Abstract
Wintergreen flavor stability in chalk-based dentifrices containing calcium carbonate as an abrasive cleaning and polishing agent is improved on storage aging by including therein a flavor-stabilizing agent that is an ester selected from the group consisting of a lower acid ester of glycerin in which the lower acid portion is derived from a saturated monocarboxylic acid having 2 to 6 carbon atoms and a lower alcohol ester of citric acid in which the lower alcohol portion is derived from an aliphatic monohydroxy alcohol having 2 to 4 carbon atoms, used singly or in combination. A stabilized wintergreeen flavor composition suitable for use in flavoring chalk-based dentifrices is disclosed, along with a method for improving the stability of the wintergreen flavor in such dentifrices.
