A composition comprising a stable solution of potassium monopersulfate having an active oxygen content of from about 3.5% to about 6.8% by weight and a maximum SO4 content of about 5.5% by weight.
A process for the preparation of a solution of potassium monopersulfate having an active oxygen content of from about 3.5% to about 6.8% by weight and a maximum SO4 content of about 5.5% by weight comprising a) mixing to form an equilibrated slurry:
- i) solid 2KHSO5.KHSO4.K2SO4, ii) a quantity of water insufficient to completely dissolve the solid, and iii) an alkaline material;
- and b) separating undissolved solids to obtain a stable solution.
