E-liquid ingredients are not complicated. “DIY e-liquid” refers to obtaining the various raw materials yourself and blending e-liquid by hand according to a certain recipe or formula. So what is the right ratio for flavor concentrates in DIY e-liquid? China E-Cigarette News explains below.
DIY E-Liquid Guide: What Is the Right Flavor Concentrate Ratio?
8%-15% is a useful reference range. In general, e-liquids made for overseas markets are often mixed at around 10%. More specifically: tobacco flavors 8%, fruit flavors 10%, and menthol flavors 5%.
1. TFA concentrates: fruit flavors are generally considered on the lighter side, so the ratio can be around 10%-15%. Cream flavors are quite full, and 10% is a commonly used ratio.
2. Hellocig concentrates: rich and bold in flavor. Fruit profiles are especially strong and aromatic. About 10% is a typical mixing ratio. If you prefer stronger flavors, you can increase it appropriately.
3. Capella concentrates: overall stronger than TFA concentrates, and also slightly more expensive. Flavor accuracy is high and stability is good. Start testing at 10%, then adjust according to personal preference.
The concentrate ratios provided above are only general guidelines. Since everyone’s sensitivity and preference for flavor intensity differ, you can increase or decrease the amount when mixing your own e-liquid. No one can do this exploration for you—you have to figure it out yourself, and that’s part of the fun of DIY e-liquid.
Hard Rules for DIY E-Liquid — Please Follow Them Strictly
1. Never try to buy pure nicotine. It is highly toxic, and even skin contact can cause harm. Generally speaking, 100mg/ml nicotine solution is already considered the upper concentration limit.
2. Do not let high-concentration nicotine solution come into contact with any part of your body. Be sure to keep this in mind when making DIY e-liquid.
3. When making DIY e-liquid, always wear protective rubber gloves. If possible, also wear work clothes (to prevent high-concentration ingredients from getting on your favorite clothing) and protective goggles.
4. Don’t blindly pursue higher nicotine strength just for a stronger hit. The body absorbs nicotine from vaping devices and traditional cigarettes differently, and it also varies by person. I strongly recommend starting with e-liquid at 12mg/ml nicotine strength, then adjusting gradually downward or upward as needed. Branded e-liquids on the market generally top out at 36mg/ml nicotine, so do not attempt to DIY e-liquid above this strength. Don’t gamble with your personal safety.
5. When making DIY e-liquid, always keep minors and pets away from the area (the same applies to low-strength finished e-liquid).
6. Be mindful of fire hazards when making and storing e-liquid or raw materials. Most finished e-liquids and raw ingredients are flammable.
7. When making DIY e-liquid, place all ingredient bottles securely to avoid splashing or spills caused by accidental contact.
8. If possible, you can buy a nicotine testing device (it looks high-tech, but it’s actually not expensive) to avoid making e-liquid with excessively high nicotine strength due to mixing errors.
9. Be sure to buy internationally recognized e-liquid raw materials that meet safety standards, are clearly labeled as suitable for e-liquid use, and come from major brands (PG, VG, AG, nicotine solution, flavorings, sweeteners, etc.). This issue is also mentioned in Peter’s post, “Choose PG and VG with USP labeling when making your own e-liquid.” Also note that not all food flavorings are suitable for e-liquid. Some may be harmless in liquid form, but could become toxic after turning into vapor or aerosol (this may be covered in a separate post later).
10. If you have been using e-cigarettes for less than three months, DIY e-liquid is not recommended.
11. Some people may be allergic to PG or experience discomfort from it, but this generally does not cause serious health problems.
