Learn about Propylene Glycol (PG) in e-cigarette essential oils.
Propylene Glycol abbreviated as PG is a solvent commonly used in the food, pharmaceutical and cosmetic industries.
PG is a colorless, odorless liquid at room temperature. PG can easily transform from liquid to gas when gently shaken or heated at a temperature slightly higher than normal temperature. Therefore, it is used as a solvent in electronic cigarette essential oils so that the combustion chamber can produce smoke at a lower temperature than regular cigarettes.
Learn about Vegetable Glycol (VG) in e-cigarette oils.
Compared to PG, Vegetable Glycerin (VG) has a superior advantage when used as an essential oil in electronic cigarettes. The most noticeable difference from users is that it creates a sweet taste when using electronic cigarette essential oils with VG. In addition, electronic cigarette essential oils with VG do not cause dry lips like electronic cigarette essential oils that only use PG, and at the same time, it also promotes the smoke creation process better than PG. Therefore, electronic cigarette essential oils with VG always bring a better feeling of use than electronic cigarette essential oils that use PG.
The most important point of a growing industry is the speed at which new products are released to the market, and the e-cigarette industry is no exception to that objective trend. In fact, according to Forbes magazine, e-cigarettes are one of the fastest growing industries in the world today. However, the downside is that it is difficult for users to recognize the advantages and disadvantages of new products, which leads to confusion when consumers want to choose a product that suits their needs. And for e-cigarette users, the quality of essential oils is always a big question mark.
Normally, e-cigarette essential oils are usually made up of 1 of 2 basic ingredients: Vegetable Glycerin (VG) or Propylene Glycol (PG). Later, some essential oil manufacturers combined these 2 ingredients to create essential oils with newer advantages. Then nicotine and flavoring will be added to create a complete essential oil product. Therefore, to determine which essential oil is right for you, you must clearly understand their structure as well as their advantages and disadvantages.
In general, essential oils containing PG are more commonly used than VG. PG is a colorless, odorless, tasteless substance and therefore does not affect the flavor of essential oils more than VG. At the same time, because the molecular density of PG is thinner than VG, it will cause less residue in the combustion chamber or essential oil chamber than VG. However, the downside of PG is that it can cause allergies in a small number of users through symptoms such as dry lips, sore throat, and skin rash. For those with a history of allergies to PG, essential oils containing VG are the optimal choice for you. In addition, another disadvantage of PG is that it often leads to dry lips and dry mouth when used regularly.
In contrast to PG, VG hardly causes allergies to users. However, because the molecular density of VG is denser than PG, essential oils containing VG often cause the combustion chamber and the essential oil tank to be frequently clogged with residue, so you will have to clean your e-cigarette more often. Another small disadvantage of VG is that although it is chemically tasteless, in reality, essential oils containing Vegetable Glycerin (VG) may have a slightly different taste than essential oils containing PG due to the impact of VG on the flavor of the essential oil.
Therefore, to limit these disadvantages, manufacturers now tend to blend PG and VG together in a ratio of 33% VG/67% PG or 20% VG/80% PG. However, this type of essential oil is still not suitable for people with PG allergies. However, this combination has created a new generation of essential oils that provide a better feeling when used than the other two types. And maybe in the future there will be a new line of essential oil products that completely overcome the disadvantages of current essential oils.
