylates useful as builders in the present invention also include those having the general formula: CH(A)(C00X)-CH(C00X)-0-CH(C00X)-CH(C00X)(B) wherein A is H or OH; B is H or -0-CH(C00X)-CH2(C00X) ; and X is H or a salt-forming cation. For example, if in the above general formula A and B are both H, then the compound is oxydissuccinic acid and its water-soluble salts. If A is OH and B is H, then the compound is tartrate monosuccinic acid (TMS) and its water-soluble salts. If A is H and B is -0-CH(C00X)-CH2(C00X), then the compound is tartrate disuccinic acid (TDS) and its water-soluble salts. Mixtures of these builders are especially preferred for use herein. Particu¬ larly preferred are mixtures of TMS and TDS in a weight ratio of TMS to TDS of from about 97:3 to about 20:80. These builders are disclosed in 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, all of which are incorporated herein by reference. Other useful detergency builders include the ether hydroxypoly- carboxylates represented by the structure: H0-[C(R)(COOM)-C(R)(COOM)-0] n -H wherein M is hydrogen or a cation wherein the resultant salt is water-soluble, preferably an alkali metal, ammonium or substituted ammonium cation, n is from about 2 to about 15 (preferably n is from about 2 to about 10, more preferably n averages from about 2 to about 4) and each R is the same or different and selected from hydrogen, C1-4 alkyl or C1-4 substituted alkyl (preferably R is hydrogen) . Still other ether polycarboxylates include copolymers of maleic anhydride with ethylene or vinyl methyl ether, 1, 3, 5-trihydroxy benzene-2, 4, 6-trisulphonic acid, and carboxymethyloxysuccinic acid. Organic polycarboxylate builders also include the various alkali metal, ammonium and substituted ammonium salts of polyacetic acids. 'Examples include the sodium, potassium, lithium, ammonium and substituted ammonium salts of ethylenediamine tetraacetic acid, and nitrilotriacetic acid. Also included are polycarboxylates such as mellitic acid, succinic acid, oxydisuccinic acid, poly aleic acid, benzene 1,3,5-tricarboxylic acid, and carboxymethyloxysuccinic acid, and soluble salts thereof. Citrate builders, e.g., citric acid and soluble salts thereof (particularly sodium salt), are polycarboxylate builders of particular importance for heavy duty liquid detergent formulations, but can also be used in granular compositions. Other carboxylate builders include the carboxylated carbohy¬ drates disclosed in U.S. Patent 3,723,322, Diehl, issued March 28, 1973, incorporated herein by reference. 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, incorporated herein by reference. Useful succinic acid builders include the C5-C20 alkyl succinic acids and salts thereof. A particularly preferred compound of this type is dodecenylsuccinic acid. Alkyl succinic acids typically are of the general formula R-CH(C00H)CH2(C00H) i.e., derivatives of succinic acid, wherein R is hydrocarbon, e.g., C10-C20 alkyl or alkenyl, preferably C12- 16 or wherein R may be substituted with hydroxyl, sulfo, sulfoxy or sulfone substituents, all as described in the above-mentioned patents. The succinate builders are preferably used in the form of their water-soluble salts, including the sodium, potassium, ammonium and alkanolammonium salts. Specific examples of succinate builders include: laurylsuccinate, yristylsuccinate, palmitylsuccinate, 2-dodecenyl- succinate (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. Examples of useful builders also include sodium and potassium carboxymethyloxymalonate, carboxymethyloxysuccinate, cis-cyclohex- ane-hexacarboxylate, cis-cyclopentane-tetracarboxylate, water- soluble polyacrylates (these polyacrylates having molecular weights to above about 2,000 can also be effecitvly utilized as dispers- ants), and the copolymers of aleic anhydride with vinyl methyl ether or ethylene. Other suitable polycarboxylates are the polyacetal carboxylates disclosed in U.S. Patent 4,144,226, Crutchfield et al . , issued March 13, 1979, incorporated herein by reference. These polyacetal carboxylates can be prepared by bringing together, under polymeriza¬ tion conditions, an ester of glyoxylic acid and a polymerization initiator. The resulting polyacetal carboxylate ester is then attached to chemically stable end groups to stabilize the polyacetal carboxylate against rapid depolymerization in alkaline solution, converted to the corresponding salt, and added to a surfactant. Polycarboxylate builders are also disclosed in U.S. Patent 3,308,067, Diehl, issued March 7, 1967, incorporated herein by reference. Such materials include the water-soluble salts of homo- and copolymers of aliphatic carboxylic acids such as maleic acid, itaconic acid, mesaconic acid, fumaric acid, aconitic acid, citraconic acid and methylenema!onic acid. Other organic builders known in the art can also be used. For example, monocarboxylic acids, and soluble salts thereof, having long chain hydrocarbyls can be utilized. These would include materials generally referred to as "soaps." Chain lengths of C10-C20 are typically utilized. The hydrocarbyls can be saturated or unsaturated. Enzymes Enzymes can be included in the detergent formulations for a variety of purposes including removal of protein-based, carbohydrate-based, or triglyceride-based stains, for example, and prevention of refugee dye transfer. The enzymes to be incorporated include proteases, amylases, Upases, peroxidases, and cellulases, as well as mixtures thereof. Other types of enzymes may also be used. 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. 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 ALCALASETM and SAVINASE™ by Novo Industries A/S (Denmark) and MAXATASE™ by International Bio-Synthetics, Inc. (The Netherlands). Of interest in the category of proteolytic enzymes, especially for liquid detergent compositions, are enzymes referred to herein as Protease A and Protease B. Protease A and methods for its preparation are described in European Patent Application 130,756, published January 9, 1985, incorporated herein by reference. Protease B is a proteolytic enzyme which differs from Protease A in that it has a leucine substituted for tyrosine in position 217 in its amino acid sequence. Protease B is described in European Patent Application Serial No. 87303761.8, filed April 28, 1987, incorporated herein by reference. Methods for preparation of Protease B are also disclosed in European Patent Application 130,756, Bott et al . , published January 9, 1985, incorporated herein by reference. Amylases include, for example, α-amylases obtained from a special strain of B.licheniforms, described in more detail in British patent specification No. 1,296,839 (Novo), previously incorporated herein by reference. A ylolytic proteins include, for example, RAPIDASETM, International Bio-Synthetics, Inc. and TERMAMYL™, Novo Industries. The cellulases 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, incorporated herein by reference, which discloses fungal cellulase produced from Humicola insolens. Suitable cellulases are also disclosed in GB-A-2.075.028; GB-A-2.095.275 and DE-0S-2.247.832. Examples of such cellulases are cellulases produced by a strain of Humicola insolens (Humicola grisea var. thermoidea), particularly the Humicola strain DSM 1800, and cellulases produced by a fungus of Bacillus N or a cellulase 212-producing fungus belonging to the genus Aeromonas, and cellulase extracted from the hepatopancreas of a marine mollusc (Dolabella Auricula Solander). 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 No. 1,372,034, incorporated herein by reference. Suitable upases include those which show a positive immunoligical cross-reaction with the antibody of the lipase, produced by the microorganism Pseudomonas fluorescens IAM 1057. This lipase and a method for its purification have been described in Japanese Patent Application No. 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." Such Upases of the present invention should show a positive immunological cross reaction with the Amano-P antibody, using the standard and well-known immunodiffusion procedure according to Ouchterlony (Acta. Med. Scan., 133, pages 76-79 (1950)). These Upases, and a method for their immunological cross-reaction with Amano-P, are also described in U.S. Patent 4,707,291, Thorn et al., issued November 17, 1987, incorporated herein by reference. Typical examples thereof are the Amano-P lipase, the lipase ex Pseudomonas fragi FERM P 1339 (available under the trade name Amano-B), lipase ex Psuedo onas m ' troreducens var. 'polyticum FERM P 1338 (available under the trade name Amano-CES), upases ex Chromobacter viscosu , e.g. Chromobacter viscosum var. h'polyticum NRRLB 3673, commercially available from Toyo Jozo Co., Tagata, Japan; and further Chromobacter viscosum upases from U.S. Biochemical Corp., U.S.A. and Disoynth Co., The Netherlands, and upases ex Pseudomonas gladioli . 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 0. Kirk, assigned to Novo Industries A/S, incorporated herein by reference. A wide range of enzyme materials and means for their incorporation into synthetic detergent granules is also disclosed in U.S. Patent 3,553,139, issued January 5, 1971 to McCarty et al . (incorporated herein by reference). Enzymes are further disclosed in U.S. Patent No. 4,101,457, Place et al., issued July 18, 1978, and in U.S. Patent 4,507,219, Hughes, issued March 26, 1985, both incorporated herein by reference. Enzyme materials useful for liquid detergent formulations, and their incorporation into such formulations, are disclosed in U.S. Patent 4,261,868, Hora et al., issued April 14, 1981, also incorporated herein by reference. Enzymes are normally incorporated at levels sufficient to provide up to about 5 mg by weight, more typically about 0.05 mg to about 3 mg, of active enzyme per gram of the composition. For granular detergents, the enzymes are preferably coated or prilled with additives inert toward the enzymes to minimize dust formation and improve storage stability. Techniques for accomplish¬ ing this are well known in the art. In liquid formulations, an enzyme stabilization system is preferably utilized. Enzyme stabilization techniques for aqueous detergent compositions are well known in the art. For example, one technique for enzyme stabilization in aqueous solutions involves the use of free calcium ions from sources such as calcium acetate, calcium formate, and calcium propionate. Calcium ions can be used in combination with short chain carboxylic acid salts, perferably formates. See, for example, U.S. Patent 4,318,818, Letton, et al . , issued March 9, 1982, incorporated herein by reference. It has also been proposed to use polyols like glycerol and sorbitol. Alkoxy-alcohols, dialkylglycoethers, mixtures of polyvalent alcohols with polyfunctional aliphatic amines (e.g., alkanolamines such as diethanolamine, triethanol mine, di-isopropanolamine, etc.), and boric acid or alkali metal borate. Enzyme stabilization techniques are additionally disclosed and exemplified in U.S. Patent 4,261,868, issued April 14, 1981 to Horn, et al., U. S. Patent 3,600,319, issued August 17, 1971 to Gedge, et al ., both incorporated herein by reference, and European Patent Application Publication No. 0 199 405, Application No. 86200586.5, published October 29, 1986, Venegas. Non-boric acid and borate stabilizers are preferred. Enzyme stabilization systems are also described, for example, in U.S. Patents 4,261,868, 3,600,319, and 3,519,570. Bleaching Compounds - Bleaching Agents and Bleach Activators The detergent compositions hereof may contain bleaching agents or bleaching compositions containing bleaching agent and one or more bleach activators. When present bleaching compounds will typically be present at levels of from about 1% to about 20%, more typically from about 1% to about 10%, of the detergent composition. In general, bleaching compounds are optional components in non-liquid formulations, e.g., granular detergents. 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. The bleaching agents used herein can be any of the bleaching agents useful for detergent compositions in textile cleaning, hard surface cleaning, or other cleaning purposes that are now known or become known. These include oxygen bleaches as well as other bleaching agents. For wash conditions below about 50 * C, especially below about 40'C, it is preferred that the compositions hereof not contain borate or material which can form borate in situ (i.e. borate-forming material) under detergent storage or wash conditions. Thus it is preferred under these conditions that a non-borate, non-borate-forming bleaching agent is used. Preferably, detergents to be used at these temperatures are substantially free of borate and borate-forming material. As used herein, "substantially free of borate and borate-forming material" shall mean that the composition contains not more than about 2% by weight of borate-containing and borate-forming material of any type, preferably, no more than 1%, more preferably 0%. One category of bleaching agent that can be used encompasses percarboxylic acid bleaching agents and salts thereof. Suitable examples of this class of agents include magnesium monoperoxyphthal- ate hexahydrate, the magnesium salt of eta-chloro 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, all of which are incorporated by reference herein. Highly preferred bleach¬ ing 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., incorporated herein by reference. Another category of bleaching agents that can be used encom- passes the halogen bleaching agents. Examples of hypohalite bleach¬ ing agents, for example, include trichloro isocyanuric acid and the sodium and potassium diehloroisocyanurates and N-chloro and N-bromo alkane sulphonamides. Such materials are normally added at 0.5-10% by weight of the finished product, preferably 1-5% by weight. Peroxygen bleaching agents can also be used. Suitable peroxy- gen bleaching compounds include sodium carbonate peroxyhydrate, sodium pyrophosphate peroxyhydrate, urea peroxyhydrate, and sodium peroxide. Peroxygen bleaching agents 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. Preferred bleach activators incorporated into compositions of the present invention have the general formula: 0 v R - C - L wherein R is an alkyl group containing from about 1 to about 18 carbon atoms wherein the longest linear alkyl chain extending from and including the carbonyl carbon contains from about 6 to about 10 carbon atoms and L is a leaving group, the conjugate acid of which has a pK a in the range of from about 4 to about 13. These bleach activators are described in U.S. Patent 4,915,854, issued April 10, 1990 to Mao, et al . , incorporated herein by reference, and U.S. Patent 4,412,934, which was previously incorporated herein by reference. 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 aluminum phthalocyanines. These materials can be deposited upon the substrate during the washing process. Upon irradiation with light, in the presence of oxygen, such as by hanging clothes out to dry in the daylight, the sulfonated zinc phthalocyanine is activated and, consequently, the substrate is bleached. Preferred zinc phthalocya¬ nine and a photoactivated bleaching process are described in U.S. Patent 4,033,718, issued July 5, 1977 to Holco be et al., incorpor- ated herein by reference. Typically, detergent compositions will contain about 0.025% to about 1.25%, by weight, of sulfonated zinc phthalocyanine. Polymeric Soil Release Agent Any polymeric soil release agents known to those skilled in the art can be employed in the practice 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. Whereas it can be beneficial to utilize polymeric soil release agents in any of the detergent compositions hereof, especially those compositions utilized for laundry or other applications wherein removal of grease and oil from hydrophobic surfaces is needed, the presence of polyhydroxy fatty acid amide in detergent compositions also containing anionic surfactants can enhance performance of many of the more commonly utilized types of polymeric soil release agents. Anionic surfactants interfere with the ability of certain soil release agents to deposit upon and adhere to hydrophobic surfaces. These polymeric soil release agents have nonionic hydrophile segments or hydrophobe segments which are anionic surfactant-interactive. The compositions hereof for which improved polymeric soil release agent performance can be obtained through the use of polyhydroxy fatty acid amide are those which contain an anionic surfactant system, an anionic surfactant-interactive soil release agent and a soil release agent-enhancing amount of the polyhydroxy fatty acid amide (PFA), wherein: (I) anionic surfactant- interaction between the soil release agent and the anionic surfactant system of the detergent composition can be shown by a comparison of the level of soil release agent (SRA) deposition on hydrophobic fibers (e.g., polyester) in aqueous solution between (A) a "Control" run wherein deposition of the SRA of the detergent composition in aqueous solution, in the absence of the other detergent ingredients, is measured, and (B) an "SRA/Anionic surfactant" test run wherein the same type and amount of the anionic surfactant system utilized in detergent composition is combined in aqueous solution with the SRA, at the same weight ratio of SRA to the anionic surfactant system of the detergent composition, whereby reduced deposition in (B) relative to (A) indicates anionic-surfactant interaction; and (II) whether the detergent composition contains a soil release agent-enhancing amount of polyhydroxy fatty acid amide can be determined by a comparison of the SRA deposition of the SRA/Anionic surfactant test run of (B) with soil release agent deposition in (C) an "SRA/Anionic surf ctant/PFA test run" wherein the same type and level of polyhydroxy fatty acid amide of the detergent composition is combined with the soil release agent and anionic surfactant system corresponding to said SRA/Anionic surfactant test run, whereby improved deposition of the soil release agent in test run (C) relative to test run (B) indicates that a soil release agent- enhancing amount of polyhydroxy fatty acid amide is present. For purposes hereof, the tests hereof should be conducted at anionic surfactant concentrations in the aqueous solution that are above the critical micelle concentration (CMC) of the anionic surfactant and preferably above about 100 ppm. The polymeric soil release agent concentration should be at least 15 ppm. A swatch of polyester fabric should be used for the hydrophobic fiber source. Identical swatches are immersed and agitated in 35°C aqueous solutions for the respective test runs for a period of 12 minutes, then removed, and analyzed. Polymeric soil release agent deposition level can be determined by radiotagging the soil release agent prior to treatment and subsequently conducting radiochemical analysis, according to techniques known in the art. As an alternative to the radiochemical analytical methodology discussed above, soil release agent deposition can alternately be determined in the above test runs (i.e., test runs A, B, and C) by determination of ultraviolet light (UV) absorbance of the test solutions, according to techniques well known in the art. Decreased UV absorbance in the test solution after removal of the hydrophobic fiber material corresponds to increased SRA deposition. As will be understood by those skilled in the art, UV analysis should not be utilized for test solutions containing types and levels of materials which cause excessive UV absorbance interference, such as high levels of surfactants with aromatic groups (e.g., alkyl benzene sulfonates, etc.). Thus by "soil release agent-enhancing amount" of polyhydroxy fatty acid amide is meant an amount of such surfactant that will enhance deposition of the soil release agent upon hydrophobic fibers, as described above, or an amount for which enhanced grease/oil cleaning performance can be obtained for fabrics washed in the detergent composition hereof in the next subsequent cleaning operation. The amount of polyhydroxy fatty acid amide needed to enhance deposition will vary with the anionic surfactant selected, the amount of anionic surfactant, the particular soil release agent chosen, as well as the particular polyhydroxy fatty acid amide chosen. Generally, compositions will comprise from about 0.01% to about 10%, by weight, of the polymeric soil release agent, typically from about 0.1% to about 5%, and from about 4% to about 50%, more typically from about 5% to about 30% of anionic surfactant. Such compositions should generally contain at least about 1%, preferably at least about 3%, by weight, of the polyhydroxy fatty acid amide, though it is not intended to necessarily be limited thereto. The polymeric soil release agents for which performance is enhanced by polyhydroxy fatty acid amide in the presence of anionic surfactant 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 saiα 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 thereof, (iii) poly (vinyl ester) segments, preferably poly(vinyl acetate), having a degree of polymerization of at least 2, or (iv) C1-C4 alkyl ether or C4 hydroxyalkyl ether substituents, or mixtures thereof, wherein said substituents are present in the form of C1-C4 alkyl ether or C4 hydroxyalkyl ether cellulose derivatives, or mixtures thereof, and such cellulose derivatives are amphiphilic, whereby they have a sufficient level of C1-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 2 to about 200, although higher levels can be used, preferably from 3 to about 150, more preferably from 6 to about 100. Suitable oxy C4-C6 alkylene hydrophobe segments include, but are not limited to, end-caps of polymeric soil release agents such as Mθ3S(CH2)nOCH2CH2θ-, where M is sodium and n is an integer from 4-6, as disclosed in U.S. Patent 4,721,580, issued January 26, 1988 to Gosselink, incorporated herein by reference.

Cellulosic soil release agents for use herein also include those selected from the group consisting of C1-C4 alkyl and C4 hydroxyalkyl cellulose such as methylcellulose, ethylcellulose, hydroxypropyl methylcellulose, and hydroxybutyl methylcellulose. A variety of cellulose derivatives useful as soil release polymers are disclosed in U.S. Patent 4,000,093, issued December 28, 1976 to Nicol, et al., incorporated herein by reference. Soil release agents characterized by poly(vinyl ester) hydrophobe segments include graft copolymers of poly(vinyl ester), e.g., Ci-Cβ vinyl esters, preferably poly(vinyl acetate) grafted onto polyalkylene oxide backbones, such as polyethylene oxide backbones. Such materials are known in the art and are described in European Patent Application 0 219 048, published April 22, 1987 by Kud, et al . Suitable commercially available soil release agents of this kind include the SokalanTM type of material, e.g., SokalanTM HP-22, available from BASF (West Germany). One type of preferred soil release agent is a copolymer having random blocks of ethylene terephthalate and polyethylene oxide (PEO) terephthalate. More specifically, these polymers are comprised of repeating units of ethylene terephthalate and PEO terephthalate in a mole ratio of ethylene terephthalate units to PEO terephthalate units of from about 25:75 to about 35:65, said PEO terephthalate units containing polyethylene oxide having molecular weights of from about 300 to about 2000. The molecular weight of this polymeric soil release agent is in the range of from about 25,000 to about 55,000. See U.S. Patent 3,959,230 to Hays, issued May 25, 1976, which is incorporated by reference. See also U.S. Patent 3,893,929 to Basadur issued July 8, 1975 (incorporated by reference) which discloses similar copolymers. Another preferred polymeric soil release agent is a polyester with repeat units of ethylene terephthalate units containing 10-15% by weight of ethylene terephthalate units together with 90-80% by weight of polyoxyethylene terephthalate units, derived from a polyoxyethylene glycol of average molecular weight 300-5,000, and the mole ratio of ethylene terephthalate units to polyoxyethylene terephthalate units in the polymeric compound is between 2:1 and. 6:1. Examples of this polymer include the commercially available material Zelcon R 5126 (from Dupont) and Milease R T (from ICI). These polymers and methods of their preparation are more fully described in U.S. Patent 4,702,857, issued October 27, 1987 to Gosselink, which is incorporated herein by reference. Another preferred polymeric soil release agent is a sulfonated product of a substantially linear ester oligomer comprised of an oligomeric ester backbone of terephthaloyl and oxyalkyleneoxy repeat units and terminal moieties covalently attached to the backbone, said soil release agent being derived from allyl alcohol ethoxylate, dimethyl terephthalate, and 1,2 propylene diol, wherein after sulfonation, the terminal moieties of each oligomer have, on average, a total of from about 1 to about 4 sulfonate groups. These soil release agents are described fully in U.S. Patent 4,968,451, issued November 6, 1990 to J. J. Scheibel and E. P. Gosselink, U.S. Serial No. 07/474,709, filed January 29, 1990, incorporated herein by reference. Other suitable polymeric soil release agents include the ethyl- or methyl-capped 1,2-propylene terephthalate-polyoxyethylene terephthalate polyesters of U.S. Patent 4,711,730, issued December 8, 1987 to Gosselink et al., the anionic end-capped oligomeric esters of U.S. Patent 4,721,580, issued January 26; 1988 to Gosselink, wherein the anionic end-caps comprise sulfo-polyethoxy groups derived from polyethylene glycol (PEG), the block polyester oligomeric compounds of U.S. Patent 4,702,857, issued October 27, 1987 to Gosselink, having polyethoxy end-caps of the formula X-(0CH2CH2)n- wherein n is from 12 to about 43 and X is a C1-C4 alkyl, or preferably methyl, all of these patents being incorporated herein by reference. Additional polymeric soil release agents include the soil release agents of U.S. Patent 4,877,896, issued October 31, 1989 to Maldonado et al . , which discloses anionic, especially sulfoaroyl, end-capped terephthalate esters, said patent being incorporated herein by reference. The terephthalate esters contain unsym etrically substituted oxy-l,2-alkyleneoxy units. Included among the soil release polymers of U.S. Patent 4,877,896 are materials with polyoxyethylene hydrophile components or C3 oxyalkylene terephthalate (propylene terephthalate) repeat units within the scope of the hydrophobe components of (b)(i) above. It is the polymeric soil release agents characterized by either, or both, of these criteria that particularly benefit from the inclusion of the polyhydroxy fatty acid amides hereof, in the presence of anionic surfactants. If utilized, soil release agents will generally comprise from about 0.01% to about 10.0%, by weight, of the detergent compositions herein, typically from about 0.1% to about 5%, preferably from about 0.2% to about 3.0%. Chelating Agents The detergent compositions herein may also optionally contain one or more iron and manganese chelating agents as a builder adjunct material. Such chelating agents can be selected from the group consisting of amino carboxylates, amino phosphonates, polyfunctionally -substituted aromatic chelating agents and mixtures thereof, all as hereinafter defined. 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 in compositions of the invention can have one or more, preferably at least two, units of the substructure CH2 m N - (CH2)χ - COOM, wherein M is hydrogen, alkali metal, ammonium or substituted ammonium (e.g. ethanolamine) and x is from 1 to about 3, preferably 1.

Preferred compounds of this type in acid form are dihydroxydisulfobenzenes, such as 1,2-dihydroxy -3,5-disulfobenzene. Alkaline detergent compositions can contain these materials in the form of alkali metal, ammonium or substituted ammonium (e.g. mono-or triethanol-amine) salts. If utilized, these chelating agents will generally comprise from about 0.1% to about 10% by weight of the detergent compositions herein. More preferably chelating agents will comprise from about 0.1% to about 3.0% by weight of such compositions.

Other clay soil removal and/or anti redeposition agents known in the art can also be utilized in the compositions hereof. Another type of preferred anti-redeposition agent includes the carboxy methyl cellulose (CMC) materials. These materials are well known in the art. Polymeric Dispersing Agents Polymeric dispersing agents can advantageously be utilized in the compositions hereof. These materials can aid in calcium and magnesium hardness control. Suitable polymeric dispersing agents include polymeric polycarboxylates and polyethylene glycol, although others known in the art can also be used. It is believed, though it is not intended to be limited by theory, that polymeric dispersing agents enhance overall detergent builder performance, when used in combination with other builders (including lower molecular weight polycarboxylates) by crystal growth inhibition, particulate soil peptization, and anti-redeposition. Polymeric dispersing agents are generally used at levels of about 0.5% to about 5%, by weight, of the detergent composition, more generally from about 1.0% to about 2.0%. The polycarboxylate materials which can be employed as polymeric dispersing agent herein are these polymers or copolymers which contain at least about 60% by weight of segments with the general formula X Z C - C C00M wherein X, Y, and Z are each selected from the group consisting of hydrogen, methyl, carboxy, carboxy ethyl, hydroxy and hydroxy ethyl ; a salt-forming cation and n is from about 30 to about 400. Prefer¬ ably, X is hydrogen or hydroxy, Y is hydrogen or carboxy, Z is hydrogen and M is hydrogen, alkali metal, ammonia or substituted ammonium. Polymeric polycarboxylate materials of this type can be prepared by polymerizing or copolymerizing suitable unsaturated monomers, preferably in their acid form. Unsaturated monomeric acids that can be polymerized to form suitable polymeric polycarboxylates include acrylic acid, maleic acid (or maleic anhydride), fumaric acid, itaconic acid, aconitic acid, mesaconic acid, citraconic acid and methylenemalonic acid. The presence in the polymeric polycarboxylates herein of monomeric segments, containing no carboxylate radicals such as vinylmethyl ether, styrene, ethylene, etc. is suitable provided that such segments do not constitute more than about 40% by weight. Particularly suitable polymeric polycarboxylates can be derived from acrylic acid. Such acrylic acid-based polymers which are useful herein are the water-soluble salts of polymerized acrylic acid. The average molecular weight of such polymers in the acid form preferably ranges from about 2,000 to 10,000, more preferably from about 4,000 to 7,000 and most prefereably from about 4,000 to 5,000. Water-soluble salts of such acrylic acid polymers can include, for example, the alkali metal, ammonium and substituted ammonium salts. Soluble polymers of this type are known materials." Use of polyacrylates of this type in detergent compositions has been disclosed, for example, in Diehl, U.S. Patent No. 3,308,067, issued March 7; 1967. This patent is incorporated herein by reference. Acrylic/maleic-based copolymers may also be used as a preferred component of the dispersing/anti-redeposition agent. Such materials include the water-soluble salts of copolymers of acrylic acid and maleic acid. The average molecular weight of such copolymers in the acid form preferably ranges from about 2,000 to 100,000, more preferably from about 5,000 to 75,000, most preferably from about 7,000 to 65,000. The ratio of acrylate to maleate segments in such copolymers will generally range from about 30:1 to about 1:1, more preferably from about 10:1 to 2:1. Water-soluble salts of such acrylic acid/maleic acid copolymers can include, for example, the alkali metal, ammonium and substituted ammonium salts. Soluble acrylate/maleate copolymers of this type are known materials which are described in European Patent Application No. 66915, published December 15, 1982, which publication is incorporated herein by reference. 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/anti-redeposition agent. Typical molecular weight ranges for these purposes range from about 500 to about 100,000, preferably from about 1,000 to about 50,000, more preferably from about 1,500 to about 10,000. Brightener Any optical brighteners or other brightening or whitening agents known in the art can be . incorporated into the detergent compositions hereof. The choice of brightener for use in detergent compositions will depend upon a number of factors, such as the type of detergent, the nature of other components present in the detergent composition, the temperatures of wash water, the degree of agitation, and the ratio of the material washed to tub size. The brightener selection is also dependent upon the type of material to be cleaned, e.g., cottons, synthetics, etc. Since most laundry detergent products are used to clean a variety of fabrics, the detergent compositions should contain a mixture of brighteners which will be effective for a variety of fabrics. It is of course necessary that the individual components of such a brightener mixture be compatible. 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.

Suds Suppressors Compounds known, or which become known, for reducing or suppressing the formation of suds can be incorporated into the compositions of the present invention. The incorporation of such materials, hereinafter "suds suppressors," can be desirable because the polyhydroxy fatty acid amide surfactants hereof can increase suds stability of the detergent compositions. Suds suppression can be of particular importance when the detergent compositions include a relatively high sudsing surfactant in combination with the polyhydroxy fatty acid amide surfactant. Suds suppression is particularly desirable for compositions intended for use in front loading automatic washing machines. These machines are typically characterized by having drums, for containing the laundry and wash water, which have a horizontal axis and rotary action about the axis. This type of agitation can result in high suds formation and, consequently, in reduced cleaning performance. The use of suds suppressors can also be of particular importance under hot water washing conditions and under high surfactant concentration conditions. A wide variety of materials may be used as suds suppressors in the compositions hereof. Suds suppressors are well known to those skilled in the art. They are generally described, for example, in 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 acids and soluble salts thereof. These materials are discussed in U.S. Patent 2,954,347, issued September 27, 1960 to Wayne St. John, said patent being incorporated herein by reference. The monocarboxylic fatty acids, and salts thereof, for use 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. These materials are a preferred category of suds suppressor for detergent compositions. The detergent compositions may also contain non-surfactant suds suppressors. These include, for example, list: 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-alkyl elamines 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., Na, K, 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 5"C, and a minimum boiling point not less than about 110 β C (atmospheric pressure). It is also known to utilize waxy hydrocarbons, preferrably having a melting point below about lOO'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 . , incorporated herein by reference. 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 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 polyorgano¬ siloxane is chemisorbed of fused onto the silica. Silicone suds suppressors are well known in the art and are, for example, dis- closed 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., both incorporated herein by reference. 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 1500 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)3 SiOχ/2 units of Siθ2 units in a ratio of from (CH3)3 SiOχ/2 units and to Siθ2 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 ; 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 amount of suds control will vary with the detergent surfactants selected. For example, with high sudsing surfactants, relatively more of the suds controlling agent is used to achieve the desired suds control than with lesser foaming surfactants. In general, a sufficient amount of suds suppressor should be incorporated in low sudsing • detergent compositions so that the suds that form during the wash cycle of the automatic washing machine (i.e., upon agitation of the detergent in aqueous solution under the intended wash temperature and concentration conditions) do not exceed about 75% of the void volume of washing machine's containment drum, preferably the suds do not exceed about 50% of said void volume, wherein the void volume is determined as the difference between total volume of the containment drum and the volume of the water plus the laundry. The compositions hereof will generally comprise from 0% to about 5% of suds suppressor. When utilized as suds suppressors, monocarboxylic fatty acids, and salts thereof, 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 primarly to concern with keeping costs minimized and effectiveness of lower amounts for effectively controlling sudsing. Preferably from about .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 phosphates 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 .01% to about 5.0%, although higher levels can be used. Other Ingredients A wide variety of other ingredients useful in detergent compositions can be included in the compositions hereof, including other active ingredients, carriers, hydrotropes, processing aids, dyes or pigments, solvents for liquid formulations, etc. Liquid detergent compositions can contain water and other solvents as carriers. Low molecular weight primary or secondary alcohols exemplified by methanol , ethanol, propanol, and isopropanol are suitable. Monohydric alcohols are preferred for solubilizing surfactant, but polyols such as those containing from 2 to about 6 carbon atoms and from 2 to about 6 hydroxy groups (e.g., propylene glycol, ethylene glycol, glycerine, and 1,2-propanediol) can also be used. The detergent compositions hereof 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 11, preferably, between about 7.5 and about 10.5. Liquid product formulations preferably have a pH between about 7.5 and about 9.5, more preferably between about 7.5 and about 9.0. Techniques for controlling pH are known in the art and include the use of buffers, acids, alkalis, etc. This invention further provides a method for improving the performance of detergents containing anionic, nonionic, and/or cationic surfactants and alkyl ester sulfonate surfactants by incorporating into such composition the polyhydroxy fatty acid amide surfactant described above, such that the weight ratio of alkyl ester sulfonate surfactant to the amide surfactant is from about 1:10 to about 10:1, in the presence of water or water-miscible solvent (e.g., primary and secondary alcohols). Agitation is preferably provided to facilitate cleaning. Suitable means for providing agitation include washing by hand, with or without a cleaning device such as (but not limited to) a brush, sponge, cleaning cloth, paper towel, mop, etc., automatic laundry washing machine, automatice dishwashing machine, etc. This invention further provides a method for cleaning substrates, such as fibers, fabrics, hard surfaces, skin, etc., by contacting said substrate with a detergent composition comprising one or more anionic, nonionic, or cationic surfactants, at least about 1% alkyl ester sulfonate surfactant, and at least 1% of the polyhydroxy fatty acid amide, wherein preferably of the weight ratio of alkyl ester sulfonate surfactant:the amide surfactant is from about 1:10 to about 10:1. In the above ' methods, the more preferred alkyl ester sulfonate surfactant:polyhydroxy fatty acid amide weight ratios are from about 1:5 to about 5:1, most preferably from about 1:3 to about 3:1. EXPERIMENTAL This procedure exemplifies a process for making a N-methyl, 1-deoxyglucityl lauramide surfactant for use herein. Although a skilled chemist can vary apparatus configuration, one suitable apparatus for use herein comprises a three-liter four-necked flask fitted with a motor-driven paddle stirrer and a thermometer of length sufficient to contact the reaction medium. The other two necks of the flask are fitted with a nitrogen sweep and a wide-bore side-arm (caution: a wide-bore side-arm is important in case of very rapid methanol evolution) to which is connected an efficient collecting condenser and vacuum outlet. The latter is connected to a nitrogen bleed and vacuum gauge, then to an aspirator and a trap. A 500 watt heating mantle with a variable transformer temperature controller ("Variac") used to heat the reaction is so placed on a lab-jack that it may be readily raised or lowered to further control temperature of the reaction. N-methylglucamine (195 g., 1.0 mole, Aldrich, M4700-0) and methyl laurate (Procter & Gamble CE 1270, 220.9 g., 1.0 mole) are placed in a flask. The solid/liquid mixture is heated with stirring under a nitrogen sweep to form a melt (approximately 25 minutes). When the melt temperature reaches 145 * C, catalyst (anhydrous powdered sodium carbonate, 10.5 g., 0.1 mole, J. T. Baker) is added. The nitrogen sweep is shut off and the aspirator and nitrogen bleed are adjusted to give 5 inches (5/31 atm.) Hg. vacuum. From this point on, the reaction temperature is held at 150" C by adjusting the Variac and/or by raising or lowering the mantle. Within 7 minutes, first methanol bubbles are sighted at the meniscus of the reaction mixture. A vigorous reaction soon follows. Methanol is distilled over until its rate subsides. The vacuum is adjusted to give about 10 inches Hg. (10/31 atm.) vacuum. The vacuum is increased approximately as follows (in inches Hg. at minutes): 10 at 3, 20 at 7, 25 at 10. 11 minutes from the onset of methanol evolution, heating and stirring are discontinued coincident with some foaming. The product is cooled and solidifies. The following examples are meant to exemplify compositions of the present invention, but are not necessarily meant to limit or otherwise define the scope of the invention, said scope being determined according to claims which follow. EXAMPLES 1-9 These examples show granular detergent compositions of the present invention containing alkyl ester sulfonate and polyhydroxy fatty acid amide surfactants. concentration levels of about 1350 ppm, wash water basis, at wash temperatures of less than about 50 C. These compositions can be made by spray drying a slurry of the ingredients of the base granule to a moisture of about 5-8%, admixing the granular enzyme and spraying on the liquid nonionic surfactant and perfume. Optionally, a portion or all of the surfactants in the base granule can be admixed as ground particles in the size range from .1 to 1 mm in diameter.

Remaining dry ingredients are added and mixed in a rotary mix drum, followed by spray on addition of the final liquid ingredients. EXAMPLE 10 An alternate method for preparing the polyhydroxy fatty acid amides used herein is as follows. A reaction mixture consisting of 84.87g. fatty acid methyl ester (source: Procter & Gamble methyl ester CE1270), 75g. N-methyl-D-glucamine (source: Aldrich Chemical Company M4700-0), 1.04g. sodium methoxide (source: Aldrich Chemical Company 16,499-2), and 68.51g. methyl alcohol is used. The reaction vessel comprises a standard reflux set-up fitted with a drying tube, condenser and stir bar. In this procedure, the N-methyl glucamine is combined with methanol with stirring under argon and heating is begun with good mixing (stir bar; reflux). After 15-20 minutes, when the solution has reached the desired temperature, the ester and sodium methoxide catalyst are added. Samples are taken periodically to monitor the course of the reaction, but it is noted that the solution is completely clear by 63.5 minutes. It is judged that the reaction is, in fact, nearly complete at that point. The reaction mixture is maintained at reflux for 4 hours. After removal of the methanol, the recovered crude product weighs 156.16 grams. After vacuum drying and purification, an overall yield of 106.92 grams purified product is recovered. However, percentage yields are not calculated on this basis, inasmuch as regular sampling throughout the course of the reaction makes an overall percentage yield value meaningless. The reaction can be carried out at 80% and 90% reactaat concentrations for periods up to 6 hours to yield products with extremely small by-product formation. The following is not intended to limit the invention herein, but is simply to further illustrate additional aspects of the technology which may be considered by the formulator in the manufacture of a wide variety of detergent compositions using the polyhydroxy fatty acid amides. It will be readily appreciated that the polyhydroxy fatty acid amides are, by virtue of their amide bond, subject to some instability under highly basic or highly acidic conditions. While some decomposition can be tolerated, it is preferred that these materials not be subjected to pH's above about 11, preferably 10, nor below about 3 for unduly extended periods. Final product pH (liquids) is typically 7.0-9.0. During the manufacture of the polyhydroxy fatty acid amides it will typically be necessary to at least partially neutralize the base catalyst used to form the amide bond. While any acid can be used for this purpose, the detergent formulator will recognize that it is a simple and convenient matter to use an acid which provides an anion that is otherwise useful and desirable in the finished detergent composition. For example, citric acid can be used for purposes of neutralization and the resulting citrate ion (ca. 1%) be allowed to remain with a ca . 40% polyhydroxy fatty acid amide slurry and be pumped into the later manufacturing stages of the overall detergent-manufacturing process. The acid forms of materials such as oxydisuccinate, nitrilotriacetate, ethylenediaminetetraacetate, tartrate/succinate, and the like, can be used similarly. The polyhydroxy fatty acid amides derived from coconut alkyl fatty acids (predominantly C 12 -C 14 ) are more soluble than their tallow alkyl (predominantly C 16 -C 18 ) counterparts. Accordingly, the C 12 -C 14 materials are somewhat easier to formulate in liquid compo¬ sitions, and are more soluble in cool-water laundering baths. However, the C 16 -C 18 materials are also quite useful, especially under circumstances where warm-to-hot wash water is used. Indeed, the C 16 -C 18 materials may be better detersive surfactants than their C 12 -C 14 counterparts. Accordingly, the formulator may wish to balance ease-of-manufacture vs. performance when selecting a partic¬ ular polyhydroxy fatty acid amide for use in a given formulation. It will also be appreciated that the solubility of the polyhy- droxy fatty acid amides can be increased by having points of unsat- uration and/or chain branching in the fatty acid moiety. Thus, materials such as the polyhydroxy fatty acid amides derived from oleic acid and iso-stearic acid are more soluble than their n-alkyl counterparts. Likewise, the solubility of polyhydroxy fatty acid amides prepared from disaccharides, trisaccharides, etc., will ordinarily be greater than the solubility of their monosaccharide-derived counterpart materials. This higher solubility can be of particular assistance when formulating liquid compositions. Moreover, the polyhydroxy fatty acid amides wherein the polyhydroxy group is derived from maltose appear to function especially well as detergents when used in combination with conventional alkylbenzene sulfonate ("LAS") surfactants. While not intending to be limited by theory, it appears that the combination of LAS with the polyhydroxy fatty acid amides derived from the higher saccharides such as maltose causes a substantial and unexpected lowering of interfacial tension in aqueous media, thereby enhancing net detergency performance. (The manufacture of a polyhydroxy fatty acid amide derived from maltose is described hereinafter.) The polyhydroxy fatty acid amides can be manufactured not only from the purified sugars, but also from hydrolyzed starches, e.g., corn starch, potato starch, or any other convenient plant-derived starch which contains the mono-, di-, etc. saccharide desired by the formulator. This is of particular importance from the economic standpoint. Thus, "high glucose" corn syrup, "high maltose" corn syrup, etc. can conveniently and economically be used. De-lignified, hydrolyzed cellulose pulp can also provide a raw material source for the polyhydroxy fatty acid amides. As noted above, polyhydroxy fatty acid amides derived from the higher saccharides, such as maltose, lactose, etc., are more soluble than their glucose counterparts. Moreover, it appears that the more soluble polyhydroxy fatty acid amides can help solubilize their less soluble counterparts, to varying degrees. Accordingly, the formulator may elect to use a raw material comprising a high glucose corn syrup, for example, but to select a syrup which contains a modicum of maltose (e.g., 1% or more). The resulting mixture of polyhydroxy fatty acids will, in general, exhibit more preferred solubility properties over a broader range of temperatures and concentrations than would a "pure" glucose-derived polyhydroxy fatty acid amide. Thus, in addition to any economic advantages for using sugar mixtures rather than pure sugar reactants, the polyhydroxy fatty acid amides prepared from mixed sugars can offer very substantial advantages with respect to performance and/or ease-of-formulation. In some instances, however, some loss of grease removal performance (dishwashing) may be noted at fatty acid maltamide levels above about 25% and some loss in sudsing above about 33% (said percentages being the percentage of maltamide- derived polyhydroxy fatty acid amide vs. glucose-derived polyhydroxy fatty acid amide in the mixture). This can vary somewhat, depending on the chain length of the fatty acid moiety. Typically, then, the formulator electing to use such mixtures may find it advantageous to select polyhydroxy fatty acid amide mixtures which contain ratios of monosaccharides (e.g., glucose) to di- and higher saccharides (e.g., maltose) from about 4:1 to about 99:1. The manufacture of preferred, uncyclized polyhydroxy fatty acid amides from fatty esters and N-alkyl polyols can be carried out in alcohol solvents at temperatures from about 30°C-90 β C, preferably about 50"C to 80 β C. It has now been determined that it may be convenient for the formulator of, for example, liquid detergents to conduct such processes in 1,2-propylene glycol solvent, since the glycol solvent need not be completely removed from the reaction product prior to use in the finished detergent formulation. Like¬ wise, the formulator of, for example, solid, typically granular, detergent compositions may find it convenient to run the process at 30 β C-90 β C in solvents which comprise ethoxylated alcohols, such as the ethoxylated (EO 3-8) C 12 -C 14 alcohols, such as those available as NEODOL 23 E06.5 (Shell). When such ethoxylates are used, it is preferred that they not contain substantial amounts of unethoxylated alcohol and, most preferably, not contain substantial amounts of mono-ethoxylated alcohol. ("T" designation.) While methods for making polyhydroxy fatty acid amides per se form no part of the invention herein, the formulator can also note other syntheses of polyhydroxy fatty acid amides as described hereinafter. Typically, the industrial scale reaction sequence for preparing the preferred acyclic polyhydroxy fatty acid amides will comprise: Step 1 - preparing the N-alkyl polyhydroxy amine derivative from the desired sugar or sugar mixture by formation of an adduct of the N-alkyl amine and the sugar, followed by reaction with hydrogen in the presence of a catalyst; followed by Step 2 - reacting the aforesaid polyhydroxy amine with, preferably, a fatty ester to form an amide bond. While a variety of N-alkyl polyhydroxy amines useful in Step 2 of the reaction sequence can be prepared by various art-disclosed processes, the following process is convenient and makes use of economical sugar syrup as the raw material. It is to be understood that, for best results when using such syrup raw materials, the manufacturer should select syrups that are quite light in color or, preferably, nearly colorless ("water-white"). Preparation of N-Alkyl Polyhydroxy Amine From Pl nt-Derived Sugar Syrup I. Adduct Formation - The following is a standard process in which about 420 g of about 55% glucose solution (corn syrup - about 231 g glucose - about 1.28 moles) having a Gardner Color of less than 1 is reacted with about 119 g of about 50% aqueous methylamine (59.5 g of methylamine - 1.92 moles) solution. The methylamine (MMA) solution is purged and shielded with N 2 and cooled to about 10 β C, or less. The corn syrup is purged and shielded with N 2 at a temperature of about 10°-20 β C. The corn syrup is added slowly to the MMA solution at the indicated reaction temperature as shown. The Gardner Color is measured at the indicated approximate times in minutes. TABLE 1 As can be seen from the above data, the Gardner Color for the adduct is much worse as the temperature is raised above about 30 β C and at about 50 β C, the time that the adduct has a Gardner Color below 7 is only about 30 minutes. For longer reaction, and/or holding times, the temperature should be less than about 20"C. The Gardner Color should be less than about 7, and preferably less than about 4 for good color glucamine. When one uses lower temperatures for forming the adduct, the time to reach substantial equilibrium concentration of the adduct is shortened by the use of higher ratios of amine to sugar. With the 1.5:1 mole ratio of amine to sugar noted, equilibrium is reached in about two hours at a reaction temperature of about 30 β C. At a 1.2:1 mole ratio, under the same conditions, the time is at least about three hours. For good color, the combination of amine:sugar ratio; reaction temperature; and reaction time is selected to achieve substantially equilibrium conversion, e.g., more than about 90%, preferably more than about 95%,, even more preferably more than about 99%, based upon the sugar, and a color that is less than about 7, preferably less than about 4, more preferably less than about 1, for the adduct. Using the above process at a reaction temperature of less than about 20 β C and corn syrups with different Gardner Colors as indicated, the MMA adduct color (after substantial equilibrium is reached in at least about two hours) is as indicated. TABLE 2 Gardner Color (Approximate) Corn syrup 1 1 1 1+ 0 0 0+ Adduct 3 4/5 7/8 7/8 1 2 1 As can be seen from the above, the starting sugar material must be very near colorless in order to consistently have adduct that is acceptable. When the sugar has a Gardner Color of about 1, the adduct is sometimes acceptable and sometimes not acceptable. When the Gardner Color is above 1 the resulting adduct is unacceptable. The better the initial color of the sugar, the better is the color of the adduct. II. Hydrogen Reaction - Adduct from the above having a Gardner Color of 1 or less is hydrogenated according to the following procedure. About 539 g of adduct in water and about 23.1 g of United Catalyst G49B Ni catalyst are added to a one liter autoclave and purged two times with 200 psig H 2 at about 20 C C. The H 2 pressure is raised to about 1400 psi and the temperature is raised to about 50 β C. The pressure is then raised to about 1600 psig and the temperature is held at about 50-55 β C for about three hours. The product is about 95% hydrogenated at this point. The temperature is then raised to about 85 β C for about 30 minutes and the reaction mixture is decanted and the catalyst is filtered out. The product, after removal of water and MMA by evaporation, is about 95% N-methyl glucamine, a white powder. The above procedure is repeated with about 23.1 g of Raney Ni catalyst with the following changes. The catalyst is washed three times and the reactor, with the catalyst in the reactor, is purged twice with 200 psig H 2 and the reactor is pressurized with H 2 at 1600 psig for two hours, the pressure is released at one hour and the reactor is repressurized to 1600 psig. The adduct is then pumped into the reactor which is at 200 psig and 20 * C, and the reactor is purged with 200 psig H 2 , etc., as above. The resulting product in each case is greater than about 95% N-methyl glucamine; has less than about 10 ppm Ni based upon the glucamine; and has a solution color of less than about Gardner 2. The crude N-methyl glucamine is color stable to about 140 β C for a short exposure time. It is important to have good adduct that has low sugar content (less than about 5%, preferably less than about 1%) and a good color (less than about 7, preferably less than about 4 Gardner, more preferably less than about 1). In another reaction, adduct is prepared starting with about 159 g of about 50% methylamine in water, which is purged and shielded with N 2 at about 10-20 * C. About 330 g of about 70% corn syrup (near water-white) is degassed with N 2 at about 50 β C and is added slowly to the methylamine solution at a temperature of less than about 20'C. The solution is mixed for about 30 minutes to give about 95% adduct that is a very light yellow solution. About 190 g of adduct in water and about 9 g of United Catalyst G49B Ni catalyst are added to a 200 ml autoclave and purged three ■ times with H 2 at about 20 e C. The H 2 pressure is raised to about 200 psi and the temperature is raised to about 50 β C. The pressure is raised to 250 psi and the temperature is held at about 50-55 β C for about three hours. The product, which is about 95% hydrogenated at " this point, is then raised to a temperature of about 85"C for about 30 minutes and the product, after removal of water and evaporation, is about 95% N-methyl glucamine, a white powder. It is also important to minimize contact between adduct and catalyst when the H 2 pressure is less than about 1000 psig to minimize Ni content in the glucamine. The nickel content in the N-methyl glucamine in this reaction is about 100 ppm as compared to the less than 10 ppm in the previous reaction. The following reactions with H 2 are run for direct comparison of reaction temperature effects. A 200 ml autoclave reactor is used following typical procedures similar to those set forth above to make adduct and to run the hydrogen reaction at various temperatures. Adduct for use in making glucamine is prepared by combining about 420 g of about 55% glucose (corn syrup) solution (231 g glucose; 1.28 moles) (the solution is made using 99DE corn syrup from CarGill, the solution having a color less than Gardner 1) and about 119 g of 50% methylamine (59.5 g MMA; 1.92 moles) (from Air Products) . The reaction procedure is as follows: 1. Add about 119 g of the 50% methylamine solution to a N 2 purged reactor, shield with N 2 and cool down to less than about 10"C. 2. Degas and/or purge the 55% corn syrup solution at 10-20 β C with N 2 to remove oxygen in the solution. 3. Slowly add the corn syrup solution to the methylamine solution and keep the temperature less than about 20 β C. 4. Once all corn syrup solution is added in, agitate for about 1-2 hours. The adduct is used for the hydrogen reaction right after making, or is stored at low temperature to prevent further degradation. The glucamine adduct hydrogen reactions are as follows: 1. Add about 134 g adduct (color less than about Gardner 1) and about 5.8 g G49B Ni to a 200 ml autoclave. 2. Purge the reaction mix with about 200 psi H 2 twice at about 20-30°C. 3. Pressure with H 2 to about 400 psi and raise the temperature to about 50 β C. 4. Raise pressure to about 500 psi, react for about 3 hours. Keep temperature at about 50-55°C. Take Sample 1. 5. Raise temperature to about 85°C for about 30 minutes. 6. Decant and filter out the Ni catalyst. Take Sample 2. Conditions for constant temperature reactions: 1. Add about 134 g adduct and about 5.8 g G49B Ni to a 200 ml autoclave. 2. Purge with about 200 psi H 2 twice at low temperature. 3. Pressure with H 2 to about 400 psi and raise temperature to about 50°C. 4. Raise pressure to about 500 psi, react for about 3.5 hours. Keep temperature at indicated temperature. 5. Decant and filter out the Ni catalyst. Sample 3 is for about 50-55'C; Sample 4 is for about 75 β C; and Sample 5 is for about 85 * C. (The reaction time for about 85 β C is about 45 minutes.) All runs give similar purity of N-methyl glucamine (about 94%); the Gardner Colors of the runs are similar right after reaction, but only the two-stage heat treatment gives good color stability; and the 85 β C run gives marginal color immediately after reaction. EXAMPLE 11 The preparation of the substantially acyclic tallow (hardened) fatty acid amide of N-methyl maltamine for use in detergent compositions according to this invention is as follows. Step 1 - Reactants: Maltose onohydrate (Aldrich, lot 01318KW); methylamine (40 wt% in water) (Aldrich, lot 03325TM) ; Raney nickel, 50% slurry (UAD 52-73D, Aldrich, lot 12921LW). The reactants are added to glass liner (250 g maltose, 428 g methylamine solution, 100 g catalyst slurry - 50 g Raney Ni) and placed in 3 L rocking autoclave, which is purged with nitrogen (3X500 psig) and hydrogen (2X500 psig) and rocked under H 2 at room temperature over a weekend at temperatures ranging from 28 β C to 50'C. The crude reaction mixture is vacuum filtered 2X through a glass microfiber filter with a silica gel plug. The filtrate is concentrated to a viscous material. The final traces of water are azetroped off by dissolving the material in methanol and then removing the methanol/water on a rotary evaporator. Final drying is done under high vacuum. The crude product is dissolved in refluxing methanol, filtered, cooled to recrystallize, filtered and the filter cake is dried under vacuum at 35"C. This is cut #1. The filtrate is concentrated until a precipitate begins to form and is stored in a refrigerator overnight. The solid is filtered and dried under vacuum. This is cut #2. The filtrate is again concentrated to half its volume and a recrystallization is performed. V ry little precipitate forms. A small quantity of ethanol is added and the solution is left in the freezer over a weekend. The solid material is filtered and dried under vacuum. The combined solids comprise N-methyl maltamine which is used in Step 2 of the overall synthesis. Step 2 - Reactants: N-methyl maltamine (from Step 1); hardened tallow methyl esters; sodium methoxide (25% in methanol); absolute methanol (solvent); mole ratio 1:1 amine:ester; initial catalyst level 10 mole % (w/r maltamine), raised to 20 mole %; solvent level 50% (wt.). In a sealed bottle, 20.36 g of the tallow methyl ester is heated to its melting point (water bath) and loaded into a 250 ml 3-neck round-bottom flask with mechanical stirring. The flask is heated to ca . 70°C to prevent the ester from solidifying. Separately, 25.0 g of N-methyl maltamine is combined with 45.36 g of methanol, and the resulting slurry is added to the tallow ester with good mixing. 1.51 g of 25% sodium methoxide in methanol is added. After four hours the reaction mixture has not clarified, so an additional 10 mole % of catalyst (to a total of 20 mole %) is added and the reaction is allowed to continue overnight (ca . 68 β C) after which time the mixture is clear. The reaction flask is then modified for distillation. The temperature is increased to llO'C. Distillation at atmospheric pressure is continued for 60 minutes. High vacuum distillation is then begun and continued for 14 minutes, at which time the product is very thick. The product is allowed to remain in the reaction flask at 110 β C (external temperature) for 60 minutes. The product is scraped from the flask and triturated in ethyl ether over a weekend. Ether is removed on a rotary evaporator and the product is stored in an oven overnight, and ground to a powder. Any remaining N-methyl maltamine is removed from the product using silica gel. A silica gel slurry in 100% methanol is loaded into a funnel and washed several times with 100% methanol. A concentrated sample of the product (20 g in 100 ml of 100% methanol) is loaded onto the silica gel and eluted several times using vacuum and several methanol washes. The collected eluant is evaporated to dryness (rotary evaporator). Any remaining tallow ester is removed by trituration in ethyl acetate overnight, followed by filtration. The filter cake is then vacuum dried overnight. The product is the tallowalkyl N-methyl maltamide. In an alternate mode, Step 1 of the foregoing reaction sequence can be conducted using commercial corn syrup comprising glucose or mixtures of glucose and, typically, 5%, or higher, maltose. The resulting polyhydroxy fatty acid amides and mixtures can be used in any of the detergent compositions herein. In still another mode, Step 2 of the foregoing reaction sequence can be carried out in 1,2-propylene glycol or NEODOL. At the discretion of the formulator, the propylene glycol or NEODOL need not be removed from the reaction product prior to its use to formulate detergent compositions. Again, according to the desires of the formulator, the methoxide catalyst can be neutralized by citric acid to provide sodium citrate, which can remain in the polyhydroxy fatty acid amide. Depending on the desires of the formulator, the compositions herein can contain more or less of various suds control agents. Typically, for dishwashing high sudsing is desirable so no suds control agent will be used. For fabric laundering in top-loading washing machines some control of suds may be desirable, and for front-loaders some considerable degree of suds control may be preferred. A wide variety of suds control agents are known in the art and can be routinely selected for use herein. Indeed, the selection of suds control agent, or mixtures of suds control agents, for any specific detergent composition will depend not only on the presence and amount of polyhydroxy fatty acid amide used therein, but also on the other surfactants present in the formulation. However, it appears that, for use with polyhydroxy fatty acid amides, silicone-based suds control agents of various types are more efficient (i.e., lower levels can be used) than various other types of suds control agents. The silicone suds control agents available as X2-3419 and Q2-3302 (Dow Corning) are particularly useful. . The formulator of fabric laundering compositions which can advantageously contain soil release agent has a wide variety of known materials to choose from (see, for example, U.S. Patents 3,962,152; 4,116,885; 4,238,531; 4,702,857; 4,721,580 and 4,877,896). Additional soil release materials useful herein include the nonionic oligomeric esterification product of a reaction mixture comprising a source of C x -C 4 alkoxy-terminated polyethoxy units (e.g., CH 3 [0CH 2 CH 2 ] 16 0H), a source of terephthaloyl units (e.g., dimethyl terephthalate); a source of poly(oxyethylene)oxy units (e-g. > polyethylene glycol 1500); a source of oxyiso-propyleneoxy units (e.g., 1,2-propylene glycol); and a source of oxyethyleneoxy units (e.g., ethylene glycol) especially wherein the mole ratio of oxyethyleneoxy units:oxyiso-propyleneoxy units is at least about 0.5:1. Such nonionic soil release agents are of the general formula ) alkyl, especially methyl; x and y are each integers from about 6 to about 100; m is an integer of from about 0.75 to about 30; n is an integer from about 0.25 to about 20; and R 2 is a mixture of both H and CH 3 to provide a mole ratio of oxyethyleneox :oxyisopropyleneoxy of at least about 0.5:1. Another preferred type of soil release agent useful herein is of the general anionic type described in U.S. Patent 4,877,896, but with the condition that such agents be substantially free of monomers of the HOROH type wherein R is propylene or higher alkyl. Thus, the soil release agents of U.S. Patent 4,877,896 can comprise, for example, the reaction product of dimethyl terephthalate, ethylene glycol, 1,2-propylene glycol and 3-sodiosulfobenzoic acid, whereas these additional soil release agents can comprise, for example, the reaction product of dimethyl terephthalate, ethylene glycol, 5-sodiosulfoisophthalate and 3-sodiosulfobenzoic acid. Such agents are preferred for use in granular laundry detergents. The formulator may also determine that it is advantageous to include a non-perborate bleach, especially in heavy-duty granular laundry detergents. A variety of peroxygen bleaches are available, commercially, and can be used herein, but, of these, percarbonate is convenient and economical. Thus, the compositions herein can contain a solid percarbonate bleach, normally in the form of the sodium salt, incorporated at a level of from 3% to 20% by weight, more preferably from 5% to 18% by weight and most preferably from 8% to 15% by weight of the composition. Sodium percarbonate is an addition compound having a formula corresponding to 2Na 2 C0 3 . 3H 2 0 2 , and is available commercially as a crystalline solid. Most commercially available material includes a low level of a heavy metal sequestrant such as EDTA, 1-hydroxy- ethylidene 1,1-diphosphonic acid (HEDP) or an amino-phosphonate, that is incorporated during the manufacturing process. For use herein, the percarbonate can be incorporated into detergent composi- tions without additional protection, but preferred embodiments of the invention utilize a stable form of the material (FMC). Although a variety of coatings can be used, the most economical is sodium silicate of Si0 2 :Na 2 0 ratio from 1.6:1 to 2.8:1, preferably 2.0:1, applied as an aqueous solution and dried to give a level of from 2% to 10% (normally from 3% to 5%), of silicate solids by weight of the percarbonate. Magnesium silicate can also be used and a chelant such as one of those mentioned above can also be included in the coating. The particle size range of the crystalline percarbonate is from 350 micrometers to 450 micrometers with a mean of approximately 400 micrometers. When coated, the crystals have a size in the range from 400 to 600 micrometers. While heavy metals present in the sodium carbonate used to manufacture the percarbonate can be controlled by the inclusion of sequestrants in the reaction mixture, the percarbonate still requires protection from heavy metals present as impurities in other ingredients of the product. It has been found that the total level of iron, copper and manganese ions in the product should not exceed 25 ppm and preferably should be less than 20 ppm in order to avoid an unacceptably adverse effect on percarbonate stability. The following relates to the preparation of a preferred liquid heavy duty laundry detergent according to this invention. It will be appreciated that the stability of enzymes in such compositions is considerably less than in granular detergents. However, by using* typical enzyme stabilizers such as formate and boric acid, lipase and cellulase enzymes can be protected from degradation by protease enzymes. However, lipase stability is still relatively poor in the presence of alkylbenzene sulfonate ("LAS") surfactants. Apparently, LAS partially denatures lipase, and, further, it seems that denatured lipase is more vulnerable to attack by protease. In view of the foregoing considerations, which, as noted, can be particularly troublesome in liquid compositions, it is a challenge to provide liquid detergent compositions containing lipase, protease and cellulase enzymes, together. It is particu¬ larly challenging to provide such tertiary enzyme systems in stable liquid detergents together with an effective blend of detersive surfactants. Additionally, it is difficult to incorporate peroxidase and/or a ylase enzymes stably in such compositions. It has now been determined that various mixtures of Upases, proteases, cellulases, amylases and peroxidases are adequately stable in the presence of certain non-alkylbenzene sulfonate surfactant systems, such that effective, heavy-duty solid and even liquid detergents can be formulated. Indeed, the formulation of stable, liquid, enzyme-containing detergent compositions constitutes a highly advantageous and preferred embodiment afforded by the technology of the present invention. In particular, prior art liquid detergent compositions typically contain LAS or mixtures of LAS with surfactants of the R0(A) m S0 3 M type ("AES") noted hereinabove, i.e., LAS/AES mixtures. By contrast, the liquid detergents herein preferably comprise binary mixtures of the AES and polyhydroxy fatty acid amides of the type disclosed herein. While minimal amounts of LAS can be present, it will be appreciated that the stability of the enzymes will be lessened thereby. Accordingly, it is preferred that the liquid compositions be substantially free (i.e., contain less than about 10%, preferably less than about 5%, more preferably less than about 1%, most preferably 0%) of LAS. The present invention provides a liquid detergent composition comprising the alkyl ester sulfonate surfactant and: (a) from about 1% to about 50%, preferably from about 4% to about 40%, of a second anionic surfactant; (b) from about 0.0001% to about 2% of active detersive enzyme; (c) an enzyme performance-enhancing amount (preferably from about 0.5% to about 12%) of a polyhydroxy fatty acid amide material of the formula 0 R 1 Ii I R 2 - C - N - Z wherein R 1 is H 1} Cj-C 4 hydrocarbyl, 2-hydroxy ethyl, 2-hydroxy propyl, or a mixture thereof, R 2 is C 5 -C 31 hydrocarbyl, and Z is a polyhydroxy!hydrocarbyl having a linear hydrocarbyl chain with at least 3 hydroxyls directly connected to said chain, or an alkoxylated derivative thereof; and wherein the composition is substantially free of alkylbenzene sulfonate. The second water-soluble anionic surfactant (a) herein preferably comprises ("AES"): R0(A) m S0 3 M wherein R is an unsubstituted C 10 -C 24 alkyl or hydroxyalkyl (Cιo-C 24 ) group, A is an ethoxy or propoxy unit, m is an integer greater than 0 and M is hydrogen or a cation. Preferably, R is an unsubstituted C 12 -C 18 alkyl group, A is an ethoxy unit, m is from about 0.5 to about 6, and M is a cation. The cation is preferably a metal cation (e.g., sodium-preferred, potassium, lithium, calcium, magnesium, etc.) or an ammonium or substituted ammonium cation. It is preferred that the ratio of the above surfactant ("AES") to the polyhydroxy fatty acid amide herein be from about 1:2 to about 8:1, preferably about 1:1 to about 5:1, most preferably about 1:1 to about 4:1. The liquid compositions herein may alternatively comprise polyhydroxy fatty acid amide, AES, and from about 0.5% to about 5% of the condensation product of C 8 -C 22 (preferably C 10 -C 20 ) linear alcohol with between about 1 and about 25, preferably between about 2 and about 18, moles of ethylene oxide per mole of alcohol. The liquid compositions herein preferably have a pH in a 10% solution in water at 20 β C of from about 6.5 to about 11.0, prefer¬ ably from about 7.0 to about 8.5. The instant compositions preferably further comprise from about 0.1% to about 50% of detergency builder. These compositions preferably comprise from about 0.1% to about 20% of citric acid, or water-soluble salt thereof; or from about 0.1% to about 20% of a water-soluble succinate tartrate, especially the sodium salt thereof, and mixtures thereof, or from about 0.1% to about 20% by weight of oxydisuccinate or mixtures thereof with the aforesaid builders. 0.1%-50% of alkenyl succinate can also be used. The preferred liquid compositions herein comprise from about 0.0001% to about 2%, preferably about 0.0001% to about 1%, most preferably about 0.001% to about 0.5%, on an active basis, of detersive enzyme. These enzymes are preferably selected from the group consisting of protease (preferred), lipase (preferred), amylase, cellulase, peroxidase, and mixtures thereof. Preferred are compositions with two or more classes of enzymes, most preferably where one is a protease. While various descriptions of detergent proteases, cellulases, etc., are available in the literature, detergent lipases may be somewhat less familiar. Accordingly, to assist the formulator, lipases of interest include Amano AKG and Bacillis Sp lipase (e.g., Solvay enzymes). Also, see the lipases described in EP A 0399681, published November 28, 1990, EP A 0 218272, published April 15, 1987 and PCT/DK 88/00177, published May 18, 1989, all incorporated herein by reference. Suitable fungal lipases include those producible by Humicola lanuginosa and Thermomyces lanuginosus . Most preferred is the lipase obtained by cloning the gene from Humicola lanuginosa and expressing the gene in Aspergi l lus oryzae, as described in European Patent Application 0258068, incorporated herein by reference, commercially available under the trade name LIPOLASE. From about 2 to about 20,000, preferably about 10 to about 6,000, lipase units of lipase per gram (LU/g) of product can be used in these compositions. A lipase unit is that amount of lipase which produces 1 /xmol of titratable butyric acid per minute in a pH stat, where pH is 7.0, temperature is 30 β C, and substrate is an emulsion tributyrin and gum arabic, in the presence of Ca ++ and NaCl in phosphate buffer. The following Example illustrates a heavy duty liquid detergent composition.

The brightener can be premixed with the monoethanolamine and water (4.5% brightener, 60% MEA, 35.5% H 2 0) and added to the composition. EXAMPLE 13 In any of the foregoing examples, the fatty acid glucamide surfactant can be replaced by an equivalent amount of the malta ide surfactant, or mixtures of glucamide/maltamide surfactants derived from plant sugar sources. In the compositions the use of ethanol- amides appears to help cold temperature stability of the finished formulations. Moreover, the use of sulfobetaine (aka "sultaine") and/or amine oxide surfactants provides superior sudsing. For compositions where especially high sudsing is desired (e.g., dishwashing), it is preferred that less than 5%, preferably less than 2%, most preferably, substantially no C 14 or higher fatty acids be present, since these can suppress sudsing. Accordingly, the formulator of high sudsing compositions will desirably avoid the introduction of suds-suppressing amounts of such fatty acids into high sudsing compositions with the polyhydroxy fatty acid amide, and/or avoid the formation of C 14 and higher fatty acids on storage of the finished compositions. One simple means is to use C 12 ester reactants to prepare the polyhydroxy fatty acid amides. Fortun¬ ately, the use of amine oxide or sulfobetaine surfactants can overcome some of the negative sudsing effects caused by the fatty acids. The formulator wishing to add anionic optical brighteners to liquid detergents containing relatively high concentrations (e.g., 10% and greater) of anionic or polyanionic substituents such as the polycarboxylate builders may find it useful to pre- ix the bright¬ ener with water and the polyhydroxy fatty acid amide, and then to add the pre-mix to the final composition. Polygluta ic acid or polyaspartic acid dispersants can be usefully employed with zeolite-built detergents. AE fluid or flake and DC-544 (Dow Corning) are other examples of useful suds control agents herein. It will be appreciated by those skilled in the chemical arts that the preparation of the polyhydroxy fatty acid amides herein using the di- and higher saccharides such as maltose will result in the formation of polyhydroxy fatty acid amides wherein linear substituent Z is "capped" by a polyhydroxy ring structure. Such materials are fully contemplated for use herein and do not depart from the spirit and scope of the invention as disclosed and claimed.
