Abstract
An improved antimicrobial composition is described as a liquid concentrate. The liquid concentrate includes a complex resulting from an in-situ reaction of a cation source, an oxidant, a halide source having at least one iodine atom, and a non-mineral acid, or a mixture of a non-mineral acid to about 50% of a hydrophilic solvent by volume.

An antimicrobial composition concentrate comprising an inter-polyhalide having at least two halide atom types and at least three total halide atoms selected from ICl2−, ICl3−, ICl4−, IBr2−, IBr3−, and a mixture thereof, the inter-polyhalide being a reaction product of ingredients which comprise:
- (a) a cation source;
- (b) an oxidant;
- (c) a halide source comprising a metal halide, a halogen, or a mixture thereof, wherein said halide or halogen comprises at least one iodine atom;
- and
- (d) a non-mineral acid, or a mixture of a non-mineral acid and up to about 50% of a hydrophilic solvent by volume.
