Menthol is one of the most widely used flavorants in the tobacco industry. The volatility of menthol is a problem in terms of efficient application to the cigarette, retention during storage, and delivery upon smoking. This study attempts to quantify the movement of menthol within the cigarette, as well as menthol delivery, as a function of where it is applied to the cigarette and as a function of shelf-life. Six sets of cigarettes were manufactured to identical specifications, with the exception of the percentage of menthol applied to the filter tips vs. the tobacco columns. A non-mentholated cigarette was also produced as a control. Menthol content of the filter tips and tobacco columns was determined immediately after manufacture and then periodically for the next eight months. At the same time, the cigarettes were smoked to determine menthol deliveries. These results were then correlated with the original site of menthol application as a function of time. In a c orollary to this study, mentholated filter tips were removed from their tobacco columns at controlled intervals, attached to non-mentholated tobacco columns, and smoked. Similarly, mentholated tobacco columns were detached from their filter tips and smoked on non-mentholated filter tips. In this way, the individual contributions to menthol delivery from the tobacco columns and the filter tips could be investigated. The results of these studies will be presented.
