Conf., 2022, 75, abstr. 58 Partial vapor pressure, activity, activity coefficient and henry’s law vaporization constant at 25 °C of nicotine from binary mixtures with glycerin and with propylene glycol ST. CHARLES F.K.(1); MOLDOVEANU S.C.(2) (1) St. Charles Consultancy, Lewisville, NC, USA; (2) R. J. Reynolds Tobacco, Winston-Salem, NC, USA Electronic nicotine delivery systems (ENDS) vaporize a solution (e-liquid) consisting primarily of the glycerin (GLY) and propylene glycol (PG) with nicotine added. The polyols typically make up 90% or more of the of the e-liquid solution. Nicotine...

Reynolds American, Winston Salem, NC, U.S.A. The tobacco industry is evolving, not just in products but also in processes. What can we do to lower our carbon footprint? One area of interest is in recycling wastewater in manufacturing facilities. After making nicotine products at our facilities,...
TSRC, Tob. Sci. Res. Conf., 2021, 74, abstr. 06 Analysis of (S)- and (R)-nicotine in commercial nicotine samples and e-liquids and (R)-nicotine pharmacology DULL G.M.(1); MOLDOVEANU S.C.(2) (1) RAI Services Company, Winston-Salem, NC, USA; (2) R.J. Reynolds Tobacco, Winston-Salem, NC, USA Nicotine has been studied extensively because of its presence in tobacco products. Because of its chirality, nicotine can exist in two enantiomeric forms; however, the tobacco plant produces predominantly (S)-nicotine with only a trace of...
