Abstract
A sunscreen formulation includes (a) a volatile solvent; and (b) at least one film-forming polymer that is the reaction product of (i) at least one polyglycerol; (ii) at least one diacid having 4-30 carbon atoms; and (iii) at least one fatty acid having 8-30 carbon atoms. The sunscreen formulation is used in a method of protecting skin against damaging effects of the sun.
