Nicotine Reduction in Cigarette Smoke with Acidic Filter Additives
Abstract
Memo details objective, conclusions, experiment/discussion, and recommendations for evaluating the effects of acidic filter additives in the chemistry of cigarette smoke and apply suitable means to reduce the nicotine-to-tar ratio in GCC-Marlboro LS cigarettes. Conclusions include but are not limited to: adding acidic additives reduces the nicotine to tar ratio, nicotine reduction depends on the strength of the acidic additive (pH), acidic substance could probably be used effectively in paper filter plugs, acceptable acids for use with CA are the polycarbonxylic organic acids due to their solubility in triacetin, to reduce the nicotine-to-tar ratio in GCC-Marlboro LS citric acid and ethyl citrate esters are required.
