Abstract: The invention relates to a copolymer resulting from the polymerization of: (a) 50% to 90% by weight, of the total weight of monomers, of isobornyl (meth)acrylate, (b) 1% to 50% by weight of maleic anhydride, (c) 0% to 49% by weight of additional (meth)acrylate monomer chosen from: (i) saturated or unsaturated and linear or branched C1-C20 alkyl (meth)acrylates, the alkyl being optionally interrupted by one or more nonadjacent heteroatoms chosen from O or S or by an NR group, R being a C1-C4 alkyl group, optionally substituted by a phenyl or furfuryl group; (ii) saturated C4-C8 cycloalkyl (meth)acrylates, the cycloalkyl being optionally interrupted by O or NH. The invention also relates to a composition comprising said copolymer in a physiologically acceptable medium. The invention also relates to a cosmetic method for caring for or making up the skin or the lips, comprising the topical application, to the skin or the lips, of a cosmetic composition comprising said copolymer.

Abstract: The invention relates to a cosmetic process for caring for or making up keratin materials, comprising either the topical application to the keratin materials of an (extemporaneous) anhydrous mixture of a cosmetic composition comprising a maleic anhydride acrylic polymer and of an amino alkoxysilane compound (I); or the sequential application to the keratin materials of an anhydrous cosmetic composition comprising a maleic anhydride acrylic polymer and of an amino alkoxysilane compound (I), wherein said maleic anhydride acrylic polymer is obtained by polymerization of: (a) 50% to 90% by weight, relative to the total weight of monomers, of isobornyl (meth)acrylate (b) 1% to 50% by weight of maleic anhydride (c) 0% to 49% by weight of additional (meth)acrylate monomer; said amino alkoxysilane having the formula (I): R—NH—R1Si(OR2)z(R3)x??(I) in which: R1 is a C1-C20 hydrocarbon-based divalent group, R=H or a C1-C4 alkyl group, R2 and R3 represent an alkyl group comprising from 1 to 6 carbon atoms; z d

Abstract: The present invention relates to a linear ethylenic block copolymer comprising in each block at least one ionic hydrophilic unit, which may be different from one block to another, the said ionic hydrophilic unit being present in each block in a proportion of from 2% to 100% by weight relative to the weight of the said block. The invention also relates to a cosmetic or pharmaceutical composition comprising such a copolymer, and also to a cosmetic process for making up or caring for keratin materials using the said composition.
