         7 . A method for delivering a flavorant containing at least one hydroxyl group comprising heating, combusting or hydrolyzing an ester containing an alcohol moiety that is a flavorant and an acid moiety that is a polycarboxylic acid, wherein at least one of the carboxyl groups of the polycarboxylic acid is in the form of a salt, and wherein there is at least one carbon atom between the carbonyl carbon of the ester and the carboxyl carbon forming the salt. 
     
     
         8 . The method of  claim 7 , wherein the ester containing an alcohol moiety that is a flavorant and an acid moiety that is a polycarboxylic acid is incorporated in a smoking composition. 
     
     
         9 . The method of  claim 7 , wherein the ester containing an alcohol moiety that is a flavorant and an acid moiety that is a polycarboxylic acid is incorporated in a component of a smoking article. 
     
     
         10 . The method of  claim 7 , wherein the ester containing an alcohol moiety that is a flavorant and an acid moiety that is a polycarboxylic acid is incorporated in a heated or combustible product. 
     
     
         11 . A manufactured article comprising an ester containing an alcohol moiety that is a flavorant, and an acid moiety that is a polycarboxylic acid wherein at least one of the carboxyl groups of the polycarboxylic acid is in the form of a salt, and wherein there is at least one carbon atom between the carbonyl carbon of the ester and the carboxyl carbon forming the salt. 
     
     
         12 . The manufactured article of  claim 11 , wherein the article comprises a tobacco rod, and wherein the ester has been applied to the tobacco rod. 
     
     
         13 . The manufactured article of  claim 11 , wherein the article comprises a component of an electrically heated cigarette. 
     
     
         14 . The manufactured article of  claim 11 , wherein the article is a combustible or heated item of manufacture. 
     
     
         15 . The article of  claim 14 , wherein the article is a fragrance stick, room deodorizer, incense or fireplace log. 
     
     
         16 . The article of  claim 11 , wherein the article is a comestible. 
     
     
         17 . A comestible product comprising a comestible material and an ester containing an alcohol moiety that is a flavorant, and an acid moiety that is a polycarboxylic acid wherein at least one of the carboxyl groups of the polycarboxylic acid is in the form of a salt, and wherein there is at least one carbon atom between the carbonyl carbon of the ester and the carboxyl carbon forming the salt. 
     
     
         18 . The comestible product of  claim 17 , wherein the comestible material comprises a foodstuff or beverage. 
     
     
         19 . The comestible product of  claim 17 , wherein the comestible material comprises an oral care composition.
