and R are selected from H and OR
11
, where each OR
11
, independently of the others, is OH, a straight-chain or branched C

- to C
20
alkoxy group, a straight-chain or branched C
3
- to C
20
-alkenyloxy group, a straight-chain or branched C
1
- to C
20
-hydroxyalkoxy group, 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 a C

n
— groups, where n=1 to 3, and/or a mono- and/or oligoglycosyl radical, with the proviso that at least one radical from R
1
and R
2
is OR
11
, and R
3
is a radical OR

may be identical or different and are, independently of one another, radicals which are substantially inert with respect to the UV properties.
本发明涉及一种具有光保护性能的制剂,包括至少一种式I1的化合物,其中R1和R从H和OR11中选择,其中每个OR11独立于其他OR11,是OH、直链或支链C1-C20烷氧基、直链或支链C3-C20烯氧基、直链或支链C1-C20羟基烷氧基,其中羟基可以与链中的一级或二级碳原子结合,此外,烷基链也可以被氧断裂,和/或C3-C10环烷氧基和/或C3-C12环烯氧基,其中环也可以被—(
CH2)n—基桥接,其中n=1至3,和/或
单糖和/或
寡糖基团,但至少来自R1和R2中的一个基团是OR11,R3是OR11基团,R4至R7和R10可以相同或不同,并且独立于彼此,是与紫外线性质相对惰性的基团。
