Abstract

Bleach activator granules for use in or with washing and bleaching compositions having a size of from 0.2 mm to 2.5 mm and being composed of: 55% to 90% by weight of at least one bleach activator for percompounds, having a titre in the peracid formation test of at least 1.5 ml 0.1 N sodium thiosulphate; and 10% to 45% by weight of a binding material comprising essentially a mixture of at least two hydratable inorganic salts. The first hydratable salt is either sodium triphosphate, borax or mixtures thereof, the second hydratable salt being a salt having solubility in water of more than 30 grams anhydrous salt per 100 ml at 60 DEG C, a pH of around 7 up to about 11 for 10% solution, and no transition point below 35 DEG C. Preferred second salts are disodium orthophosphate, potassium, triphosphate and magnesium sulphate. The bleach activator granules have satisfactory stability during storage, are of satisfactory mechanical strength and satisfactory disintegrating properties in contact with water.
