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: ##STR1## 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.

Bleach activation

An aqueous liquid bleaching composition is described having a pH from 1 to 6.5 and comprising a solid, particulate, substantially water-insoluble organic peroxy acid such as diperoxydodecanedioic acid. This peroxy acid is stably suspended in an aqueous liquid by a structuring combination of anionic surfactant, ethoxylated nonionic surfactant, and fatty acid.

Suspending system for insoluble peroxy acid bleach

An aqueous liquid bleaching composition is described having a pH from 1 to 6.5 and comprising a solid, particulate, substantially water-insoluble organic peroxy acid such as diperoxydodecanedioic acid. This peroxy acid is stably suspended in the aqueous liquid by a structurant combination of secondary alkane sulfonate and fatty acid.

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.
