Zusammenfassung:A bleaching composition is disclosed wherein the bleach catalyst is an aggregate comprising manganese (II) cations adsorbed onto an aluminosilicate support, a binder and a phosphate salt; the aggregates have a diameter ranging from at least 250 to about 2000 microns, which aggregates, upon dispersion in water for two minutes at pH 10 and 40°C, leave undissolved less than 5% particles of 125 microns or higher. The base detergent powder comprises a phosphate salt and a peroxy compound. It was found that bleach performance improves by having phosphate salt both in the aggregate and in the detergent powder base.
