Particulate bleaching detergent compositions containing zeolite map and a stable bleach catalyst

摘要

A particulate bleaching detergent composition, preferably having a bulk density of at least 700 g/l, comprises an organic surfactant system, a zeolite builder and a bleach system. The bleach system includes a peroxy bleach compound, and a transitional metal catalyst which comprises a source of Mn and/or Fe ions and a defined macrocyclic organic ligand. The zeolite is zeolite P having a silicon to aluminum ratio not exceeding 1.33 (zeolite MAP). The compositions show improved stability of the bleach catalyst against discoloration on storage, as compared with similar compositions containing conventional zeolite A.
