PCT No. PCT/FR97/01165 Sec. 371 Date Apr. 17, 1998 Sec. 102(e) Date Apr. 17, 1998 PCT Filed Jun. 30, 1997 PCT Pub. No. WO98/00096 PCT Pub. Date Jan. 8, 1998The subject of the present invention is the use, in, and for the preparation of, cosmetic or dermatological compositions, of a copolymer which can be obtained by copolymerization of a monomer mixture comprising: (a) from 5 to 25% by weight of at least one monomer (A) with ethylenic unsaturation containing at least one carboxylic acid function; (b) from 3 to 30% by weight of at least one monomer (B) of formula (I):H2C=C(R1)-COOR2(I) in which R1 denotes a hydrogen atom or a methyl radical, R2 denotes a saturated or unsaturated, linear or branched or cyclic alkyl radical or an aromatic radical, having from 8 to 40 carbon atoms, (c) at least one monomer (C) chosen from the group consisting of tert-butyl methacrylate, tert-butyl acrylate and mixtures thereof, in a proportion greater than 50%, such that the glass transition (Tg) of the polymer is greater than or equal to 15 DEG C., the weight percentages being calculated relative to the total amount of monomers used, as well as to the cosmetic or dermatological compositions used. |
