Method of Making a Composition Containing A Stable Chlorite Source

Abstract: 

A process for preparing a composite which provides sustained release of chlorine dioxide which includes mixing a hydrophilic material containing an amine and a base with a hydrophobic material containing an acid releasing agent, the hydrophilic and hydrophobic materials being adjacent and substantially free of water, to form a mixture. The mixture is exposed to chlorine dioxide which reacts with the amine to form iminium chlorite which is decomposed by the base to form a chlorite salt within the hydrophilic material. The hydrophilic material is capable of releasing chlorine dioxide upon hydrolysis of the acid releasing agent.
