(DIY E-Liquid is risky. It is recommended to fully understand the DIY methods and tools before operating. If someone learns from and imitates the occurrence of personal injury accidents, he is responsible for it)

Regarding the DIY of E-Liquid, the original intention of the players is probably these three points:

•  First of all, you can make a unique E-Liquid completely according to your own preferences, which is convenient for finding the one you like the most.
•  Secondly, no matter what grade of raw material is used, the cost of "DIY E-Liquid" is very cost-effective.
•  Finally, through "DIY E-Liquid", you can know more clearly what you are inhaling into your lungs, and you can use it more at ease and be responsible for your health.

So, what are the ingredients and functions of E-Liquid?

E-Liquid is mainly composed of four substances: "trace nicotine", "propylene glycol (PG: Propylene Glycol)", "vegetable glycerin (VG: Vegetable Glycerin)", and "flavoring agent & flavor". People’s favorite ration.

Vegetable glycerin (VG) is a common medicine and food additive (commonly used to make cakes, chocolates and other sweets). It is very hygroscopic, has a greater sweetness than PG, is odorless, colorless and transparent, and has a fluidity similar to edible oil. VG, as one of the essential ingredients of e-liquid (carrying nicotine, flavoring & flavor), is mainly used to produce "a lot of mist. VG has no side effects on the human body, but due to its viscous nature, it will slightly increase the atomizer Difficulty in cleaning. If you see a certain oil that is relatively viscous, it means that the VG content is high.

Propylene glycol (PG) is a common drug and food additive. It is hygroscopic, slightly sweet, odorless, colorless and transparent, and its fluidity is similar to water. The US Food and Drug Administration describes PG as "generally safe for humans." PG, as one of the essential ingredients of e-liquid (carrying nicotine, flavoring & flavor), is mainly used to "carry most of the flavor of e-liquid" and produce "a small amount of mist" and "throat stimulation". If you like "big smoke", the PG content of the e-liquid you choose cannot be too high. Although PG is generally safe for the human body, a small number of people still have side effects such as dry throat, phlegm, and allergies. Such side effects are short-lived and mild, as long as you stop smoking or change to e-liquid with a lower PG content, it will be fine.

Flavors & essences, various flavors of e-liquid are all tuned out through flavors. Flavors and flavors are easier to attach to PG (relatively speaking), but it is worth noting that: the higher the concentration of nicotine in E-Liquid, the less noticeable the flavors and flavors are by the nose and mouth. Some flavors and flavors can also produce "throat stimulation", such as mint flavor.

The amount of flavor used is also very important. For most flavors, only 5% to 20% needs to be added (for some tobacco flavors, only 1% to 3% is needed). When multiple spices need to be mixed, the total amount does not change.

It is usually recommended for novices to start with a small concentration of spices and slowly increase the concentration of spices to find the flavor they like. Similarly, it is recommended to make a small amount of e-liquid first, and then consider making a large amount when you find a favorite formula.

Allocation teaching (proportion of dosage):

The materials should be flavors with UPS food grade, high temperature resistance and water solubility. If the flavor is only resistant to room temperature or contains oil or sugar, it is not suitable for the blending of e-liquid. Novices who make e-liquid by themselves must be very careful about handling nicotine. Never use pure nicotine directly. The consequences are very serious. Wear gloves for operation. If you touch it, you must clean it immediately. Do not use high-purity nicotine solution, about 36mg/ml base solution will do. Mg means nicotine content, don't confuse“%” with “mg”.
