Aqueous foam containing chlorine dioxide and preparation and use thereof

Abstract From the Canadian patent

An aqueous solution preferably an aqueous disinfectant, solution containing chlorine dioxide and which is capable of forming a foam, and methods for the preparation and use thereof. An aqueous disinfectant solution capable of forming a foam is prepared by adding a foaming agent, i.e. a suitable surfactant to water. Chlorine dioxide may then be added to the solution or it may be generated in situ by reacting an oxidizing agent a, cationic exchange resin in the acidic form or an acid with a, metal chlorite dissolved therein. The resultant foam solution may subsequently be foamed by being mixed with air in a foam generator. The foam solutions of the instant invention are useful as cleaning …
