Provided is a means for increasing the strength of a formed film in a copolymer obtained by copolymerizing a monomer having a fluorohydrocarbon structure and a monomer having a hydrophilic group. The composition includes at least one structural unit derived from a monomer represented by the general formula (I) and at least one structural unit derived from a monomer represented by the general formula (II), and Wherein the content of the structural unit derived from the monomer represented by the general formula (I) is from 5 to 65% by weight of all the structural units, in terms of polyethylene glycol measured by GPC (gel permeation chromatography). A copolymer having a number average molecular weight of 100,000 to 100,000 is provided, and is contained in a cosmetic or the like.
