Abstract The invention provides bleaching and detergent compositions containing a diacyl peroxide of general formula ROOR1 in which R represents a phthaloyl radical and R1 a radical such that ROOR1, ROOR and R1OOR1 are all soluble in mildly alkyaline aqueous solutions. The composistions, optionally containing a persalt such as sodium perboate, preferably in a mole ratio of one mole per mole of diacyl peroxide, are particularly suitable for washing or bleaching at a temperature of from 30 - 60°C. The invention also provides diacyl peroxide compositions desensitized to impact or abrasion by intimate contact with a siluent, e.g. magnesium sulphate, lauric acid or sodium tripolyphosphate and protected against destructive interaction with other components of the bleaching on detergent composition during storage. Preferred diacyl peroxides include diphthaloyl peroxide, especially for coloured fabrics.
