Abstract:
A sunscreen composition containing: (a) a polyacrylate booster comprising at least one acrylates copolymer having a weight average molecular weight ranging from about 75,000 to 140,000 g/mol and a Tg ranging from −20 to 50 C; and (b) a UV filter system containing a combination of UV filters comprised of: octocrylene, avobenzone, octisalate, and homosalate, and optionally oxybenzone; wherein the ratio of each filter relative to avobenzone is as follows: the ratio of octocrylene to avobenzone is 1.6:1.0 to 2.4:1.0, the ratio of oxybenzone to avobenzone 0.0:1.0 to 0.016:1.0, the ratio of octisalate to avobenzone is 1.3:1.0 to 2.0:1.0, and the ratio of homosalate to avobenzone is 2.3:1.0 to 3.6:1
