Introduction
The following description and examples further illustrate the preferred embodiments of the present invention. Those of skill in the art will recognize that there are numerous variations and modifications of this invention that are encompassed by its scope. Accordingly, the description of preferred embodiments should not be deemed to limit the scope of the present invention.
In preferred embodiments, methods and compositions for delivering menthol into the smoke stream of a smoking article, such as a cigarette, are provided. The methods and compositions utilize compounds including oxalic acid mono(-)menthyl ester and its salts, which yield menthol upon decomposition at temperatures above ambient temperatures (i.e., those to which a pack of cigarettes is typically exposed prior to combustion) but below temperatures reached in the tobacco rod at a distance of a centimeter or more from the combustion cone in a burning cigarette. In addition to decomposing to form menthol...

Abstract
The present invention relates to smoking articles such as cigarettes, and in particular to a method and composition for mentholation of cigarettes. The tobacco rod of the cigarette contains a compound that decomposes upon exposure to elevated temperatures to yield menthol.
Description
BACKGROUND OF INVENTION Menthol, or 2-isopropyl-5-methyl-cyclohexanol, is a cyclic monoterpene. It is a major constituent of peppermint oil, which has a minty taste and odor and which produces a cooling sensation when inhaled or consumed. Menthol is used as a flavorant in a variety of products, including toothpastes, mouthwashes, oral sprays, drugs, cough drops, cough lozenges, analgesic balms, inhalers, chewing gums, hard candies, chocolates, beverages, liquors, lotions, after-shave lotions, shampoos, moist towelettes, perfumes, deodorants, and the like. Menthol is also a popular flavorant for use in cigarettes, pipe tobacco, chewing tobacco, and other smoking materials. It is used extensively because of the refreshing cooling effect it imparts to tobacco smoke. Menthol, however, has a high degree of volatility at room temperature. This volatility makes it difficult to control the concentration of menthol in cigarettes and can result in problems in packaging and handling. Smoking...
