发明名称 Stable sunscreen composition containing dibenzoylmethane derivative, E. G., PARSOL 1789, and C12, C16, C18, branched chain hydroxybenzoate and/or C12, C16, branched chain benzoate stabilizers/solubilizers
摘要 A sunscreen composition containing a UV-B dibenzoylmethane derivative, such as 4-(1,1-dimethylethyl)-4'-methoxydibenzoylmethane (PARSOL 1789), and a stabilizer/solubilizer for the dibenzoylmethane derivative selected from formula (I) and formula (II), and mixtures thereof: <IMAGE> (I) wherein m=5, 7, 9 or mixtures and n=4, 6, 8 or mixtures; , 6 or mixtures. These long branched chain alkyl hydroxybenzoates and long branched chain benzoates having a C4+ branch at the 2 position are quite effective in stabilizing the dibenzoylmethane derivative UV-B filter compounds making them more effective; effective for longer periods of time.
