Free-flowing detergent powder compositions containing sodium perborate monohydrate

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