Abstract
Abstract Increased energy costs have stimulated a demand for peroxygen compounds that are effective at ambient to hand-hot temperatures, but peroxyacids and acyl peroxides tend to suffer from one or more of poor thermal stability, or sensitivity to impact or moisture, thereby rendering their manufacture or storage hazardous, or from poor solubility. The instant invention provides salts of the formula (in anhydrous form): ##STR1## in which M represents potassium and n=1 or M represents magnesium and n=2. The solids can be incorporated in low temperature bleaching compositions, in washing compositions, in sanitizing compositions or in disinfection/sterilisation compositions.
