Glow and sunless tanning color enhancement by cationic copolymers
A cosmetic composition for sunless tanning or imparting glow to skin is herein described. The composition includes from about 0.1 to about 20% by weight of a tanning agent and from 0.1 to 20% by weight of a crosslinked cationic copolymer having a monomer unit which is a methacryloylethyl or acryloylethyl tri(C 1 -C 3 alkyl)ammonium salt. The crosslinked cationic copolymer is a color enhancing agent which improves color intensity and avoids streaking of the developing tan/glow.
1. A cosmetic product for imparting a glow or sunless tan to skin comprising:
(i) from about 0.1 to about 20% by weight of a tanning agent which is reactive with skin to produce a tan color;
(ii) from about 0.1 to about 20% by weight of a color enhancing agent which is a crosslinked cationic copolymer that is acrylamide/acryloylethyl trimethylammonium chloride/tris(hydroxymethyl)acrylamidomethane copolymer; and
(iii) a cosmetically acceptable carrier.
2. The composition according to claim 1 wherein the tanning agent is dihydroxyacetone.
3. The product according to claim 1 wherein the crosslinked cationic copolymer is present in an amount from about 0.5 to about 10% by weight of the composition.
4. The product according to claim 1 wherein the tanning agent is present in an amount from about 0.5 to about 10% by weight of the composition.
5. The product according to claim 1 further comprising from about 0.01 to about 5% by weight of a monomeric quaternary ammonium salt.
6. The product according to claim 5 wherein the monomeric quaternary ammonium salt is a di(C 12 -C 22 ) fatty alkyl substituted ammonium salt.
7. The product according to claim 5 wherein the monomeric quatemary ammonium salt is distearyl dimonium chloride.
