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.

Process for treating keratin fibers employing an anhydride acrylic polymer in oily dispersion and an amine compound

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 C-Calkyl (meth)acrylate polymer; the stabilizer being a C-Calkyl (meth)acrylate polymer and optionally of a 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.

Dispersion of polymer particles in a non-aqueous medium and cosmetic use thereof

Provided is a dispersion of polymer particles, wherein the polymer is surface-stabilized with a stabilizer in a non-aqueous medium containing at least one hydrocarbon-based oil. The polymer of the particles is a C1-C4 alkyl (meth)acrylate polymer; and the stabilizer is an isobornyl (meth)acrylate polymer. Also provided is a composition that comprises the dispersion of polymer particles. The dispersion can be used as a cosmetic for caring for and making up of keratin materials.
