Patent ID: 7964545

Claim:
A skin detergent composition comprising the following components (A), (B) and (C): (A) a polyoxyethylene alkyl ether sulfate or an alkyl sulfate represented by a general formula (1): R 1 O(CH 2 CH 2 O) n SO 3 M (1) wherein R 1 represents a straight chain or branched chain, alkyl or alkenyl group having 8 to 18 carbon atoms, an average addition number of moles n represents a number of 0 to 5, and M represents an alkali metal atom, an alkanolamine or ammonium; (B) myristyl alcohol; (C) one or more cationic polymers selected from the group consisting of the following (C-1) to (C-4): (C-1) a cationic group-containing copolymer obtained by a radical polymerization including as essential constituent monomers at least one nonionic group-containing vinyl monomer represented by a general formula (I) or (II), at least one cationic group-containing vinyl monomer represented by a general formula (III) or (IV), and at least one crosslinkable vinyl monomer having in the molecule thereof at least two groups selected from a vinyl group, an acryloyl group, a methacryloyl group and an allyl group: wherein R 11 represents a hydrogen atom or a methyl group, and R 12 and R 13 are the same or different and each represent a hydrogen atom or a straight chain or branched chain, alkyl or alkenyl group having 1 to 4 carbon atoms, wherein R 11 represents the same meaning as above, A 1 and A 2 are the same or different and each represent a group represented by a formula —(CH 2 ) m — with the proviso that m represents an integer of 2 to 6, and B represents a group —O— or —CH 2 —, wherein R 11 represents the same meaning as above, R 14 and R 15 are the same or different and each represent an alkyl or alkenyl group having 1 to 4 carbon atoms, R 16 represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms, Y represents a group —O—, —NH—, —CH 2 — or —O—CH 2 CH(OH)—, Z represents a straight chain or branched chain alkylene group having 1 to 4 carbon atoms with the proviso that this group has 0 to 3 carbon atoms when Y is —CH 2 —, and X − represents a conjugate base of an acid, a halide ion or an alkyl sulfate group having 1 to 4 carbon atoms, wherein R 17 and R 18 are the same or different and each represent a hydrogen atom or a methyl group, R 19 and R 20 are the same or different and each represent a hydrogen atom or an alkyl group having 1 to 4 carbon atoms, and X − represents the same meaning as above; (C-2) a cationized cellulose derivative; (C-3) a cationized guar gum derivative; and (C-4) a diallyl quaternary ammonium salt polymer or a diallyl quaternary ammonium salt/acrylamide copolymer, wherein the weight ratio of the component (A) to the component (B) is (A)/(B)=15/0.1 to 15/4, the weight ratio of the component (A) to the component (C) is (A)/(C)=15/0.05 to 15/3, the weight ratio of the component (B) to the component (C) is (B)/(C)=1/0.05 to 1/1, and the content of the component (B) is more than 1 up to and including 14% by weight.
