Abstract:
A cosmetic preparation comprising light protection agents, for protecting the human epidermis or human hair from UV light in the range from 280 to 400 nm, which comprises, in a cosmetically suitable carrier, alone or together with compounds which absorb in the UV region and are known per se for cosmetic and pharmaceutical preparations, compounds of the formula I in whichX is the divalent radical of oxygen, a carbonyl radical, optionally aliphatically substituted imino or the radical &boxH;CR9R10, Y is a carbonyl group or the radical &boxH;CR9R10, R1 and R2 are identical or different electron-withdrawing radicals, chosen from the group consisting of cyano, alkyl- or arylcarbonyl,-alkyloxy- or aryloxycarbonyl, optionally substituted aminocarbonyl, alkyl- or arylsulfinyl, alkyl- or arylsulfonyl and optionally substituted aminosulfonyl, R3 is a hydrogen atom, a cyano, hydroxyl, carboxyl or aminocarbonyl group or a C5-C20-aryl radical or C1-C20-alkyl radical optionally bonded via an oxygen bridge, an aminocarbonyl bridge or oxycarbonyl bridge, R4 is a hydrogen atom, a hydroxyl group, an amino group, or a C5-C20-aryl radical or C1-C20-alkyl radical optionally bonded via an oxygen bridge, and R5 to R10 independently of one another are hydrogen or C1-C20-alkyl radicals and where in addition R7 and R8 together with the chain carbon atom are a carbonyl group.
