How to Judge the Quality of E-liquid?

E-liquid, also known as vape juice, is the atomized liquid used with vaping devices. When heated by an e-cigarette atomizer, it produces vapor similar to cigarette smoke. The main ingredients in e-liquid are food-grade or pharmaceutical-grade glycerin, propylene glycol, polyethylene glycol, and tobacco-specific flavorings. Some e-liquids also contain nicotine, mainly to make the taste closer to that of cigarettes. If you want to judge the quality of e-liquid, you can look at the following 4 aspects!
 
1. E-liquid ingredients

1. VG (Vegetable Glycerin)

2. PG (Propylene Glycol)

3. Flavorings

4. Nicotine

VG is a common pharmaceutical and food additive, widely used in cakes, chocolate, and other sweets. It is colorless, odorless, and generally has no significant side effects on the human body.

PG is used to dilute the viscosity of VG. It is also a common pharmaceutical and food additive and is generally considered safe for the human body.

Flavorings are the key factor that gives e-liquid its wide variety of tastes, bringing vapers all kinds of flavor satisfaction. Many foods we consume daily also contain flavorings.

It is not hard to see that these three ingredients are not inherently highly hazardous. They are often used in foods and everyday products. Even children’s toothpaste may contain these ingredients, and some toothpaste labels state that swallowing it is safe.

2. What determines e-liquid quality

The quality of e-liquid is related to three aspects: the solvents should be food-grade or pharmaceutical-grade, the nicotine should ideally be above 98% purity and preferably 99%, and the flavorings should be high-quality flavorings suitable for e-cigarettes.

3. How to judge whether e-liquid is good or bad

1. Look: observe the appearance of the e-liquid. Good e-liquid is usually clear and transparent, with colors such as colorless, light yellow, golden yellow, orange-red, or green. It should look clean and pleasing to the eye.

2. Smell: carefully smell the aroma of the e-liquid. Good e-liquid has a light, full, and attractive aroma with a pleasant lingering scent.

3. Vape: this is the most important step. You must evaluate the e-liquid through actual use. Good e-liquid has a comfortable and full aroma, somewhat similar to tobacco fragrance, provides a satisfying sensation, feels clean on the palate, and is not harsh, spicy, or choking. After use, the lingering aroma remains pleasant.

4. Never buy unbranded or non-compliant e-liquid

Unbranded, non-compliant, and DIY e-liquids can be harmful. There is no need to say much about unbranded products—if they are already “three-no” products, how good can they really be? Since you have already entered the world of vaping devices, there is no need to save face by using cheap low-quality oil. After all, this is not something to show off with. In addition, those who know a little about e-cigarettes may have noticed that there are many so-called “experts” on the market who think they are advanced players, so they start making DIY e-liquid.

In fact, the temperature requirements during the atomization process are very strict, and the flavorings must comply with regulations for tobacco-use flavorings. Only compliant flavorings can be used. These tobacco-derived ingredients are not something everyone can simply buy with money… In addition, nicotine dosage is also strictly controlled, and nicotine solutions with different concentrations have different chemical properties. So never try to make DIY e-liquid yourself.
