Abstract: The disclosure relates to a process for treating keratin fibers comprising, in a first stage, the application to said fibers of an oily dispersion (A) comprising i) particles of copolymers of alkyl acrylates and anhydride acrylics, ii) stabilizers, and iii) one or more hydrocarbon-based oils, and then, in a second stage, the application to said fibers of a composition (B) comprising iv) one or more amine compounds; or the application to said fibers of an oily dispersion (D) comprising said ingredients i), ii), iii) and iv), wherein v) one or more dye(s) and/or pigment(s) may be in the dispersion (A) or (D), in a composition (B), and/or in another composition (C). The disclosure further relates to a multi-compartment kit comprising the ingredients i) to v), and an oily dispersion (A) comprising v) the one or more dyes and/or pigments.

Abstract: The present invention relates to a process for treating keratin materials, preferably human skin, in particular the lips, preferably in at least two steps involving, in a first stage, the application to said materials of an oily dispersion (A) comprising i) particles of copolymers of alkyl acrylates and of anhydride acrylics, ii) stabilizers, iii) one or more hydrocarbon-based oils; and then, in a second stage, the application to said materials of a composition (B) comprising iv) one or more amine compounds, it being understood that the process of the invention uses v) one or more cosmetic active agents chosen from a) pigments, b) active agents for caring for the skin, and c) UV-screening agents and also d) mixtures thereof; ingredients a) to d) possibly being found in composition (A), and/or in composition (B), and/or in another composition (C).
The process of the invention makes it possible to obtain a treatment of said keratin materials that is notably resistant to sweat, to shower gels, to water and to fatty substances, in particular plant or animal food oils, and more particularly plant oils such as olive oil, sunflower oil, walnut oil, hazelnut oil, etc.
The keratin material treatment process of the present patent application is also suitable for making up the skin or the lips, such as foundations and lipsticks.

Abstract: The invention relates to a dispersion of polymer particles stabilized with a stabilizer in a nonaqueous medium containing at least one hydrocarbon-based oil, the polymer of the particles being a C1-C4 alkyl (meth)acrylate polymer; the stabilizer being a C1-C4 alkyl (meth)acrylate polymer and optionally of a silicone macromonomer (I): the stabilizer being a polymer comprising from 50% to 100% by weight, relative to the total weight of the stabilizer, of C8-C22 alkyl acrylate, from 0 to 50% by weight of C1-C4 alkyl (meth)acrylate and optionally silicone macromonomer (I). The invention also relates to the composition comprising said dispersion of polymer particles.Cosmetic use for caring for and making up keratin materials.
