Bleaching agent compositions and detergent bleach formulations containing them comprise effective amounts of (a) a peroxide compound having a bleaching action; and (b) a catalyst for the bleaching action of the peroxide compound, said catalyst comprising a water-soluble complex of manganese (III) with a multidentate ligand. The amount of complexing agent in the catalyst that supplies the multidentate ligand to form the complex is such that the molar ratio of complexing agent to manganese is at least about 1:1, preferably 10:1 or greater.
