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.
