Abstract
The present invention is directed toward a series of polyesters with tunable ascetics and skin conditioning properties for use in cosmetic formulation, specifically sun screening formulations in which the performance is improved by a synergistic effect between the sunscreening actives and the polyester. These novel polyglycerol polyesters are designed to be multidimensional. The physical properties and aesthetics of the current invention can be tuned rapidly by controlling the ratio of fatty groups, as well as the cross-linker used. The resulting polyglycerol polyesters have outstanding aesthetics and physical properties.
