INTEODUCT TON
An exam£naC£on (i) of the South African market revealed a distinct
d£ffe~ence between brands produced by United Tobacco Co. (South) (a B.A.T
company) and brands produced by Rmabrandt Group Ltd. (RoChmans Znternation81
Group).
The investiKation included all brands which had a lZ or more share
of the market. The resulting selection consisted of both "bleuded" and
"flue-cured" types from both companies in a total of 21 brands. The
brands were examined by:
(a)
(b)
Co)
Oil/wa~er partition analysis.
Standard brand analysis.
Smoke panel assessment of Lmpact and irri~tlon.
Ze was possible to Kroup the brands by manufacturer and blend type
usinK the experimental data. The Rembrandt brands were shown to be of
ewo dlst£nct types: (i) "blended" produces characcarised by high O/~'P
pyridines, extraceable n£cotine snd impact coupled with low O/~TP furfurals
and =educing sugars and (i£) "flue-cured" products character£sed by
moderate O/WE pyridines, low extractable nicoeine and impact coupled
with hiKh O/WP £urfurals and reducing sugars. The U.T.C. products
generally fell between (i) and (i£) in produce terms; furthermore, no
clear analytical distinction be~weem U.T.C. "blended" and "flue-cured"
products was found.
~ollowinK ~his clarlfica~ion of the product differences between
manufacturers, experimental products were received from Soutb Africa
for evaluanLon. The objective of this experLment was to modify the
BENSON & HEDGESfEMBASSY blend so that one or both of these brands could

be matched to Re=he•us KS in product ceres; additionally the
LUCKY STKXKE/HUNTER blend was also modified in an attempt to achieve
LexinEton LS product characteristics. The experfmental products were
examined by the same cechniques, (a)-(c) above, which discriminated
between manufacturers and blend types. In addition, some smoke vapour
phase analyses were conducted.
As well •s the above experiments involvinE blend revisions, some
further experiments were conducted to explore the effects of chanEes
in cellulose acetate tow.
EXPEEIMENTAL SAMPLES
The blend compositions of the experimental ciEarettes which have
been examined are listed in Table I. In addition, the composition of
EMBASSY (and BENSON & HEDGES) and LUCKY STRIKE (and HUNTER) at the outset
of the project, are shown in she Sable. During the course of the project,
two fur=her s•ts of co~ercial EMBASSY or B. & H. and LUCKY STRIKE were
received, which had incorporated some of the modifications suaEested
by the experimental tiE•retie evalu•nlons. In this report, the original
commercial samples - reported in (i) - have been coded ~, whilst
subsequent co---erci•l samples have been coded ~ and ~, in
chronological order, reflectinK the development of the brands.
The experimental smnples were 818o received in 1~t,J'o separate sets,
as detailed below.
First Series
Flue-cured Cigarettes (EO~ Elt E2)
This enabl•d, throulh E0, an examination of • major blend revision;

replacement of a subscantlal portion of imported flue-cured by domestic
flue-cured. In addition the attributes of domestic and imported flue-cured
could be ascertained via examination of E1 and E2 respectively.
Blended Cigarettes (L~ N.P B, R, T)
This enabled through L and N (L is flavoured N), an examination of
blend revisions also; in this case, elimination of PCL and incorporation
of domestic light air-cured toEether with increased levels of domestic
Burley. Evaluation of B, I% and T enabled the attributes of do~-estlc
Burley, imported Burley and domestic liEht elf-cured respectively, to
be evaluated separately.
At this sCaEe, commercial brands, coded ~ in this report, were
also received, which had been slightly modified alone the lines of EO
and L/N. Relevant competition brands - Rottnnans and Lexington - were
also re-examined.
Second Series
Flue-cured Cilarettes (E3p E4~ ESp E6)
E6 was a re-zwke of EO. E3 and E4 tested proEressive decreases in
imported flue-cured content with respect to EO/E6, whilst E5 tested
re-imtroduction of PCL into E3.
Blended Ci~arettes~ (NL! B2r B3r B4r BS)
NL was a remake of N and L. B2 and B3 tested the effects of sliEht
increases in imported flue-cured and domestic Burley, respectively, at
nhe expense of the domestic liEhr air-cured. B4 and B5 were B2 and B3
with PCL add-on, respectively.
At this stage, commercial brands, coded ~ in this reporn, were
also received, whLch had been further modified in the EO/E6 and N/L/NL
direcUion. Relevant competition brands were aEain also received.

Ln addition, filter rods of 5Y/50 and 8Y/35 filament/total denier
were examined to test the effect of filter modification. The majority
of experimental products were tipped with 5Y/38 fil~ars.
BLEND AND SMOKE ANALYSES
Physical aspects of the experimennal and branded CiKarettes are
detailed in Table 2; blend and smoke information is presented in Table 3.
As in the recent report (I), extractable nicotine and reducing 8uKar
data has been plotted, since this plot usefully dlscri~natad between
manufacturers and blend types. Consequently, this plot will help to
indicate whether the experimental blends are acquiring Rembrandt-llke
characteristics, and which tobacco types should be included to improve
the 'match' to Rembrandt products.
The following observations were made from this data'-
Pressure Drop
Imported (E2) flue-cured tobacco pEoducad a hiKher pressure drop
tobacco rod than domestic (El) flue-cured tobacco althouKh both rods have
very similar packing densities. EO i8 as expected from its 50:50 EI-'E2
composition, intermediate in pressure drop. The tobacco rod pressure
drops of EMBASSY and Roth~ans resemble E2 and El respectively. This
may suKgest increased domestic usaKe by Rembrandt (with respect to U.T.C.)
or be due to the lower density of the Rothmans tobacco rod. Imported
Burley (E) results in a markedly hisher tobacco rod pressure drop than
domestic Burley (B) and liKht air-outed (T) tobaccos; this, however,
m£sht be explained by ~he higher density of the R tobacco rod.

2. Nicotine/Susars
E1 (domestic) tobacco contained less n~cotine but more sugars than
E2 (imported). The same directional difference was noted (I) for
Rembrandt and U.T.C. flue-cured brands, the Rembrandt brands containing
less blend nicotine b=t hisher sugars than U.T.C. brands. This reinforces
the impression that Rembrandt make greater use of domestic flue-cured
grades. The E3-E5 series was higher in sugar content than EMBASSY
and E2, and well matched to Rothmans.
Imported Burley contained more nicotine than domestic Burley. The
Burleys and air-cured samples generally contain more nicotine than the
flue-cured samples. The low sugar content of these samples is reflected
in the lowered sugar content of L/N/NL, and B2-B5 which contain more
of these types of tobacco than LUCKY STRIKE ~. B3 approached Lexington
in terms of suKar content; the sugar levels imply--,oh greater usaKe
of Burley and a~r-cured in Lexington with respect to LUCK~ STRIKE.
3. Filter Characteristics
The flue-cured and blended series were examined using 5Y/38 denier
acetate filters w~th the exception of gO, El, E2, which were supplied
with lower pressure drop 8Y/35 filters. At a later stake of the project
5Y[50 and 8Y/35 filters were supplied for comparison with 5Y/38 filters.
The variations ~ filter pressure drop and plasticiser content are shown
in Table 2 and are co~manted upon later in this report.
4. TPM and Nicotine Deliveries
The gO, El, E2 series show h~Kher ~ and nicotine deliveries due
to the lower efficiency 8Y/35 filters on these samples. However,
domes=it flue-cured (El) delivers more TPM than imported flue-cured (E2)
