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