When it comes to making up your own e-liquid or buying ready make e-liquid, you’ll come across two particular ingredients in every mix. They are called PG, which stands for Propylene Glycol and VG know as Vegetable Glycol.
While others use all manner of flavourings and distilling solutions, every blend will use some mixture of PG/VG. What is it, you ask? And is it even safe? It’s two particular forms of liquid.
The two main ingredients that make up an e-liquid and provide the vapor clouds and ‘‘throat hit‘‘ are propylene glycol and vegetable glycerol (also known as PG and VG).
Let’s break it down in details
PG (Propylene Glycol)
The first, PG, is known as Propylene Glycol. It’ a particular base liquid that is very popular in the use of e-liquid creation. One of the reasons for that popularity, among others, is the fact that it’s entirely colourless, odourless and organic. It’s approved for use and is regularly used in not only e-liquids but food products as well.
- Produce a better ‘‘throat hit‘‘ feel
- Thinner consistency then VG
- Carries flavor more effectively than VG
- Less vapor than VG
- Doesn’t have any taste
VG (Vegetable Glycol)
The other product, VG, is Vegetable Glycol. VG is very popular for many reasons, and the word ‘vegetable’ should make you feel good. Sadly, it won’t count as one of your ‘five a day,’ but it does become a major part of any mixture you make. It’s FDA-approved and is often used in food products, too. It’s also a part of cosmetic products.
- Produces a bigger vapor clouds
- Thicker consistency than PG
- Sweeter than PG and it may have an impact on flavor
- There is almost no throat hit
Now, the majority of e-liquids will use a blend of both in ratio 50/50, though some will go heavily with one or the other as the main base. Let’s have a look what an impact those ingredients have in vaping, clouds and taste.
