| abstract |
The invention relates to the use of copolymers in cosmetics or dermatological sun protection agents with a sun protection factor (SPF) of at least 4. Said polymers are obtained by the copolymerisation of at least one ethylenically unsaturated dicarboxylic acid anhydride, derived from at least one dicarboxylic acid, with between 4 and 8 C atoms and at least one oligomer of branched or unbranched C<SUB>3</SUB>-C<SUB>10</SUB> alkene, at least one oligomer having an average molecular weight M<SUB>n</SUB> ranging between 300 and 5000 g/mol, preferably up to 1200 g/mol, or are obtained by the oligomerisation of at least 3 equivalents of C<SUB>3</SUB>-C<SUB>10</SUB> alkene. |
