How to distinguish the quality of e liquid?

The most direct manifestation of vape is that it is healthier than ordinary cigarettes. It is e liquid. After atomization to generate smoke, it simulates the effect of smoking. E liquid contains trace nicotine to achieve the effect of relieving craving. At the same time, e liquid itself does not contain tar and carbon monoxide. And other harmful substances, greatly reducing the damage to the body. Therefore, everyone thinks that vaping vape is healthier than vaping traditional cigarettes. But if the quality of the products is good or bad, the e liquid is the same. How do we distinguish the quality of the e liquid?

As we all know, the main components of e liquid are: vegetable glycerin, propylene glycol, flavor and nicotine. If we want to identify the quality of an e liquid, we need to understand the basics of e liquid. Among the above four ingredients, by adding different combinations of various flavors, that is, the so-called formula is formulated, it directly reflects the taste and taste of the e liquid, so the essence is the most valuable in e liquid. The core component, the cost of the fragrance may also account for 80% to 85% of the cost of the entire bottle of e liquid material.

Regardless of the taste factor of e liquid, how to distinguish the quality of an e liquid is mainly to look at the raw materials used in this e liquid. This refers to the use of e liquid fragrance raw materials, because different flavors will use different solvents. At the same time, the solubility of different flavors in vegetable glycerin or propylene glycol is also different, and the chemical stability at atomization temperature is not exactly the same. At the same time, vape fragrance is still a new product, there is no clear plan to develop a category, so the fragrance used by vape needs a careful screening by the perfumer. In some cases, some substandards are added to increase the rich taste. The possibility of flavor still exists greatly.

We are not a perfumer of e liquid, so it is impossible to distinguish its quality from a very subtle place, but we can understand it in a larger direction, such as their type:

A high quality e liquid must be food grade. In the process of making finished fragrances, manufacturers will add different additives according to their different formulations and production processes. Simple and coarse, the essence is divided into synthetic flavor and natural flavor, the difference between the two is still very large:

Natural flavor is the direct extraction and filtration of the fragrance-containing substances from the animals and plants, which better maintains the aroma characteristics of the original flora and fauna, the aroma is more natural and soft, and the manufacturing cost is relatively higher.

The chemical essence uses natural flavor as a template, and the characteristic identifiable part of the natural flavor is prepared by chemical analysis and artificial synthesis. The general synthetic flavor contains dozens to dozens of compounds, and the fragrance is relatively easy to make. It is more intense and at a lower cost. The fragrance of natural flavors is natural, elegant, fresh, not nasal, and the divergence is relatively fast.

The aroma of the synthetic essence is strong, and the fragrance is not volatile. If the concentration is not well controlled, the fragrance will suffocate. From the price comparison, natural flavors are much more expensive than chemical fragrances, generally 3 to 5 times the price, and a few can reach a price difference of 10 times or more. That is to say, e liquid with roughly the same taste, if chemical flavor is used, the cost is reduced by 60% to 80%.

A high quality e liquid vegetable glycerin and propylene glycol must also be food grade or pharmaceutical grade. These two substances are widely used in various fields of medicine, food, and chemical industry. But not only vegetable glycerin and propylene glycol can be added to the e liquid, they are also graded.

In general, we will be divided into food grade and industrial grade. The difference between the two is not a star or a half. Food grades have strict requirements on the purity of raw materials, ingredients, packaging containers, transportation environment, and the number of bacteria. For example, the barrel for packaging vegetable glycerin has strict requirements on the inner wall coating material of the barrel, and needs to be resistant to corrosion and falling off. At the same time, the sealing rubber ring of the lid must also be made of non-toxic and corrosion-resistant silicone material. Therefore, food grade materials tend to be much higher in price than industrial grade materials.

Nicotine is also different. This substance is an alkaloid widely found in Solanaceae, and it is also the main cause of smoking addiction, but nicotine is not the direct cause of cancer. This pot of nicotine has been backed for many years. In fact, the rate of metabolism of nicotine in humans is very fast. Generally speaking, nicotine is completely metabolized from the human body within 24 hours. Of course, the absorption rate of nicotine is not generally fast. Therefore, the quality of nicotine is often ignored by players, but nicotine is also very tricky. The quality of nicotine depends mainly on the purity of nicotine. The higher the purity, the higher the price of nicotine. High-purity nicotine is generally used in the pharmaceutical industry, while low-purity nicotine is generally used in agriculture and chemicals to make products such as strong insecticides. The difference between the two can be three to five times higher. Nicotine used in vape should use high purity pharmaceutical grade nicotine.

A good quality e liquid should be prepared with natural finished flavor + food grade VG & PG + medical nicotine, which is the principle that vape manufacturers should abide by. Due to the fact that the manufacturer has already added some solvents according to their own formula and production process, in order to better reflect the health concept of e liquid, in principle, in addition to the above ingredients in e liquid, there is no clear research results. Under the circumstance, no other additives or other raw materials should be added, and the probability of a bad chemical reaction caused by the heating of the e liquid is increased. Of course, doing so may lose a certain taste. This is what the benevolent sees the wise and sees wisdom.

The most direct way to judge the quality of a product before use is to use eye recognition, so we can judge the quality of e liquid from the appearance and smell.

1, look at the color
In the absence of nicotine, the e liquid is generally colorless or pale yellow. If you add some heavy-colored extracts, there will be a corresponding color. If you have nicotine or add too much natural extract, the coloration will be more unstable. After one or two days or after exposure to sunlight, it may change color. Fruit color More unstable, I think tobacco and mint are generally the Premium in light yellow or golden yellow.

2, smell smell
The smell of the first feeling should not be unpleasant. You may not like the taste, but it should not be an unpleasant rejection, except for female compatriots, especially tobacco or nicotine.

3, see 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 e liquid. I think that if the two are well matched, it will be cool. Relatively speaking, the e liquid with a large amount of smoke is better than the small one. It is effortless to vaping, and the smoke is delicate and moist. A burnt smell may be related to e liquid, but the atomizer may be higher.

Then it is vaping, the good e liquid taste is relatively stable, the difference in taste will not be very large at the entrance and into the nasal cavity. In general, the smell of smoke in the mouth should dissipate within three to five minutes after you breathe out the smoke.

1, the feeling of the throat
The friend of vaping smoke knows the feeling of the throat. The written point is the impact on the throat. This is mainly the effect of nicotine. The e liquid without nicotine basically has no impact on the throat, but too high nicotine will have a thorn. Pain, we can still stand the 18MG is not bad, no need to have at least 10 years of smoke age in 8 years, you still do not choose high concentration. For our domestic flue-cured cigarettes, the amount of nicotine similar to its impact is 6-9MG. If it is a foreign heavy-smelling brand of cigarettes, such as Red Marlboro, camel, American spirit, etc., it needs to be around 12MG. Foreigners generally have a heavy taste. A good e liquid has a high concentration of nicotine. There is not much tingling in the throat. A bad vaping is like a needle.

2, the feeling of the lungs and nose
If you can't pass the throat, you can't pass the lungs and nose. The feeling of crossing the lungs can't be described by words. If you pass the nose, you will really appreciate the taste of this e liquid. And in the step of smelling above, what you smell is just the taste of the surface. In general, the good e liquid overall feels comfortable and can taste the taste.

3, the feeling of mouth after vaping
Many people responded that vaping the vape mouth and throat will be very dry, a bit dry is right, it will be good soon after stopping, because PG, VG is absorbent, but it is dry, then it is wrong. If the frequency of your vaping is too high, of course you will feel dry, chewing gum is delicious, you eat a little more in a short time, your teeth will be sour. You can still feel the taste of this e liquid in a short time after stopping vaping.

Finally, let's talk about the basic characteristics of qualified vape e liquid:

First: health and safety.
Second: don't get angry.
Third: no dizziness.
Fourth: not sweet.
Fifth: Do not work.
Sixth: e liquid color is pure.
Seventh: full of aroma, but can not overshoot
Eighth: Not disgusting.
Ninth: Do not affect appetite.

It should be pointed out that if there is obvious physical discomfort during the use of e liquid, it is Premium to stop using it immediately to prevent more serious problems. After all, health is the most important thing!
