More Information
Summary:The present invention relates to compositions suitable for providing protection against the harmful effects of ultraviolet radiation. The compositions provide excellent efficiency, broad spectrum UV efficacy, and photostability. Methods of use for these compositions are also disclosed. The compositions comprise: a) an effective amount of a UVA-absorbing dibenzoylmethane sunscreen active; b) an effective amount of a tertiary amine containing 2 or less nitrogen atoms having the formula wherein R1, R2, and R3 are independently selected from the group consisting of straight, branched or cyclic C1-C30 alkyls and aryls other than those aryls substituted in the para position with a benzofuran, carboxylic acid, or ester group; wherein R1, R2, and R3, can together form with each other a ring having at least 2 carbon atoms; and wherein when either R1, R2, or R3 contains a hydrogen alpha to the nitrogen atom, it does not contain a beta hydrogen; and c) a suitable carrier.
