Abstract

A composition for retarding bacterial, fungal and viral contamination and mold growth containing an acid releasing polymer, a hydrophilic material, and a chlorite anions (12).
Each component of the composition has a particle size of not more than about 1,000 angstroms. The composition is substantially free of water and capable of releasing chlorine dioxide upon hydrolysis of the acid releasing polymer.
