Abstract
A non-alcoholic delivery system for active ingredients is disclosed which does not require the use 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, spray-dried flavoring oils. Surface acting agents also may produce a foaming or effervescent effect, if desired. One formulation produces a good-tasting, desirable mouthwash with appropriate flavor concentrations, as well as other products.
