Abstract
A cosmetic composition may be utilized to provide improved wear and transfer resistance. The cosmetic composition may include a (i) hydrogel dispersion in oil, the hydrogel having an ethylenic polymeric core, as well as (ii) a transfer-resistant film former, (iii) a hydrophilic active agent incorporated into the ethylenic polymeric core, or (iv) both (ii) and (iii). The dispersion may include a plurality of ethylenic polymeric core particles dispersed in a fatty substance that is liquid at 20° C. and 1 atmosphere that also includes a polymeric stabilizing agent.
Claims19
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.
