POC/Bl't,f/46M 17th June 1987 PROJECT ALPHA - CAPRI STUDY SIDESTREAH BRAND SURVEY SUHMARY Due to the interest in the Brown & kfilliamson product Capri a sldestream brand analysis survey has been undertaken on the sidestream yields from a variety of United States Domestic produ=s. The data in the memo shows that Capri has the lowest sidestream PMk~IF delivery of all the U.S. Domestic brands currently tested. -i- J 0 0 (_,.m r~ 0 I'~ll7 B A.T IU.)~. axmd Ezp,~) l ,m,ed T)us repL-,rz musz no( be cnp&ed ~ s,h~,'n to unaudtonsed pe.rsons. ......................................

-l- I. INTRODUCTION As a result of interest expressed in low circumference cigarettes since the launch of Capri on the US Market, a brand survey of nine United States Domestic Market products has been undertaken. In addition an internal control cigarette and a Virginia product have also been tested. The cigarettes have been subjected to sidestream analyses using the Fish-tail system (1). Yainstream, blend and physical measurements have also been done on the cigarettes. The data has been collated in this Technical Mamorandum and observations/explanations are given where possible on the sidestreem performance of these products. 2. ~'THODOLOGY Standard BAT (UK&E) R&DC analytical methodology has been used throughout this study. The butt length smoked to with all cigarettes was overtip plus 3 mm. Sidestream yields have been determined on the Fish-tail system as mentioned previously. Differences between puff number exist between the sidestream and mainstream analyses, this is because currently automatic butt detection is not available on the Fish-tail systm. 3. RESULTS AND DISCUSSION (a) Sidestream Yields Table 1 gives the sidestream yields on the products ranked in order of decreasing sidestream PMWNFyield. Additionally, in Table I the sidestream yields are expressed in terms of per gram of dry tobacco (or nicotine) burnt, i.e. taking into account the rod length, density, moisture content and blend nicotine results, see Tables 3 and 4. ~) l~14T B A T I L~ IC. aa,l Et~w'¢; I .reLied Thins rc~w-t must ~oc be ¢nl~cd or ,~'to~n Lo u~suthonscd pcrlloe=s.

Virginia Product. In terms of PMI~F Capri is the lowest product tested within this series being 33% below Virginia slims. It would be expected that as the rod weight burnt, decreased (see Table 5) the sidestream yield would fall. This is plotted in graphical format in Figure I, Clearly with the exception of Dotal Lights and Capri no such trend is apparent. 0 0 L~4 r,o (j~ C.N (~ I~T B A T iL" K ~ IZ~¢~w~i L=m,~e,~ Th~$ rep=~ mutZ ao~ be ended or ,.horn to una~on~ pe~ons BATCo document for Legal Services • Health Canada 20 May 1999

-3- The reason for this is unclear particularly since other linear trends have been illustrated in the past relating sidestream P~F to tobacco rod weight burnt (Z,3). However, these results relate to products which had the same blend type incorporated in them, and with a product survey of this nature the blend composition and PMWNF potential of each material is unknown. To illustrate this point data is given in Appendix I which shows the sidestream PMW~F potential of 100% Virginia lamina and 100% Virginia stem. Similar points can also be raised on sidestream carbon monoxide and carbon dioxide deliveries. Examination of sidestream nicotine yields is more meaningful because the sidestream nicotine yield can be influenced by the blend nicotine, this is illustrated in Figure Z. In this situation the sidestream nicotine yield is plotted against the nicotine weight smoked {calculated fro the rod weight smoked, the moisture content and the blend nicotine). Regression analysis of this data provided the following equation: Sidestream nicotine = 0.333 x nicotine weight smoked + 0.08. y = M . X + C where the RZ value was 0.9 and the intercept is not statistically significantly different to the origin. Thus, the sidestream nicotine yields are explainable within the product survey, being related to the nicotine weight smoked. Examination of the calculated sldestream yields per gram of tobacco burnt in Table I shows that for carbon monoxide and PMWNF, Capri has the highest yield. Alternatively, the greatest PI~F and carbon monoxide sidestream production efficiency comes from Capri. This is not surprising bearing in mind Capri is virtually an all lamina blend with no stem and little reconstituted tobacco (see also Appendix I). However, because of the low rod weight of Capri on a per cigarette basis it is still the lowest sidestreem Pt~F yield of the brands surveyed in this study. o ~) I'~.W7BAT II.:K and E,p,,nlL,mJted T~$r~l~nmusZ,~ocbecnp~edorsho~etounauthoesc,,d pef-.~a$. w C) O U'I P,J (..n BATCo document for Legal Services • Health Canada 20 May 1999

Ooral Lights has a sidestream PMI~F yield only slightly above that of Capri, this is due to the low rod weight of the sample (Table 5) because of a high level (27.8%) of expanded tobacco being present in the blend. Similar comments apply to the gas phase results for carbon monoxide and carbon dioxide. The sidestream nicotine yield is lower in Doral Lights than Capri, this is a consequence of both the low tobacco rod weight of Doral Lights and the low blend nicotine level (Table 4) relative to Capri. (b) Pressure Drop and Ventilation Measurements Table 2 details these results. Essentially the rod pressure drops are similar for the majority of these products but with the low circumference cigarettes the rod pressure drops rise as reported previously (2). The paper permeability range covered in this survey will have no effect on the sidestream performance of these products.
