Abstract

Compositions suitable for use as cosmetic products (e.g., skin cream) are disclosed. Methods of making and using compositions suitable for use as cosmetic products are also disclosed.

Claims

1. A composition comprising:

particulate material having a Total Available Fluid Absorption Capacity of Particulate (TAFACP) value of greater than zero; and

a fluid phase comprising;

a non-volatile component; and

a volatile component;

wherein said composition has a weight ratio, R, of total non-volatile content (IVC) to TAFACP, and R ranges from greater than 0 to less than about 8.0.

2. The composition of claim 1, wherein said particulate material has an average particle size ranging from about 0.1 to about 35 microns.

3. The composition of claim 1, wherein said fluid phase comprises two or more distinct phases.

4. The composition of claim 1, wherein said fluid phase comprises from about 1.0 to about 60.0 wt % of said non-volatile component, and from about 99.0 to about 40.0 wt % of said volatile component, based on a total weight of said fluid phase.

5. The composition of claim 1, wherein said fluid phase comprises from about 1.0 to about 40.0 wt % of said non-volatile component, and from about 99.0 to about 60.0 wt % of said volatile component, based on a total weight of said fluid phase.

6. The composition of claim 1, wherein R ranges from about 0.5 to about 7.4.

7. The composition of claim 6, wherein R ranges from about 2.0 to about 6.0.

8. The composition of claim 6, wherein said composition further comprises one or more additional components selected from deionized water, humectant, emollient, fragrance, soluble polymer, or any combination thereof.

9. The composition of claim 8, wherein said composition comprises from about 1.0 to about 50.0 wt % of said particulate material, and from about 99.0 to about 50.0 wt % of said fluid phase, based on a total weight of said composition.

10. A film comprising the composition of claim 1.

11. The film of claim 10, wherein said film comprises a substantially transparent continuous film having an outermost rough surface.

12. The film of claim 11, wherein said outermost rough surface has a surface roughness of at least about the wavelength of light.

13. The film of claim 11, wherein said outermost rough surface has one or more lower surface points along said outermost rough surface and one or more upper surface points along said outermost rough surface, said one or more lower surface points being separated from said one or more upper surface points in a z direction by a distance of from about 0.05 to about 20.0 μ

m.

14. A multi-layer article comprising:

skin having an outer skin surface; and

the composition of claim 1 on said outer skin surface,

19. (canceled)

20. (canceled)

21. A method of hiding skin imperfections, said method comprising:

applying a composition onto an outer skin surface, the composition comprising;

particulate material having a Total Available Fluid Absorption Capacity of Particulate (TAFACP) value of greater than zero; and

a fluid phase comprising;

a non-volatile component; and

a volatile component;

wherein the composition (i) has a weight ratio, R, of total non-volatile content (NVC) to TAFACP with R ranging from greater than 0 to less than about 8.0.

22. The method of claim 21, wherein said fluid phase comprises from about 1.0 to about 60.0 wt % of said non-volatile component, and from about 99.0 to about 40.0 wt % of said volatile component, based on a total weight of said fluid phase.

23. The method of claim 21, wherein said fluid phase comprises from about 1.0 to about 40.0 wt % of said non-volatile component, and from about 99.0 to about 60.0 wt % of said volatile component, based on a total weight of said fluid phase.

24. The method of claim 21, wherein R ranges from about 0.5 to about 7.4.

25. The method of claim 21, wherein A ranges from about 2.0 to about 6.0.
