Abstract
A cosmetic composition having improved transfer resistance comprising: a) from about 0.1-60% by weight of trimethylated silica, b) from about 0.1-60% by weight of a volatile solvent having a viscosity of 0.5 to 100 centipoise at 25.degree. C., c) 0.1-60% by weight of a nonvolatile oil having a viscosity of 200 to 1,000,000 centipoise at 25.degree. C. d) 0.1-80% of a cosmetically acceptable carrier.
Claims16
A transfer resistant lipstick composition comprising, by weight of the total composition:
- (a) from about 0.1-60% trimethylated silica having a silanol endgroup density of 0.5 to 5 micromol/m.sup.2 formed by the reaction of trimethylchlorosilane and an aqueous silica sol,
