Abstract

Reports on the status of the XGT-cigarette paper comparison. Notes the objective is to "observe T/N ratio changes in cigarettes made with different porosity papers and at varied air dilutions (VUL 85 configuration). Discusses the experiment's design, the materials used, such as 29 Coresta cigarette paper and 44.1 Coresta cigarette paper. Includes chart listing Test Code, Cigarette Paper, Air Dilution, and Tow Item. Also includes a chart listing the results, Percentage of Air Dilution, Carbon Monoxide, Puff Count, Nicotine, Tar, and the T/N ratio. Determines that there was no significant difference. Plans for next steps, for example using a low efficiency filter versus PIC at varied air dilution, and holding the cigarette paper constant.

Hypothesis: Use of filters, paper, and ventilation
Modification of tobacco products through use of filters, paper, and ventilation, and measuring effects on dependence, behavior, and toxicity.; 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.

RJR INTER-OFFICEMEMORANDUM SUBJECT: XGT-Cigarette Paper Comparison DATE: June 1, 1988 TO: XGT File FROM: Karen M. Womble Objective: To observe T/N ratio changes in cigarettes made with different porosity papers and at varied air dilutions (VUL 85 configuration) Experimental Design: 1. Materials: 719 (1005471) cigarette paper - 29 Coresta (1.7% citrate) 754 (1005469) cigarette paper - 44.1 Coresta (1.0% citrate) Tow item - 2.7/48,000 - VUL Tipping paper (1005856) - VUL VUL tobacco blend #D143 (no topdressing) 2.

All products were made in Bob Bost's area. After making, products were laser perforated by Bill Casey's group in OD at the desired levels of 30, 50 and 70%. Products were then dilution selected at each level and submitted for FTC smoke analysis of tar, nicotine and CO (test code-RL40092). Results: (Attachments) 719 Cigarette Paper (29 Coresta, 1.7% citrate) Code % Air Dilution CO mg/cig Puff Count Nicotine mg/cig Nicotine mg/puff Tar mg/cig Tar mg/puff T/N RL40092 A 0 13.9 6.3 .65 .103 9.5 1.51 14.6 RL40092 B 30 11.8 6.9 .61 .088 7.8 1.13 12.8 RL40092 C 50 7.3 7.2 .44 .061 5.2 .72 11.8 RL40092 D 70 3.1 7.8 .24 .030 2.4 .31 10.0

Results were as expected and since established ranges for porosity targets overlap, 719 (29 Coresta) vs 754 (44.1 Coresta) were not different enough to show changes in T/N ratios. Next Steps: Use a low efficiency filter (8.0/40,000) vs PIC (with a 2.1/48,000 CA plug) at varied air dilution (30, 50, 70%). Hold cigarette paper constant (856-29 Coresta, .55% citrate) and use VUL blend #D143. This is to observe T/N changes comparing CA vs PIC filter at a wider range of air dilution.
