Abstract
An oxidizing species is described herein as a reaction product through an in situ preparation combining a protonizable phosphorus or sulfur compound, and a halide source at controlled proportions in an aqueous, non-aqueous, gel, aerosol, solid-phase or powdered media. The oxidizing species can be used to reduce microbial and viral populations on a surface or object or in a body or stream of water. The invention thus finds applications as a bleach, sanitizer, oxidant, or in any other application in which an oxidizing agent can be beneficially used alone or in a formulation.
