Abstract
Abstract The invention concerns an aqueous shampoo comprising an alkyl sulphate or alkyl ether sulphate detergent, a cationic derivative of a polygalactomannan gum as a hair conditioning agent and, for enhancing the deposition of the conditioning agent onto the hair during shampooing, a defined carboxylate, sulphate or phosphate ester anionic additive.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
164 words
An aqueous shampoo consisting essentially of: (A) from 5% to 30% by weight of a detergent selected from alkyl sulphate and alkyl ether sulphate detergents; (B) from 0.05% to 2% by weight of a cationic derivative of a polygalactomannan gum; and (C) from 0.1% to 3% by weight of an anionic additive comprising at least one of (i) a carboxylate of the formula R(OCH.sub.2 CH.sub.2).sub.n COOM (ii) a sulphate of the formula ROSO.sub.3 M (iii) a phosphate ester selected from the group consisting of monoesters of the formula ##STR7## and diesters of the formula ##STR8## and mixtures thereof in which formulae R is a hydrocarbon group having 8 to 22 carbon atoms, n is 0 or an integer of from 1 to 10, and M is selected from the group consisting of hydrogen and alkali metal, ammonium and amine salt forming groups, with the proviso that when the anionic additive component (C) is a sulphate the detergent component (A) is an alkyl ether sulphate.
Claim 2
Dependent Claim
164 words
An aqueous shampoo consisting essentially of: (A) from 5% to 30% by weight of a detergent selected from alkyl sulphate and alkyl ether sulphate detergents; (B) from 0.05% to 2% by weight of a cationic derivative of a polygalactomannan gum; and (C) from 0.1% to 3% by weight of an anionic additive comprising at least one of (i) a carboxylate of the formula R(OCH.sub.2 CH.sub.2).sub.n COOM (ii) a sulphate of the formula ROSO.sub.3 M (iii) a phosphate ester selected from the group consisting of monoesters of the formula ##STR7## and diesters of the formula ##STR8## and mixtures thereof in which formulae R is a hydrocarbon group having 8 to 22 carbon atoms, n is 0 or an integer of from 1 to 10, and M is selected from the group consisting of hydrogen and alkali metal, ammonium and amine salt forming groups, with the proviso that when the anionic additive component (C) is a sulphate the detergent component (A) is an alkyl ether sulphate.
