What is diacetyl and is it safe, Smoking e-cigarettes?
Diacetyl is a chemical flavoring agent, which is used by many e-cigarette oil manufacturers in sweetened e-cigarette oils such as candy, fruit- and cake flavors are used. This chemical is commonly used in microwave popcorn, to achieve a sweet buttery taste.
Among the employees of several factories, make the margarine flavors, was diagnosed with occlusion bronchitis, a severe lung disease, which is commonly called “Popcorn worker's lung” is known, since it first appeared with a former worker at a microwave popcorn factory in the USA. Das National Institute for Occupational Safety and Health (NIOSH) has therefore pointed this out, that prolonged heating and inhalation of diacetyl can be harmful.
Cases of this respiratory disease have been reported in young people, healthy, non-smoking men.
“I agree though, that we should know, whether e-cigarette oils contain diacetyl and acetylpropionyl, but I have to point this out, that this study leaves out some very important points. One is this, to evaluate the values found in their samples”, said cardiologist and e-cigarette researcher Dr. Farsalinos.
According to Farsalinos, the diacetyl levels are “absolutely minimal and do not raise any concerns about the impact on human health”. Farsalinos also noted in his blog, that the authors of the study “did not mention the presence of these compounds in cigarette smoke”.
Diacetyl was in 39 of the tested perfumes were found to be above the detection limit in the laboratory. Ethylene coupling and 2,3-pentanedione were in 46 or. 23 Perfumes detected.
This worrying issue is not entirely new to e-cigarette users. In a publication from the year 2014 was determined, that diacetyl is present in many samples of sweetened e-cigarette liquids, albeit in a concentration 100 times lower than tobacco smoke. The study concluded, that diacetyl “poses an avoidable risk to e-liquids and that the industry could take action, to prevent its use, without restricting the availability of flavors”.
