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.
