    • The invention discloses the use in and for the preparation of cosmetic and dermatological compositions of one copolymer obtainable by the copolymerisation of a mixture of monomers comprising: (a)5 to 25 wt.% of at least one ethylenically unsaturated monomer (A) comprising at least one carboxylic acid function; (b) 3 to 30 wt.% of at least one monomer (B) of formula (I): H2C=C(R1)-COOR2 in which R1 represents a hydrogen atom or a methyl radical; R2 represents a linear or branched or cyclic, saturated or unsaturated or aromatic alkyl radical, having 8 to 40 carbon atoms; (c) of at least one monomer (C) selected from the group constituted by tertio-butyl methacrylate, tertio-butyl acrylate and their mixtures, in a proportion higher than 50 %, such that the polymer glass transition temperature (Tg) is at least 15 DEG C, the weight percentages being computed with respect to the total amount of monomer used. The invention also concerns the cosmetic and dermatological compositions used.
    • 本发明公开了在一种共聚物的化妆品和皮肤病学组合物的制备中的用途,该共聚物可通过共聚单体混合物而得到,该混合物包含:(a)5至25重量%的至少一种烯属不饱和单体(A) 至少一种羧酸功能; (b)3至30重量%的至少一种式(I)单体(B):其中R 1表示氢原子或甲基的H 2 C = C(R 1)-COOR 2; R 2表示具有8至40个碳原子的直链或支链或环状,饱和或不饱和或芳族烷基; (c)至少一种选自甲基丙烯酸叔丁酯,丙烯酸叔丁酯及其混合物的组分中的至少一种单体(C)的比例高于50%,使得聚合物玻璃化转变温度(Tg)在 至少15℃,相对于所用单体的总量计算重量百分数。 本发明还涉及使用的化妆品和皮肤病学组合物。
