Abstract

The invention provides unique cosmetic compositions containing at least two different pigment types and a carrier, the pigments of different types being physically separated from each other in individual capsules within the carrier. Compositions of the invention provide vibrant color to the skin, but without the ashiness typical of compositions containing traditional pigment grinds.

Claims

1. A color cosmetic composition containing at least two different pigment types and a carrier, the pigments of different types being physically separated from each other in individual capsules within the carrier.

2. The composition of claim 1 in which the capsule comprises a chemical shell encompassing the pigment.

3. The composition of claim 2 in which the capsule is a colored glass bead.

4. The composition of claim 2 in which the capsule is comprises a silica shell.

5. The composition of claim 2 in which the capsule is surface-treated.

6. The composition of claim 2 which is an anhydrous composition.

7. The composition of claim 6 which is a powder composition.

8. The composition of claim 6 in which the capsule comprises a silica shell.

9. The composition of claim 1 which is a water and oil emulsion.

10. The composition of claim 9 in which the capsule is a micelle.

11. A color cosmetic emulsion composition containing at least two different pigments and at least two dispersed micellar phases, in which each different pigment is contained within micelles in a different dispersed phase within the carrier.

12. The composition of claim 11 in which the micelles have an average size of from about 1 to about 400μ

.

13. The composition of claim 12, in which the micelles have an average size of less than about 100μ

.

14. The composition of claim 12 in which the micelles have an average size of about 1 to about 60μ

.

15. The composition of claim 12 in which the micelles have an average size of about 5 to about 20μ

.

16. The composition of claim 12 in which the pigment is in an oil phase micelle, and is hydrophobically surface-treated.

17. The composition of claim 12 in which the pigment is in a water phase micelle and is hydrophilically surface-treated.

18. A method of making a color cosmetic composition containing at least two different pigments and a carrier, the method comprising the steps of (a) preparing one extender for each different pigment, and (b) blending each extender into the carrier without grinding the pigments together, whereby a composition is obtained in which there is substantially no physical contact in the carrier between the different types of pigments.

19. The method of claim 18 in which the composition is anhydrous and blending occurs at a speed of about 500 to about 800 rpm.

20. The method of claim 18 in which the composition is a water and oil emulsion and the blending occurs at a speed of about 500 to about 1200 rpm.

21. A composition obtained according to the method of claim 18.

22. A composition obtained according to the method of claim 19.

23. The composition of claim 22 which is a powder composition.

24. A composition obtained according to the method of claim 20.

25. A method of making a color cosmetic composition which comprises blending into a carrier at least two different pigments that are individually encapsulated in a chemical shell, and dispersing the pigments throughout the carrier.
