Propylene Glycol or Vegetable Glycerin E-Juice?

E-juice or e-liquid consistently contains one of two water soluble liquids meant to produce vapor and mimic the sensation of smoking a traditional cigarette. Those two liquids are propylene glycol and vegetable glycerin, but what makes them different?

Propylene Glycol

The more commonly used liquid of the two, propylene glycol (PG for short) produces a more pronounced throat hit. Some users have found their throats to be irritated after using a PG-based e-juice, with some even reporting allergic reactions.
PG adds a slightly sweet component to the overall flavor which allows complex flavors to not be overpowered by the chemical properties of PG. It is a thinner liquid which helps prevent residue buildup around the various mechanical parts of your vape.

Vegetable Glycerin

Used less often in e-juice, vegetable glycerin (VG for short) produces a smoother throat hit than PG. As a result of its smoother hit, many users have found their throats to be less irritated after vaping.
It has a higher viscosity than PG and a more pronounced sweetness as well. That sweet flavor can overpower an e-juice’s other flavors from time to time. Due to its thicker properties, VG will produce more vapor in each hit. That added thickness can also result in buildup around your vape’s mechanical parts, which may require cleaning more often.

PG or VG?

Choosing between the two types of e-juice ingredients comes down to personal taste, comfort and preference. As several vaping enthusiasts tend to migrate over to e-cigs from traditional cigarettes, choosing a PG-based e-juice will feel more familiar to them due to the stronger throat hit. Try both or, if you’re a chemist at heart, consider carefully mixing the two styles to create a custom vaping experience all your own.

  2. Vegetable Glycerin is an all natural liquid generally extracted from plant oils, in particular, soy, coconut oil, and palm oil. PG is the more popular e-liquid base, for many reasons.

  3. Vegetable glycerin is a considerably thicker solution, compared to propylene glycol. On its own, VG has a slight sweet taste which also makes the e-liquid sweeter and the flavors a little difficult to detect. While PG is know to give users a dry mouth, some vapers have complained about phlegm building up in their throat after suing vegetable glycerin-based e juice liquid.
