Examples of Camel prototypes

Project/prototypeDesign changesEffectsOutcome
Source: industry documents.14, 34, 58–61
ZX (12 mg)Strong tobacco on fire endIncreased strengthMatched Marlboro with increased smoothness at end of cigarette
Smoother tobacco on filter endIncreased smoothness
Reduced differential between endsReduced harshness
CT-790-AExperimental G-7 (without G-9)Increased smoothnessSmoother product but too harsh; recommend further development using prototype as basis
Experimental G-13 (puffed tobacco without top dressing)Increased smoothness
No air dilutionIncreased strength
No denicotinised tobacco (KDN)Increased strength
CT-1559-BLower nicotine burleyIncreased smoothnessImplemented in February 1989 as Camel Lights; rated parity to Marlboro on acceptance
Low nicotine flue cured tobaccoLess harsh, smoother
G-7-4 (new reconstituted sheet)Improved acceptance
Increased humectantIncreased smoothness
New top dressingIncreased smoothness; “Marlboro-Like”
Reduced draft/reduced draw resistanceIncrease strength without harshness
CT-1582 A/DNo burley casingDecreased harshnessPreliminary testing found increased smoothness among 18–20 year olds; manufacturing prototype too harsh, less smooth
Low pack moistureIncreased strength
4% Glystar (Hystar/glycerin)Decreased harshness
K22 (Heat treated burley, no KDN)Decreased harshness
Decreased dilution/ increased draftIncreased tobacco taste
