Abstract: Disclosed herein are: a copolymer obtained by causing a diglycerin fatty acid ester represented by the following general formula (1) and isophorone diisocyanate to react with each other, the copolymer having a weight-average molecular weight of from 3,500 to 100,000; and a cosmetic composition including the copolymer: where R1 represents an alkyl group having 8 to 24 carbon atoms or an alkenyl group having 8 to 24 carbon atoms, X1 to X3 each independently represent a hydrogen atom or a group represented by —C(═O)R2, and R2 represents an alkyl group having 8 to 24 carbon atoms or an alkenyl group having 8 to 24 carbon atoms, provided that at least one of X1 to X3 represents a hydrogen atom.
