Beschreibung
Zusammenfassung:	A stable and effective manganese complex for use as a peroxy compound bleach catalyst is disclosed, said catalyst being a water-soluble complex of manganese (II), (III), or (IV) or mixtures thereof with a ligand which is a non-carboxylate polyhydroxy compound having at least three consecutive C-OH groups in its molecular structure. Bleaching composition comprising a peroxy compound and said catalyst, as well as process for bleaching substrates using said catalyst are also disclosed. Preferred ligand is sorbitol and preferred catalyst is Mn-sorbitol complex.
