Abstract
A stable manganese adjunct for use as a bleach catalyst is obtained by having a manganese (II) cation bound to a 'ligand' forming either a true complex compound, a water-insoluble salt compound, or an ion-binding compound by absorption, which compound is then protectively embedded in a matrix of water-soluble or water-dispersible material. The adjunct is particularly suitable for incorporation in fabric-washing powder compositions containing a peroxide bleach without causing instablity to the composition and brown discoloration due to MnO.sub.2 formation.
