Propylene Glycol (PG) is a much thinner tasteless liquid. PG produces more of a “throat hit” than VG does, which simulates the feel of smoking better. PG also has a higher rate of sensitivity for some people, meaning that some people just can’t use PG in their vape.
E-liquid is a mixture of varying amounts of 3 different ingredients. Nicotine, PG (Propylene Glycol), VG (Vegetable Glycerin) and flavoring. These are the main ingredients to all e-liquid.
The amount of nicotine is dependent on the strength of nicotine in your e-liquid, but let’s say it is around 10% nicotine. Somewhere around 10% of your e-liquid will be flavoring. That leaves 80% of the liquid in your bottle for fillers, which dilute the flavoring and the nicotine. This is where PG and VG come in, and depending on how you like your vape, that determines the percentage of PG and VG in your e-liquid.
Vegetable Glycerin (VG) is a thick, sweet liquid. VG produces luscious clouds of vapor. VG also imparts a sweeter taste to your liquid.
