A cosmetic is characterized by containing a polymer which is produced by polymerizing a fluorine atom-containing monomer represented by formula (I) (wherein R1 represents a hydrogen atom or a methyl group； R2 represents a hydrogen atom or a fluorine atom； m represents an integer of 0 or 1 to 4； and n represents an integer of 1 to 12), (B) a betaine monomer represented by formula (II) (wherein R3 represents a hydrogen atom or a methyl group； R4 and R5 independently represent a hydrogen atom or an alkyl group having 1 to 4 carbon atoms； p represents an integer of 1 to 4； and q represents an integer of 1 to 4) and (C) a monomer component containing an alkyl (meth)acrylate represented by formula (III) (wherein R6 represents a hydrogen atom or a methyl group； and R7 represents an alkyl group having 8 to 22 carbon atoms) with one another.本發明提供一種兼具撥水性及撥油性，且耐水性及耐皮脂性優異之化粧料。該化粧料之特徵在於含有聚合物，該聚合物係使含有以下者之單體成分聚合而成：(A)式(I)所表示之含有氟原子之單體，(R1表示氫原子或甲基，R2表示氫原子或氟原子，m表示0或1~4之整數，n表示1~12之整數)；(B)式(II)所表示之甜菜鹼單體，(R3表示氫原子或甲基，R4及R5分別獨立地表示氫原子或碳數1~4之烷基，p表示1~4之整數，q表示1~4之整數)；及(C)式(III)所表示之(甲基)丙烯酸烷基酯，(R6表示氫原子或甲基，R7表示碳數8~22之烷基)。
