What is E Liquid

The most important thing to say about e-cigarettes is definitely e-liquid. No matter how powerful the atomizer is, it needs an e-liquid comparable to it. First, there are five main components in e liquid vape juice. Vegetable glycerin (VG) What is vegetable glycerin? The vegetable glycerin in e-cigarettes is generally extracted from plant materials. It is not just the e-liquid component used in e-cigarettes. It is also used for food, cosmetics and medicines, the ones we eat Chocolate cake contains a lot of vegetable glycerin, which can be eaten directly. In the introduction to toxicology, it also shows that vegetable glycerin is non-toxic. After eating, it is directly digested and then becomes a source of nutrients we need daily. The main function of glycerin in e-liquid is to increase the amount of smoke that the e-liquid can produce, and the higher the proportion of glycerin in the e-liquid, the denser the mist produced after heating. If you want to spit out large amounts of smoke, you can use pure 100% glycerin directly. Except for the original sweetness of glycerin, there will be no other taste in the e-liquid. The smoke is very large. But pure glycerin has very poor circulation in cotton, and it is not easy to conduct oil. If you use an oil storage atomizer to pump 100% glycerin, it is difficult for cotton to conduct oil in time, which will lead to a few mouthfuls Paste the core directly. Propylene Glycol (PG) Propylene glycol can basically be defined as a colorless and odorless liquid with very good circulation. The toxicity and irritation are relatively low. Generally, the amount of e-cigarette liquid used will not cause any problems. However, it should be noted that propylene glycol is allergic to some friends, and some small bumps will appear on the skin. At the same time, it is a little irritating to the throat. Healthy players will not think that there is a problem, but if you are born with laryngitis or throat Friends in question, when using a high concentration of PG e-liquid, such as 50%PG\50%VG, you will have a cough or discomfort. Just choose a higher VG content e-liquid, such as 30% PG\70%VG or 20%PG\80%VG, the lower the ratio of PG, the corresponding throat hit will be much less, and the throat irritation will be much less. 　　The role of propylene glycol in e-liquid is mainly to increase the degree of blending of flavors, and the other is to provide a little smoke. Because of its structure, vegetable glycerin is difficult to carry the flavor, and the flavor is difficult to mix in pure VG, and the e-liquid will be unevenly mixed. In particular, the circulation of VG is also related to the surrounding temperature. In winter, as long as the temperature is lower and the VG content is higher, the flavor and nicotine in the e-liquid will precipitate and float on the surface of the e-liquid. This is a normal phenomenon. Heat the e-liquid with the palm of your hand, shake the bottle and shake the brown nicotine and essence. Therefore, PG is indispensable in e-liquid. Without PG, pure nicotine and flavor are too difficult to dissolve in e-liquid. Nicotine Nicotine is easy to understand. It is nicotine that makes smokers addicted to cigarettes, and it makes us addicted to absorb the carbon monoxide tar and other harmful substances in cigarettes in disguise. It is impossible to determine whether it is harmful or harmless, and even patients who treat depression will have nicotine treatment. Therefore, in cigarettes, it is not nicotine that is really harmful, but the temptation of nicotine to us, which leads to smoking other substances. Of course, even if something like nicotine is in e-liquid, don't mix up high nicotine doses yourself! This is very important, don't buy nicotine solution and add it by yourself! Please do not! Harmful and harmless are just based on normal use, don't challenge those tens of milligrams of e-liquid, that is messy! On the contrary, during normal use, the concentration of nicotine is gradually reduced. I really feel that the zero mg of e-liquid is too boring, smoking 3 mg is enough! The role of nicotine in e-liquid is to increase the throat hit, provide the sensation of smoking a real cigarette, and a slight excitement. Don't reject these feelings of excitement and think that this is passive acceptance. After all, some vegetables such as tomatoes we eat every day contain nicotine. Essence Fragrance is really too much, it is simply the taste of e liquid vape juice. There are two main sources of flavor, one is plant extraction and the other is industrial synthesis. As long as it is a regular manufacturer, the flavors used are reliable. As long as the flavors meet the standards, the problem is not big. Additives Additives are not the same as flavors. Searching for e liquid vape juice additives on the Internet can find out a lot of throat agents, cooling agents, 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 with normal use. But some unscrupulous merchants like to use many illegal additives. The main function of this substance is to increase the flavor of tobacco, which is generally found 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 to the safety of e-liquid.
