UV Compositions Having Low Active Concentrations and High In Vivo SPF |
| 摘要 |
A UV composition that contains from about 0.2% to about 2% of a UV stabilizer which is an alpha-cyanodiphenylacrylate of the general formula:;;At least one of R1 or R2 is a C1-C8 alkyoxy radical, and one of R1 or R2 is a straight or branched chain C1-C30 alkoxy radical or any non-alkoxy radical, or hydrogen; and R3 is a straight or branched chain C1-C30 alkyl. Further, the UV composition comprises from about 1.5% to about 3.5% of a UV active which is a butyl methoxydibenzoylmethane, and from about 3% to about 9% of a UV active that is 2-Ethylhexyl-3-(4-methoxyphenyl)prop-2-enoate. A dermatologically acceptable carrier is also provided. Preferably, the weight ratio of alpha-cyanodiphenylacrylate to butyl methoxydibenzoylmethane is from about 1:2 to about 1:5. |
