Abstract
Abstract The present invention provides low concentration chlorous-acid generating compositions useful for oral hygiene. The compositions are effective oral disinfectants which do not have the strong unpleasant taste of chlorine and are useful in reducing plaque. The invention also concerns processes for making the inventive compositions and methods for using the same.
