Detergent additive compositions having improved storage stability in granular detergent compositions comprise a storage-sensitive detergent additive material releasably enclosed within a water-soluble glassy matrix of amorphous phosphate having the formula I: (M2O)x(P2O5)y I wherein M is hydrogen, alkali metal, ammonium or a substituted ammonium group, y has a value in the range from 2 to 50, and the ratio of x:y is from 0.7:1 to 1.7:1. The storage sensitive additive material is preferably a multifunctional photo-activator/dye. |
