    • The invention relates to complexes of specific flavonoid derivatives of formula (I), wherein R 1 and R 2 are selected among H and OR 11 , OR 11 independently representing OH, straight-chain or branched C 1 to C 20 alkyloxy groups, straight-chain or branched C 3 to C 20 alkenyloxy groups, straight-chain or branched C 1 to C 20 hydroxyalkoxy groups, the hydroxy group(s) being optionally bonded to primary or secondary carbon atoms of the chain and the alkyl chain being optionally interrupted by oxygen, and/or C 3 to C 10 cycloalkyloxy groups and/or C 3 to C 12 cycloalkenyloxy groups, the rings being optionally bridged by -(CH2) n groups, wherein n = 1 to 3, and/or monoglycosyl radicals and/or oligoglycosyl radicals, provided that at least one of the radicals R 1 and R 2 represents OR 11 , while R 3 to R 10 can be identical or different and independently represent radicals that are largely inert regarding UV properties. Also disclosed are preparations containing such complexes, corresponding methods for producing the inventive complexes and the preparations containing the same, as well as the use thereof, especially for nourishing, preserving, and improving the overall condition of skin or hair and providing protection from light.
    • 本发明涉及式(I)式的某些类黄酮衍生物,其中R 1 和R 2 选自H和OR 11 的复合物 其中或 11 独立地是OH,直链或支链的C 1 - Visual C 20 - 烷氧基,直链或支链的C 3 - Visual C 20 链烯氧基,直链或支链的C 1 - Visual C 20 -hydroxyalkoxy基团,其中羟基基团(一个或多个 )可以被结合到所述链的一个伯或仲碳原子,此外所述烷基链还可被氧间断,和/或C 3 - Visual C 10 环烷氧基和/ 或C 3 - Visual C 12 -Cycloalkenyloxygruppen,其中该环可以各自还为 - (CH 2)名词基团,其中n = 1至3 可以是桥连和/或单 - 和/或oligoglycosyl基,条件是R的至少一个 1 和 [R 2 表示OR 11 和R 3 至R 10 可以是彼此独立地相同或不同,并且, 相对于所述UV性质很大程度上惰性的基团,含有用于制备复杂的相应过程或此类复合物含有它们和它们的用途的制剂,特别是用于皮肤或毛发和的一般状态的关心,保存或改进的准备表示 光保护。
