Liquid detergent composition

Claim 1

A liquid detergent composition which consists essentially of: (A) from 5 to 25 wt. % of an ammonium alkyl sulfate having the formula R.sub.1 OSO.sub.3 NH.sub.4 wherein R 1 is alkyl having from 8 to 18 carbon atoms on the average, (B) from 0.05 to 5 wt. % of one or a mixture of two or more alkylenediaminecarboxylic acid derivatives having the formula ##STR7## wherein R 2 is alkylene having 2 or 3 carbon atoms; A, B, C and D, which are the same or different, each is ##STR8## or hydrogen, in which R 3 is --C n H 2n -- or ##STR9## n is 1 or 2 and Y is hydrogen or a cation, with the proviso that from 0 to 2 of the groups, A, B, C and D are hydrogen and the remainder are ##STR10## (C) from 0.1 to 5 wt. % of one or a mixture of two or more compounds selected from the group consisting of carboxylic acids selected from the group consisting of lower fatty acids having from 1 to 8 carbon atoms, dicarboxylic acids having the formula HOOC--CH 2 -- n COOH wherein n is an integer of from 0 to 5, glycolic acid, lactic acid, hydroacrylic acid, α-hydroxybutyric acid, β-hydroxybutyric acid, glyceric acid, tartronic acid, malic acid, tartaric acid, citric acid, maleic acid, fumaric acid, mesaconic acid and citraconic acid, and amino acids selected from the group consisting of glycine, alanine, valine, leucine, isoleucine, phenylalanine, tryptophane, sarcosine, β-alanine, γ-aminobutyric acid, ε-aminocaproic acid, glutamic acid, aspartic acid, cysteic acid, homocysteic acid, lysine, ornithine, arginine, serine, homoserine, tyrosine, threonine, proline, hydroxyproline, cystine, cysteine and methionine, and salts of said carboxylic acids and said amino acids, and (D) the balance is essentially water.
