    • The present invention concerns the use, for the production of a cosmetic or dermatological composition comprising at least one aqueous phase, of a branched or crosslinked polymer obtained by polymerisation of an aqueous solution of one or a plurality of monomers in water-in-oil inverse emulsion, at least one of the monomers used being an acrylic monomers and one or a plurality of the monomers used being a monomer carrying at least one weak acid function, the molar percentage of monomers carrying at least one weak acid function relative to all the monomers used being at least equal to 30%, characterised in that: i) polymerisation is carried out with a concentration of all the monomers in aqueous solution belonging to the range of 1.3 mmol to 3.6 mmol per gram of aqueous solution, ii) during polymérisation, at most 20% of the acid functions present on the monomers have at least one acid function in neutralised form; the cosmetic and dermatological compositions obtained in this way and the uses thereof for the cosmetic and dermatological treatment of keratin materials.
    • 一种化妆品或皮肤病学组合物包含至少一种wässrige相的支链或交联的聚合物的,由一个或多个单体在水包油反相乳液的水溶液中的聚合而得到,所使用的单体中的至少一种是丙烯酸类 单体和一种或多种单体的用过作为一个单体轴承至少一种弱酸功能,至少一个相对于所有单体的弱酸官能用于为至少30摩尔%的单体轴承的摩尔百分比。 聚合反应在溶液wässrige趴在范围为每克wässrige溶液的1.3〜3.6毫摩尔毫摩尔所有单体的浓度下进行。 在聚合过程中,存在于具有至少一个酸官能团单体中的酸官能团至多20%是在中和的形式。该组合物用于治疗角质材料。
