Claims
- 1. A cosmetic composition comprising an oil component and a particulate matter component, the improvement wherein the composition additionally contains an uncrosslinked synthetic polymer consisting of polymerized ethylenically unsaturated monomers A and B, wherein:
- (a) A is selected from the group consisting of methacrylate ester monomers which, if polymerized, would yield a polymer having a glass transition temperature of -10 to 75.degree. C.; and
- (b) B is selected from the group consisting of methacrylate ester monomers which, if polymerized, would yield a polymer having a glass transition temperature in the range of about 76 to 120.degree. C.,
- said synthetic polymer having a glass transition temperature in the range of about 20 to 105.degree. C.
- 2. The composition of claim 1 wherein the polymer contains two or more different A monomers.
- 3. The composition of claim 1 wherein the polymer contains two or more different B monomers.
- 4. The composition of claim 1 wherein the A and B monomers, if polymerized to a molecular weight average of 20,000 would yield polymers having a glass transition temperature of -10 to 75.degree. C., and 76 to 120.degree. C., respectively.
- 5. The composition of claim 1 wherein the A monomer is selected from the group consisting of methacrylic acid esters.
- 6. The composition of claim 5 wherein the A monomer is an aliphatic ester of methacrylic acid.
- 7. The composition of claim 6 wherein the A monomer is methacrylic acid esterified with an aliphatic alcohol of 2 to 8 carbon atoms.
- 8. The composition of claim 7 wherein the aliphatic alcohol has 1 or 2 hydroxy groups.
- 9. The composition of claim 6 wherein the A monomer is selected from the group consisting of isobutylmethacrylate, n-butylmethacrylate, hydroxyethylmethacrylate, and ethylhexylmethacrylate, and mixtures thereof.
- 10. The composition of claim 1 wherein the B monomer is a methacrylic acid ester.
- 11. The composition of claim 10 wherein the B monomer is methacrylic acid esterified with an aliphatic alcohol of 1 to 22 carbon atoms.
- 12. The composition of claim 10 wherein the B monomer is selected from the group consisting of isobomylmethacrylate, methylmethacrylate, and mixtures thereof.
- 13. The composition of claim 1 wherein the oil comprises both a volatile solvent having a viscosity of 0.5 to 10 centistokes at 25.degree. C. and a nonvolatile oil having a viscosity of greater than 10 centistokes at 25.degree. C.
- 14. The composition of claim 13 wherein the volatile solvent comprises one or more compounds selected from the group consisting of cyclomethicones of up to 7 silicon atoms, linear dimethicone of up to 9 silicon atoms, and straight or branched chain paraffinic hydrocarbons having about 5 to 40 carbon atoms.
- 15. The composition of claim 1 wherein the nonvolatile oil comprises one or more compounds selected from the group consisting of silicones, fatty alcohols, fatty esters, and nonvolatile hydrocarbon oils.
- 16. The composition of claim 15 wherein the nonvolatile oil comprises one or more compounds selected from the group consisting of dimethicone and a fluoro guerbet ester.
- 17. The composition of claim 1 additionally comprising 1-70% of a wax having a melting point of 30 to 120.degree. C.
- 18. The composition of claim 17 wherein the wax is one or more compounds selected from the group consisting of an aliphatic hydrocarbon and a fluorinated silicone.
- 19. The composition of claim 1 which is an anhydrous stick.
