Abstract: The present invention concerns a method of making manganese ion-containing catalyst salts, which comprise a mononuclear or dinuclear Mn (III) and/or Mn (IV) complex based on cyclic triamine ligands and a non-coordinating silicate-based counterion. The invention also concerns compositions comprising such salts and bleaching formulations comprising the salt and a peroxy compound. The salt, and formulations comprising it, are suitable for use in catalysing oxidation, for example as a component of a laundry or dishwasher bleaching composition. The invention further relates to methods of oxidising with the bleaching formulations described herein.

Abstract: The present invention concerns the treatment of substrates with a preformed transition metal catalyst in an aqueous solution. The transitional metal catalyst is a dinuclear Mn transitional metal catalyst and its ligand has the following formula (I): and p is 3.
