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 pH 2 to 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.
