<p>The incorporation of many percarboxylic acids, which otherwise could be incorporated in household formulations as disinfectants and/or bleaching agents, especially at hand-hot temperatures, is precluded or hindered by their adverse physico-chemical properties, such as a propensity to decompose too quickly during storage or explode on impact or when subjected to pressure. The invention provides a stable and effective selection of organic percarboxylic acids which satisfy the general formula (1): X-Ar - CO - NY - R(Z) - CO - OOH in which X represents hydrogen or a compatible substituent, R represents -(CH2)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 aralkyl group provided that at least one of Y and Z is not hydrogen if n = 3. The invention also provides bleaching, washing and disinfecting compositions containing such peracids and processes using them for such purposes.</p> |
