Abstract
The aim of the invention is to improve the cleaning power of washing and cleaning agents, especially with regard to bleachable stains, while avoiding any damage to the textile treated with said washing and cleaning agents. This is substantially achieved by using an electrolytically bleachable species generated by a redox reaction from an anionically substituted 1-hydroxy-2,2,6,6-tetramethylpiperidine, 2,2,6,6-tetramethylpiperidine-N-oxide, or (2,2,6,6-tetramethylpiperidine-1-yl)oxyl.
