ABSTRACT:
Improved detergent powder compositions containing at least a detergent-active material, a detergency builder and sodium perborate monohydrate, and method of making such compositions are disclosed, the improvement being that a sodium perborate monohydrate is used which has physical characteristics of specific surface area (SA in m.sup.2 /g) and pore volume (PV in cm.sup.3 /g) such that the formula (SA+31.25 PV-16.25) is greater than zero. The detergent powder compositions comprising said specific perborate monohydrate have less tendency to caking during storage under high humidity climatic conditions and have the further advantage of maintaining their quick bleach delivery in solution owing to said perborate monohydrate which retains its rapid rate of dissolution despite water-uptake during storage.
