(57) [Summary] [Structure] A monoalkenyl ether represented by the following general formula (1), another copolymerizable compound, and a difluoro peroxide represented by the following general formula (2) or (3). The reaction product with alkanoyl has a reaction molar ratio of the compound represented by the general formula (2) or (3) to the compound represented by the general formula (1): 1: 0.1 to 1: 5,000, A cosmetic containing a reaction product in which the polymerizable compound is 50 mol% or less of the compound of the general formula (1) and the number average molecular weight is 1,000 to 1,000,000. [Chemical 1] [Chemical 2] [Chemical 3] [Effect] Since it contains a reaction product having a fluoroalkyl group as a carbon-carbon bond, it is non-greasy, has a light feel, has a high degree of adhesion and holding power, and gives a natural appearance. |
