How to make very cold/freezing salt nic?
Leave a message
Of course. Making e-liquid feel "very cold" or "freezing" involves using synthetic cooling agents. It's a straightforward process, but it requires precision and caution, especially when working with concentrated nicotine.
Important Safety Warning: Handling concentrated nicotine (nicotine salts or freebase) is extremely dangerous. It is a potent neurotoxin that can be fatal if absorbed through the skin. You must wear gloves, eye protection, and long sleeves and work in a clean, well-ventilated area.
The "cold" sensation is achieved by adding cooling agents to your e-liquid. The most common and effective one is WS-23.
The Key Ingredient: WS-23
What it is: A synthetic cooling agent. It is odorless and nearly tasteless, providing a pure, physical cooling sensation in the mouth and throat without a minty flavor.
How to buy it: It's typically sold as a concentrated solution, often 10-30% WS-23 dissolved in Propylene Glycol (PG). This is much easier and safer to use than the pure powder.
Step-by-Step Guide to Making "Freezing" Salt Nic E-Liquid
Here is the standard DIY e-liquid mixing process, with the specific step for adding cooling.
What You'll Need:
Nicotine Salts Base (e.g., 50mg/mL in PG/VG)
PG (Propylene Glycol) and VG (Vegetable Glycerin)
Flavor Concentrates of your choice
WS-23 Cooling Agent (e.g., a 30% PG solution)
Digital Scale (accurate to 0.01g) - This is the preferred method for accuracy.
Empty E-Liquid Bottles (60mL or 120mL are common)
Gloves and Safety Glasses
Step 1: Plan Your Recipe
You need a target recipe. Let's create a simple one for a 30mL bottle of 25mg/mL salt nic liquid with a "freezing" cold hit.
Target: 30mL of e-liquid at 25mg/mL nicotine strength.
Cooling Level: For "very cold," we'll use a high percentage of WS-23. A common starting point for a strong coolness is 1-1.5%. For "freezing," you can go up to 2-2.5%. Do not exceed 3%, as it can become unpleasantly harsh and numbing.
Example Recipe by Weight (using a 30% WS-23 Solution):
Nicotine Salt Base (50mg/mL in PG): 15.0g (This brings us to 25mg/mL final strength)
Flavor Concentrates (e.g., Fruit Mix): 3.0g (10% total flavor)
WS-23 (30% Solution): 0.6g (This is 2% of the total mix - a "freezing" level)
PG: 3.4g (to balance the PG/VG ratio)
VG: 18.0g (for a 60% VG final ratio)
TOTAL: 40.0g (which is approximately 30mL)
Step 2: Mix the Components
Weigh Your Bottle: Place your empty bottle on the scale and press "Tare" to zero it out.
Add Nicotine Base: Carefully pour in 15.0g of your nicotine salt base. Tare the scale.
Add Flavors: Add your 3.0g of flavor concentrates. Tare the scale.
Add the Cooling Agent: This is the crucial step. Precisely add 0.6g of the 30% WS-23 solution. Tare the scale.
Add PG/VG: Add the remaining PG and VG to reach your final weight of 40.0g.
Cap and Shake: Secure the cap tightly and shake the bottle vigorously for 1-2 minutes.
Step 3: Steep and Test
Steeping: While some fruit flavors are good "shake and vape," the cooling sensation can change slightly. Let the bottle sit for 24-48 hours for the ingredients to fully bind.
TEST CAUTIOUSLY: After steeping, test your e-liquid. The cold hit will be very strong at 2%. If it's too much, you can dilute the batch by adding more base liquid without cooling agent.
Pro Tips and Troubleshooting
| Situation | Solution |
|---|---|
| Not cold enough? | You can add more WS-23 drop by drop (record how much you add!). Next time, increase the WS-23 percentage in your recipe. |
| Too cold/numbing? | Dilute the batch by mixing it with an equal amount of the same e-liquid without cooling agent. |
| Want a different type of cool? | You can blend WS-23 with other agents like Koolada (WS-3) or Menthol. Koolada provides a "wet" coolness, while menthol adds a minty flavor with coolness. |
| Always mix by weight. | Using syringes for nicotine and concentrates is messy and inaccurate. A $25 digital scale is the most important tool for DIY mixing. |
By following these steps and starting with the 2% WS-23 recommendation, you will create a salt nicotine e-liquid with an intensely cold, freezing sensation. Remember to always prioritize safety when handling nicotine.
