What does PG/VG mean in an e-liquid?

The e-liquids used in electronic cigarettes contain two main ingredients: PG (propylene glycol) and the VG (vegetable glycerin). Understanding what these terms mean and what their roles are in e-liquids is essential for any vaper, beginner or experienced, as it impacts the vaping experience. \n

Propylene glycol (PG)

\nPropylene glycol is a colorless and odorless chemical compound used in a variety of food, pharmaceutical and cosmetic products. Part of the composition of many e-liquids, PG is appreciated for several reasons. The main one is that PG is notably responsible for what we call the “hit”, that is to say the tingling sensation in the throat that we feel when inhaling. This sensation is similar to that produced by tobacco cigarettes, making it a popular choice for smokers who want to quit smoking. \n\nPropylene glycol is fluid, making it easy to absorb for narrow aperture resistors that have a high ohm rating. These are the coils that are found on electronic cigarettes for beginners. It is therefore recommended to buy e-liquid in 50/50 PG/VG, that is to say with a propylene glycol/vegetable glycerin ratio of 50/50 or even richer in PG (60/40 for example ). This is the case of the entire liquido range For example. \n\nHowever, propylene glycol can cause dryness or even irritation in certain people, particularly in the throat and mouth. Although rare, an allergy to propylene glycol can also occur, requiring the purchase of PG-free e-liquid. \n

Vegetable glycerin (VG)

\nVegetable glycerin is a viscous liquid with a rather sweet taste, mainly extracted from vegetable oils such as palm or coconut oil. It is a main ingredient in e-liquids because it ensures the production of vapor. The more vegetable glycerin there is, the thicker the vapor the electronic cigarette produces. This vapor is also gentler when the e-liquid is rich in vegetable glycerin (PG/VG 40/60 for example) than when it is rich in propylene glycol. \n\nAs it is thicker than the propylene glycol, e-liquids with a high VG rate are compatible with so-called subohm electronic cigarettes, that is to say having resistances with a low ohm value. \n

PG/VG ratios

\nE-liquids are available in different PG/VG ratios: \n

\r\n
• PG/VG 50/50: a balance between PG and VG, offering a good combination of hit and vapor production, while preserving flavors well. Compatible with beginner equipment.
\r\n
• PG/VG 60/40 or 70/30 or. 80/20: a ratio favoring hit and flavor, with moderate vapor production. Compatible with beginner equipment.
\r\n
• PG/VG 40/60 or 30/70 or 20/80: a ratio for big vapor with a soft hit, for advanced or expert equipment.
