Abstract

The aim of the invention is to improve the cleaning power of detergents and cleaning agents, especially with regard to bleachable stains, while avoiding any damage to the textile treated with said detergents and cleaning agents. For this purpose, a bleach catalyst in the form of a complex of Fe—, Mo—, Mn— and/or W with a ligand having a skeleton of formula (I) is used.
