Q. What is Eliquid?
A. Eliquid is the solution used in an electronic cigarette to produce its vapour, flavour, and in some cases “throat hit” (Throat hit is a term used to describe the bite in your throat produced by nicotine eliquid vapour.)
Q. What Ingredients are in Eliquid?
A. Eliquid recipes vary from one company to the next however all contain the same types of ingredients.
Eliquid starts with a base, which is the part used to create the vapour produced. The base of an eliquid is made from a mixture of propylene glycol, and vegetable glycerin.
Water soluble, natural and artificial flavouring ingredients are added to the eliquid base to create the variety of flavours we offer.
Some eliquids may also contain small amounts of food grade alcohol, and or distilled water.
Q. What is Propylene Glycol?
A. Propylene Glycol is a food grade chemical used in a large number of applications as an additive in cosmetic, medicine, and food products.
Propylene glycol is used in many food products as a flavouring carrier. Propylene glycol is non toxic, and is also found in many food products including food colourings, flavourings, and snow cones.
Propylene glycol has a slight irritating effect when inhaled. This effect is used to better mimic the irritation caused by inhaling tobacco smoke.
Please Note: Some individuals are allergic, or intolerant to propylene glycol. Common indications of a reaction to propylene glycol may be a warm, tingly, or burning sensation in your mouth or tongue. If you experience any side effects of this sort we advise that you speak to a medical professional or try a predominantly vegetable glycerin based e-liquid.
Q. What is Vegetable Glycerin?
A. Vegetable Glycerin is similar to propylene glycol, although thicker, and with a sweeter taste. Vegetable glycerin is also much smoother when inhaled than propylene glycol.
When used on its own, Vegetable Glycerin is very thick, and often difficult to absorb into your cartridge, or cartomizer.
Please Note: Some individuals are allergic, or intolerant to vegetable glycerin. Common indications of a reaction to vegetable glycerin may include a heavy feeling of phlegm, or liquid buildup in your lungs, or irritation in your throat, lungs or mouth. If you experience any side effects of this sort we advise that you speak to a medical professional or try a predominantly propylene glycol based e-liquid.
Q. How Much Propylene Glycol & Glycerin are in Flavour Crafters E-liquids?
A. Our commercial blend contains roughly 70% food grade propylene glycol, and 30% vegetable glycerin. This ratio is the best choice for the average user, it has an excellent throat hit while still maintaining a smoothness and vapour production lacking in glycerin eliquids.
Our commercial 70/30 blend of pg and vg is works exceptionally well in most tank, cartomizers, and atomizers devices without any of the wicking problems experienced with most vg based eliquids.
70/30 eliquid blends are generally preferable for individuals with slight intolerance to vegetable glycerin.
Our new reduced PG e-liquid line contains under 20% propylene glycol, and 70% vegetable glycerin. Unlike most predominantly vegetable glycerin eliquids which are too thick to properly vape, we've thinned the consistency of our 70% VG line to ensure it functions properly in your devices.
Our 70% VG eliquid line is our recommendation for anyone who would prefer a mostly vg eliquid.
Q. What is Diacetyl?
A. Diacetyl is an artificial flavouring ingredient which is commonly used in food products and naturally occurs in many types of alcohol. Diacetyl has a buttery flavour, and is commonly added to oil based butter substitutes, and microwave popcorn.
Studies in recent years have shown that exposure to the vapor created when diacetyl is heated can increase the risk of bronchiolitis obliterans which is a very serious lung disease.
Due to the risks associated with the use of Diacetyl containing flavouring ingredients we ensure that all flavourings used in our premium eliquids are free of this potentially harmful chemical.
Q. What is Acetoin?
A. Acetoin is a flavouring ingredient similar to diacetyl which is used in the food industry to create a buttery flavour. Studies have shown that Acetoin can under certain circumstances react with other flavouring ingredients or chemicals to create diacetyl traces. Due to this we ensure that our flavours are free of Acetoin, as well as Diacetyl.

PG (Propylene Glycol) vs. VG (Vegetable Glycerin)
When it comes to e-juice, two terms constantly crop up: PG and VG. This can seem confusing to the newcomer, but knowledge of these two ingredients can vastly improve your vaping experience. Here’s our easy-to-follow guide on everything you need to know about PG and VG.
What are PG and VG?
In simple terms:
Choosing the wrong PG/VG ratio can put first-timers off so be careful to choose the right level for your equipment.
Now let’s take a look at each in more detail.
PG and VG are the odourless liquids that are combined with flavour and nicotine to create e-juice
Both PG and VG belong to the alcohol chemical class (despite the name, they are not intoxicating). Though e-liquid is sometimes called “oil,” it isn’t really oil at all, and can’t cause any of the medical issues — like lipoid pneumonia — that inhaling actual oils can.
They produce vapour when heated, which allow them to be inhaled.
The two fluids have a different consistency to each other, and also have a slightly different taste.
They have distinct mouth and throat sensations when vaped.
Most modern e-liquid uses a combination of the two fluids, though the ratio can vary dramatically.
Some vaping set-ups can only work with a certain level of PG and VG.
PROPYLENE GLYCOL (PG)
What exactly is it?
Propylene Glycol Chemical Structure
PG stands for Propylene Glycol, a petroleum by-product. The fluid has no odour or colour, and is less viscous than VG. In vaping it is used to provide a ‘throat hit’, which some users claim is similar to the sensation experienced when smoking tobacco. It also carries flavour more effectively than VG, meaning it’s the most commonly used suspension fluid for flavour concentrates and nicotine.
How is it used?
Propylene Glycol can be found in various common household items. Amongst others, these include:
Toothpaste and other oral hygiene products
Medical products used orally, injected or as topical formulations
Beauty products, including make-up, shampoo and baby wipes
Is it safe?
Studies have shown that PG is safe to ingest orally, and the FDA has deemed it “generally recognized as safe” to be used as a food additive. However, most studies into the safety of propylene glycol look at ingestion, rather than consuming it in aerosol form. Of the limited studies that exist, a long-term experiment held in 1947 judged that inhaling PG was ‘completely harmless’.
A 2010 study looking at PGEs (a mixture of propylene glycol and glycol ethers) suggested an increased risk of developing respiratory and immune disorders in children, such as asthma, hay fever and eczema. However, it was judged that glycol ethers, and not PG, are the more likely cause. Looking at the evidence, it is sensible to assume that PG is safe to be inhaled, but there is a need for more comprehensive studies to confirm this.
Many misinformed scaremongering stories in the media claim that PG is a toxic substance used in anti-freeze. However, there are two types of anti-freeze: toxic and “non-toxic”. The toxic anti-freeze uses the dangerous substance referred to as actually ethylene glycol, but it is not used in vaping. Typically PG-based anti-freeze is used in food-processing machinery where toxic anti-freeze could be problematic, and is also sold at retail as “pet-safe” anti-freeze.
While PG is regarded as safe for humans, it can cause serious harm to pets. It is generally regarded as safe as a food additive for dogs, but has been linked to Heinz body anaemia in cats. Be careful when vaping around pets, particularly if you have cats and use PG in your e-liquid.
What should I be aware of when vaping PG?
Some people find a high level of PG irritating to the throat. True allergies to PG are rare, but have been reported. If you find yourself coming out in a rash, or suffering other unpleasant reactions after using PG-based e-fluid, you may have a more common mild sensitivity to PG, and should look at using high-VG juice instead. Many vendors offer this option.
The most common side effects of using e-liquid containing propylene glycol are dry mouth, sore throat, and increased thirst. These symptoms usually last anywhere from a few days to a week as the body gets used to the propylene glycol. It is advised to drink more water and liquids then usual for the first few weeks of using your e-cigarette. Be aware that any unusual reactions could be side effects from quitting smoking, and not necessarily because of the PG.
VEGETABLE GLYCERIN (VG)
What exactly is it?
VG stands for Vegetable Glycerin. It is a natural chemical, derived from vegetable oil, so is safe for vegetarians. It is commonly used in e-liquid to give a ‘thick’ sensation to vapour. VG has a slightly sweet taste and is considerably thicker than PG. The hit from a high VG fluid is a lot smoother than with PG, making it more suitable for sub-ohm vaping. While nicotine and flavourings are commonly suspended in PG, some vendors are offering a VG alternative, to enable 100% VG mixes.
What is it used for?
Again, it can be found in numerous medical, food and personal care products:
Sweetener as sugar replacement
Beauty products, such as make-up, mousse, bubble bath, aftershave, and deodorant
Soap and hand cream
Food such as baked goods, to increase moisture
To provide thick gel for certain medicinal creams, capsule pills and jellies
Toothpaste and other dental care products
Is it safe?
The FDA has classified VG as “generally recognized as safe” and it is widely regarded as one of the most benign substances known to man. The SIDS assessment profile show it to have low toxicity when consumed, and of low potential to irritate the skin or eye. This, along with the widespread use of VG in food and medicine suggest it is safe for humans. However, as with PG, there are limited studies on VG being inhaled as opposed to ingestion.
A 2008 study of the toxicity of inhaling aerosolised glycerol found minimal risks. We can assume the use of VG in vaping has no serious impact on health but, as with PG, we would welcome more detailed studies.
It is important to note that the risk of being allergic to vegetable glycerin is very low, making it a useful alternative for people who have issues when vaping e-juice containing PG. If you are allergic to palm oil or coconut oil then VG could prove a problem, but this is relatively uncommon. Diabetics could possibly experience problems with metabolising VG, but this would not be an issue at the levels used in vaping.
What should I be aware of when using VG?
The increased thickness of VG means it can reduce the life of atomizers quicker than PG-based juice. High VG liquids clog up coils more rapidly, and will not work well, if at all, in certain tanks. Older products are especially susceptible, particularly models that use smaller coils such as clearomizers. The Nautilus range, Innokin iclears and eGo tanks are some of the more well-known tanks that are known to have difficulties dealing with high VG fluid.
The most common side effect of vaping high VG e-liquid is a dry mouth, sore throat, and increased thirst. Again, be sure to drink plenty of water and take a break from vaping if necessary.
What PG/VG ratio should I use?
There isn’t a one-size-fits-all answer to this. It depends on the kind of vaping experience you prefer. Many people use various levels of PG and VG for different purposes:
Throat Hit – If you enjoy a sharp throat hit when vaping then you’ll prefer a high PG vape. The ‘kick’ at the back of the throat, is something many ex-smokers crave, and PG (along with the nicotine) provides more of this than VG. PG carries flavour marginally better than VG, so the flavour will be slightly improved.
Smoothness – High VG fluid tends to give a much smoother feeling on the throat, with a more substantial ‘thicker’ mouthfeel. The flavour is slightly muted in VG fluids, but this can be countered by using more power to produce more vapour. Be careful to stay within the voltage/wattage limits of your atomiser, or you risk dry hits, or even damaging your equipment.
Stealth Vaping – If you want to keep your vaping lowkey in public then high PG is the way to go. Less vapour is produced when exhaled, making this ideal for the less ostentatious vaping enthusiast. However, you should always apply common sense. Vaping in certain places, such as waiting rooms and on public transport, is often outlawed and is simply bad manners. As vaping is relatively new, we have a duty to be aware of public opinion and behave responsibly.
Cloudchasing – Cloudchasing involves exhaling dense clouds of vapour, the thicker the better. There are even competitive events based around this activity, where the person producing the biggest clouds wins. If this appeals then high VG is the only option – the higher the better.
