Abstract

The invention provides ethanol-free liquid oral care compositions comprising cetyl pyridinium chloride which do not have an unacceptably bitter taste, e.g. mouthwashes, toothpastes, throat sprays, and breath sprays that are substantially free of ethanol, e.g., comprising (i) an antimicrobially effective amount of cetyl pyridinium chloride (CPC), (ii) one or more flavoring oils which are substantially insoluble in water at room temperature, and (iii) water, wherein the ratio of the CPC to the one or more flavoring oils is from 1:1.5 to 1:2.5, as well as methods of making and using the same.
