REPORT ON: | Analysis of Cigarette Filter and Acetate Tow Samples for Silicon |
REPORT FOR: | John Player & Sons

PO#: | TR-45876 |
DATE: | September 8, 1994 |
We have tested the samples obtained during the months of July and August
1994 and report as follows:
OBJECTIVE:
A study was undertaken for John Player & Son’s on the filters of
cigarettes, of brands made in Canada to be analyzed for the presence of
fiberglass. As the main component of fiberglass would be silicon (Si),
it was determined by the undersigned that the identification of silicon
in appreciable amounts would indicate fiberglass contamination in the filters
and the raw acetate tow used in the manufacturing of the cigarette filter
for the presence of silicon.
SAMPLE PROCUREMENT AND METHODS OF TESTING:
Samples of Canadian cigarette brands were purchased by Can Test Ltd. from retail outlets in the Vancouver area during the months of July and August 1994.
Of the 147 brands made in Canada, 101 brands were obtained in this way,
which make up a 94% share of the Canadian market. Samples of the remaining
46 brands were obtained from other regions of Canada. Samples of cellulose
acetate tows were provided by the two major suppliers to the Canadian cigarette
industry -- Celanese Canada Inc. and Eastmanchem Inc.
METHOD OF TESTING:
In order to obtain some statistical data from the analysis, it was suggested
that a minimum of three separate filters from each specific brand of cigarette
be used in the analysis. Also that each sample be analyzed in triplicate
(i.e. three different packages analyzed to produce three separate results).
CONCLUSION:
For filter cigarette brands having only cellulose acetate as filter material, there was no detectable silicon concentration found and therefore, it can be concluded that there is no fiberglass contamination.
