ABSTRACT:
Granular peroxybleach activated detergent compositions are disclosed containing a crystalline activator component having a well-defined particle diameter and a narrowly defined rate of hydrolysis. These compositions have improved stability, particularly with respect to the activator, under prolonged, particularly alkaline, storge conditions. Peroxybleach activator agglomerates having a specific particle diameter and detergent compositions containing these agglomerates are also disclosed. The agglomerating agent is defined through its inertness versus the activator and also in its melting point. The bleach-activator detergent compositions of this invention are stable under prolonged (alkaline) storage thereby remaining substantially unchanged with respect to the appearance and performance characteristics of the freshly prepared detergent composition.
