1: A cleansing composition comprising 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) a copolymer comprising monomers selected from the group consisting of (a1), (a2), and (a3) as constitutional units:
(a1) a monomer selected from the group consisting of acrylic acid and methacrylic acid,(a2) a monomer selected from the group consisting of an acrylic acid alkyl ester and a methacrylic acid alkyl ester, and(a3) a monomer selected from the group consisting of a polyoxyethylene alkyl ester of acrylic acid and a polyoxyethylene alkyl ester of methacrylic acid,and comprising 10 mol % or more of (a2) 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 having a constitutional unit represented by formula (1):wherein R identically or differently represents a group selected from the group consisting of (d) a hydrogen atom, a methyl group, an ethyl group, a hydroxyethyl group, and a hydroxypropyl group, (e) a substituent comprising a polyoxyalkylene group, (f) a sulfoalkyl group, (g) a carboxyalkyl group, and (h) a cationic substituent; Q identically or differently represents an alkylene group having 2 to 4 carbon atoms; a, b, and c identically or differently represent a number of 0 to 10; the QO groups, the R groups, or the numbers a, b, and c are identical or different in each repeating unit or between repeating units; and when each of the substituents (e) to (h) has a hydroxy group, the hydroxy group is optionally further substituted by any of other substituents (e) to (h), provided that at least one or more substituents (e) exist as R; and
(A-3) a polyether polycarbonate having a constitutional unit represented by formula (2):wherein A2 represents an alkylene group having 2 to 6 carbon atoms; n represents a number of 5 to 1,000 on average; p represents a number of 5 to 100 on average; and A2, having a number of (n×p) units, are identical or different;
(B) 1 to 50% by mass of an oil agent comprising (b1) and (b2):
(b1) an ether oil and(b2) a hydrocarbon oil having a viscosity of 18 mPa·s or lower at 30° C.; and (C) water, andcomprising
(D) no nonionic surfactant having HLB of 8 or more or less than 5% by mass of the nonionic surfactant. |
