Skin care composition comprising turbostratic boron nitride

1. A personal care composition comprising:

a) turbostratic boron nitride;

b) porous silica having a specific surface area of higher than 300 m 2 /g; and

c) a cosmetically acceptable carrier;

wherein oxygen content is from 1 to 3% by mole of the turbostratic boron.

2. The composition as claimed in claim 1 wherein the turbostratic boron nitride has an average diameter from 100 nm to 100 microns.

3. The composition as claimed in claim 1 wherein the turbostratic boron nitride is present in amount of 0.01 to 15% by weight of the composition.

4. The composition as claimed in claim 1 wherein the porous silica is a microsphere having an oil absorption value of higher than 100 g/100 g.

5. The composition as claimed in claim 1 wherein the porous silica has an average diameter of from 200 nm to 40 microns.

6. The composition as claimed in claim 1 wherein the porous silica is present in amount from 0.01 to 20%.

7. The composition as claimed in claim 1 further comprising 1 to 15% silicone elastomer by weight of the composition.

8. The composition as claimed in claim 7 wherein the silicone elastomer is a vinyl dimethicone/dimethicone crosspolymer.

9. The composition as claimed in claim 1 further comprising a whitening pigment having a refractive index higher than 1.8.

10. The composition as claimed in claim 9 wherein the whitening pigment is selected from titanium dioxide, zinc oxide, or a mixture thereof.

11. The composition as claimed in claim 9 wherein the whitening pigment is present from 0.1 to 10% by weight of the composition.

12. The composition as claimed in claim 1 wherein the carrier is an oil-in-water emulsion.

13. The composition as claimed in claim 1 further; comprising an organic sunscreen.

14. The composition of claim 1 wherein the composition reduces the appearance of fine lines, wrinkles, pores and/or blemish spots; evens skin tone, or a combination thereof on a skin surface and the turbostratic boron nitride has an average particle diameter from 1 to 15 microns and makes up from 0.4 to 8% by weight of the composition; the porous silica has a absorption value of higher than 280 g/100 g and an average diameter from 1 to 20 microns and is present in an amount from 0.2 to 9%.

15. A method of reducing an appearance of fine lines, wrinkles, pores and/or blemish spots; evening skin tone, or a combination thereof on skin comprising the step of applying a composition as claimed in claim 1 topically to a skin surface.
