Provided is a skin detergent composition containing a polyoxyethylene alkyl ether sulfate or an alkyl sulfate which composition is high in foam viscosity and creamy in foam quality. The skin detergent composition contains the following components (A), (B) and (C): (A) a polyoxyethylene alkyl ether sulfate or an alkyl sulfate represented by a general formula (1): €ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒR 1 O(CH 2 CH 2 O) n SO 3 M€ƒ€ƒ€ƒ€ƒ€ƒ(1)； (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, at least one cationic group-containing vinyl monomer, 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； (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 to 14% by weight.
