USE of Paraffin Wax in Tobacco Filler to Give Possible Controlled Profile
Abstract
Relates the procedure for testing of a cigarette coated with a paraffin wax to obtain a controlled-profile cigarette. Says the procedure caused "increased RTD" during smoking and that lack of control over the puff at which an increased RTD occurred caused further work on this approach to be curtailed.

Use of Paraffin Wax
Controlled Profile
tobacco filler was for the following purpose:
The work`done in the past (1967) with wax sprayed on the
To obtain a controlled profile cigaret with wax
in the filler causing increased RTD during
smoking. With filter dilution, possibly a
controlled profile could be obtained.
The wax (Histowax, 56-58°C, M.P.) was dissolved inin-hexane
and sprayed onitobacco filler,; after drying,, rods were formed
and equilibrated.
A puff-by-puff analysis'of RTD versus percent dilution during
smoking,indicated that l-2% wax was found to give increased
RTD,during smoking on the 6th puff or later. Greater than 2%
wax concentration caused'sharp RTD increase on about the 3'rd
puff. All increased in RTD were sharp, not gradual.
With l-2% wax, we obtained increased RTD in some cases - in,
others none. In some instances we hadincreased RTD, then a
decrease and finally an increase in RTD again. We could not
control the puff at which an increased RTD occurred. Primarily
this lack of control over increasing RTD during smoking curtailed'
further work with this approach for a controlled profile.
