Abstract

A rinsable personal care composition includes (a) 0 to 75 weight percent of a composition surfactant; (b) 0.01 to 99 weight percent of a skin benefit agent or emollient; (c) 0.01 to 20 weight percent of a hydrophobically modified non-platelet particle; and (d) 0 to 99% water.

Claims

1. A rinsable personal care composition comprising:

a) 0 to 75 weight percent of a composition surfactant;

b) 0.01 to 99 weight percent of a skin benefit agent or emollient

c) 0.01 to 20 weight percent of a hydrophobically modified non-platelet particle; and

d) 0 to 99% water.

2. The composition of claim 1, comprising at least 0.1 weight percent of said hydrophobically modified non-platelet particle.

3. The composition of claim 1, comprising no more than about 1 weight percent of said hydrophobically non-platelet particle.

4. The composition of claim 1, comprising no more than about 5 weight percent of said hydrophobically non-platelet particle.

5. The composition of claim 1, comprising no more than 80 weight percent of said skin benefit agent or emollient.

6. The composition of claim 1, comprising at least 1 weight percent of said skin benefit agent or emollient.

7. The composition of claim 1, wherein the ratio of said hydrophobically modified non-platelet particle to said skin benefit agent or emollient is about 1:

1 to about 1;

100.

8. The composition of claim 1, wherein said skin benefit agent or emollient is selected from the group consisting of petrolatum, mineral oil, silicone, triglycerides, esters and mixtures thereof.

9. The composition of claim 1, further comprising a said continuous aqueous phase.

10. The composition of claim 1, wherein said hydrophobically modified non platelet particle is entrapped within said skin benefit agent or emollient.

11. The composition of claim 1, wherein the composition comprises no more than about 5 weight percent of said surfactant.

12. The composition of claim 11, further comprising a polymer.

13. The composition of claim 11, wherein said surfactant is present in a gel-network.

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

15. The composition of claim 14, wherein said composition comprises at least one anionic surfactant.

16. The composition of claim 14, further comprising a polymer.

17. The composition of claim 1, comprising one or more benefit agents selected from the group consisting of skin moisturizing agents, humectants, 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 and mixtures thereof.

18. The composition of claim 1, further comprising a structurant.

19. The composition of claim 1, further comprising a hydrophobically modified interference pigment.

20. The composition of claim 1, further comprising a non modified particle.
