Examples of Camel prototypes
| Project/prototype | Design changes | Effects | Outcome |
|---|---|---|---|
| Source: industry documents.14, 34, 58–61 | |||
| ZX (12 mg) | Strong tobacco on fire end | Increased strength | Matched Marlboro with increased smoothness at end of cigarette |
| Smoother tobacco on filter end | Increased smoothness | ||
| Reduced differential between ends | Reduced harshness | ||
| CT-790-A | Experimental G-7 (without G-9) | Increased smoothness | Smoother product but too harsh; recommend further development using prototype as basis |
| Experimental G-13 (puffed tobacco without top dressing) | Increased smoothness | ||
| No air dilution | Increased strength | ||
| No denicotinised tobacco (KDN) | Increased strength | ||
| CT-1559-B | Lower nicotine burley | Increased smoothness | Implemented in February 1989 as Camel Lights; rated parity to Marlboro on acceptance |
| Low nicotine flue cured tobacco | Less harsh, smoother | ||
| G-7-4 (new reconstituted sheet) | Improved acceptance | ||
| Increased humectant | Increased smoothness | ||
| New top dressing | Increased smoothness; “Marlboro-Like” | ||
| Reduced draft/reduced draw resistance | Increase strength without harshness | ||
| CT-1582 A/D | No burley casing | Decreased harshness | Preliminary testing found increased smoothness among 18–20 year olds; manufacturing prototype too harsh, less smooth |
| Low pack moisture | Increased strength | ||
| 4% Glystar (Hystar/glycerin) | Decreased harshness | ||
| K22 (Heat treated burley, no KDN) | Decreased harshness | ||
| Decreased dilution/ increased draft | Increased tobacco taste | ||
