Abstract

The cleaning performance of washing and cleaning agents, in particular with respect to bleachable stains, was to be intensified without resulting in damage, in the context of use, to the textile treated therewith. This was achieved substantially by employing a bleaching-active species generated electrolytically from an organic mediator compound using a redox reaction.
