Adding cooling agents like WS-23 to existing e-liquid requires careful dosage calculation to achieve the perfect cooling sensation without overwhelming the flavor. This guide provides practical recommendations for both DIY mixers and commercial manufacturers.
What is WS-23 and Why Add It?
WS-23 is a synthetic cooling agent that provides a clean, intense cooling sensation without any minty taste or odor. Unlike menthol, WS-23 does not alter the flavor profile of your e-liquid. It delivers a cold sensation similar to menthol but purely as a temperature sensation — the cold you get from mint, without the mint taste.
Recommended WS-23 Dosage
The key principle when adding WS-23 is: start low and adjust gradually. It is always easier to add more cooling than to dilute an over-cooled mixture.
For Beginners:
- Start with 0.5% WS-23 in your existing e-liquid for a subtle, pleasant cooling note.
- Test and evaluate — wait 10 minutes for the flavor to settle.
- If more cooling is desired, add 0.25% more and test again.
- Most users find 1-2% total WS-23 to be the sweet spot.
For Commercial Formulations:
| Effect | Dosage | Description |
|---|---|---|
| Subtle | 0.3-0.5% | Light refreshing coolness |
| Moderate | 0.5-1.0% | Clear cooling, flavor unaffected |
| Strong | 1.0-2.0% | Intense cold, for menthol lovers |
| Extreme | 2.0-3.0% | Maximum cooling, may mask flavors |
WS-23 Preparation: Making a 30% PG Solution
- Weigh 30g of WS-23 powder and add to 70g of USP-grade propylene glycol
- Warm to 40-50 degrees Celsius and stir until completely dissolved
- Allow to cool — the solution should remain clear at room temperature
- Store in a sealed container away from direct sunlight
When using this 30% solution, add to e-liquid at 2-3% for the same effect as 0.6-0.9% pure WS-23 powder.
Blending WS-23 with Other Cooling Agents
- WS-23 + WS-3 (3:1): Front-of-mouth burst + throat cooling
- WS-23 + WS-12 (2:1): Intense initial cool + extended duration
- WS-23 + menthol (4:1): Clean cold + mint flavor
Tips for Best Results
- Always steep e-liquid 24-48 hours after adding WS-23 for optimal flavor integration
- WS-23 does not affect nicotine strength — both can be used together
- WS-23 is heat-stable — survives the vaping process without degradation
- Keep your WS-23 PG solution tightly sealed to prevent moisture absorption
