Abstract
The present disclosure generally relates to a waterproofing polymer that is a substantially non-sequential reaction product of the following components: (i) at least one polyglycerol; (ii) at least one dimer acid; and (iii) at least one fatty acid having 8-30 carbon atoms, wherein (iii) and (i) are in a molar ratio of less than 2:1. The components are charged to a reaction vessel and subsequently reacted to produce a polyester polymer having excellent waterproofing properties. The polymers impart high static and water-resistant SPF to anhydrous sunscreen formulations.
