Abstract
An aqueous oxidizing composition comprising a xanthine derivative is described. The composition may comprise more than 5% by weight of hydrogen peroxide. The composition may further comprise a lipophilic compound or a surfactant, and may be applied to keratin fibers. It has been unexpectedly found out that xanthine derivatives stabilize hydrogen peroxide compositions during storage.
