Abstract

A bleach and oxidation catalyst is provided comprising a catalytically active iron complex including a defined pentadentate nitrogen containing ligand. This type of iron complex can activate hydrogen peroxide or peroxy acids and was found to have favourable stain removal and remarkable dye transfer inhibition properties. In addition, a considerably improved stability of these iron complex compounds in alkaline aqueous environment has been obtained, in particular at the peroxy compound concentrations generally present in the fabric washing liquor.
