What is PG/VG?

Wednesday, 20 April 2016  |  Admin

If you're new to vaping, all the terminology might be a bit confusing at first, and you might not know your atomisers from your APV. If that's the case, worry not, because at Vape Mountain we're here to explain. One of the main issues prospective vapers might have is not knowing about the contents of e-liquids, and the main ingredients; PG and VG. Propylene Glycol (PG) and Vegetable Glycerin (VG) are integral parts of the vaping experience, and this article seeks to shed some light on these mysterious substances.

So, What Are They?

PG and VG are the odourless liquids that combine with nicotine (sometimes) and flavouring to create e-juice. When heated, they produce vapour, and the inhaling of this vapour is what 'vaping' actually is. The two substances are usually used together in e-juices, but the ratio of each varies dramatically depending on what set-up you're using or just personal preference. PG is thinner and creates a better 'throat hit', while VG is thick, sweet and creates large amounts of vapour.

Vegetable Glycerin

PG

Propylene Glycol is an organic compound. It has no colour or odour, and is much thinner than VG. It is also more effective at providing a throat hit, which users claim is a sensation similar to smoking tobacco. PG's main benefit is that it carries flavour better than VG, allowing you to get the most out of your vaping.

VG

Vegetable Glycerin is a natural chemical derived from vegetable oil. It is a thick, heavy liquid with a slightly sweet taste, and is often used to give a 'thick' sensation to vapour. The hit from e-juices high in VG is a lot smoother than PG. VG also produces large amounts of vapour, making it desirable for vapers who try to make the biggest clouds possible (cloud chasers). VG's main drawback is that it can clog up your equipment and be hard to clean.

What's Your Goal?

Your chosen ratio of PG and VG is all down to what type of vaping you prefer, as they are both suited to different things. If you value flavour and throat hit above vapour then a high percentage of PG is probably for you, whereas if you're looking to get into cloud chasing/sub-ohm vaping VG is the better choice. If you're not bothered by any of these things and just want one which feels the best to you, it'll probably take some trial and error, but just experiment with a few concentrations and see what suits you best.

Are They Safe?

Studies have shown that PG is safe to ingest orally, and it is "generally recognised as safe" by the FDA as a food additive. Not enough study has been done on inhaling PG to make any definitive statements though. Some people may find a high concentration of PG irritating to the throat, and allergies are very rare, but have been reported. Should you come out in a rash, or experience any other unpleasant symptoms, then it's probably best to switch to VG.

VG is also "generally recognised as safe" by the FDA and is one of the most benign substances around, being used in beauty products, soap, and as a sweetener in various foods. The risk of allergy is also low, and while there hasn't been much study done on inhaling VG, everything points to the fact that it would have a minimal effect on health.
