The Regulatory Context
Several markets restrict menthol in cigarettes; e-liquid menthol rules vary by country. Regardless of outcome, cooling-agent blends give formulators a compliant toolset: pure cooling with no mint character, layerable under any flavor profile.
Designing a Menthol-Free Cooling Curve
WS-23 provides fast, clean onset; WS-3 extends duration; WS-12 adds intensity at higher dosages; WS-5 and WS-27 fine-tune the curve. Blending these achieves menthol-like sensation profiles with different regulatory footprints.
Frequently Asked Questions
Can cooling agents fully replace menthol?
For pure cooling sensation, yes – blends of WS agents replicate menthol cooling curves. For mint flavor itself, mint flavor concentrates are still needed.
What blend should I start with?
A common starting point: 60% WS-23, 25% WS-3, 15% WS-12, dosed at 0.5-2% in the final product.
