Everything you need to know about e-liquid

Why Evo Juice?

There have been many articles and discussions about the general safety of e-liquid.

E-liquid could be made up of an array of different ingredients. Not all suppliers/manufacturers use the same ingredients, and some may not be all that safe to inhale.

So yes! Knowing what is in the e-liquid you’re vaping is super important!

What ingredients are used in your every day e-liquid?


Nicotine is what we are all addicted to, it’s what keeps us coming back for more. Nicotine stimulates the central nervous system and raises blood pressure, respiration and elevates the heart rate. The great thing about Vaping is, Nicotine is not a vital ingredient in e-liquid and can be left out… if your lungs desire. Nicotine is added for the people wanting to switch from traditional cigarettes to vaping for that sense of nicotine satisfaction, without the harmful chemicals and “bells and whistles” in traditional cigarettes.

Propylene Glycol (PG)

PG is a lab-made liquid that is odourless and tasteless, this is the better flavour carrier of your e-liquid and provides the throat hit, which the FDA (Food and Drug Administration) “generally recognises as safe” in food. It is also used in artificial smoke and fog machines for entertainment.  PG has been used in many different combinations for different uses; from hospitals to ice-cream. On its own, the risk of PG is minimal to non-existent. A study published in Journal of Pharmacology confirmed that since 1947 PG is not dangerous when orally inhaled.

An interesting find in the study was that PG may also be a powerful deterrent against pneumonia, influenza and other respiratory diseases when vaporised and inhaled.

Vegetable Glycerin (VG)

VG is a slightly sweeter and thicker liquid (compared to PG).  Also known as glycerol, VG is the component of the e-liquid that provides the plumes of clouds! The larger VG content normally results in a larger cloud volume. VG is a clear odourless liquid that is made of plant oils used in many ways, including cosmetic products and lotions, making it not only safe to your skin and body but also safe to consume.

The SIDS initial assessment profile of PG confirms its safety in a variety of applications and also states that it has low toxicity levels for consumption, topical contact, and inhalation.


Flavour, Flavour, Flavour. This is what it’s all about! Flavour is the most complex variable of the e-liquid ingredients. The word “flavouring” is sometimes all that is used to describe an ingredient, leaving one with a lot of questions, such as; if they are safe for consumption, are they, in fact, safe for inhalation? You want to stay clear of known additives like “Diacetyl, Acetyl Propionyl and Acetoin.”


While it is not necessarily bad for you if consumed, some ingredients used in flavouring can be potentially dangerous once inhaled. An example of this is “diacetyl”. Diacetyl is the flavouring composition used to create creamy buttery flavours. Although not being dangerous when consumed orally, a lot of factory workers in a popcorn factory experienced health problems and lung disease in response to inhaling the flavouring substance through their workday, causing the dreaded disease known as “popcorn lung”.

The diacetyl amounts that have been reported in many of the popular e-liquids are well above the safety limit that has been set by OSHA. Even the amounts shown as “trace amounts” in juices are well above the suggested exposure quantities.

Edit: Although traces of diacetyl have been found in some e-liquids and might not be as harmful as the media made it out to be, it is not nearly as much as the amount found in traditional cigarettes.

According to Dr. Michael Siegel, professor in the Department of Community Health Sciences at Boston University School of Public Health, the Harvard study has several “glaring omissions,” and the level of diacetyl exposure from vaping compared with smoking differs by “orders of magnitude.”


Siegel points out the study published in the journal “Environmental Health Perspectives” didn’t even mention that regular cigarettes contain diacetyl, and in far greater amounts than any e-liquids.

Looking at the numbers, Siegel found “daily exposure to diacetyl from smoking is therefore 750 times higher, on average than exposure to diacetyl from vaping.” Vapers are, on average, exposed to a daily dose of nine micrograms of diacetyl, compared with 6,718 micrograms for smokers.

But vapers have little reason to worry about the trivial levels of diacetyl in e-liquid compared to traditional cigarettes.

Not only is the risk of diacetyl exposure far lower for vapers than for smokers, but according to Critical Reviews in Toxicology, “smoking has not been shown to be a risk factor for bronchiolitis (popcorn lung).”

Acetyl Propionyl and Acetoin

Acetyl Propionyl and Acetoin are the substitutes that arrived after the initial scare of Diacetyl and research suggests that these chemicals also can contain or convert themselves to Diacetyl.  These were used to be safer alternatives to Diacetyl, but they are still considered to be potentially harmful. These two chemicals are still considered lung irritants and their chemical composition is very similar to Diacetyl.


Although it may not bad for you when inhaled. Several studies done proved that people vaping e-liquids containing alcohol ingested enough alcohol via the e-cigarettes that metabolised booze was detected in their urine.

Dr Mehmet Sofuoglu, professor, Yale School of Medicine said the findings are “worrisome,” particularly on the heels of new data showing a dramatic upward spike in the number of middle school and high school students using e-cigarettes.

Sofuoglu said the study showed how e-cigarette users, even if they didn’t end up having enough detectable alcohol in their urine to trigger a DUI charge, could end up being “intoxicated” and too impaired to drive because of how much “more quickly and efficiently” alcohol affected the brain after people inhaled vaporized booze compared to drinking it.

E-cigarette vapers who use liquids high in alcohol content may be on the track to “a faster level of dependence” on both alcohol and nicotine, Sofuoglu said.

What is Vaper’s tongue? – And how to fix it!

Vaper's tongue - what it is and how to fix it

Have you ever had a moment when you have been vaping your favourite flavour e-juice and then all of a sudden just can’t taste it anymore? Or found that your tongue is a bit numb?

Vaper’s tongue happens to most of us. There’s nothing wrong with your tongue or taste buds, to start off with, so you don’t have to worry. Another, probably better, term to use is “flavour fatigue”.

Try to remember that vaper’s tongue is totally unpredictable. There are those who have been vaping for years and never experienced it, while someone new to vaping might feel the effects of flavour fatigue just days or weeks after switching to e-cigarettes.

Before you get too worried, you should know that it is not a medical or serious issue at all – there are some simple explanations as to why this could happen:

1. Quit Smoking

New vapers who recently stopped smoking cigarettes are prime candidates for vaper’s tongue. As we all probably know, smoking dulls your sense of taste, so when you start vaping your senses can get overwhelmed by the intensity of flavours, causing your taste buds to want to take a break for a while. This can happen several times as your body transitions to being a non-smoker.

2. Damaged taste buds

Eating a lot of spicy foods, smoking, infections, alcohol, extremely sour foods and some medications can damage your taste buds resulting in you not tasting your e-juice.

3. Dehydration

The process of vaping might dehydrate you. The solutions in e-liquid (PG or VG) attract and draw out moisture, which means not drinking enough water while vaping can dry out your mouth and a thin film could form on your tongue which acts like a shield that blocks flavoured e-liquid from reaching your taste buds.

4. Not Enough Variety

Everyone has their favourite flavour they want to vape all the time! However, too much of the same flavour can make your taste buds less sensitive to that particular flavour. Try mixing some new flavours here.

5. Colds or Allergies

When you get sick, often the first thing you lose is your sense of smell, which affects your taste buds. Having a cold or sinus issues make it almost impossible to taste anything – e-liquid flavours included.

6. Stress and anxiety

Anxiety can also cause tastes to change. And, strangely, you can experience changes in taste even when you do not think you are suffering from anxiety at the moment.

While we don’t know all the reasons why taste buds change when you are stressed, some causes include: breathing through your mouth – when you are suffering from anxiety, you tend to breathe through your mouth, which can lead to different tastes (possibly because it affects your salivary glands and the bacteria in your mouth) or acid reflux.

7. Aging E-liquid

As e-liquids age, flavours can degrade, sometimes leading to a peppery taste. In which case, you might not have a case of vaper’s tongue at all, but simply need to get some new e-juice!



1. Change your flavour

Simply change the flavour you are vaping, and return to your old flavour after a couple of weeks. Hopefully, it will then taste just as good as it used to!

2. Use a stronger flavour

It may also be an idea to abandon the more subtle vaping flavours, and use something a bit more down to earth and strong.

3. Drink water

Drinking water addresses two potential problems of vaping: it clears the palette, and also helps to rehydrate you.

4. Inhaling the smell of fresh coffee beans or sucking on a lemon

This is a technique used by professional wine tasters and perfume samplers. While I bet most of us has no idea how it works, these experts believe that inhaling the scent of fresh coffee beans “resets” your senses.
A number of vapers have mentioned this has been a solution for their vaper’s tongue, so why not?!

Like coffee beans, sucking on a lemon is supposed to reset your taste buds and palette as well.

5. Allow time

Damaged taste buds can take up to two weeks to recover. So give it a little time and you may find your tongue is back to normal!

Cresta Grand Opening

The Evolution Vape Team

Saturday morning, 1 April 2017, was the Grand Opening of our brand new store at Cresta Shopping Centre and it was no April fools joke. A line filled with eager customers greeted us in the early hours of the morning, we were more than ready to swing open our doors and welcome them all into our brand new store! First through our doors were Brendan, Justin and Wyne. Brendan, who waited for our Grand Opening since 1am that morning, was the first customer to set foot in our new store. His patience and support finally paid off when we handed him the impressive SMOK Alien bundle to the value of R1999!! Justin and Wyne each received a free Kangertech Subvod bundle (to the value of R799 each) and got to blend their own flavours at our Juice Bar. With over 20 flavours to choose from, you can also tailor your own flavours here.

Following our “Grand Opening first to enter” trio were Cheyenne, Justin, George and Greg Mungofa, who also received free Kangertech Subvod bundles! Not only did we have our Grand Cresta Opening, but we also launched our brand new flavour range: The Grand Reserve Range. It turned out a huge success with the employees and clients complimenting the sweet and creamy taste of the flavours. You can get them exclusive to our Cresta store! Overall the Grand Opening was a massive success and we are ever grateful to have so many loyal customers supporting us!
