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