Many aspects have been studied not only from a product point of view but also including the development of appropriate methods for measurement and assessment of the sidesbeam smoke (1·2~). Sidestream smoke measurement usually concentrates on PMWNF, nicotine, ea~on monoxide and ca~on dioxide. Ail of these am measured on the fishtail system developed in SauVsmptan(t ~), with only one anall~wl smoking Nn being required to give data on each of these analytes, PMWNF, nicotine and canon monoxide are b~e three major objec~e parameters used to describe mainstream smoke. Ca~n dioxide is monitored because a is the largest combustion product found in sidesbean~ smoke, being several orders of magnitude greater than any other, Other analytical methods have been developed in the past forthe measurement of certain mmpound(s) present in sidesBeam smoke and these methods were used for some early low visibility sidestream smoke developments (17). These analyses are not regularly carried out during the development of low sidestream products because of the time involved, Additionally, the number of analytical methods that exist to characterise mainstream smoke exceeds those that currently can be applied to sidestream smoke. A prototype reduced sideslream product has recently been developed (21) · details in Appendix i. Minor smoke components for bcth mainstream and sidestream have been measured for the following reasons: i. fha product described in Appendix 1 involved the use of a no~standa~d cigarette paper and filter, whilst the blend incPrporated a high level of expandedtobaeco. The effects of thesedesigneiementsonthecombustion cha~aeterides needed to be examined. 2. The product relative to its commercial control offered total sidestream reduction and it was necessary to see if this characteristic was confirmed relative to other cigarette types, With this in mind a question arises as to which other products should be chosen against which to compare the low total sidestream development. The ddsion taken waste use a series of cigarettesfrom the market place in which the product was to be launched initially. The cigarettes chosen should have similar mainstream FMWNF delivery to the development product. ConsequedJy, in this report the sidekam and mainstream smoke deliveries from the development product and a series of products from the French market are recorded and compared, a. 01992 BAT Co, Ltd.

C: I i I; PDF -!::!!::!!::!.f3 StlC.i: Dill RESULTS AND DISCUSSION Product Types Table f details the products used in this exercise and includes data on the blend type and product weight in addlon to the manufacturer and product name. The abbreviations used in b~is table to describe the products will be adopted throughout this report Product tobacco weight is a primary indicator of sidestream yields (1) but it is not possible to say if the lowest tobacco weight commercial product on the French market has been selected, However, the products selected do cover a range of manufacturers and blend types. Physical Measurements Table 2 details these results and shows that the low sidestream development product produced for this exercise had the lowest densi~ and pressure drop of the tobacco rods examined. All but one of the products had a cellulose acetate filter, the exception being the development product which used a Ratio filter manufactured by filtrona (Appendix i). Due to its construction the Ratio filter has very high pressure drop but with low filtration efficiency, The Benson 5 Hedges Ultra Mild used in this study was an old style product of 59 mm tobacco column plus 25 mm filterformat. This hasbeen changed recently to 57 mm plus 27 mm format, Blend Chemistry and Routine Mainstream Delivery Data Table 3 gives bath blend and routine mainstream delivery data. Note the blend chemistry of Ounhill SuperligMs, which is descrbed in Table 1 as Virginia, is in fact closer to that of a US·blended style of product, Another paint to note is the b blend nicotine af'he Gallia produd and the subsequentb nicoSneta PMWNf: ratio in the mainstream, The COta PMWNF ratios for thess products vary over a wide range with the deve~opment product falling withinthisrange. Table 3 confirmsthat all products are of similar mainstream FMWNF classification, ~ 1992 BAf C~. Ud, Do not copy or show to unauthorised persons. C: I i I; PDF -!::!!::!!::!.f3 StlC.i: Dill Semi·Routine Mainstream Deliveries Table 4 details the semi-routine mainstream smoke deliveries far the range of commercial brands and the development sample. The deliveries of the various minor components have been determined using standard methods of analysis (22), For each of the analytes measured some of the commercial brands have deiiveries above and others below those seen for the development product Although the low sidestream smoke developmentsample has an unconventional Eonsbuetion in tenns of cigarette paper, finer and blend composition, these factors do not seem to have combined to produce unusual mainstream smoke characteristics, Routine Sidestream Smoke Yields Table 5 records the sidestream yields of PMWNF, nicotine, carbon monoxide and carbon dioxide, for the range of products using the ZsMajl system attached to an Bpcrt Filtrana 302 smoking engine. Dinerences in pvtf number exist be~een the data in Table 5 and those shown in Table 3 because the fishtail system does not have automatic butt detection available. The development sample produces the lowest yields 61 ail sideslream smoke components measured, with the exception of the nicotine yield for Gallia, This is due to the low level of blend nicotine in the product, This results in a low nicotine weight burnt and hence a low sidestream nicotine yield, and this effect has been documented in the past (4), Overall, the low yields, from the development product are due to the reduced weight of tobacco burned, and the use of low prmeability paper. ~agnesium oxide and sodium acetate then fu~her reduce the sidestream smoke visibility. These factors have been reported in depth in the past and no further detailed interpretation is offered here (12·20), SemERoutine Sidestream Yields The majMtrj of these analytical methods have been reported previously (17), the exceptions being nitrosamine and hydrocarbon analyses. Nitrosamine analysis broadly follows the procedures for mainstream smoke nitrosamine determinations. Total hydroca~oon analysis has been developed specifie~lyfar sidedream smoke studies to give an indication of the total organic content ol the vapour phase of smoke without having to resort to a specific vapour phase Jean. Details or the total hydrocarbon ana~sis can be found in Appendix II, O 1992 BAT Co, ltd. Do not coW or show to vnaubL~wked persons. ?3 C: I i I; PDF -!::!!::!!::!.f3 StlC.i: Dill fable 6 records the yields of these various components. The reductions of the sidestream yields of the development product relative to each of the commercial products are recorded in Table 7, The development product produces the lowest yields of all components with the exception of ammonia where the yield from Dunhil[ Superlights is the lowest measured, The reasons for this are not dear although previous work has shown that sidestream smoke ammonia yields have a very strong Mend dependence with US blends giving higher yields than Virginia products(l6), The development product has a blend with a high proportion of Burley whereas Dunhill SupertigMs is described as a straight Virginia product There are differences in the levels of reduction recorded between the various components e,g, phenols are reduced to a greater extentthan total vapour phase hydroea~ans by the development product. This is because phenols are present in the particulate phase andthe development product has both magnesium oxide and sodium acetate present in the paper that aid the reduction of particulate phase materids, Total vapour phase hydrocarbons an the other hand is a measure cf the gas phase, and here it is predominantly the weigh of the tobacco burned that is the major contributor to the sidestream yield and hence the level of reduction is lower. Similar comments can be made in relation to sidestream PMWNF reductions relative to gas phase CO and C4~ Various produetlprecursor relationships have been established in the past (23·28) for mainstream smoke but work has not been undertaken for sidestream smoke, Consequently no detailed comment can be made on the differences between the yields of minor components of sidestream smoke between different commercial cigarette brands. CONCLUSIONS 1. The low total sidestream development product gives law yields of all sidestream components relative to a series of commercial brands. 2, Mainstream deliveries from the total sidestream development product fall vithin the range produced from brands that are already in the market place, 3, Thus, although the low total sidestrsam development product has an unconventional construction in terms of paper, filter and blend, and it has radically changed the sidestream performance of the cigarette, a has not changed the mainstream performance relat~e to existing market place products.
