Suh SUBJECT: Summary Of Data Comparing New Outer Wrap Paper ( P1961-52-4 ) With The Current Outer Wrap Paper ( P1766-190-3 ). This summarizes data, both performance and sensory perception, comparing the new, lower pH, outer wrap paper with the current outer wrap paper. OBJECTIVE: To determine if the new outer wrap paper provides performance and sensory perception equivalent to the current outer wrap paper and at the same time offer an improvement in color stability. SUMMARY OF RESULTS: All following results are comparisons of the new versus the current outer wrap paper. I. Performance A. Totals, 50 cc/ 30 sec, S.I.P. - No significant differences in deliveries. See attachment I. C. Stress Smoking, 50 cc/ 15 sec, Double Clutch From The 13 Th Puff = No significant difference. See Folder. D. Paper Burn Back and Char Width - No significant difference. See attachment II. E. Color Stability Data - Kimberly Clark Corp.'s Paper Mill has brought to our attention that the current outer wrap paper will not and can not be guaranteed against yellowing before or after shipment to R. J. R. It is in our bets interest to pursue a more color stable product like the lower pH outer wrap paper. In fact, their concern was of such magnitude that they shared the Hunter Color data obtained on the higher pH paper just before and after flavor treatment. Note that the lower " L " value means less brightness and more positive " b " value indicates a more yellow color. Another important point is that the current outer wrap paper will have more variability in color as seen in the higher level of standard deviation. See attachment III. A number of experiments run at Kimberly Clark Corp. support the observation that the current outer wrap paper will yellow upon exposure to the atmosphere, whereas the new outer wrap paper will retain its color even at stress conditions such as exposure to NO2. Some level of NO2 is present in the paper mill via exhaust gases released from trucks. F. Paper Burn Back With Respect To The Level Of Potassium Succinate - A new and important finding from our evaluation of burn back on models is that the lower pH paper is significantly less sensitive to the level of potassium succinate required to provide proper burn back. See attachments IV - VI. II. Sensory Perception A. Q.D.A. Panel - Five attributes broke out significantly and one trend was perceived. Three positive attributes ratings for the new outer wrap paper are more added flavor, BEST COPY more flavor consistency and more burning tobacco taste ( This one was a trend ). Three negative attributes ratings for the new outer wrap paper are less concentration of smoke, more irritating after taste, and more dirty after taste. See attachment VII & VIII. Looking at historical Q.D.A. data on products similar to the control, we find the new outer wrap paper rates in the typical range for all five attributes where significant differences were perceived. B. Weekend Informal Smoking Panel - No significant difference in product preference, both overall and on various attributes. See attachment IX & X. C. Informal Sensory Panel - No significant difference for any of the seven attributes. It is interesting to note that although the Q.D.A. Panel showed less "concentration of smoke " for the new outer wrap paper, this informal panel showed equal " impact " for the two papers. For " off taste " in the later puffs, the new outer wrap paper had almost significantly lower level than the current paper. See attachment XI & XII. D. Room Aroma Study - No significant difference between the two papers, overall. However, among the smokers the current outer wrap paper was significantly better in acceptance ratings. See attachment XIII. RECOMMENDATION: The new outer wrap paper with the lower pH is recommended for the following reasons. 1. There are no significant differences between the new outer wrap paper and the current one in performance. 2. The new outer wrap paper offers a significant improvement in color stability , whereas the current outer wrap paper will not be guaranteed by our supplier to remain white even during shipment. The supplier will refuse agreement of any kind of color specifications on the current outer wrap since that paper will yellow inconsistently, thereby presenting a quality and consistency problem. 3. The new outer wrap paper offers better quality assurance in terms of reduced sensitivity to the level of potassium BEST COPY succinate required to achieve proper burn back. This benefit is important for processing and performance. On the other hand, the current outer wrap paper will have a much narrower range of potassium succinate level required to achieve proper burn back, i.e. small changes in its level can cause either inadequate or excessive paper burn back. Furthermore, another problem presented by the current outer wrap paper is that in the future with larger production run, we can expect more variability in the potassium succinate level than what we have seen up to now. This increased variability will translate to performance ( burn back ) variability. The new, lower pH, paper will be much more tolerant of this potassium succinate level variability due to reduced sensitivity to the burn chemical on performance. Vivian C.
