VG & PG E-Liquid — What’s the Difference?

There are many different brands of e-liquid/vape liquid for your e-cigarettes and personal vaporizers, and as well as many different brands, there are also many different types. This can make life difficult when choosing the right one, especially if you are a newbie to the world of vaping.

You will find a few different ingredients in your e-liquid but two that you are almost one hundred percent guaranteed to come across are VG and PG – Vegetable Glycerin and Propylene Glycol. These are two FDA approved ingredients and are also commonly used in things like beauty and cosmetic products, various medications, and even in some food items. Surely if it’s OK for you to eat, it’s OK for you to inhale, right?

This is normally the thicker, sweeter of the two liquids, and is much heavier too. If you seem to find that your e-liquid is congealing, going much darker, and becoming too thick to smoke at the bottom of your tank or cartridge, you might want to switch to an e-cigarette liquid that contains less of this VG component.

This is the part that creates the most vapor, and also gives you a pretty impressive throat hit. It comes from vegetables, just as the name suggests.

This is a much thinner liquid but proves to have an even sweeter taste than the VG stuff. This gives you more in the form of throat hit and vapor and is perhaps more preferable among the e-cigarette smoking community.

Most of the time you will find that your e-liquid is a nice combination of both VG and PG ingredients, although it has been suggested that the right mix for both throat hit and plenty of vapor is to have a 70/30 split – 70% of PG and 30% of VG. This gives you the right amount of sweetness and hit to the throat of PG, while still giving you the vapor normally associated with PG.

As a general rule, the higher the PG level, the more vapor you all get from your e-cigarette.

There are other ingredients that you will find in your e-liquid. Distilled water is normally added, for example, to think down the ingredients, especially in high VG ratio liquids, and you can’t forget about the nicotine content of course! This is what gives you the hit you need!

Most websites that offer e-cigarettes or e-liquid will give you some idea of the ratio and ingredients of their cartridges and e-liquids. V2 Cigs, for example, gives you a comprehensive guide to the ingredients in each and every one of their liquids on a, especially downloadable page. If you can’t find the ingredients listed on your liquid somewhere, or at the very least on the website, you should probably avoid using them.
