Oxone is the triple salt 2KHSO₅·KHSO₄·K₂SO₄. For almost all applications, the active ingredient in this compound is potassium peroxymonosulfate, KHSO₅. The triple salt has a longer shelf-life than potassium peroxymonosulfate, but releases the same peroxymonosulfate anion upon dissolution.

One advantage of oxone from an industrial point of view is that its dangerous goods classification tends to be Corrosive (Class 8) rather than Oxidising (Class 5). This makes it easier and cheaper to transport compared to other persulfate salts.
