摘要：
The present invention includes a urea powder, the particles of which are protected in a dimethicone and silica mixture, prior to being incorporated into anhydrous compositions. The protected urea is capable of imparting a cooling activity to a topical composition. The invention also pertains to topical, cooling compositions containing a protected urea. The use of the protected urea to impart a cooling activity to topical anhydrous compositions is new. Topical, anhydrous compositions comprising the protected urea are also new. Anhydrous compositions containing the protected urea are stable against hydrolysis that might otherwise occur due to the ambient humidity. Disclosed compositions create a clean and fresh feel for a user.
