    摘要: The invention relates to a process for stabilizing particulate alkali metal percarbonate by coating by coating it with an aqueous solution, preferably concentrated, of a complex formed from a boric acid or borate and an organic diol, polyol or hydroxycarboxylic acid, to the resulting coated product, and to compositions including the product. The coating can additionally contain an alkali metal neutral salt such as sodium chloride or sodium sulphate.

    摘要: A process for stabilising percarbonate by coating with a coating agent. The percarbonate particles are treated with a concentrated aqueous solution containing at least one boron compound selected from the metal and ortho boric acids and at least one phosphate. Water is removed to provide the coated percarbonate particles which are useful in bleaching and washing compositions.

    摘要: An aromatic peroxyacid which satisfies the general formula (1):X--Ar--CO--NY--R(Z)--CO--OOH (1)in which X represents hydrogen or a compatible substituent, R represents --(CH2).sub.n -- in which n=2 or 3, and Y and Z each represent independently a substituent selected from hydrogen or an alkyl or aryl group or an aryl group substituted by a compatible substituent or alkaryl group provided that at least one of Y and Z is not hydrogen if n=3. The peroxyacid is an effective bleaching and disinfecting agent which has a long shelf life and good resistance to impact, pressure and thermal shocks, and is useful in bleaching, washing and disinfecting compositions.
