Anything colder than WS-23?
Leave a message
Yes, several cooling agents are considered stronger or different in effect than WS-23. The most direct and potent alternative is WS-3.
Here is a comparison of cooling agents that are often discussed in the context of strength and sensory effect relative to WS-23:
| Cooling Agent | Reported Relative Strength & Key Characteristics | Sensory Profile |
|---|---|---|
| WS-3 | Generally considered stronger than WS-23. Provides a powerful, immediate cooling sensation. | Can have a more pronounced or "sharp" cooling impact, sometimes accompanied by slight aromatic notes. |
| WS-23 | The baseline for comparison. Provides a smooth, round, and pervasive coolness. | Known for being almost odorless and tasteless, offering pure cooling without bitterness or irritation. |
| Coolant Agent 10 (aka (-)-Menthoxypropanediol) | Cooling intensity can be 20%-100% of menthol, but its duration is much longer (up to 2x that of menthol). In some applications, its cooling strength is reported as 2-2.5 times that of menthol. | Offers a long-lasting, pleasant coolness. The "2S" isomer is significantly stronger than the "2R" form. |
| Frescolat MGA & ML | Frescolat MGA (Menthone Glycerin Acetal) and Frescolat ML (Menthyl Lactate) are recognized for their persistent and pleasant cooling effect. | Menthyl Lactate has a very mild minty taste and is known for its stable, non-irritating coolness. |
🧪 Tips for Finding the Right Cool
Consider Blending: Many manufacturers blend different cooling agents like WS-3 and WS-23 to create a more complex sensation-a sharp initial kick followed by a long-lasting, smooth coolness.
Source from Specialized Suppliers: These chemicals are typically sold as raw materials from chemical or food ingredient companies. Look for suppliers specializing in "flavor concentrates" or "cooling agents" for DIY e-liquid, who may offer these compounds in small, manageable quantities.
