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

If you're looking for e-liquid brands that have been safety tested to be free of chemicals that may be harmful to your health, check out our chart. We've researched the top ejuice companies and show where to buy diacetyl and acetyl propionyl free e-liquids.

WHAT IS DIACETYL? 

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

Inhalation of large quantities of airborn particles containing Diacetyl in production settings (including microwave popcorn factories) have been linked to a rare respiratory illness – bronchiolitis obliterans.

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

WHAT IS ACETYL PROPIONYL?

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, creamy, buttery, 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 for their sweet,creamy, custardy 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 ejuice ingredients to exclude diacetyl and acetyl propionyl.
