Cosmetic or dermatologic compositions containing microspheres

Abstract

The invention relates to cosmetic or dermatologic compositions comprising a microsphere and a film forming component.

Description

Claims

1. A composition comprising a cosmetically acceptable medium, an adhesive microsphere, and a film forming component.

2. The composition of claim 1, wherein the film forming component comprises at least two film forming agents.

3. The composition of claim 2, wherein the Tgs of the at least two film forming agents are separated by at least about 20° C.

4. The composition of claim 2, wherein the Tgs of the at least two film forming agents are separated by at least about 60° C.

5. The composition of claim 2, wherein the Tg of one of the two film forming agents is above 25° C. and the Tg of the other of the two film forming agents is below 25° C.

6. The composition of claim 1, wherein the composition comprises from about 0.3% to about 50% of the film forming component on a dry weight basis with respect to the total weight of the composition.

7. The composition of claim 1, wherein the composition comprises from about 2% to about 30% of the film forming component on a dry weight basis with respect to the total weight of the composition.

8. The composition of claim 2, wherein the ratio of the first film forming agent to the second film forming agent is 1:10 to 20:1.

9. The composition of claim 1, wherein the adhesive microsphere is prepared by polymerization of monomer(s) selected from the group consisting of acrylates, methacrylates, acrylic acid, methacrylic acid, acrylamides, acrylonitriles, pyrrolidones, vinyl esters, and mixtures thereof.

10. The composition of claim 1, wherein the adhesive microsphere is prepared by polymerization of monomer(s) selected from the group consisting of acrylates, methacrylates, acrylic acid, methacrylic acid, and mixtures thereof.

11. The composition of claim 1, wherein the adhesive microsphere is prepared by polymerization of ethylhexylacrylate.

12. The composition of claim 2, wherein at least one of the film forming agents is a polymer prepared by polymerization of monomer(s) selected from the group consiting of acrylates, methacrylates, acrylic acid, methacrylic acid, and mixtures thereof.

13. The composition of claim 2, wherein both of the film forming agents are polymers prepared by polymerization of monomer(s) selected from the group consiting of acrylates, methacrylates, acrylic acid, methacrylic acid, and mixtures thereof.

14. The composition of claim 1, wherein the composition further comprises at least one sunscreen agent, at least one pigment, or mixtures thereof.

15. The composition of claim 1, wherein the composition is essentially free of non-adhesive particles.

16. The composition of claim 1, wherein the adhesive microsphere has a mean length of about 30 to about 1000 microns.

17. The composition of claim 1, wherein the adhesive microsphere has a mean length of about 30 to about 100 microns

18. A method for styling a keratin material comprising applying to the keratin material a keratin material styling effective amount of a composition comprising a cosmetically acceptable medium, an adhesive microsphere, and a film forming component.

19. The method of claim 18, wherein the keratin material is hair.

20. The method of claim 18, wherein the keratin material is an eyelash.

21. A method for holding the shape or curl of a keratin material comprising applying to the keratin material a shape or curl holding effective amount of a composition comprising a cosmetically acceptable medium, an adhesive microsphere and a film forming component.

22. The method of claim 21, wherein the keratin material is hair.

23. The method of claim 21, wherein the keratin material is an eyelash.
