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.
Claims23
A rinsable personal care composition comprising:
- a) 0.1 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 comprising:
- i. an average particle size not greater than about 80 μm;
- ii. an aspect ratio defined by A/B=or >0.20, wherein said length of said hydrophobically modified non-platelet particle being A and said width of said hydrophobically modified non-platelet particle being B;
- iii. a hydrophobic coating comprising no more than 20 weight percent of said hydrophobically modified non-platelet particle, wherein said hydrophobic coating comprises a material selected from the group consisting of silicone, acrylate silicone copolymers, alkyl silane, dimethicone, triethoxycaprysilane, dimethylpolysiloxane, and mixtures thereof;
- and
- d) 10 to 99 weight percent of water;
- wherein said composition comprises a ratio of said hydrophobically modified non-platelet particle to said skin benefit agent or emollient of about 1:7 to about 1:60.
