COMPOUNDS CONTAINING A MICHAEL-ACCEPTOR, ESPECIALLY MALEIMIDE OR MALEIC ACID DERIVATIVES, DIRECTLY OR INDIRECTLY LINKED TO A CHROMOPHOREAND THEIR USE IN LONG LASTING SUNSCREEN COMPOSITIONS |
摘要 |
The present invention relates to compounds which are useful as sunscreens. The compounds persists on the skin for much longer than conventional sunscreens because they comprise a Michael acceptor linked directly or indirectly to a chromophore. The Michael acceptor is capable of undergoing a conjugate addition reaction with thiol groups present in cysteine residues of keratin and thus the compound is chemically bound to the skin and will not be removed by immersion in water.
