e-liquid composition analysis
I have said many times about the composition of e-liquid. E-liquid is composed of PG, VG, and flavor. In addition to the three necessary costs, e-liquid generally includes nicotine and other Food additives. Today we will divide these ingredients in detail.
1. PG, also known as propylene glycol, is a common drug and food additive. It is hygroscopic and hygroscopic, slightly sweet, colorless, odorless and transparent liquid with good fluidity. The US Food and Drug Administration (FDA) defines PG as "generally safe for humans." Of course, there is also a saying that PG is slightly poisonous. PG, as one of the basic ingredients of e-liquid, is mainly used as a carrier of flavors to enhance the taste of e-liquid. After heating, it will generate a small amount of mist with a certain throat hit. Diluted VG also reduces e-liquid viscosity and facilitates oil transfer.
Although PG is generally safe for the human body, a small number of people still have side effects such as throat discomfort, sputum, and allergies. These side effects are short-lived and mild. As long as you stop smoking or change e-liquid with low PG content or e-liquid without PG, the symptoms will naturally disappear. Generally speaking, e-liquid with a high PG content has a thicker taste, a slightly stronger throat hit, and a relatively small amount of smoke.
2, VG, also called vegetable glycerin or glycerol. Like PG, it is also a widely used raw material in daily life. Attentive friends look at the cosmetics, food, wine, sugar around them, the ingredients marked on these packages have "propylene glycol, glycerol". People who especially like to eat sweets also consume a lot of VG. Because cakes, biscuits and other sweet ingredients, most of them contain VG. The main role of VG in e-liquid is to produce mist.
VG will generate a large amount of mist after heating. Generally, friends who use too much smoke or oil drop atomizers should know that if you want to increase the amount of smoke, you need to use product oil to add a large amount of VG to generate the ideal smoke. VG is highly hygroscopic and very sticky. If an e-liquid has poor fluidity, it must be a high VG ratio. Such e-liquid smoke is very large, the flavor is slightly worse, and the throat hit is slightly weaker.
3, flavor, the role of essence in e-liquid is very important, it can be said that the soul of e-liquid. The flavor of e-liquid is determined by the flavor. The combination of different flavors and flavors determines the flavor of an e-liquid. The e-liquid with a unique flavor in general has a very complicated flavor formula. Some special flavors, such as "mint", also have Throat hits.
4. The main role of nicotine is to relieve smoking addiction and produce Throat hit. And has a certain effect to enhance the taste of e-liquid. Some people talk about "the nicotine discoloration" and think that nicotine is highly toxic. In fact, e-liquid contains nicotine solution, and the concentration is not high. Nicotine, which has been closely linked to "death" and "cancer" for nearly a century, has now received a lot of new attention, and many experts have justified its name. It is believed that the nicotine in cigarettes does not cause too much harm. The real carcinogens are tar, carbon monoxide and the burning of more than 4,000 kinds of poisonous, harmful and even radioactive substances.
Of course, the harmful effects of nicotine on the body cannot be ignored. Therefore, it is best to gradually reduce the nicotine concentration of e-liquid and quit nicotine dependence as soon as possible. e-liquid Nicotine concentration is usually 0mg, 6mg, 12mg, 18mg. The higher the number, the higher the nicotine concentration per milliliter of e-liquid, and the stronger the throat hit. Of course, the entrance is getting worse. Concentrations that are too high can cause a cough, but also cause stomach pain and dizziness. So if you use the vape again, if the above phenomenon occurs, please replace the e-liquid with low nicotine concentration. Most people use 6mg of e-liquid to feel the best, to meet their needs, Throat hit is good, but not stingy.
5. Additives include sweeteners, sour agents, throat emollients, deionized water (distilled water), etc. The main effect is to improve the taste of e-liquid and make up for the lack of flavor. For example, some flavors of e-liquid will be slightly bitter and sour. You can add sweeteners to improve the taste. The role of deionized water is mainly to dilute VG. Some e-liquids are PG-free, and VG is very viscous, which can lead to poor oil conductance for some oil storage atomizers. In order to maintain the ratio of pure VG, deionized water is added to dilute VG and improve fluidity. Pure water, mineral water, and ordinary tap water are prohibited from being added to e-liquid. Because these water contain ions, and the ions are conductive, if they are added to the e-liquid and then into the atomizer, a short circuit will occur and the equipment will not work, while the deionized water and distilled water are not conductive.
The above is the composition of e-liquid. The raw materials used for good quality e-liquid should be food-grade, that is, they can be used as food raw materials. Some imported or domestically exported e-liquid must also pass the US FDA certification to prove that it is harmless to the human body. Is allowed to sell. Therefore, when choosing e-liquid, try to choose a big brand and a merchant with high integrity. Some unknown e-liquids are best not to try. It is likely that the "black workshop" was blended with unqualified and inferior raw materials, which is neither sanitary nor harmful to the body.
Through the above explanation, I believe that everyone has already understood the basic ingredients of e-liquid. The qualified e-liquids produced by regular manufacturers say that food-grade raw materials are made, which is very hygienic and safe. These common ingredients that make up e-liquid have already penetrated into our lives. Women's cosmetics and lipsticks all contain PG, VG and fragrance. Cakes, biscuits, and various foods are also included. After you have figured out the ingredients of e-liquid, you don't have to worry too much about whether the ingredients of e-liquid are poisonous and harmful. And when you buy e-liquid in the future, you can choose the appropriate e-liquid according to your needs, and you won't buy by mistake The awkward scene of the high smoke VG e-liquid used in the oil storage atomizer.
