PG and VG – What Are They?
PG and VG – What Are They?
Anyone new to vaping will start to recognise the terms PG and VG and wonder what they are. Well, they’re pretty much the staple ingredients in every e-liquid you vape.
They can be confusing, and of course there are many vaping myths out there, but understanding exactly what PG and VG are and how they work can enhance your vaping experience.
In this article, we will look into exactly what PG and VG are, and how choosing the right ratio will ensure you enjoy your vape even more. So, with that said, let’s dive straight in…
PG and VG - What Are They?
PG (Propylene Glycol) and VG (Vegetable Glycerine) are the two main elements in most e-liquids and a higher proportion of one or the other will make a huge difference to your vaping. So, let’s take a closer look and decipher exactly what PG and VG are.
What is PG (Propylene Glycol)?
Propylene Glycol (PG) is a chemical composition with many uses. It is a colorless liquid that is virtually odorless but has a very mild sweet taste. It’s safe and non-toxic and is used in many e-liquids.
It’s widely used in industrial, pharmaceutical, and food processing applications. You will find it in things like salad dressings, soups, asthmatic inhalers, make up, and shampoo among other things.
In vaping, PG helps with the vaporization of e-liquids and offers a smoother vaping experience. It also helps give e-liquids their amazing flavours, as it acts as an emulsifier with food flavourings and ensures no overpowering taste.
This makes it ideal for flavoured juices, so if you’re looking a flavoursome vape, e-liquids with about 70% PG might be the best for you.
PG has a thinner consistency than VG, and is only slightly thicker than water, so e-juices with a higher PG ratio are easier to absorb allowing you to get more rapid vapes.
Higher PG ratio e-liquids won’t mess your coils up as quickly, so you won’t have to clean your kit as much if you use them.
PG has a stronger hit than higher VG juices, so anyone who has quit smoking might prefer a higher PG ratio e-liquid to get that stronger throat hit they might be used to from smoking cigarettes.
What is Vegetable Glycerine (VG)?
VG is a non-toxic, colourless and odourless alcohol that’s also found in e-liquids. It’s thicker than PG and has a sweet taste, and is widely used in many industrial and consumer products such as soap, detergents, medicinal products, cosmetics, foods and drinks.
VG used in most e-liquids is made up of 99.5% glycerol, so if you see the term ‘glycerol’ it will be the same thing. VG is plant based, hence the term Vegetable Glycerin, but you can also get it glycerin from animal fats.
VG has a thick gooey, consistency, so it has a slower absorption rate than PG. This means it takes longer for an e-liquid with a higher VG ratio to fully absorb into the wick of your vaping device.
Its thick consistency means it is messier than PG, so you will be cleaning your equipment more regularly.
However, the thick consistency isn’t all bad as it allows for producing thick, dense clouds that’s associated with vaping. So, if you’re a cloud chaser, getting an e-liquid with a higher VG ratio will definitely give you the option of producing some nice, dense clouds.
Which e-Liquids Are Best for Different Ratios?
Standard e-liquids vary in ratios, and it's these that you can pretty much get any ratio to your liking. The most popular ratios are anywhere from 50:50 up to 80:20 either way.
Nic salts are generally 50:50 ratio, but because the nicotine salt is stronger than freebase nicotine e-liquids, they're ideal for anyone giving up smoking, but doesn't want to go too high VG.
Shortfills usually have a higher VG ratio, so you'll get thicker clouds from these e-liquids. But of course, shortfills don't have any nicotine, so if you want to add some, it may lower the ratio.
Therefore, make sure you get the nic shot with the ratio to match your desired PG/VG ratio.
PG and VG – Now You Know What They Are
PG and VG are the two main components found in pretty much every e-liquid you can buy. They both play their part in making the perfect e-liquid, which you now know is a matter of personal preference.
The best PG/VG ratio depends on a few factors, and whether you demand a rich fruity flavour when you vape, or want to produce nice, dense clouds, getting the PG/VG ratio right will play a key role.
It’s always a good idea to start vaping with a 50:50 ratio and try different juices from there. It will take time to discover your preferred ratio, but life is about the journey, not
