Abstract:
A cosmetic comprising a raw material for a cosmetic and a copolymer, said copolymer comprising(A) 5 to 95% by weight of repeating units derived from a fluorine-containing (meth)acrylate, and (B) 95 to 5% by weight of repeating units derived from at least one fluorine-free monomer selected from the group consisting of a silicone macromonomer, a polyalkylene glycol (meth)acrylate, an alkyl (meth)acrylate macromonomer, and an alkyl (meth)acrylate, wherein the copolymer comprises: (i) a fluorine-containing (meth)acrylate and a silicone macromonomer, (ii) a fluorine-containing (meth)acrylate and a polyalkylene glycol (meth)acrylate, (iii) a fluorine-containing (meth)acrylate and an alkyl (meth)acrylate macromonomer, (iv) a fluorine-containing (meth)acrylate and a C1-4 alkyl-containing alkyl (meth)acrylate, (v) a fluorine-containing (meth)acrylate, a silicone macromonomer, and a C1-4 alkyl-containing alkyl (meth)acrylate, or (vi) a fluorine-containing (meth)acrylate, a silicone macromonomer, and an alkyl (meth)acrylate macromonomer; wherein the copolymer is dissolved or dispersed in a medium, and the medium is a hydrofluoroether represented by the general formula: CnHmFlOCxHyFz wherein n is a number of 1 to 12, m is a number of 0 to 25, l is a number of 0 to 11, m+1 is equal to 2n+1, x is a number of 1 to 12, y is a number of 0 to 25, z is a number of 0 to 11, and y+z is equal to 2x+1, with the proviso that m and y are not simultaneously 0 and that 1 and z are not simultaneously 0.
