    Abstract: Process for treating keratin fibres with an ethylenicpolymer bearing a maleic anhydride group and a polyol The invention relates to a cosmetic process for treating keratin fibres, comprising the application to the keratin fibres of a mixture of a maleic anhydride ethylenic polymer, a liposoluble polyol and an amine catalyst; said maleic anhydride ethylenic polymer being obtained by polymerization of: (a) 25% to 95% by weight, relative to the total weight of monomers, of an ethylenic monomer bearing an at least C8 linear or branched alkyl group; (b) 5% to 25% by weight of maleic anhydride; (c) 0% to 50% by weight of additional (meth)acrylate monomer; and a step of heating the keratin fibres to a temperature ranging from 90° C. to 250° C. The invention also relates to the crosslinked polymer obtained by reacting said ethylenic polymer with said liposoluble polyol. The treated keratin fibres have good water-resistant fixing properties.

    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 anhydrous mixture of a cosmetic composition comprising a maleic anhydride block polymer and of an amino alkoxysilane compound; or the sequential application to the keratin materials of an anhydrous cosmetic composition comprising a maleic anhydride block polymer and of an anhydrous cosmetic composition containing an amino alkoxysilane, said block polymer comprising: a first block with a glass transition temperature (Tg) of greater than or equal to 40° C., obtained from a monomer CH2═C(R1)—COOR2 in which R1═H or methyl, R2═C4 to C12 cycloalkyl group; and a second block with a glass transition temperature (Tg) of less than or equal to 20° C. derived from a maleic anhydride monomer and from a monomer CH2═C(R1)—COOR3 in which R1═H or methyl, R3=linear or branched C1 to C6 unsubstituted alkyl group, with the exception of a tert-butyl group, or a methoxyethyl group. The invention also relates to the polymer bearing an alkoxysilane group obtained by reacting said block polymer with said amino alkoxysilane. The process makes it possible to obtain a non-tacky and transfer-resistant film-forming deposit that has good persistence and that is resistant to water, to oil and to sebum.

    Abstract: The invention relates to a block polymer comprising: a first block with a glass transition temperature (Tg) of greater than or equal to 40° C., obtained from a monomer CH2═C(R1)—COOR2, in which R1═H or methyl, R2═C4 to C12 cycloalkyl group; and a second block with a glass transition temperature (Tg) of less than or equal to 20° C. derived from a vinylphosphonic acid and from a monomer CH2═C(R1)—COOR3, in which R1═H or methyl, R3=linear or branched C1 to C6 unsubstituted alkyl group, with the exception of a tert-butyl group or a methoxyethyl group. The invention also relates to a cosmetic composition comprising such a block polymer, and also to a process for caring for or making up keratin materials using said block polymer combined with an additional compound chosen from polyamine compounds bearing several primary amine groups and/or secondary amine groups, amino alkoxysilanes, salts of divalent or trivalent metal ions, clays and metal oxides. The process makes it possible to obtain a film-forming deposit that has good resistance to water, to oil and to sebum. The film is also non-tacky and transfer-resistant.
