Polyesters as topical delivery systems
Article Abstract:
Molecular weight and crosslinking are the structural features of polyesters that had the most effect on retention of sunscreen agents in the outer stratum corneum. Polyesters with greater molecular weight and a higher degree of crosslinking tended to concentrate the active ingredients in the most narrow band and in the nearest surface of the skin. Both termination and backbone had insignificant effect on a polyester's ability to keep the sunscreen agents within the outer stratum corneum. Termination and backbone, however, have significant effects on the co-solubility of polyesters with both active ingredients and excipients.
