The present invention provides a cleansing composition comprising the following components (A), (B), and (C): (A) 0.001 to 5% by mass of a polymer selected from the group consisting of (A-1), (A-2), and (A-3): (A-1) an acrylic copolymer comprising 10 mol % or more of a monomer selected from the group consisting of an acrylic acid alkyl ester and a methacrylic acid alkyl ester, as represented by mol % based on the total monomers; (A-2) a polysaccharide derivative having a polyoxyalkylene chain having an average molecular weight of 300 to 100,000; and (A-3) a polyether polycarbonate; (B) 1 to 50% by mass of one or two or more oil agents selected from the group consisting of (b1) and (b2): (b1) an ether oil and (b2) a hydrocarbon oil having a viscosity of 18 mPa&#xb7;s or lower at 30&#xb0; C.; and (C) water, and comprising (D) no nonionic surfactant having HLB of 8 or more or less than 5% by mass of the nonionic surfactant.

Cleansing composition

Provided is a skin cleansing composition comprising the following components (A), (B), (C), (D), and (E): (A) 0.1 to 25 mass % of an ether oil which is in a liquid state at 25&#xb0; C., (B) 0.003 to 1 mass % of a water-soluble polymer comprising acrylic acid or methacrylic acid as a constitutional unit, (C) 1 to 30 mass % of a hydrocarbon oil having a viscosity of 15 mPa&#xb7;s or lower at 30&#xb0; C., (D) 60 to 95 mass % of water, and (E) 0.49 mass % or less of a nonionic surfactant having an HLB of larger than 9, wherein the mass ratio of the component (B) to the component (A), (B)/(A) is from 0.0001 to 0.1, and the mass ratio between the component (A) and the component (C), (A)/((A)+(C)) is from 0.05 to 0.9.

Skin cleansing composition

A skin cleansing agent composition of the present invention contains an isotropic liquid phase, which is a bicontinuous structure, and containing: 15 to 30 mass % of a nonionic surfactant having HLB of higher than 9 and equal to or lower than 20; 1 to 15 mass % of a nonionic surfactant having HLB of equal to or higher than 5 and equal to or lower than 9; 10 to 40 mass % of an oil agent exhibiting a viscosity at 30 degrees C. of equal to or lower than 30 mPa&#xb7;s; 10 to 40 mass % of a water-soluble solvent having 3 or more of hydroxyl groups in single molecule; 10 to 30 mass % of a water-soluble solvent having 1 or 2 hydroxyl group(s) in single molecule; 0.05 to 1.0 mass % of a water-soluble polymer containing (meta)acrylic acid as a configuration unit and/or an acryloyl methyl taurate-vinylpyrrolidone copolymer; 0.001 to 2.0 mass % of a water-soluble inorganic salt and/or an organic salt having 1 to 8 carbon atoms; and water.
