<p>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 °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.</p> |
