Claims4
A cosmetic composition comprising:
- A) a mixture of:
- (1) an organosiloxane resin which is solid at about 25° C., has a molecular weight range of from about 1,000 to about 10,000 grams/mole, is soluble in organic solvents, and comprises R3SiO1/2 “M” units, R2SiO “D” units, RSiO3/2 “T” units, SiO2 “Q” units and mixtures thereof in a ratio selected to satisfy the relationship RnSiO(4−n)/2, wherein is about 1.2 and R is a methyl group and wherein the ratio of “M” to “Q” groups is about 0.7;
- and
- (2) dimethicone gum having a viscosity of 2,500,000 cSt at 25° C.;
- B) a volatile carrier;
- and
- C) a pigment;
- wherein the ratio of organosiloxane resin to dimethicone gum is from about 1:10 to about 3.5:1;
- and
- wherein the ratio of dimethicone gum to pigment is from about 1:1 to about 30:1;
- said composition comprising no more than about 2% by weight of waxes.
