Use of an amino-substituted 2-hydroxybenzophenone in the preparation of cosmetic or dermatological compositions (for the protection of skin and/or hair against UV radiation) comprising one or more silicated derivative with a benzotriazole functional group and dibenzoylmethane derivative to produce a synergic effect on the sun protection factor UVAPPD. <??>An amino-substituted 2-hydroxybenzophenone of formula (III) is used in the preparation of cosmetic or dermatological compositions (for the protection of the skin and/or the hair against UV radiation) comprising one or more silicated derivative with a benzotriazole functional group and dibenzoylmethane derivative to produce a synergic effect on the sun protection factor UVAPPD. <??>R<1>, R<2> = H, 1-20C alkyl, 2-10C alkenyl, 3-10C cycloalk(en)yl or, together with the nitrogen to which they are attached, form a 5 or 6 link ring; <??>R<3>, R<4> = 1-20C alkyl, 2-10C alkenyl, 3-10C cycloalk(en)yl, 1-12C alkoxy, (1-20C)alkoxycarbonyl, 1-12C (di)alkylamino, optionally substituted aryl or heteroaryl, or a hydrosolubilizing substituent (carboxylate or sulfonate or ammonium residue); <??>X' = H, COOR<5>, CONR<6>R<7>; <??>R<5>, R<6>, R<7> = H, 1- 20C alkyl, 2-10C alkenyl, 3-10C cycloalkyl or cycloalk(en)yl, -(Y'O)o-Z' or aryl; <??>Y' = - (CH2)2-, -(CH2)3-, -(CH2)4- or -CH(CH3)-CH2-; <??>Z' = -CH2CH3, -CH2CH2CH3, -CH2CH2CH2CH3 or -CH(CH3)CH3; <??>m', n' = 0-3; <??>o = 1- 2.
