<p>A detergent bleaching composition is provided comprising a compound including a specified pentadentate nitrogen-containing ligand. The compound can activate hydrogen peroxide or peroxyacids and provides favourable stain removal properties, particularly in the presence of iron, manganese or copper ions. In addition, an improved stability in alkaline aqueous environment has been obtained, in particular at the peroxy compound concentrations generally present in the fabric washing liquor.</p> |
