BLEACH ACTIVATION

摘要

Peroxy compound bleaching is activated by a catalytic amount of a transition metal complex of a transition metal (Mn, Co, Fe or Cu) with a non-(macro)-cyclic ligand of the formula : preferably 2,2'-bispyridylamine. Bleaching agent and bleach detergent compositions are also disclosed comprising a peroxy compound bleach and said transition metal complex. The transition metal complex is an effective catalyst for activating hydrogen peroxide compounds, peroxyacids and peroxyacid bleach precursors on removing a wide class of stains from substrates, especially texiles and fabrics.
