    摘要: A sunscreen composition in the form of a water-in-oil emulsion comprising: a) a water phase of about 20% to 60% by weight relative to the total weight of the sunscreen composition; b) one or more mineral UV filtering agents; c) one or more oil thickening agents selected from poly C10-30 alkyl acrylate, hydrogenated jojoba oil and its derivatives and mixtures thereof; wherein the total amount of oil thickening agents is about 0.5% to about 4% by weight relative to the total weight of the sunscreen composition; wherein when hydrogenated jojoba oil is present, the amount of hydrogenated jojoba oil is no more than 1.5 times the amount of poly C10-30 alkyl acrylate; wherein the composition has a viscosity of about 0.1 Pa·s to about 5 Pa·s at 25° C. at 10 rad/s; and wherein the inflection point of the largest viscosity transition at 10 rad/s is between 30° C. to 40° C.

    摘要: 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.
