Shampoo composition employing anionic phosphoric acid ester surfactant and cationic polymer

Claim 1

A shampoo composition, consisting essentially of (A) from 0.1 to 2.5% by weight of at least one anionic phosphoric acid ester having the formula ##STR11## wherein A is ##STR12## R is alkyl having an average carbon atom number of 8 to 18 or alkenyl having an average carbon atom number of 8 to 18; R 1 is hydrogen or methyl; m is from 0 to 8; n is from 1 to 8; B is --OX 2 or --A; and X 1 and X 2 , which can be the same or different, are hydrogen, alkali metal, alkyl (C 1 -C 3 )-substituted ammonium or hydroxyalkyl (C 1 -C 3 )-substituted ammonium; (B) from 0.05 to 2.5% by weight of at least one cationic polymer effective for conditioning hair selected from the group consisting of (i) copolymers of quaternized vinylpyrrolidone and aminoethyl methacrylate, (ii) copolymers of adipic acid and dimethylaminohydroxypropylene diethylenetriamine, (iii) poly-(N,N-dimethyl-3,5-methylenepiperidinium chloride), (iv) copolymers of N,N-dimethyl-3,5-methylenepiperidinium chloride and acrylamide, (v) copolymers of acrylamide and β-methacryloxyethyl trimethyl ammonium, (vi) polyethyleneimines, (vii) cationized cellulose, and (viii) condensates of polyamines and polyglycols; (C) from 1 to 30% by weight of at least one member selected from the group consisting of water-soluble anionic organic surfactant effective for washing hair and different from said anionic phosphoric acid ester, water-soluble nonionic organic surfactant effective for washing hair and water-soluble amphoteric organic surfactant effective for washing hair; and (D) the balance is essentially water, said shampoo composition having a pH of 4 to 8.
