Components of e-liquid: E-liquid is mainly composed of four substances: "milligrams of nicotine", "propylene glycol", "vegetable glycerin", and "flavors".
Trace nicotine:
Also known as nicotine, it is an addictive substance from cigarettes. Adding a small amount of nicotine to e-liquid can ensure that smoking cravings are sufficiently satisfied. Pure nicotine is highly toxic, and the nicotine content in e-liquid is expressed by XXmg/ml. When purchasing e-liquid, smokers can choose 24mg/ml (very high concentration), 18mg/ml (high concentration), 11mg/ml (medium concentration), 8mg/ml (low concentration) or 0mg/ml (no nicotine) . Nicotine with more than 24mg/ml is relatively large, so it is basically not produced by manufacturers, but if customers have such requirements, Hengxin will also provide them.
Nicotine is the No. 1 reason for the "throat feeling" of e-cigarettes. The higher the nicotine concentration in the e-juice, the stronger the "throat-hitting feeling", but at the same time, the taste of the e-juice will be weakened.
Many newcomers will ask: "What kind of nicotine-concentration e-liquid do I need?" This question is difficult to answer, because everyone's cravings and "throat-throbbing" needs are different, and the frequency of e-cigarettes is not the same. the same. Moreover, different atomizer structures, atomizer core settings, and atomizer airflow size will affect the "throat feeling" and "lung's absorption efficiency of nicotine", resulting in different personal experiences.
I had a pack of Double Happiness a day before I smoked e-cigarettes, and the nicotine concentration of 18mg/ml of e-liquid was slightly higher for me. When you choose the nicotine concentration, it is recommended to use 11mg/ml first, and then "decrease and increase" in the future (the nicotine concentration of 11mg/ml is also recommended by foreign manufacturers, and this concentration is a good balance between "throat hit" and "e-juice" "flavor", that is, to satisfy your cravings without losing too much flavor of e-liquid).
In any case, nicotine is always a harmful substance to the human body, which is also the reason why many people criticize "e-cigarettes" as unhealthy. But compared with the more than 4,000 harmful substances produced by cigarette combustion, nicotine is relatively healthy.
Propylene glycol (PG: Propylene Glycol for short):
It is a common drug and food additive, hygroscopic, slightly sweet, odorless, colorless and transparent, and its fluidity is similar to that of water. The U.S. Food and Drug Administration (FDA) describes PG as "generally safe for humans."
As one of the basic components of e-liquid (carrying nicotine and flavorings & flavors), PG is mainly used to "carry most of the flavor of e-liquid" and produce "a small amount of mist" and "throat hit". If you like "big smoke", then the PG content of the oil you choose should not be too high.
Although PG is generally safe for the human body, a small number of people still experience side effects such as throat discomfort, phlegm, and allergies. These side effects are short-lived and mild, as long as you stop smoking or switch to a low-PG content e-juice (some e-juices are PG-free).
Vegetable glycerin (referred to as VG: glycerin):
It is a more common drug and food additive (generally used to make cakes, chocolates and other sweets), very hygroscopic, sweeter than PG, odorless, colorless and transparent, and its fluidity is similar to that of edible oil.
As one of the basic components of electronic cigarette oil (carrying nicotine and flavoring essence), VG is mainly used to generate "a lot of mist. VG has no side effects on the human body (I have never heard of anyone allergic to chocolate), but due to its viscosity It will slightly increase the difficulty of cleaning the atomizer. If you see a certain oil that is relatively viscous, it means that the VG content is high.
Flavor:
Needless to say, the various flavors of e-juice are adjusted by flavoring agents. Flavoring agents and essences are easier to attach to PG (only relatively speaking, otherwise those pure VG e-liquids will be tasteless?). But it's worth noting: the higher the nicotine concentration in e-liquid, the less likely the flavors and fragrances are detected by the nose and mouth. Some flavored flavors can also produce a "throat hit", such as mint.
There are thousands of e-liquid manufacturers, but qualified vapers (people who smoke electronic cigarettes) still try to choose big brands and international brands. It is difficult for those small workshops and black-hearted companies to produce the flavorings and flavors of e-liquid to ensure the safety, and the taste and taste are even more difficult to say.
Please note: The same e-liquid may produce completely different personal experiences under different atomizers and settings. According to the knowledge provided in this article, everyone will not be completely confused when choosing e-liquids. To give a few examples: If you want a sweeter, more smokey, "throat hit" is strong: choose high VG, high nicotine, and a little mint-flavored e-liquid. If you want softness and moderate fog volume: select PG/VG, medium and low nicotine e-liquid. If you want a layered flavor: choose a low-nicotine e-liquid. If you think life lacks passion: choose high PG, high nicotine, pure mint flavored e-liquid.
