Novel Crystalline Polymorphs of Acetyl-Glycine-Beta-Alanine and Process of Making the Same

摘要

This invention discloses novel crystalline polymorphs of acetyl-glycine-beta-alanine and process of making the same. The mentioned crystalline polymorphs can exhibit excellent purity and storage stability according to this invention. Therefore, the mentioned crystalline polymorphs can be applied in topical cosmetic compositions, pharmaceutical compositions as skin care preparations, or other functional preparations.
