Taste masking of phenolics using citrus flavors

Abstract

An oral rinse, dentifrice, or oral gel composition comprising: a) about 0.01 weight % to about 5 weight % of a citrus flavor, citrus flavor ingredient, or mixtures thereof; b) about 0.01 weight % to about 5 weight % of a phenolic, said phenolic selected from the group consisting of menthol, eucalyptol, methyl salicylate, thymol, triclosan, and mixtures thereof; and c) an orally acceptable carrier. The claimed composition is useful in retarding the development of plaque, treating gingivitis, and reducing the viable population of micro-organisms in the oral cavity of a mammal.
