It’s all good and well knowing the different flavors and brands of e-liquids that are available to you as an vape user, though it’s also important that you’re aware of the ingredients used within those products.
Whilst it’s commonly true that vaping is less harmful than smoking tobacco, there are still some concerns regarding the chemicals that are used in the production of some of the e-juices – notably the use of diketones.
What Ingredients Are In My E-Liquid?
As many experienced vapers will know, there are hundreds of different flavor combinations to choose from across many different vaping brands. Because there are so many different preferences, the ingredients within your e-liquids will vary.
Mainly, your e-liquids will contain PG (propylene glycol) and VG (vegetable glycerin). PG is a nontoxic flavoring addictive, whilst VG is a vegetable based liquid that’s also nontoxic and works to sweeten flavoring.
A large percentage of e-juices will have a combination of both PG and VG, which is known as the PG/VG ratio, as it makes for a smoother vaping experience.
However, it’s also important to note that some companies will make use of diketones within their e-juices for additional flavoring, and these are chemicals that have been known to have further health risks and complications when used excessively.
What Exactly Are Diketones?
Diketones are chemicals that are found throughout the flavoring industry, so they’re commonly used in various e-liquids due to the flavoring properties that they offer. Instead of being a single chemical, diketones are actually a group of chemicals made up of mainly acetoin, propionyl, diacetyl, and acetyl.
Diketones are often used in food products such as creams or icings and these products are required by law to be tested for any harmful effects the chemicals may have. However, inhalation products, such as the different e-juices that you’ll find online, don’t need to be tested for diketones so you can’t always be certain what exactly your juice contains.
Are Diketones Harmful?
When it comes to the chemicals of acetyl, acetoin, and propionyl, there’s not much major call for concern due to the lack of scientific evidence indicated that they’re actually harmful. Whilst it’s been indicated that these chemicals can catalyze traces of diacetyl, there haven’t been enough studies to rule the chemicals as unsafe.
Out of the diketones, the main chemical you should be wary of is diacetyl. This is because it’s been found that the inhalation of a large amount of diacetyl can cause bronchiolitis, which was discovered after a notable amount of factory workers in the 1990s inhaled large quantities of the substance.
Whilst diacetyl obviously isn’t as present in e-juices as it was in a factory environment, it’s still proven to be a harmful chemical that can cause health effects and increase the likelihood of lung issues when it’s inhaled.
How Can I Avoid Diacetyl?
If you were to smoke tobacco, you would be inhaling about 750 times the amount of diacetyl than you do when vaping e-juice, so you’ve already reduced your exposure by vaping instead of smoking.
However, due to the controversy of the use of the chemical, many e-liquid suppliers and manufacturers have played it safe and have stopped using diacetyl in their products.
Whilst diacetyl is the main chemical that can cause lung and health issues, other diketones haven’t yet proved to be of much risk. Therefore, when purchasing any e-liquid – especially from a new brand – be sure to keep an out for diacetyl.
