What’s e-juice made out of?

That’s a question that many individuals appear to be confused about. From well-meaning vapers who say “It’s just water vapour” (it isn’t) to tobacco management fanatics yelling, “We don’t know what’s in it” (we do), misinformation and bizarre beliefs about e-liquid are all around the place.

Fortunately, there’s no real mystery about how e-juice is made or what goes into it. In fact the ingredients are often all listed on the label. That’s the law in the EU and shortly will likely be in the USA, however reputable juice makers have been doing it for years anyway.

So it’s easy to seek out out what’s in your e-juice, but is that really very informative? Most of it’s chemical names, which can look intimidating – they usually also don’t say loads about what the substances really are. That makes it easy for folks to create scare tales, equivalent to “E-liquid contains antifreeze” (it doesn’t!)

Most e-liquid has four foremost ingredients; there’s some variation, but not really very much. If you understand the basics you’ll be able to identify any variations quickly. Within the meantime, right here’s what you can count on to be pouring into your atomiser.

Vegetable glycerin

Liquid designed for contemporary atomisers is generally vegetable glycerin, or VG – this may be up to 80% by volume. If you wish to know the way it’s that e-cigs have gone from producing slightly wisp of thin vapour to belching out big white plumes, this is why.

Glycerin is a pure substance that can be processed from most kinds of fat. The glycerine used in e-liquid comes from vegetable oils, which is why it’s called VG, nevertheless it doesn’t really make a number of difference. One important point is that although it’s processed from oils it isn’t an oil. Actually it’s an alcohol, which makes it safe to inhale.

VG is a non-toxic colorless liquid with no scent, but a sweet taste. It’s very thick and viscous, which means high-VG liquids don’t work well in older atomisers and small clearomisers – it’s too thick to wick well. Some liquids use aqueous glycerine to solve this, basically just VG with some water added.

A number of common products include VG. It’s used within the food business as a sweetener, and also added to some meals to maintain them moist. Many medicines contain it too. Scientists have studied it for years, and it’s by no means been linked to any health problems.

Liquids with a whole lot of VG produce numerous dense vapour, but not a number of throat hit.

Propylene glycol

Most of what isn’t VG in your liquid is probably propylene glycol, or PG. Some liquids include more PG than VG; these work better in clearomisers and older atomisers, because they’re less viscous.

PG is an alcohol, like VG, and it’s additionally nearly odourless. It has a faint sweet taste, though not enough for it for use as a sweetener; it does get added to foods, medicines and other products to keep them moist, though.

One other use for PG is in antifreeze, and it’s because of this that some people like to claim e-juice contains antifreeze. In truth this is totally dishonest. PG is only one ingredient in antifreeze, and it’s really there because it’s non-poisonous; PG-based antifreeze is less dangerous to children and pets. It’s worth stating that water is also an ingredient in antifreeze; just because something is used in a product that has a status for being toxic, that doesn’t say anything about how dangerous that substance is.

It’s true that there have been some minor health points linked to PG. It’s been studied for the reason that Forties and is classed as generally safe; swallowing or inhaling it won’t do you any harm. A small percentage of people are delicate to it, though, so if liquid with a high PG content material makes you are feeling unwell, swap to one with more VG.

PG produces less visible vapour than VG, so it’s unpopular with cloud chasers but liked by individuals who wish to vape discreetly. It additionally carries flavours higher and gives more throat hit.


Among the finest things about vaping is the wide selection of delicious-tasting juices, and that’s all down to flavourings. Liquid doesn’t have a lot style on its own, so it’s flavoured with meals-grade additives.

If there are any health concerns about vaping that’s mostly down to flavourings. There are some ingredients which can be safe to eat however not to inhale – diacetyl, for example. Nonetheless, the business has finished well at eliminating additives that there are worries about. Don’t use meals flavourings from the supermarket although; some of them contain oils, which are harmful if inhaled. Stick to flavours from vape manufacturers, because these have been elected for maximum inhalation safety.


Finally, most liquids include nicotine. This is what makes vaping such an efficient substitute for smoking; you can fulfill your nicotine cravings with out having to set fire to tobacco leaves. Nicotine also gives a great throat hit, so if this is vital to you strive higher-nicotine liquids.

Although it gets loads of bad publicity, nicotine is actually a very safe drug: It’s the smoke from cigarettes that causes harm, not the nicotine. It’s toxic in high does, but there’s really no likelihood of poisoning yourself by vaping. Long before you get to a dangerous stage it will make you’re feeling slightly nauseous, then give you a headache. Vapers (and people who smoke) are excellent at getting just as a lot nicotine as they want, and no more.

It’s normally finest to avoid e-liquids that include anything apart from these 4 ingredients. Nutritional vitamins, colouring, supplements like caffeine – these don’t do anything for the standard of your vape, and unlike flavourings they haven’t been selected for inhalation safety. However when you follow the ingredients listed here you’ll be able to look forward to a low-risk and luxuriate inable vaping experience.
