A detergent additive composition in the form of an extrudate comprising about 75% to about 95% of particulate infusible solids comprising storage-sensitive detergent-additive material and about 5% to about 25% of ethoxylated nonionic surfactant. The storage-sensitive detergent additive material is preferably an organic peroxy acid bleach precursor. When added to detergent compositions, the additive compositions have excellent storage stability and water-dispersibility characteristics.

Detergent additive compositions

Granular laundry compositions comprising a particulate mixture of a water-insoluble natural or synthetic silica or silicate, a finely-divided organic peroxy acid bleach precursor, and an alkoxylated nonionic surfactant. The particulate mixture has a pH in 2% aqueous dispersion of from about pH 2 to about pH 9. The compositions have improved granular physical characteristics, chemical stability and rate of solution/dispersion characteristics. They are useful in bleach activator, bleaching, detergent and laundry additive compositions.

Granular laundry compositions

Textile softening detergent compositions comprise a nonionic detergent, a cationic textile softener, a builder and a water-soluble polyphosphonic acid of the formula ##STR1## wherein n is 2 or more and Z is an organic group of effective covalency n, or a water-soluble salt thereof, and are preferably made by spray drying a mixture of the nonionic detergent and cationic softener on to spray dried carrier granules comprising at least part of the builders.
