Fine dry particulate retinoid active agent compositions and topical formulations including the same

Abstract

Fine dry particulate retinoid compositions suitable for use in topical formulations, as well as methods of making the same, are provided. In the dry particulate retinoid compositions, the retinoid active agent is associated with the particles, e.g., via entrapment in the pores of the particles and/or ionic binding and/or non-covalent binding to the surface of the particles and/or loosely associated with the particles. Also provided are topical formulations which include the dry particulate retinoid compositions of the invention, and methods of using the same.

Dependencies are inferred from the claim text.
