Top E-Liquids that Are Tested For Safety

Diacetyl Free, Acetyl Propionyl Free E-Liquids, Independently Tested For Safety  

If you're looking for vape juice brands that have been safety-tested to be free of potentially dangerous chemicals, check out our chart, shown below. We've researched the top vape companies, so you know where to buy e-liquids that are free of diacetyl and acetyl propionyl.  All e-liquids never contain vitamin E oil, either!


Diacetyl –  (pronounced die-AS-a-til) is found naturally, in foods such as butter and beer. It is a chemical by-product of fermentation.

Some e-liquids can contain small amounts of diacetyl, as it creates a buttery, creamy or custard taste.

The diacetyl scare began years ago. A few workers in microwave popcorn factories contracted a rare respiratory illness called “bronchiolitis obliterans”. In studying the cause of the disease, researchers found that the workers were exposed to large quantities of airborne particles containing diacetyl. It was determined that in these production settings, the inhalation of diacetyl could be dangerous. 

Although the risks have been shown to be far lower for vapers inhaling e-juices with diacetyl, the potential consequences of extended diacetyl inhalation are still unknown. As a result, many e-liquid companies have removed diacetyl from their formulas.

Here is the Dr. Farsalinos Report on Diacetyl


ACETYL PROPIONYL is an organic compound used as an artificial flavor in many foods. AP is also used in e-liquids to lend a sweet, caramel, and/or fruity flavor.

There is some controversy surrounding the use of this substance in vapor products, although there is, to date, no concrete evidence that it is harmful to humans.

Until further research emerges, many responsible e-liquid brands, such as those listed below, choose not to use acetyl propionyl in any flavors.

We want you to be informed, which is why our team members contacted the most popular e-liquid companies to learn whether they are testing and revising their e-juice ingredients to exclude diacetyl and acetyl propionyl.

    Hi, I am enjoying Eclipse by Space Jam. Recently, I saw somewhere that Space Jam juices contain Diacytile. I wanted to go through their website, which I found not working.

    Is it safe to use Eclipse? Thanks

    1. Hi Miska,

      DirectVapor is still selling Space Jam although today they are saying it is currently out of stock. Space Jam does NOT contain Diacetyl!
      Thanks for the visit!

    Hi, I’m currently using I Love Salts liquid, fruity flavor won’t have Diacetyl in it, right??

    1. Hi Ethan,

      Sorry I’m not familiar with that brand. I suggest you contact the company’s customer service department. Good luck!

    Which of those liquids listed is best for pod mods like Suorin Air or Suorin Pod? If all of these are too thick, any suggestion on how to get the liquid thin enough to work in a mod pod?

    1. Hi John,

      Any of them are fine! Just make sure you choose the company’s regular e-liquids – not high VG or those made for subohm vaping. Even CBD vape juice will work because they usually do not use high VG blends. Happy vaping and thanks for your comment.
