Abstract
Improved storage stability of detergent compositions containing an aluminosilicate material as a detergency builder and sodium perborate in the form of its monohydrate having a specific surface area of more than 5 m.sup.2 /g, preferably more than 7 m.sup.2 /g. Other conventional materials, in particular other detergency builders, and bleach activators may also be present in the compositions.
