Patent ID: 7465411

Claim:
A composition for catalyst-mediated in-situ generation of dioxirane and an oxidizing solution containing dioxirane with an oxidizing solution pH of less than about 6.0, the composition comprising: effective amounts of a transition metal catalyst; potassium peroxymonosulfate; and at least one dioxirane precursor comprising a carbonyl donor compound; wherein when the composition is admixed with water the transition metal catalyst catalyzes the decomposition of the potassium peroxymonosulfate forming a free radical, reaction of the free radical with the carbonyl donor, oxygen addition with the carbonyl donor, subsequent dioxirane formation, and wherein the composition comprises: about 0.001-1 wt. % transition metal catalyst measured as elemental metal; about 40-99 wt. % potassium peroxymonosulfate; 0.99-59.999 wt % carbonyl donor(s); and totaling 100 wt %.
