Oily dispersion comprising a polymeric particle and a stabilizer bearing a C9-C22 alkyl group, and process for treating keratin materials using the oily dispersion

An oily dispersion comprising:

• i) one or more particles including one or more polymers chosen from:
• a) ethylenic homopolymers of (C1-C4)alkyl (C1-C4)(alkyl)acrylate;
• b) ethylenic copolymers of b1) (C1-C4)alkyl (C1-C4)(alkyl)acrylate, and of b2) ethylenic monomers comprising one or more carboxyl, anhydride, phosphoric acid, sulfonic acid and/or aryl groups;
• and
• ii) one or more polymeric stabilizers chosen from:
• d) ethylenic homopolymers of (C9-C22)alkyl (C1-C6)(alkyl)acrylate;
• and
• e) ethylenic copolymers of (C9-C22)alkyl (C1-C6)(alkyl)acrylate and of (C1-C4)alkyl (C1-C4)(alkyl)acrylate, wherein the ethylenic copolymers have a weight ratio of the (C9-C22)alkyl (C1-C6)(alkyl)acrylate/(C1-C4)alkyl (C1-C4)(alkyl)acrylate of greater than 4;
• iii) one or more hydrocarbon-based liquid fatty substances;
• and
• iv) optionally one or more cosmetic active agents chosen from f) dyes, g) pigments;
• h) active agents for caring for keratin materials, and j) UV (A) and/or (B) screening agents, and m) mixtures thereof.
