PHOTOSTABLE SUNSCREEN COMPOSITIONS CONTAINING POLYESTERS OF NAPHTHALENE DICARBOXYLIC ACID |
摘要 |
A sunscreen composition containing a UV-A dibenzoylmethane derivative, such as 4-(1,1-dimethylethyl)-4'-methoxydibenzoylmethane (PARSOL3 1789), and a stabilizer for the dibenzoylmethane derivative having structure (I) wherein each R', same or different, is an alkyl group, straight or branched chain, having 1 to 22 carbon atoms. These diesters of structure (I) are quite effective in stabilizing the dibenzoylmethane derivative UV-A filter compounds making them more effective, and effective for longer periods of time.
