Abstract
The present invention is directed toward a series of polyesters synthesized utilizing propane diol with tunable ascetics and performance in cosmetic formulation. These novel propane diol polyesters are designed to have great esthetics in cosmetic formulation. The physical properties and aesthetics of the current invention can be tuned rapidly by controlling the fatty groups, as well as the molecular weight of the polymer. The resulting propane diol polyesters have outstanding aesthetics and physical properties.
