S-TRIAZINIC DERIVATIVES HAVING BENZYLIDENE CAMPHRE SUBSTITUANTS, THEIR PREPARATION PROCESS, FILTRATING COSMETIC COMPOSITIONS CONTAINING THEM AND THEIR USE TO PROTECT THE SKIN AND HAIR AGAINST ULTRA-VIOLET RADITION

摘要

the invention relates to new derivatives of s - triaziniques responding to formula (i) wherein r1 is a group of formula (ii) and r2 is an alkoxy group, or a mono - or di alkylamino c8 - c20, or a group of formula (iii), in which n is equal to 0 or 1, r3 denotes an alkyl radical in a c4-c20, r4 denotes a hydrogen atom or a hydroxyl or alkoxy, c1 to c6.r5 denotes a hydrogen atom or a group coor3 where r3 is an alkyl radical, c4 to c20.the compounds of formula (i) can absorb ultraviolet radiation and have a good solubility in fats and oils.they are used in particular as sunscreens for the human skin and hair, as well as protective agents of the light in the plastics industry.
