Abstract
Abstract The present invention provides bleaching or detergent compositions containing a cycloaliphatic peroxyacid of general formula: ##STR1## WHEREIN O ≦m ≦5, O ≦n ≦5 and N+m≧ 1, And mono or diethylenically unsaturated derivatives thereof, and processes for washing/bleaching using such peroxyacids, preferably at a temperature of from 30 to 60° C. The peroxyacids can be generated in situ by hydrolysis or perhydrolysis of the corresponding diacyl peroxide. The peroxyacid and diacyl peroxide can be desensitized by intimate contact with a diluent e.g. lauric acid or magnesium sulphate and coated to reduce destructive interaction with other components of the detergent or bleaching composition.
