Subject: XGT - Cigarette Paper Comparison
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.

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. Product Design:

RL40092 H 754 70 2.7/48,000
3. 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).

Discussion:
No significant differences were seen. 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.
