What is Diacetyl?

Diacetyl is an artificial flavoring ingredient which is commonly used in food products and naturally occurs in many types of alcohol. Diacetyl has a buttery flavor, and is commonly added to oil based butter substitutes, and microwave popcorn.
Studies in recent years have shown that exposure to the vapor created when diacetyl is heated can increase the risk of bronchiolitis obliterans which is a very serious lung disease.
Due to the risks associated with the use of Diacetyl containing flavoring ingredients we ensure that all flavorings used in our premium e-liquids are free of this potentially harmful chemical.
