Vegetable Glycerin vs Propylene Glycol a Complete Guide

This article will tackle the Propylene Glycol (PG) VS Vegetable Glycerin (VG) debate. What they are and the role that they play in vaping. The Throat hit, viscosity, and more will be discussed in this article.

Vegetable Glycerin and Propylene Glycol

They are both colorless liquids that serve as a base for your liquid. They both play a role in just how big the cloud of smoke you get is. Vegetable Glycerin also alters the taste a bit. Propylene Glycol, on the other hand, plays no role in the taste. It is a bit more runny liquid than Vegetable Glycerin.

Smoke Comparison Propylene Glycol Vs Vegetable Glycerin

Now that we have an idea of what exactly VG and PG are let's take a look at their role in smoke production. Let’s face it sometimes we want a huge cloud of smoke when we are hanging around with friends. Other times we want a next to a non-existent cloud of smoke when we are in a more formal setting.

Vegetable Glycerin offers more smoke and is ideal for those memorizing tricks. If you guys want to learn how to do some and enter our giveaway contest click here. Vegetable Glycerin in its very nature is a thicker liquid that directly correlates to the amount of smoke produced by your vaping device. As far as smoke production this is the way to go. Look for bottles that contain a higher Vegetable Glycerin to Propylene Glycol base if this is what you are after.

Perhaps large clouds of smoke aren't your thing, maybe you vape in an office setting. Or maybe you just don't want large clouds of smoke in your house. Whatever the case may be for smaller clouds a Propylene Glycol base is right for you. Propylene Glycol is a very runny/thin liquid that offers quick absorption for your device which directly translates to smaller clouds of smoke. When looking for small clouds of smoke make sure your base contains more Propylene Glycol than Vegetable Glycerin or at least a 50/50 ratio of the two.

Throat Hit Propylene Glycol Vs Vegetable Glycerin

Concerning throat hit, PG is the winner. While Vegetable Glycerin does offer a hit it is just not the same as a PG based liquid. For that stronger hit, you want to go with a Propylene Glycol base. For people who don't like a strong hit Vegetable Glycerin is the way to go. This is completely based on preference and something that you will need to experiment with in order to find your ideal balance.

Viscosity of the liquids/How fast are they absorbed

As previously mentioned Vegetable Glycerin is a thicker liquid which means a slower absorption time for your device. This also means more gunk build up when you are smoking liquids that contain a large amount of Vegetable Glycerin. With a slower absorption rate, this simply means you may have to take more hits or wait a bit longer until you feel the full effect of the liquid.

On the other hand, PG is a runny liquid almost water like in the way it moves. It is quickly absorbed by your device and does not create as much build-up meaning less cleaning time. If you're looking for a liquid that requires less cleaning and absorbs quicker a Propylene Glycol based liquid is the way to go.

How do I know which liquids contain this?

In order to know which liquids contain Propylene Glycol or Vegetable Glycerin for that matter, a simple examination of the bottle should offer the solution. Most products contain a 50/50 mixture of each of the components but some offer a higher Propylene Glycol or Vegetable Glycerin base depending on what exactly you’re looking for in the liquid. Take a look here at the e-liquids we offer.

How do they taste?

When it comes to taste Propylene Glycol has none, simple as that. Vegetable Glycerin offers a bit more sweet flavor which some people say detracts from the intended flavor of the e-liquid. But some would argue that in sweet-tasting flavors it only adds to the effect.

Are they harmful?

Overall there are no major known side effects from vaping with Propylene Glycol. As mentioned above some people do find that they have a minor allergy in which they feel itchy or sensitivity in some areas, if this occurs the vaping should be stopped immediately. You could consult a physician or switch over to a purely Vegetable Glycerin e-liquid where fewer users have reported allergies.

As with Propylene Glycol, there are no major known side effects from vaping with Vegetable Glycerin. Neither base Vegetable Glycerin or Propylene Glycol is known to cause a significant percentage of the population allergies or any other ill side effects. Propylene Glycol has a slightly higher rate of people who are allergic to it which is why some people choose to simply vape with Vegetable Glycerin only liquids. If you are allergic it mainly comes in an itchy throat/ itchy sensation. If this occurs vaping should not continue and you should either try a different base or consult with a doctor before attempting to continue vaping.
