Abstract: The present invention relates to a composition comprising particles of at least one polymer that is surface-stabilized with a stabilizer, the polymer of the particles being a C1-C4 alkyl (meth)acrylate polymer; the stabilizer being an isobornyl (meth)acrylate polymer chosen from isobornyl (meth)acrylate homopolymer and statistical copolymers of isobornyl (meth)acrylate and of C1-C4 alkyl (meth)acrylate present in an isobornyl (meth)acrylate/C1-C4 alkyl (meth)acrylate weight ratio of greater than 4, at least one hydrocarbon-based oil and at least one amorphous hydrocarbon-based block copolymer obtained by polymerization of at least one monomer of unsaturated hydrocarbon type comprising 2 to 5 carbon atoms and containing one or two ethylenic unsaturations. The invention also relates to a process for making up and/or caring for keratin materials, in which said composition is applied.

Abstract: Composition, preferably a cosmetic composition, for caring for and/or making up keratin materials, preferably the eyelashes and/or the eyebrows, comprising: —(1) at least one linear fatty acid monoester of formula (I): R1—O—R2 in which R1 and R2 are linear and saturated and have, independently of one another, a number of carbon atoms greater than or equal to 20, with R1 representing an acyl radical, and R2 representing an alkyl radical, and —(2) at least one fatty acid having from 14 carbon atoms to less than 20 carbon atoms, —(3) at least one organic base, in particular derived from an alkanolamine, capable of at least partially neutralizing at least one fatty acid (2), and —(4) at least one fatty alcohol preferably chosen from C14-C30 fatty alcohols, better still chosen from the linear and saturated C14-C24, even better still C14-C20, fatty alcohols, and —(5) water.

Abstract: The present invention relates to a composition, especially a cosmetic composition, for caring for and/or making up keratin materials, comprising at least: a non-aqueous medium containing at least one hydrocarbon-based oil, particles of at least one polymer that is surface-stabilized with a stabilizer, the polymer of the particles being a C1-C4 alkyl (meth) acrylate polymer; the stabilizer being an isobornyl (meth)acrylate polymer chosen from isobornyl (meth)acrylate homopolymer and statistical copolymers of isobornyl (meth)acrylate and of C1-C4 alkyl (meth)acrylate present in an isobornyl (meth)acrylate/C1-C4 alkyl (meth)acrylate weight ratio of greater than 4; and a hydrophobic film-forming polymer chosen from block ethylenic copolymers and hydrocarbon-based resins, and. mixtures thereof. The present invention also relates to a cosmetic process for making up and/or caring for keratin materials, and to the use of a dispersion of particles of at least one polymer that is surface-stabilized with a stabilizer in a non-aqueous medium containing at least one hydrocarbon-based oil, for preparing a mascara or eyeliner composition.

Abstract: The present invention relates to a composition, preferably a cosmetic composition, in particular for coating keratin fibers such as the eyelashes, comprising:—an aqueous phase,—a lamellar phase Lβ formed by an aqueous phase-structuring surfactant system, said surfactant system comprising a content of surfactant(s) of greater than or equal to 15% by weight relative to the total weight of the composition,—at least one (poly)vinylpyrrolidone hydrophilic polymer present in a content of greater than or equal to 3% by weight of solids relative to the total weight of the composition, the hydrophilic polymer(s) having a weight-average molecular mass Mw ranging from 1500 to 500 000 g/mol. The present invention also relates to a process for coating keratin fibers.
