Abstract
An anhydrous topical composition provides a water repellent surface. The anhydrous topical composition has at least one film former with surface tension lower than 35 dynes/cm, at least one particle having a hydrophobic surface or a hydrophobic surface treatment, and a volatile topical carrier.
Claims19
An anhydrous topical composition comprising:
- at least one film former having a surface tension lower than 35 dynes/cm selected from the group consisting of glycol ester crosspolymers, silicones, resins and derivatives thereof, and olefinic polymers and crosspolymers, said at least one film former is present in an amount of 5% to 10% by weight based on a total weight of said anhydrous topical composition;
- particles comprising hydrophobic-treated silica, fumed silica, polytetrafluoroethylene, polyurethane, silica silylate, polymethylsilsesquioxane, hydrophobic-treated calcium silicate, hydrophobic-treated cellulose, hydrophobic-treated polymethylmethacrylate, hydrophobic-treated zinc oxide, hydrophobic-treated titanium dioxide, or combinations thereof, said particles present in an amount of 1.5% to 10% by weight based on the total weight of said anhydrous topical composition;
- a volatile topical carrier present in an amount of 30% to 60% by weight based on the total weight of said anhydrous topical composition;
- and
- an active agent selected from the group consisting of a sunscreen active agent, an insect repellent, a colorant, and combinations thereof;
- wherein said anhydrous topical composition has an initial water contact angle greater than 90 degrees.

- and
- a volatile topical carrier;
- wherein said anhydrous sunscreen composition has an initial water contact angle greater than 90 degrees and a water contact angle of at least 60 degrees after 40 minutes.
3 more elements
