What are the ingredients in vape oil?


E-cigarette liquid or e-cigarette liquid is water, food grade seasoning, you can choose a mixture of nicotine degree or not, and a mixture of propylene glycol (PG) or vegetable glycerin (VG).

E-cigarette users need to know the substances they inhale, including substances contained in e-cigarette oil.

The active ingredients of e-cigarette oil include:

Propylene Glycol (PG)
Vegetable glycerin (VG)
A mix of PG and VG.
Nicotine (may not contain)
Food grade seasoning

Propylene Glycol (PG)

PG is one of the main components of e-cigarette oil. It is a laboratory-made substance used to add flavor to electronic cigarettes. PG is an alcohol with a light and pleasant taste, although it is not sufficient as a sweetener. It is an odorless, tasteless humectant that can be used to generate solid vapors. In addition, it is used in many products (including medicines and foods) to keep them moist.

The PG in e-cigarette oil can improve the flavor and leave a lingering fragrance on the back of the throat.

It can also be used as an antifreeze. Some people think that e-cigarette oil contains antifreeze, which is a false belief. Because of its versatility, safety, and non-toxicity to household pets and young people, PG is only an ingredient in antifreeze.

PG is used in e-cigarette liquid because it is a thin liquid, so the complexity of filling and refilling the atomizer is reduced. Its slim characteristics make the e-cigarette oil produce much less fouling, and it will not agglomerate on the e-cigarette packaging coil. PG absorbs warmth quickly, which means that once the e-cigarette is activated, you can start e-cigarette faster; therefore, the smoke of e-cigarette does feel warmer.

The allergy risk of PG type e-cigarette oil is extremely small. They can usually breathe or inhale without risk and produce smaller vapors, so your cloud cover will definitely be less common. For a small percentage of individuals who are sensitive to e-liquid with a high percentage of PG, they can switch to individuals with a higher percentage of vegetable glycerin (VG).

Vegetable glycerin (VG)


Like PG, vegetable glycerin (VG) is a non-toxic, colorless and odorless liquid. It has a sweet taste. In addition to PG, you can also tell it because it is thick and very thick, which is why the high VG e-cigarette liquid is also thick for older atomizers. VG is also a sugar component in the food market. Similarly, it is also used in various drugs.

The VG in the e-cigarette liquid produces a large amount of vapor, and is more likely to be produced on the throat; therefore, its taste is less intense. Its sweetness makes the final product sweeter than PG. Its disadvantage is that it will form a rough accumulation on the coil, and it also requires more power to reach the optimal temperature so that it can be used for all e-cigarettes.

In general, vegetable glycerin (VG) is generally considered risk-free. However, like all other products, if you are allergic to VG, VG may not be suitable for you.

PG/VG ratio in vape oil

Now that you know what VG and PG are in e-cigarette oil, you can choose an item with the ideal PG/VG ratio. E-cigarette liquid usually includes a mixture of these two active ingredients. This combination means that you can choose e-cigarette oil with a balance of throat hit, flavor intensity and cloud thickness.

When choosing the best ratio, consider whether you are sensitive to PG. If your evaporator is old or usually miniature, you may want to avoid using high levels of VG. For example, 70% of PG e-juice in conventional e-cigarettes is sufficient to meet the requirements of beginners. The 50/50 mixture of PG and VG is usually used with electronic cigarettes with higher performance and higher resistance to draw. It is best to have clouds and maintain a strong flavor.

If you are not sure about the ratio to determine, choosing a comprehensive e-cigarette liquid will help you find the most suitable taste.



Many e-cigarette liquids consist of nicotine. It is derived from tobacco plants or artificial resources. Nicotine can improve the taste of electronic cigarettes, and can satisfy people’s wishes without using tobacco leaves. Nevertheless, it is usually addictive. When taking large amounts, your mind will definitely force you to crave nicotine when you stop taking nicotine.

Independent research conducted by global public health authorities (such as Public Health England) found that e-cigarettes are at least 95% less harmful than smoking. Cigarette smoke can cause long-term damage such as carcinogenesis. After switching from cigarettes to electronic cigarettes, they must take measures little by little. This method requires the use of reduced nicotine content in the e-liquid within a few months, and finally the use of nicotine-free e-liquid.

The content of the nicotine in the e-cigarette oil varies. The nicotine in e-cigarette oil is determined in milligrams or percentages of quantity. For example, 3 mg of nicotine is the same as 0.3% nicotine. The nicotine content in e-cigarette oil needs to be accurately determined.

The user’s choice is different, the most effective point is that you can also choose not to use nicotine atomization. When you need to take nicotine, you can also use other nicotine substitutes.

Some options include:

0% is very suitable for people who want to get rid of their dependence on nicotine.
0.3% applies to extreme smokers or those who use e-cigarettes for the first time.
0.6% applies to smokers who routinely use ten light cigarettes a day.
1.2% of people smoked 15 regular cigarettes a day.
The high tenacity nicotine content is 1.8%, suitable for people who smoke more than 20 or unfiltered cigarettes a day.

The highest nicotine content in e-cigarette oil is 2.4%, 3.6% and 5%.

Food grade seasoning


When you choose to change the nicotine level, just adjust one level up or down to prevent the signs and symptoms of shock or withdrawal.

Generally, flavors account for 1% to 10% of the total volume of the electronic juice. The benefits of atomization include a variety of flavors. The liquid is a bit appetizing. Therefore, food-grade additives are used to add flavor to it. The taste is very concentrated and it doesn’t cost much. Their dishes and proportions are similar to basic cooking recipes. In order to achieve the best results. They were checked in the laboratory, fine-tuned and mixed correctly.

The source of the seasoning is very important. Some people use the internet to make their own flavors. Spices in grocery stores may contain dangerously inhaled oils. Therefore, we recommend sticking to the taste of e-cigarette suppliers.

However, you cannot fully understand the active ingredients of the taste based on the label. The FDA allows food manufacturers to hide selected proprietary information to maintain the uniqueness of their flavors. Therefore, since they are the best, it is very important to obtain e-cigarette liquid from expert brands only.

How do I PG or VG?

Propylene Glycol Vape Liquid 

PG fluids are generally thinner than VG. This makes it easier for the wax or cotton on the atomizer to absorb the fluid.

Due to the thinner consistency, there are usually much less deposits on tanks and atomizers. This will produce a cleaner e-cigarette experience.

PG e-liquid/liquid has no flavor at all, which means that it will not affect the overall flavor of e-liquid.

It produces a better voice similar to smoking. Several users liked this feeling, so they chose PG e-liquid.

Some people report allergies to PG e-juice or e-cigarette oil.

Vegetable glycerin vape oil/liquid

VG e-cigarette liquid or e-cigarette liquid usually becomes thicker. As a result, it tends to produce more residue and build-up on the evaporator components, and can additionally reduce the life of the atomizer.

VG Electronic Cigarette Liquid or Electronic Cigarette Liquid I like it very much. It is commonly used as a sweetener in sugar substitutes.

VG e-liquid or e-cigarette e-liquid produces a denser vapor cloud due to its total dense composition. This is one of the main advantages of using VG instead of PG.

Compared with PG liquid, when using e-cigarette liquid/liquid, many customers complained of throat discomfort. VG e-liquid tends to produce a smoother impact.

Several people have reported allergies to VG e-liquid or e-liquid. It has been reported that after regular use of VG e-liquid or e-liquid, sputum will accumulate in the throat.

Whether you choose VG or PG, it depends on your personal choice. Want a greater throat hit? PG is the only way. Want to burn a thick vapor cloud? VG is the best choice.

How can I choose vape oil

First of all, choosing a good e-liquid should look at the following aspects:

Look at the color

Without nicotine, e-liquid is generally colorless or light yellow. If you add some heavy-colored extracts, there will be a corresponding color. If it contains nicotine or adds too many natural extracts, the coloring will be more unstable, and it may change color after a day or two or after exposure to sunlight. Fruit color It is more unstable. I think tobacco and mint are generally light yellows or golden yellow.


The first smell should not be unpleasant. You can dislike the smell, but it should not be unpleasant and repellent, except for female compatriots, especially tobacco or nicotine.

Look at the amount of smoke

The amount of smoke is not only related to the quality of the atomizer but also has a lot to do with the e-liquid. I think it would be great if the two are well matched. Relatively speaking, the e-liquid with a large amount of smoke is better than a small one. It is easy to smoke, and the smoke is fine and smooth. The burning smell may be related to the smoke oil, but the atomizer may be higher.

The feeling of passing through the throat

Friends who smoke know the feeling of the throat. In writing, it is the impact on the throat. This is mainly the effect of nicotine. Nicotine-free e-liquid basically has no impact on the throat, but too high nicotine will cause irritation. It feels that most of us can withstand 16MG.

It’s pretty good. If you don’t have a smoking age of 8 or 10 years, you should not choose a high-concentration one.

For our domestic flue-cured cigarettes, the amount of nicotine that is similar to its impact is 6-8MG. If it is foreign heavy-flavored cigarettes, such as Red Marlboro, Camel, American Spirit, etc., it needs to be about 12MG. Foreigners generally have more flavors, haha.

The higher concentration of nicotine in a good e-liquid will not cause too much irritation to the throat, and a bad puff is like being struck by a needle.

Feeling through the lungs and nose

If you can’t even pass the throat level, you can’t pass the lungs and nose. I can’t describe the feeling of passing the lungs in words. Only after passing the nose will you really appreciate the taste of this e-liquid.

In the step of smelling the smell above, what you smell is only the surface smell. The professional name is (table fragrance or top fragrance). In general, a good e-liquid generally feels comfortable, can taste the taste, and can also play a refreshing and refreshing effect.

The feeling of the mouth after inhaling

Many people have responded that the throat will be very dry after smoking the e-cigarette. It is right to be a little dry, and it will heal soon after stopping, because PG and VG have water absorption, but it is not right to be dry. If you smoke too frequently, of course you will feel dry. Chewing gum is delicious. If you eat more in a short time, your teeth will also be sour. You can still feel the smell of this e-liquid within a short time after you stop smoking.


As an e-cigarette user, it is important to understand all the truth about e-cigarette oil. Recognizing what e-cigarette oil is, your preferred nicotine toughness, and the best PG/VG ratio will definitely provide you with the most effective e-cigarette experience.
