Abstract
A bleach and oxidation catalyst is provided comprising a catalytically active metal-complex having a poly-dentate ligand containing at least 6 hetero-atoms. Such metal-complexes can activate hydrogen peroxide, peroxy acids or molecular oxygen and were found to have both favourable stain removal and remarkable dye transfer inhibition properties. In addition, these complexes can be easily prepared.
