Abstract

Cosmetic compositions which include low molecular weight non-volatile oils, such as dimethicone, along with silica and a volatile solvent are provided. Such compositions exhibit surprisingly beneficial properties such as long wear, resistance to color transfer, low tack and excellent comfort and shine.

Claims

1. A lip product composition comprising silica, a volatile solvent and a non-volatile oil having a molecular weight of about 60,000 Daltons or less.

2. The composition of claim 1, wherein the non-volatile oil is selected from the group consisting of dimethicone, dimethicone copolyol, and mixtures thereof.

3. The composition of claim 1, wherein the non-volatile oil has a molecular weight at a range between about 10,000 to about 60,000 Daltons.

4. The composition of claim 1, wherein the volatile solvent has as viscosity of 0.5 to 100 centipoise at 25°

C.

5. The composition of claim 1, wherein the non-volatile oil comprises dimethicone.

6. The composition of claim 1, further comprising a cosmetically acceptable carrier.

7. The composition of claim 6, wherein the acceptable carrier comprises a film former, a wax, an emulsifier, a pigment, a preservative, an essential oil, a natural oil, an antioxidant, a thickener, a sunscreen, and mixtures thereof.

8. The composition of claim 1, wherein the cosmetic composition is a lip product.

9. A cosmetic composition comprising:

a) from about 0.1-60% by weight of trimethylated silica,

b) from about 0.1-60% by weight of a volatile solvent having a viscosity of 0.5 to 100 centipoise at 25°

C., and

c) 0.1-60% of a non-volatile, silicone oil selected from the group consisting of dimethicone, dimethicone copolyol, and mixtures thereof, having a molecular weight of about 60,000 Daltons or less.

10. The composition of claim 9, wherein the non-volatile, silicone oil comprises dimethicone.

11. The composition of claim 9, wherein the non-volatile, silicone oil has a molecular weight at a range between about 10,000 to about 60,000 Daltons.

12. The composition of claim 9, further comprising a cosmetically acceptable carrier, wherein said carrier comprises from about 0.1-80% of the composition by weight.

13. The composition of claim 11, wherein the cosmetic composition is lip product.

14. A cosmetic composition comprising a volatile solvent and a non-volatile silicone oil having a molecular weight of about 60,000 Daltons or less, wherein said cosmetic composition exhibits less tack and greater shine than a comparable composition comprising a non-volatile oil having a molecular weight substantially higher than 60,000 Daltons.

15. The cosmetic composition of claim 14 comprising:

a) from about 0.1-60% by weight of trimethylated silica,

b) from about 0.1-60% by weight of a volatile solvent having a viscosity of 0.5 to 100 centipoise at 25°

C., and

c) 0.1-60% of a non-volatile, non-fluorinated silicone oil selected from the group consisting of dimethicone, dimethicone copolyol, and mixtures thereof, having a molecular weight about 60,000 Daltons or less.

16. The composition of claim 15, wherein the non-volatile, non-fluorinated silicone oil comprises dimethicone.

17. The composition of claim 15, wherein the non-volatile, non-fluorinated silicone oil has a molecular weight at a range between about 10,000 to about 60,000 Daltons.

18. The composition of claim 15, further comprising a cosmetically acceptable carrier, wherein said carrier comprises from about 0.1-80% of the composition by weight.

19. The composition of claim 18, wherein the cosmetic composition is lip product.

20. The composition of claim 19, further comprising at least one pigment.
