摘要

Use of heteroaromatic compound (I) for activating hydrogen peroxide, is claimed. Use of heteroaromatic compound of formula (I) for activating hydrogen peroxide, is claimed. X : CH, CR 5>, CR 6> or N (preferred); R 1>-R 4>H, optionally substituted aryl, optionally substituted (1-6C)-alkyl, optionally substituted (1-6C)-alkylene, NO 2, a halo, CN, trihalomethyl, pentahaloethyl or carboxaldehyde, where the remainders together forms a ring; and either R 5>, R 6>R 1>; or R 5>+R 1>-R 4>, R 6>+R 1>-R 4>a ring. Provided that: at least one of R 1>-R 4>, preferably R 1> is -CH 2-OH. An independent claim is included for an agent (A) for brightening keratin fibers comprising 0.1-20, preferably 2.5-12.5 wt.% of (I). [Image].
