1. A cosmetic composition for use on lips, comprising:
A. a Pickering dispersion of a hydrogel in oil, comprising:
(i) ethylenic polymeric core particles forming the hydrogel, each ethylenic polymeric core particle obtained by polymerization of monomers of:
(a) (C1-C4) alkyl (C1-C4) (alkyl) acrylate in which the (C1-C4) alkyl group(s) are optionally substituted by one or more hydroxy groups and/or (di) (C1-C4) (alkyl) amino groups;
(b) poly [oxy (C1-C4) alkylene] (C1-C4) (alkyl) acrylate; and/or
(c) ethylenic monomers comprising one or more groups selected from carboxy, anhydride, phosphoric acid, and sulfonic acid;
(ii) a polymeric stabilizing agent chosen from:
(d) ethylenic polymers of (C1-C6) (alkyl) acrylate of (C3-C12) cycloalkyl monomers; and/or
(e) copolymers of ethylenic monomers of (C1-C6) (C3-C12) cycloalkyl (alkyl) acrylate and (C1-C4) alkyl (C1-C4) (alkyl) acrylate; and
(iii) a fatty substance that is liquid at 20° C. and 1 atmosphere;
B. a transfer-resistant film former.
