Claims
- 1. An anhydrous composition in the form of a makeup for application to skin or lips that provides sunscreen protection comprising, by weight of the total composition:about 0.1-30% trimethylated silica, about 0.1-40% 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;0.1-30% nonvolatile oil, and 0.1-70% particulate matter comprising titanium dioxide.
- 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 4 wherein the trimethylated silica is found in a cosmetic fluid composition comprising about equal parts of volatile solvent and trimethylated silica.
- 6. The compsition of claim 1 wherein the volatile solvent is selected from the group consisting of 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 wax is tribehenin.
- 16. The composition of claim 1 further comprising silica, methyl, and methyl vinyl siloxane copolymer.
- 17. An anhydrous sunscreen makeup 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, 0.1-60% 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.
