  • the amount of N-higher acyl amino acid which stabilizes the enzyme in a detergent composition may be 0.1 to 20% based on the weight of the detergent base or 20% to 1000% based on the enzyme.
  • Detergent compositions of the invention may be powders, granules, pastes, or liquids.
  • the stabilizers of the invention may be used to advantage in heavy-duty synthetic detergent compositions containing alkaline builder or in light-duty synthetic detergent compositions without alkaline builder whose predominant detergent agent is an anionic, cationic, or nonionic surfactant.
  • N-higher acyl amino acids themselves have excellent surface activity and are stable in hard water. They may be used, therefore, as predominant active ingredients in detergent compositions which may further contain enzymes with or without builders. In such compositions, the enzymes are very stable.
  • N-higher acyl amino acids constitute the primary surfactant in enzyme bearing compositions
  • other synthetic surfactants and builders may also be present. Good detergency and foaming ability are achieved even in hard water without the use of alkaline builders, such as sodium tripolyphosphate and sodium silicate, and the solutions prepared from such compositions may be neutral or only slightly alkaline so as to further enhance the stability of the enzyme.
  • Amylase activity was determined by the modified Wohlgemuth method in which 1 amylase unit is the amount of enzyme which reduces the iodine color of 1 ml. of 0.65% soluble starch solution to an absorbance of 0.300 at 660 mp. in 10 minutes at 40 C.
  • Lipase activity was determined by the method of Yamada et al. [J. Agric. Chem. Soc. Japan 36 (1962) 860], one unit being the amount of enzyme liberating 1p. equivalent of acid per nunute.
  • the acyl groups of the N-higher acyl amino acids in the detergent compositions of the invention are those of saturated or unsaturated fatty acids having 6 to 20 carbon atoms, such as caproic, lauric, tridecanoic, decanoic, myristic, pentadecanoic, palmitic, margaric, stearic, and oleic acid, also of the fatty acid mixtures obtained from fats and oils, such as coconut oil, tallow oil, hydrogenated tallow oil, olive oil, soybean oil, corn oil, and the like.
  • the N-higher acyl amino acids may be used also in the form of their salts with alkali metals (sodium, potassium) or ammonium, with water soluble amines, particularly alkanolamines (mono-, di-, or triethanolamine) and triethylamine, with basic amino acids if the acyl group is attached to an acidic amino acid, or in the form of their acid addition salts with mineral acids (hydrochloric or sulfuric), organic acids (acetic acid, lactic acid, acidic amino acids if the acyl group is attached to a basic amino acid).
  • the amino acid moiety of the N-higher acyl amino acid may be an acidic amino acid (such as glutamic acid, aspartic acid, homocysteic acid, cysteic acid, aminoadipic acid), a basic amino acid (such as lysine, arginine, ornithine, oxylysine, diaminobutyric acid, histidine, isolysine), or a neutral amino acid (such as glycine, alanine, valine, serine, proline, leucine, isoleucine, oxyproline, methionine, phenylalanine, threonine, tryptophane, cystein, cystine, tyrosine, norvaline, norleucine, aminobutyric acid, aminoisobutyric acid, diaminopimelic acid, diaminooxypimelic acid, pantonine, taurine, aminovaleric acid, and aminocaproic acid). It may be optically active or racemic.
  • N-methyl-N-acyl and N-ethyl-N-acyl derivatives of these acids also may be used, such as N-acyl derivatives of N-methylleucine, N-methylglycine, N-methylalanine, dimethyl ornithine, and also N-acyl peptide derivatives.
  • the esters may be the lower alkyl esters (methyl, ethyl, propyl, butyl) or higher alkyl esters (such as octyl, lauryl esters).
  • Alkaline or neutral protease, amylase, and lipase may be used in the detergent compositions of the invention singly or in mixtures of two or more.
  • a synthetic surfactant may be an alkyl benzene sulfonate, the sulfate of a higher alcohol or of an alkyl ethoxy ether, an a-olefin sulfonate, another alkylaryl sulfonate, a polyoxyethylene alkylphenyl ether, and may be mixed with a builder, other auxiliary agents (optical bleach, perfume, dye, CMC to prevent redeposition), the N-higher acyl amino acid, and the enzyme.
  • the N-higher acyl amino acid is the sole or predominant surfactant, it may be combined with a builder, auxiliary agents, and the enzyme.
  • the detergent composition in either case may be in the form of a powder, a shaped solid body, a paste, granules, a cream, an emulsion, or a solution, as may be required.
  • the detergent compositions of the invention have a long shelf life because of the stabilizing efl'ect of the N-higher acyl amino acids on the enzymes, and only little of the enzyme activity is lost during use. Detergency is adequate, because the N-higher acyl amino acids are equal or superior in this respect to conventional detergents with which they are fully compatible.
  • the composition has excellent stability and detergency in hard water without need for alkaline builders which impair enzyme activity.
  • the solutions are neutral or weakly alkaline so that enzymes not suitable for alkaline solutions may be employed singly or in mixtures.
  • the solutions may be employed for degreasing wool, as hair shampoos, and as detergents for kitchen use.
  • the N-higher acyl amino acids tend to protect the skin and rarely cause irritation. They also have antibacterial or bacteriostatic efiects.
  • the detergent compositions of the present invention may therefore be formulated as laundry detergents, for general kitchen use, for use in automatic dish washers, as shampoos, bar soaps, cleaning creams, tooth pastes, and for industrial use.

  • Example 5 50 g. of protease was mixed with a mixture of 3 kg. of sodium N-cocoyl-L-glutamate and 7 kg. of Glaubers salt. The obtained mixture was dissolved in water to make 60 litres and spray-dried to produce neutral laundry detergent for W001 and synthetic fibers.
