The invention relates to the use of enaminotriazines of the formula I
1
in which the radicals Y, independently of one another, are hydrogen, an optionally substituted aliphatic, cycloaliphatic, araliphatic or aromatic radical having in each case up to 18 carbon atoms, the radicals X are identical or different, where at least one of the radicals X is the ethenyl radical of the formula II
2
and X may also have the meanings of Y, and where in the formula II the radicals R are identical or different and are cyano, optionally esterified carboxyl, substituted carbonyl, optionally substituted aminocarbonyl, optionally esterified sulfo, substituted sulfonyl or optionally esterified phosphono, and where two adjacent radicals R may optionally form a ring and the radicals R′ are identical or different and are hydrogen, an optionally substituted aliphatic, cycloaliphatic or aromatic radical having in each case up to
18
carbon atoms, as UV filters in cosmetic or pharmaceutical preparations for protecting human skin or human hair against solar rays, alone or together with compounds which absorb in the UV region and which are known per se for cosmetic preparations.
本发明涉及式 I 的烯氨三嗪的用途
1
其中自由基 Y 相互独立地为氢、任选取代的脂肪族、环脂族、芳脂族或芳香族自由基,在每种情况下最多具有 18 个碳原子,自由基 X 相同或不同,其中至少一个自由基 X 为式 II 的乙烯基
2
其中至少一个基 X 是式 II 2 的乙烯基,X 也可以具有 Y 的含义,在式 II 中,基 R 相同或不同,并且是氰基、任选酯化的羧基、取代的羰基、任选取代的氨基羰基、任选酯化的磺基、取代的磺酰基或任选酯化的膦酰基,相邻的两个基 R 可以任选形成一个环,并且基 R′相同或不同,并且是氢、任选取代的脂肪族基、环脂族基或芳香族基,在每种情况下最多具有 18 个碳原子。
18
在化妆品或药物制剂中用作紫外线过滤剂,以保护人体皮肤或头发免受太阳光的照射,可单独使用,也可与吸收紫外线的化合物一起使用,这些化合物本身已为化妆品制剂所熟知。
