    • The present application relates to a UV protecting composition containing: (a) at least one organic UV sunscreen active; (b) at least one semi-crystalline polymer which is solid at ambient temperature and has a melting point of less than about 8O0 C; (c) hollow latex particles; and (d) at least one additional ingredient chosen from: i) a UV light absorbing compound having an SPF of less than 2, and ii) an SPF booster capable of reflecting UV light, different from hollow latex particles, wherein the hollow latex particles are employed in an amount equal to, or greater than, the amount of the at least one organic UV sunscreen active present in the composition. The invention also relates processes for protecting cellular targets from UV rays and free radical-induced damage by topically applying a UV protecting composition onto a keratinous substance, such as skin, and processes for making such compositions.
    • 本申请涉及一种UV保护组合物,其含有:(a)至少一种有机UV防晒活性物质; (b)至少一种在环境温度下为固体且熔点小于约80℃的半结晶聚合物; (c)中空胶乳颗粒; 和(d)选自以下的至少一种附加成分:i)SPF小于2的UV光吸收化合物,和ii)能够反射与中空胶乳颗粒不同的UV光的SPF增效剂,其中所述中空胶乳颗粒 以等于或大于组合物中存在的至少一种有机UV防晒活性物的量使用。 本发明还涉及通过将角质化物质(例如皮肤)局部施用UV保护组合物以及制备这种组合物的方法来保护细胞靶免受紫外线和自由基诱导的损伤的方法。
