There is provided a bleach catalyst composition in the form of non-friable composite granules, whereby each granule is substantially free from easily oxidisable organic materials and comprises a carrier material, a binding agent, and a bleach catalyst including a source of Mn and a ligand, said ligand being a macrocyclic organic compound of the formula (I): [NR?3-(CR1(R2)¿q)t]s wherein t is an integer from 2 to 3; s is an integer from 3 to 4; q is zero or one; R?1 and R2¿ are each independently selected from H, alkyl, aryl, both optionally substituted; and R3 is independently selected from hydrogen, alkyl, aryl, both optionally substituted. These bleach granules have been found to give improved bleaching performance on specific stain-types, particularly on cocoa stains. |
