The Effect of Extractable Components of Tobacco on Smoke Delivery of PRT

Abstract

Reports to develop "a PRT smoking material, it is necessary to adopt procedures for tobacco extraction, extract concentration and impregnation which will give the most acceptable final product. One major criterion of acceptability is smoke delivery of the PRT so that the effect of tobacco extractables on TPM delivery must be considered". Includes sections: (1) Extraction of a flue-cured lamina tobacco with solvents covering a wide range of polarity; (2) Extraction of a PRT with low polarity solvents; (3) Identification of stem constituents which reduce TPM delivery; (4) Exhaustive extraction of a PRT; (5) Effect of substrate; [and] (6) Effect of extract concentration".

Free Nicotine

Introduction of new/unconventional products

Research and development of novel nicotine delivery devices and experimental tobacco designs.

Nicotine transport, transfer, and uptake

Design changes which alter nicotine delivery or effect how the product causes and maintains dependence, including transfer of nicotine from tobacco to smoke, and uptake into the body.
