Abstract

The present invention relates to a personal care composition containing a dispersed oil phase, a silicone elastomer and an aqueous phase. These compositions are rinsable and at the same time deposit oil and silicone elastomer onto all keratinous surfaces while providing improved skin feel. Additionally, the present invention relates to a method of using a rinse off personal care composition that contains an elastomer gel, a dispersion phase and an aqueous phase.

Claims

1. A personal care composition comprising,

a) a silicone elastomer gel;

b) a dispersed oil phase; and

c) an aqueous phase;

wherein said dispersed oil phase is present at a greater percentage by weight than said silicone elastomer;

wherein said silicone elastomer gel is entrapped within said dispersed oil phase.

2. The composition of claim 1, wherein said silicone elastomer comprises no more than about 40 weight percent of said composition.

3. The composition of claim 1, wherein said silicone elastomer comprises at least 1 weight percent of said composition.

4. The composition of claim 1, wherein the dispersed oil phase has a shear index of less than 0.9

5. The composition of claim 1 wherein the dispersed oil phase has a shear index of less than 0.6.

6. The composition of claim 1 wherein the dispersed oil phase comprises a skin compatible oil phase.

7. The composition of claim 6, wherein the ratio of said silicone elastomer to said skin compatible oil phase is from about 1:

100 to about 1;

1.

8. The composition of claim 1, wherein said silicone elastomer gel has a solvent phase, said solvent phase having an absolute difference of at least 1.2 Vaughn Solubility Parameter units.

9. The composition of claim 1, wherein said dispersed oil phase comprises no more than about 80 weight percent of said composition.

10. The composition of claim 1, wherein said dispersed oil phase is selected from the group consisting of petrolatum, mineral oil, silicone, triglycerides, esters and mixtures thereof.

11. The composition of claim 1, wherein said aqueous phase is water.

12. The composition of claim 1, which additionally comprises a surfactant.

13. The composition of claim 12, wherein the composition comprises no more than about 5 weight percent of said surfactant.

14. The composition of claim 12, which additionally comprises a polymer.

15. The composition of claim 12, wherein the surfactant is present in a gel-network.

16. The composition of claim 1, wherein the composition comprises at least 5 weight percent of a surfactant.

17. The composition of claim 16, wherein said composition comprises at least one anionic surfactant.

18. The composition of claim 1, further comprising one or more benefit agents selected from the group consisting of vitamins, sunscreens, thickening agents, preservatives, anti-acne medicaments, antioxidants, skin soothing and healing agents, chelators and sequestrants, fragrances, essential oils, skin sensates, pigments, pearlescent agents, lakes, colorings, anti-bacterial agents and mixtures thereof.

19. A method of using a personal care composition comprising:

a) applying to a substrate a personal care composition comprising;

i. a silicone elastomer gel;

ii. a dispersed oil phase; and

iii. an aqueous phase;

 

wherein said dispersed oil phase is present at a greater percentage by weight than said silicone elastomer; and

b) rinsing off said personal care composition.

20. The method of claim 19 wherein said silicone elastomer gel is entrapped within said dispersed oil phase.
