Abstract
A non-alcoholic effervescent compound for cleaning and disinfecting the mouth, teeth, gums and breath without necessity of alcohol as a solvent. Surface acting agents, or surfactants, are used to reduce surface tension of the compound in solution, facilitating dissolution of all additives including non-soluble oil-containing components. Surface acting agents also produce a foaming effect which loosens bacteria and food off and out from between teeth. The compound eliminates use of alcohol as a solvent, has increased cleaning action from both foaming and effervescence and produces a good-tasting, desirable mouthwash with appropriate flavor concentrations.
