Bleach and oxidation catalyst

A bleach and oxidation catalyst is provided comprising a catalytically active iron, manganese or copper complex including a specified pentadentate nitrogen-containing ligand. The metal complex can activate hydrogen peroxide or peroxyacids and provides favourable stain removal properties. In addition...

Beschreibung
Zusammenfassung:	A bleach and oxidation catalyst is provided comprising a catalytically active iron, manganese or copper complex including a specified pentadentate nitrogen-containing ligand. The metal complex can activate hydrogen peroxide or peroxyacids and provides favourable stain removal properties. In addition, a considerably improved stability of these metal complex compounds in alkaline aqueous environment has been obtained, in particular at the peroxy compound concentrations generally present in the fabric washing liquor.
