Abstract: Sunscreen compositions, products and methods that include at least one sunscreen active agent and one or more water insoluble film forming polymers. The compositions, products and methods may further include one or more active or inactive cosmetic ingredients. The water insoluble film forming polymers synergistically affect the UVA and UVB sunscreen active agents, in particularly the UVA sunscreen active agents by significantly enhancing the water resistance of the UVA sunscreen active agents after water exposure as determined by the SPF and UVAPF values measured before and after water exposure.

Abstract: The present invention relates to highly stable water-in-oil sunscreen emulsions that provide a high sunscreen efficiency (“SE”) having a sun protection factor (“SPF”) of X, where X is at least about 15, and having a sunscreen efficiency (“SE”) of at least 2, preferably at least 3, where SE is the ratio of SPF over the total weight percentage of sunscreen actives based on the total weight of the composition. The emulsions of the present invention provide photoprotection for the period corresponding to the labeled SPF throughout the period of exposure to natural sunlight and comprises (i) at least one sunscreen active and (ii) an alkyl dimethicone copolyol emulsifier in which the water-soluble, alkyl-soluble and silicone-soluble groups of the dimethicone copolyol are in specific ratios to each other. Preferably, the high SE water-in-oil emulsion comprises both a UV-A sunscreen and UV-B sunscreen. More preferably, the combination of sunscreen actives is photostable.
