Abstract
A uniform, continuous sanitizing film can be formed by simultaneously spraying a two-package aqueous sanitizing composition comprising in a first solution a quaternary ammonium salt compound and in a second solution a polymer containing acid functionality. The sprays are directed to areas of substantial overlap resulting in a reaction between the quaternary ammonium compound and the carboxylic acid functional polymeric compound resulting in formation of a water insoluble film.
