Abstract
Mineral sunscreen compositions having improved efficacy are described. The mineral sunscreen compositions include: (a) one or more mineral UV filtering agents; (b) one or more stilbenoids; (c) ethylhexylmethoxycrylene. (d) diethylhexyl syringylidenemalonate; and (e) a cosmetically acceptable carrier. The mineral sunscreen compositions provide a high sun protection factor (SPF) without requiring high amounts of mineral UV filtering agents. Also, the mineral sunscreen compositions are less opaque and white than traditional mineral sunscreen compositions making them aesthetically appealing to consumers.
