    Preclinical testing of flavors in e-vapor products - Part 1: Selection of representative flavor mixtures for toxicological evaluations using a structural grouping approach

    EHMAN K.D.(1); LANGSTON T.B.(1); KUMAR A.(1); LEE K.M.(1); SCIUSCIO D.(2); VANSCHEEUWIJCK P.(2); HOENG J.(2)
    (1) Altria Client Services, Richmond, VA, USA; (2) PMI R&D, Neuchâtel, Switzerland
    A variety of flavor ingredients are used in potentially reduced-risk tobacco or nicotine products, including e-vapor products. For this work, the ingredients were initially evaluated for quality and purity, which included assessment of food grade and...

    Preclinical testing of flavors in e-vapor products - Part 2: Preparation and stability characterization of representative flavor mixtures

    SMITH C.R.(1); MILLER J.H. IV(1); SHAH N.(1); KUMAR A.(1); LEE K.M.(1); FRAUENDORFER F.(2); GUY P.(2); DIANA P.(2); GLABASNIA A.(2)
    (1) Altria Client Services, Richmond, VA, USA; (2) PMI R&D, Neuchâtel, Switzerland
    GLP guidelines require the characterization of test articles for preclinical biological studies to ensure the identity and composition are consistent from batch to batch and throughout the testing period. For e-vapor products, this would suggest that...
