ABSTRACT:
Aqueous compositions containing an organic peroxyacid such as the mono-potassium salt of 4-sulpho-peroxybenzoic acid (KSPB) would be convenient to employ for bleaching/washing or disinfection especially of aqueous media, but suffer from loss of available oxygen (Avox) from the peracid during storage.
The problem of storage instability can be alleviated to a considerable extent by employing the KSPB in particulate form and incorporating in the aqueous phase a water-soluble potassium salt of a non-reducing acid having a pK.sub.a of below 6, preferably a non-halide. It is desirable to use at least 1% and preferably at least 5% w/w solution of the potassium salt, of which suitable examples are potassium sulphate and nitrate. The pH of the aqueous phase is preferably brought to pH 2 to 3.
