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.
Claims7
A compound in solid, anhydrous form of the formula:
- ##STR4## in which M represents potassium and n equals 1 or M represents magnesium and n equals 2.
A bleach composition having decreased impact sensitivity comprising a buffering agent or pH regulator and KSPB or MSPB, in such relative amounts that a 1% solution of the composition in water has a pH of 7 to 8.5.
A washing composition having decreased impact sensitivity comprising a surfactant and, and containing at least 0.5% w/w KSPB and/or MSPB.
A sanitising composition having decreased impact sensitivity comprising up to 70% alkali metal chloride or bromide, up to 40% KSPB or MSPB and up to 50% surfactant and up to 20% builder.
