Abstract: Disclosed are non-adhesive antiperspirant compositions comprising a water or sweat-reactive monomer as the antiperspirant active, an anhydrous carrier, and an optional polymerization inhibitor, wherein the compositions are applied topically to the underarm or other suitable area of the skin to inhibit or prevent perspiration. The applied compositions form a discontinuous polymer-containing antiperspirant active on the applied skin surface, wherein the polymer-containing active is derived from water-reactive monomers that reacts with sweat at the opening of the sweat ducts after application, to thereby polymerize and form the polymer-containing antiperspirant active over and within the affected sweat ducts. The antiperspirant compositions and corresponding methods of application provide alternative antiperspirant active materials and product formulations, and provide improved efficacy and/or application cosmetics.

Abstract: The present invention are for emulsion compositions and the process for making such compositions containing biological and cosmetic actives subject to hydrolysis of actives during processing and storage of the emulsion composition. Buffers are incorporated into emulsion at a point wherein the acidic and basic conditions created during processing have little effect on compositions.
