Patent ID: 8530398

Claim:
An aqueous hair cleansing agent comprising components (A), (B), (C) and (D): (A) from 1 to 30 weight % of a sulfate anionic surfactant represented by formula (1) R 1 O(CH 2 CH 2 O) n SO 3 M (1) wherein, in formula (1), R 1 represents an alkyl group or alkenyl group having 10 to 18 carbon atoms, M represents an alkali metal, an alkaline earth metal, ammonium, an alkanolamine, or a basic amino acid, and n represents a number from 0 to 5 as a mass average; (B) from 0.1 to 10 weight % of a polyoxypropylene alkyl ether nonionic surfactant represented by formula (2), R 2 O(CH 2 CH(CH 3 )O) m H (2) wherein in formula (2), R 2 represents a straight chain or branched alkyl group or alkenyl group having 8 to 10 carbon atoms, and m represents a number from 0.5 to 4 as a mass average; (C) from 0.1 to 5 weight % of a monoalkyl glyceryl ether or monoalkenyl glyceryl ether nonionic surfactant having an alkyl group or alkenyl group having 4 to 12 carbon atoms; and (D) from 0.1 to 10 weight % of an alkylhydroxysulfobetaine amphoteric surfactant represented by formula (3) wherein, in formula (3), R 3 represents an alkyl group having 10 to 14 carbon atoms, and wherein the mass ratio of components (B) and (D), (B)/(D), is 3/2 to 1/4.
