Claims
- 1. An anhydrous pigmented composition comprising, by weight of the total composition:0.1-20% trimethylated silica, 1-30% volatile solvent volatile solvent having a viscosity of 0.5 to 20 centipoise at 25° C. selected from the group consisting of a cyclic silicone having the formula: wherein n=1-7; a linear silicone having the formula:(CH3)3Si—O—[—Si(CH3)2—O—]n—Si(CH3)3 wherein n=0-6; a straight or branched chain hydrocarbon having 8-20 carbon atoms; ethanol; and mixtures thereof;0.1-40% nonvolatile oil, and 0.1-60% particulate matter having a particle size of 0.02 to 100 microns wherein at least a portion of the particulates are surface treated with lecithin.
- 2. The composition of claim 1 wherein the trimethylated silica has a silanol endgroup density of 0.5 to 5 micromol/m2.
- 3. The composition of claim 1 wherein the trimethylated silica is in the form of spherical particles.
- 4. The composition of claim 1 wherein the trimethylated silica has a particle size of 0.5 to 100 millimicrons.
- 5. The composition of claim 1 wherein the trimethylated silica is found in a cosmetic fluid composition comprising about equal parts of volatile solvent and trimethylated silica.
- 6. The composition of claim 1 wherein the volatile solvent is an cyclomethicone, a straight or branched chain hydrocarbon having 8-20 carbon atoms, and mixtures thereof.
- 7. The composition of claim 1 wherein the nonvolatile oil comprises an oil selected from the group consisting of dimethicone, dimethicone copolyol, and mixtures thereof.
- 8. The composition of claim 1 wherein the nonvolatile oil comprises esters.
- 9. The composition of claim 8 wherein the nonvolatile oil comprises esters and an oil selected from the group consisting of dimethicone, dimethicone copolyol, and mixtures thereof.
- 10. The composition of claim 1 wherein the particulate matter comprises, in addition to titanium dioxide, one or more pigments or powders having a particle size of 0.02 to 200 microns.
- 11. The composition of claim 10 wherein the pigments comprise inorganic pigments, organic pigments, or mixtures thereof.
- 12. The composition of claim 10 wherein the particulate matter further comprises zinc oxide.
- 13. The composition of claim 10 wherein the particulate matter further comprises boron nitride.
- 14. The composition of claim 1 further comprising a wax.
- 15. The composition of claim 14 wherein the was is polyethylene.
- 16. The composition of claim 1 which is selected from the group consisting of eyeshadow and blush.
- 17. An anhydrous pigmented cosmetic composition comprising, by weight of the total composition:1-30% trimethylated silica having a silanol endgroup density of 0.5 to 5 micromol/m2, 1-40% volatile solvent having a viscosity of 0.5 to 20 centipoise at 25° C., selected from the group consisting of a cyclomethicone, hexamethyldisiloxane, isododecane, and mixtures thereof, 05-30% of a nonvolatile oil selected from the group consisting of dimethicone, dimethicone copolyol, and mixtures thereof; and 0.1-70% particulate matter comprising titanium dioxide and an ingredient selected from the group consisting of zinc oxide, boron nitride, silica, mica, iron oxides, and mixtures thereof wherein one or more of the particulates are surface treated with lecithin.
