The effects of several inorganic salts on the combustion of cigarette and the transfer of nicotine into cigarette smoke have been investigated. Ferric, ferrous, ammonium, magnesium salts and chlorides or sulfates depress the combustibility. Contrary to this, potassium, calcium salts, nitrates and carbonates promote it. The combustion-zone temperatures of cigarettes are within the range from 815°C to 857°C, they are not significantly affected by an addition of inorganic salts. Magnesium nitrate, zinc nitrate and potassium phosphate improve the whiteness of cigarette ash, but the other salts rather darken it. Any relations, however, are not recognized between the whiteness of ash and combustibility of cigarettes. The amounts of nicotine transferred into smoke can be reduced by an addition of inorganic salts, among which magnesium is the most effective.
