Patent ID: 7307050

Claim:
An aqueous hair cleansing composition comprising the following components (A), (B) and (C): (A) from 5 to 30 wt. % of a sulfate surfactant having sulfates which are represented by the following formula (1): R—O—(C 2 H 4 O) n —SO 3 M (1), wherein, R represents a linear or branched C 8-18 alkyl or alkenyl group, n is 0 or a positive integer and M represents sodium or ammonium, and are composed of from 30 to 45 wt. % of a sulfate of the formula (1) in which n=0, from 18 to 27 wt. % of a sulfate of the formula (1) in which n=1, from 10 to 20 wt. % of a sulfate of the formula (1) in which n=2, and the balance of sulfates of the formula (1) in which n=3 or greater, and containing the sulfates of the formula (1) in which n=0 to 2 in a total amount of 70 wt. % or greater based on all the sulfates; (B) from 0.05 to 10 wt. % of an amino-modified silicone derivative represented by the following formula (3): wherein, each R 1 independently represents a monovalent hydrocarbon group, hydroxy group or alkoxy group, each R 2 independently represents a monovalent hydrocarbon group, each R 3 independently represents a divalent C 1-10 hydrocarbon group, each R 4 independently represents a group represented by the following formula (4) or (5): in which, each Y independently represents a hydrogen atom or a group —CH 2 —CH(OH)—R 3 —OH, each R 5 independently represents a hydrogen atom or a group —R 3 NY 2 , wherein Y and R 3 have the same meanings as defined above, with the proviso that the all of the Y do not represent a hydrogen atom simultaneously, a is from 25 to 1000 and b is from 1 to 200; and (C) from 0.1 to 10 wt. % of a silicone oil represented by the following formula (2): R′(CH 3 ) 2 SiO—[(CH 3 ) 2 SiO] m —Si(CH 3 ) 2 R′ (2), wherein, R′ represents a methyl or hydroxy group and m is from 50 to 20000, and existing as disperse particles having an average particle size of less than 50 μm.
