ABSTRACT:
The present invention provides bleaching or detergent compositions containing phthaloyl peroxide, preferably desensitized by intimate contact with a diluent e.g. magnesium sulphate, lauric acid or sodium trypolyphosphate, and coated to reduce destructive interaction with other components of the detergent or bleaching composition. Optionally the compositions can contain a persalt, e.g. sodium perborate, preferably in a ratio of one mole per mole of phthaloyl peroxide.
The compositions are particularly suitable for washing/bleaching fabric at a temperature of from 30.degree. to 60.degree. C.
