Abstract
It has been found that the addition of specific levels of sodium, advantageously in the form of sodium carbonate, to low sodium level binder, e.g., ammonium alginate, containing carbonaceous fuel compositions results in dramatic changes in the performance of both the fuel element themselves and, cigarettes (or other smoking articles) incorporating the fuel elements. These performance differences include variation in the yields of aerosol and/or flavorants. The addition of sodium carbonate to the fuel elements greatly improves the smolder rates and also improves puff calories, without overheating the cigarette, thereby resulting in substantial improvements in total (and puff by puff) aerosol yield.
