What is the composition of e-cigarette liquid?

The most important thing to say in electronic cigarettes is definitely e-liquid. No matter how powerful the atomizer is, it needs an e-liquid to match it. First of all, there are five main components in e-liquid, let's take them one by one.

Vegetable glycerin (VG, glycerol, natural glycerin)

What is vegetable glycerin? Vegetable glycerin in electronic cigarettes is generally extracted from plant materials, not only the e-liquid components used in electronic cigarettes, but also used as food, cosmetics and medicines. Those we eat Chocolate cakes contain a lot of vegetable glycerin, which can be eaten directly. In the introduction of toxicology, it is also stated that vegetable glycerin is non-toxic, and after eating it, it is directly digested and then becomes the source of nutrition we need every day.

The main function of glycerin in e-juice is to increase the amount of smoke that can be produced by e-juice, and the higher the proportion of glycerin in e-juice, the denser the mist generated after heating. If you want to spit out a big smoke, you can use pure 100% glycerin directly. In addition to the sweetness that comes with the original ecology of glycerin, there will be no other taste in the e-liquid. The smoke is very large. However, pure glycerin has very poor circulation in cotton, so it is commonly known that it is not easy to guide oil. If you use an oil storage atomizer to pump 100% glycerin, it will be difficult for cotton to guide oil in time, which will lead to after a few puffs. Straight to the core.

What is the composition of the e-liquid of electronic cigarettes, is it harmful to the human body?

Propylene Glycol (PG)

Propylene glycol can basically be defined as a colorless and odorless liquid with very good fluidity. The toxicity and irritation are relatively small. Generally, the amount of e-cigarette oil used will not cause any problems. However, it should be noted that propylene glycol has allergic reactions to some friends, and some small bumps will appear on the skin. At the same time, it is irritating to the throat. Healthy players will not feel a problem, but if you are born with laryngitis or sore throat For those who have problems, when using a very high concentration of PG e-juice, such as 50% PG \ 50% VG, there will be a cough or discomfort. Just choose e-juice with a higher VG content, such as 30%. PG\70%VG or 20%PG\80%VG, the lower the ratio of PG, the corresponding throat hit feeling will be much less, and the stimulation to the throat will be much less.

The main function of propylene glycol in e-liquid is to increase the degree of mixing of flavors, and the second is to provide some amount of smoke. Because of its structure, vegetable glycerin is difficult to carry the essence, and it is difficult to mix the essence in pure VG, resulting in uneven mixing of e-liquid. In particular, the fluidity of VG is also related to the surrounding temperature. As long as the temperature is lower in winter, the essence and nicotine in the e-juice with relatively high VG content will be precipitated and float on the surface of the e-juice. This is a normal phenomenon, heat the e-juice with the palm of your hand and shake the bottle to re-shake the brown nicotine and flavor. Therefore, PG is indispensable in e-liquid. Without PG, pure nicotine and flavor are too insoluble in e-liquid.

Nicotine (nicotine)

Nicotine is easy to understand. It is nicotine that makes smokers addicted to cigarettes, and it makes us addicted to absorb thousands of harmful substances such as carbon monoxide tar in cigarettes in disguise. In itself, it is impossible to determine whether it is harmful or harmless, and even patients who are treated for depression have nicotine treatments. So in cigarettes, it is not nicotine that is really harmful, but because of the temptation of nicotine to us, other substances are smoked along the way. Of course, even if something like nicotine is in e-juice, don't mix up high nicotine doses by yourself! ! ! This is very important, don't kill yourself, don't buy a nicotine solution and add it yourself! Please do not! no Zuo no Die! Don't fuck for a throat hit! Harmful and harmless are only based on normal use, and people will die if they drink too much water! Not to mention nicotine, don't challenge those e-liquids with dozens of milligrams, that's a mess! On the contrary, in normal use, the concentration of nicotine is gradually reduced. I really feel that 0 mg of e-juice is too boring, and 3 mg of e-juice is enough. As long as you do not hold the bottle and blow it all day, it is not a big problem! At most, the body tells you that you are a little dizzy, just drink more water after a wave!

The effect of nicotine in e-liquid is to increase the throat hit, provide the feeling of smoking real cigarettes, and a slight excitement. Don't reject these exciting feelings as passive acceptance, after all, some vegetables we eat every day, such as tomatoes, contain nicotine.

Essence

There are really too many flavors. Simply put, it is the taste of e-liquid. There are two main sources of essence, one is plant extraction and the other is industrial synthesis. As long as it is a serious manufacturer, the flavors used are reliable, and don’t think that foreign e-liquids are so powerful and the materials are so good. As long as it is used with flavors that meet national standards, it is not a big problem. The "drinks" we drink every day are not all flavored, except that they are not nutritious, they will not "harm people".

Additives

Additives and flavors are not the same. You can find a lot of e-liquid additives on the Internet, such as throat lozenges, cooling agents, sweeteners, sweeteners, deionized water, etc. These things are the combination of flavors and flavors. The key to the perfect integration of VG and PG is that there is no problem in normal use. But some unscrupulous merchants like to use a lot of illegal additives, such as "butanedione", which has been searched on the Internet. Many e-liquids have been detected in the past, including so-called foreign e-liquids. Dachang, this is why some friends smoked an e-liquid that was very fragrant at first, but became less and less fragrant later, because they were subject to legal or other factors and gradually removed these bad additives. That's it. The main function of this substance is to increase the aroma of tobacco, which generally appears in nuts, flue-cured tobacco and other similar e-liquids. Fruit-flavored e-liquids generally do not contain such additives. There are many similar harmful substances, so compared with the previous four ingredients, the uncertainty of additives is the biggest hidden danger in the safety of e-liquid.
