Cooling Agent flavor concentrate - 15 ml

Hello! The "coolant flavor concentrate" you mentioned is usually a food-grade/smoke oil-grade additive used to blend e-cigarette oil. Its main function is to provide a distinctive cool and refreshing taste, rather than being literally a "coolant".
The following is the detailed description of this concentrated liquid:
What is it?
Function: It provides a strong cool sensation, similar to the refreshing coolness of mint, but usually more intense and pure, without any obvious mint flavor. This effect comes from additive WS-23 or Koolada (a cooling agent), which are recognized as safe food additives.
Usage: Primarily used for DIY e-cigarette oil. It can be mixed with other flavor concentrates (such as fruit or dessert flavors) to enhance the complexity and refreshing quality of the taste.
Specification: 15 milliliters is the common entry-level size or the size suitable for small-scale mixing.

2. Main features and effects
Extremely strong cooling sensation: Just adding a small amount (usually 0.5% - 2%) can cause a noticeable cooling effect from the throat to the lungs in the e-liquid.
Almost flavorless: The high-quality coolant concentrate itself has no strong taste, so it will not interfere with the main flavor (such as strawberry, watermelon, etc.), only providing a taste sensation.
Enhance taste: By adding a coolant to overly sweet or rich recipes, they can be made refreshing and not overly thick.
3. How to use?
Important reminder: Mixing the e-liquid by yourself requires certain knowledge and skills. Please operate with caution.
Required tools: sterile syringe, dropper, empty cigarette oil bottle, electronic scale (preferably accurate to 0.01 grams), base solution (PG/VG), nicotine (if needed), and other flavor concentrates.
Determining the ratio: The addition ratio of the coolant concentrate is extremely crucial. An excessive amount will result in an overly cold temperature and even cause a stinging sensation.
Recommended starting ratio: 0.5% - 1.5% (as a percentage of the total volume of the e-liquid).
For example: Mix 30 milliliters of e-liquid, add 1% coolant, that is, 30ml * 1% = 0.3ml.
Mixing steps:
Suction in the syringe the concentrated coolant solution of the calculated amount.
Inject the empty e-cigarette oil bottle.
Then add other flavor concentrates, base liquid and nicotine.
Seal the bottle cap tightly and shake it thoroughly to mix evenly.
Oil removal: Leave it for a period of time (from a few hours to several days) to allow all the components to fully blend. The texture will become more stable.
4. Important Notes
Do not use directly: Never consume the concentrated solution alone! It must be diluted extensively before it can be used.
Start with a small proportion: Since people's tolerance for coolness varies, it is recommended to start with the lowest proportion (such as 0.5%) and then adjust according to personal preference.
Skin contact: Avoid direct contact of the concentrated solution with the skin, especially sensitive areas. This may cause a brief sensation of cold irritation. In case of accidental contact, rinse with clean water.
Storage: Store in a dark and cool place.
5. Besides blending the e-liquid, are there any other uses?
Theoretically, since it is a food-grade additive, it can also be used in very small amounts to be added to homemade beverages or desserts to create a cool taste (such as smoothies, cocktails). But please note:

Extremely low dosage: The amount used for food additives needs to be extremely small, and there is no unified standard, which poses risks.
Safety disclaimer: This is not its primary use. If you are not a professional, it is not recommended that you attempt it.
In summary, the 15ml cooling agent flavor concentrate bottle in your hand is a powerful tool for DIY e-liquid enthusiasts to enhance the icy-cold taste. When using it, be cautious and start with a low concentration, and ensure thorough dilution.
