What Are the Main Ingredients in E-Liquids?

X2 Cigs supply high-quality e-liquids to vapers based in the UK, Australia and New Zealand. All of our R&D is based in the UK, where we work hard to ensure that our products meet the highest standards and contain only top-quality ingredients. We realise that this is one of the primary reasons our customers choose our e-liquids again and again.

But what exactly goes into your favourite vape? You may be surprised to find that our e-liquid solutions have refreshingly few ingredients:

• Propylene glycol
• Vegetable glycerine
• Flavouring
• Nicotine (optional)

In the following sections, we’re going to take a closer look at each of those ingredients.

Propylene Glycol

When you’re reading e-cigarettes forums, you’ll often see this abbreviated simply as ‘PG’. This compound is sometimes added to food and medicine to keep them moist by absorbing and retaining water.

PG contributes to the vapour created by an e-cig (though, as we’ll see in the next section, another ingredient is better at this). However, its primary function is to carry the flavour added to the e-liquid by holding it in suspension.

Depending on where you look for information, you’ll find varying reports on whether or not propylene glycol is safe to inhale. Some point out that PG appears in everything from cupcakes to soft drinks, which means it’s clearly safe to ingest. Others are quick to counter that eating and inhaling a substance are two very different things.

While the latter is certainly a valid point, it’s worth noting that PG is also present in most asthma inhalers. Furthermore, propylene glycol is a primary ingredient in the ‘mist’ generated by fog machines at concerts and other staged events. In other words, the use of PG as a safe inhalant is a well-accepted practice, and it’s nothing new. At X2 Cigs, we use pharmaceutical-grade PG – and that’s an important consideration. Don’t settle for anything less.

Finally, PG is responsible for the so-called ‘throat hit’ that vaping produces. This slight burning sensation is similar to the sensation of smoking tobacco products. Some vapers claim that subtle parallels like this with smoking have made it easier for them to make the switch.

Vegetable Glycerine

Vegetable glycerine (VG) is another important ingredient in e-liquid. VG is derived from vegetable oil. It has a light sweet taste on its own and gives the vapour a sensation of ‘thickness’.

This natural compound is responsible for producing most of the vapour. With that in mind, VG contributes to the aesthetic qualities of vaping – i.e. the sense of inhaling and exhaling plumes of vapour.

This is an important ingredient, as it maintains the visual aspects of smoking – inhaling, exhaling and seeing a cloud of ‘smoke’. This helps some people who are hooked on cigarettes make the transition to vaping with fewer hang-ups, because the visual cues are still there.

VG has many applications in day-to-day products. It’s used to add moisture to baked goods as well as to create thickness (or viscosity) in medicinal creams, capsules and jellies. You’ll find it used as a thickening agent in a host of other products as well. Its safety as a food additive is widely accepted, and research also indicates that it’s safe to inhale.

As we mentioned above, this natural product is excellent at producing vapour. In fact, the only reason that propylene glycol is even added to the mix is because VG doesn’t carry added flavourings (or nicotine) very well. That said, some e-liquid producers create VG-only juice, mainly for marketing purposes.

A more practical reason to create e-liquid with a higher-than-usual VG content is for cloud-chasing purposes. Drip-mod enthusiasts will seek out high-VG e-liquid for the volume of vapour that it produces.

Flavouring

As we mentioned above, flavouring is suspended in the PG in order to create the various flavours that are available. These are often similar to the flavourings added to food – but only in function. As in previous cases, flavouring that is safe to ingest is not necessarily safe to inhale.

Along those lines, the flavourings that are used for vaping are specifically designed to be safe to inhale. The flavourings that X2 use have been rigorously tested to ensure that they provide a rich and flavourful vape without posing any risk to the vaper’s health.

Take a look at the range of e-juice flavours available on our website, and you’ll see that it’s possible to create many different flavour profiles, indeed. To give you an idea, here’s a sampling of the flavours available in our shop:

• Black cherry
• Turkish blend
• Banana
• Cinnamon
• RY4 (i.e. tobacco with a hint of caramel)
• Cappuccino
• Apple
• Vanilla
• Coconut

And that’s only the beginning. We’ve supply many more flavours and flavour-combinations for you to enjoy beyond those listed above.

Nicotine

As with the flavouring, nicotine is also suspended in the propylene glycol found in e-liquid. We insist on using only the purest, natural nicotine available – ensuring that X2 e-liquids are of the highest quality.

The amount of nicotine that is found in a sample of e-liquid varies, and of course those that are nicotine-free don’t contain any of this ingredient. Thanks to our easy-to-use online interface, you can customise the amount of nicotine that appears in your e-liquid according to the following four categories:

• Zero: This is suitable for those who love the pleasures of vaping but have no need for the nicotine.

• Light: With 6 mg of nicotine, e-liquid at this level is useful for stepping down the nicotine level to near-zero; it’s also useful for an all-day vape that you want to enjoy repeatedly without high nicotine exposure.

• Medium: This level of e-liquid contains 12 mg of nicotine and is better-suited to those who appreciate the effects of nicotine as well as a flavourful vape.

• Full-Flavour: Our strongest e-liquid contains 18 mg of nicotine and is suitable for those making the switch from smoking to vaping as well as those who appreciate the throat hit associated with higher nicotine levels.

If you’re taking up vaping in order to quit smoking, then it’s best to gradually step down the nicotine level of your vape until you reach zero. And should you have any other questions about the ingredients we use in our e-liquids, feel free to contact us.
