    • The invention relates to complexes of certain flavonoid derivatives, of the formula (I), where R1 and R2 are selected from H and OR11, where OR11 stands, independently of one another, for OH, straight-chain or branched C1- to C20-alkoxy groups, straight-chain or branched C3- to C20-alkenyloxy groups, straight-chain or branched C1- to C20-hydroxyalkoxy groups, where the hydroxyl group(s) may be bonded to a primary or secondary carbon atom in the chain and furthermore the alkyl chain may also be interrupted by oxygen, and/or C3- to C10-cycloalkoxy groups and/or C3- to C12-cycloalkenyloxy groups, where the rings may in each case also be bridged by —(CH2)n— groups, where n=1 to 3, and/or mono- and/or oligoglycosyl radicals, with the proviso that at least one radical from R1 and R2 stands for OR11, and R3 to R10 may be identical or different and stand, independently of one another, for radicals which are substantially inert with respect to the UV properties, to compositions which comprise such complexes, to corresponding processes for the preparation of the complexes or the compositions comprising the latter, and to the use thereof, in particular for the care, preservation or improvement of the general condition of the skin or hair and for light protection.
    • 本发明涉及式(I)的某些类黄酮衍生物的复合物,其中R1和R2选自H和OR11,其中OR11彼此独立地表示OH,直链或支链C1- 烷氧基,直链或支链C 3 -C 20链烯氧基,直链或支链C 1至C 20 - 羟基烷氧基,其中羟基可以键合到链中的伯或仲碳原子上, 此外,烷基链还可被氧,和/或C 3 -C 10环烷氧基和/或C 3至C 12 - 环烯基氧基间隔,其中每种情况下的环也可以被 - (CH 2)n - 基团桥连 ,其中n = 1至3,和/或单糖基和/或寡糖基自由基,条件是R 1和R 2中至少一个基团代表OR 11,并且R 3至R 10可以相同或不同,独立地为一个 另一个,对于相对于UV性质基本上是惰性的基团,可以是组合物 涉及用于制备复合物或包含其的组合物的相应方法及其用途,特别是用于护理,保存或改善皮肤或毛发的一般状况以及用于轻度保护的方法。
