POC/BI"N/4~ M 17th June 1987 PROJECT ALPHA - CAPRI STUDY SZDESTREAM BRAND SURVEY SU/~Y Due to the interest in the Brown & Williamson product Capri a sidestream brand analysts survey has been undertaken on the sidestream yields from a variety of Unfted SCares Domesttc products. The data in the memo shows that Capri has the lowest sidestream PNMtF delivery of all the U.S. Domestic brands currently tested. -i- I'~?

-I- 1. ZNTRODUCTION As a result of interest expressed in low circumference cigarettes stnce the launch of Capri on the US ~et, a brand survey of nine United States Domestic I~rket prodOcts 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 (l). Yainstream, blend and physical measurements have also been done on the cigarettes. The data has been collated in this Technical Memorandum and observations~explanations are given where possible on the sidestream performance of these products. 2° ~THODOLOGY Standard BAT (L~&E) R&DC analytical methodology has been used throughout this study. The butt length smoked to with all cigarettes was ove~cip plus 3 mm. Stdestream yields have been dete~ined on the Fish-tail system as mentioned previously. Differences between puff number exist between the stdestream and mainstream analyses, this is because currently automatlc butt detection Is not available on the Fish-tail system. 3. RESULTS AND DISCUSSION (a) Sidestream Yields Table 1 gives the sldes~ream yields on the products ranked in order of 'decreasing sidestream PMWNF yield. 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.

Virginia Product. In terms of PMWNF 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 Doral Lights and Capri no such trend is apparent. 0 r~ (~ I,~x? iS A T :t.:.~. a~l [,:~,nJ ~m*ee, J Th,s repro musx no~ be ended or sho,,n to us~xumonsed pesr,,on$.

-3- The reason for this is unclear particularly since other linear trends have been illustrated in the past relating sidestream P~MiF to tobacco rod weight burnt (2,3). However, these results relate to products which had the same blend type incorporated tn them, and with a product survey of this nature the blend composition and Pt~NF potential of each material is unknown. To illustrate this point data is given in Appendix I which shows the sidestream PIlaF potential of 100% Virginia lamina and 100% Virginia ste~. Similar points can also be raised on sidestream carbon monoxide and carbon dioxide deliveries. Examination of stdestream 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 from 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 R2 value was o.g and the intercept is not statistically significantly different to the origin. Thus, the sldestream 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 1 shows that for carbon monoxide and PI~F, capri has the highest yield. Alternatively, the greatest PM~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 sidestream PM~F yield of the brands surveyed in thls study. J 0 0 U1 ClibPDF - W',Y',/VVmfaS~[io.colll

Dora1 Lights has a sidestream PMF 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. Simt]ar comments apply to the gas phase resu|ts for carbon monoxide and carbon dioxide. The sidestream nicotine yield Is lower In Dora1 Lights than Capri, this is a consequence of both the low tobacco rod weight of Dora1 Lights and the low blend nicotine level (Table 4) relative to Capri. (b) Pressure Drop and Ventilation I~asurements 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 rtse as reported previously (2). The paper penmeabt]ity range covered in this survey wtll have no effect on the sidestream performance of these products.

-7- (d) Blend Data Table 4 contains the blend data. Ignoring Capri the BAT and PMlip Y~rris products all contain about approximately 10% expanded tobacco whereas the R.J. Reynolds products contain more (~ 14% for Camel and Vantage and 28~ for Dotal Lights). This causes some loss in puff number with these products (Tab|e 6). The sugar ch~istry for all products except ~nson and Hedges and ~Tg is typical of U.S. blended style products. Interestlngly the two previously mentioned Vlrglnia products have the highest blend nicotines and highest sidestream nicotine yie|ds (Table 1) of the pr6ducts tested.
