Page/Page column 5, (2009/01/20)
The invention relates to the use of 5,6-diphenyl-1,2,4-triazinic compounds of general formula (I), wherein cycle penetrating bonds display an ortho, meta or para indifferent substitution position, identical or different R1 and R2 represent a hydrogen, fluoride, chloride or bromine atom, C1 to C12 linear or branched alkyl, C1 A C18 linear or branched hydroxy, alkoxy poly(ethoxy)-alkoxy with a C1 to C4 alkyl fragment and an ethoxy number ranging from 1 to 4, amino or mono or di-alkylamino with a C1 to C4 alkyl fragment group, R3 represents a chlorine atom, a hydroxy, amino, a phenyl possibly 1 to 3 times substituted by a hydroxy radical situated at least in a para or phenyl position possibly 1 to 3 times substituted in an ortho, meta or para position by a C1 to C12 alkoxy or cyano or alkymino group with a C1 to C7 alkyl fragment in the form of active sun filters or light-protective agents and to cosmetic composition containing said compounds.
