PG and VG: What’s In Your E-Liquid?

Have you ever wondered what’s in your e-liquid? In this comprehensive guide, you’re going to find out. Here, we’re going to go into detail about the two main components of e liquids, and what difference they make to your vaping experience, as well as the flavour of your liquid. Read on to learn more.

What is PG and VG?

PG and VG are used as a base for e liquids. They can be synthetic or derived from animals and plants. PG and VG are often used in different ratios depending on the desired taste of the e juice and who it is for.

VG is a derivative of vegetable oil and is used to thicken the consistency of e-liquid. This then creates dense vapour clouds that many people who partake in sub-ohm vaping enjoy.

PG is propylene glycol and has a thin consistency. This is the component that often provides the bigger throat hit and is closely linked to the sensation of smoking. It is also sometimes used to carry flavour in food products. You can learn about these different elements, as well as the best PG VG ratio below.

VG - Vegetable Glycerin

VG is vegetable glycerin, a derivative of vegetable oil. This ingredient is used mostly for thickening an e-liquid and therefore creating more dense vapour clouds. This makes a higher VG liquid better for those who enjoy sub-ohm vapour and like to ‘throw clouds.’ VG also has a slightly sweeter taste, so it can be good for the flavour of an e-liquid. In terms of the ratios of PG and VG, you’ll likely find that an e-liquid higher in VG is a sweeter flavour, such as a dessert flavour or bubblegum flavour.

What are the effects of VG in e-liquid?

The main effects of VG in an e-liquid are the sweet flavour and the huge clouds that the person vaping can enjoy when using it. Of course, the PG VG ratio must still be correct, but the best PG VG ratio will all depend on that person’s preferences. Generally, if you’re somebody who enjoys thick, luscious clouds while vaping, a higher VG liquid will likely be your best bet. In some cases, you can vape a liquid that is 100% VG safely due to its thickness. However, this may need to be a DIY juice, as many vape stores offer a mixture of PG and VG only.

How else is VG used?

Vegetable glycerin is not only used in e-liquids, but in cosmetics, pharmaceuticals, and foods.

PG - Propylene Glycol

PG is a substance that is commonly used as a food additive, and even an ingredient in cosmetic hygiene products. It has been declared safe to use in foods and is therefore safe to use in various e liquids along with VG to create the perfect blend based on the desired vaping experience.

What are the effects of PG in Vape Juice?

PG is used in vape juice to give more of a throat hit, making it a more popular choice with those who are trying to quit using cigarettes. It also thins out the liquid, making for more moderate, and even subtle plumes of vapour. If a person trying to quit smoking were looking for the best PG VG ratio, they would likely go for something higher in PG to give them the experience closest to smoking.

How else is PG Used?

Propylene glycol is used in a range of oral and topical medicines. It can also be used as a drug stabilizer and solvent.

Can you be allergic to PG or VG?

Allergies to PG and VG are extremely rare, and only 1 in 1000 people suffer from some kind of intolerance. Even if an allergy is present, the symptoms are often so minuscule that the person does not even notice them.

Understanding PG and VG for DIY e Liquid

Many people enjoy making their own vape juice, in which case, understanding the ideal PG VG ratio is crucial. This is the only way to ensure your DIY vape juice provides the vaping experience you are looking for. If you’re looking to make your own vape juice it may be worth getting an E Liquid Mixing Kit, and check out our guide on making your own e liquid.

Below, we have PG and VG ratios that you can use as a starting point. You can test each one until you find your perfect mix.

PG and VG Ratios

50 VG / 50 PG

This is equal parts PG and VG. This is often found in cheaper, more basic flavours. Clouds will be mild, and the experience will provide a good throat hit for those who feel they need it.

60 VG / 40 PG

This ratio will give less of a throat hit, with moderate clouds of vapour. It’s popular with those who still enjoy a slight throat hit but enjoy the experience of vaping for the thick vapour clouds.

70 VG / 30 PG

This ratio gives a barely noticeable throat hit, with plenty of vapour clouds. Of course, there is the option to go even higher in VG for those who want even bigger clouds or are considering entering competitions.

PG VG Ratio Summary

In short, the more PG in a vape juice, the thinner the liquid and the stronger the throat hit. More VG gives more vapour and a sweeter taste overall. It’s crucial to find the right mix for your needs when mixing your own e-liquid.

Specific Vape Mods for VG and PG

The mod you are using to vape with will also either enhance your vaping experience or dampen it. Making sure your mod is fully suited to the juice you are vaping is essential. If you’re planning on vaping a high VG liquid, for example, you’re going to need quality sub-ohm coils to really bring out that flavour and support vapour production. A vape that allows you to go above 60 watts and beyond will also provide a much more satisfying vape experience. However, those who prefer lower VG and high PG would likely prefer a small mod with low wattage to give the desired experience. Check out our range of vape mods to find your ideal piece of kit.
