cigarettes so manufactured are designated Sample Nos. 

 1, 2, 3 and C-1, corresponding to the sample of filler 

 material from which each cigarette is manufactured. 



The nilsr material employed in providing the tobacco 

 rod is in the form of strands cut at alxjiit 32 cuts per 

 inch. The initial filler material includes a blend of about 

 9 percent Burley tobacco, about 41 percent flue-cured 

 tobacco, about 32 percent reconstituted tobacco mate- 

 rial, and about 18 percent Oriental tobacco. The blend 



the level of l-nicoline levulinale is increased. The vari- 

 ous cigarettes each exhibit shnilar "tar" deliveries, car- 

 bon monoxide deliveries and puff counts. Further, the 

 samples of the invention (i.e . Sample Nos. 1-3) exhibit 

 a pH of the whole smoke lower than that of the sample 

 not having the exogenous nicotine/organic acid sail 

 (i.e.. Sample No. C-l). 



Evaluations of the organoleptic properties of the 

 Sample Nos. 2. 3 and C-l indicate that the cigarette 



has an aqueous casing of glycerin and flavors applied 10 having 5 percent salt additive (i e., Sample No 3) exhib- 



its greater impact and smoothness as well as less harsh- 

 ness than the cigarette not having salt additive (i.e.. 

 Sample No. C-l). Sample No. 2 is not significantly dif- 

 ferent organoleptically from Sample No. C-l in terms (*f 

 harshness and overall taste, even Ihrou^'.. there is a 

 substantial increase in FTC nicotine of the sample rela- 

 tive to the comparative sample Thus, the nicotine levu- 

 linale additive provides for a cigarette having a rela- 

 tively low FTC "tar" to FTC nicotine ratio while hav- 



thcreto. 



Four Ids of the cut filler blend, each lot weighing 

 1,520 g, are provided. The first lot is treated with 20 g 

 of the 1-nicotine levulinatc additive. The second lot is 

 treated with «) g of the 1-nicotiiie levulinatc additive IS 

 The third lot is treated with 100 g of the 1-nicotine 

 levulinale additive. The fourth lot is not treated with 

 the 1-nicotiiie levulinatc additive and is employed for 

 comparison purposes. 



The 1 -nicotine levuliiiate additive is applied to cut 20 ing a smooth (i.e., not overly harsh) taste,

cigarette paper wrap ^ lich is sold commercially as 854 

 Cigarette Paper by Ecusta Corp. The filter element is 

 manufactured using conventional cigarette filter mak- 

 ing technology from cellulose acetate tow (2.1 denier 

 .'.5 per filament. 48,000 total denier) and circumscribing 

 non-air permeable paper plug wrap. The tobacco rod 

 and niter clement are aligned in an abutting, end-to-end 

 relationship and secured together using a non-air per- 

 meable tipping paper. The tipping paper is adhesively 



thereto and is designated as Sample No. 3. The resulting 40 secured to the filler element and the adj.-icenl portion of 



blend provided from the fourth lot of filler material is 

 not treated with the l-nicoline levulinale salt additive, is 

 employed for comparison purposes, and is designated as 

 Sample No C-l.

 length of the filter element ad about 3 mm of the length 

 of the tobacco rod. Cigarettes so described are manu- 

 factured using a Pilot Cigareite Maker from Hauni-

 are provided a mound the periphery of the cigarette

The data in Table I indicate that the various ciga- 05 

 rettcs exhibit increased FTC nicotine vaUies us the level 

 of 1-ntcotine levulinale is increased. In addition, the 

 FTC "tar" to nicotine ratios for the samples decrease as 



pertorated cigarette is 75 percent air diluted. The ciga- 

 rettes so manufactured are designated Sample Nos. 4, 5.
