Diacetyl can cause

When inhaled, diacetyl causes bronchiolitis obliterans – more commonly referred to as “popcorn lung” – a scarring of the tiny air sacs in the lungs resulting in the thickening and narrowing of the airways.

Can diacetyl cause lung problems?

Because this condition was first associated with diacetyl’s use in popcorn flavoring, it has become known as “popcorn lung” or “popcorn worker’s disease.” Diacetyl affects mainly the lungs, but it can also affect your eyes, nose, throat and skin. Symptoms can start gradually and worsen over time, or happen suddenly and be very severe.

Can diacetyl cause rash?

Eyes nose and throat– Diacetyl vapors can sting or burn the eyes. The vapors can cause your nose and throat to burn and feel sore. Skin — Diacetyl can aggravate the skin. It can cause a rash with dryness, redness, flaking and cracking of the skin.

Can diacetyl cause a chemical burn?

Symptoms can start gradually and worsen over time, or happen suddenly and be very severe. Exposure to diacetyl can cause your eyes to sting, and your nose and throat to burn. If the chemical comes in contact with your eyes, it can cause a chemical burn needing immediate medical attention.

Is diacetyl dangerous?

While consuming diacetyl is not a major health risk, inhaling diacetyl vapors is very dangerous. This poses a great threat to users of Juul and other e-cigarettes. Diacetyl vapor inhalation is linked to an array of pulmonary complications, including the popcorn lung.

Can diacetyl cause lung disease?

Also, chemical workers in a plant that manufactured diacetyl and coffee workers exposed to diacetyl developed the same type of lung disease as microwave popcorn workers (van Rooy et al. 2007 and 2009). The chemical workers had less complicated exposures than microwave popcorn workers.

Is it dangerous to inhale diacetyl?

However, inhaling diacetyl and similar flavorings — at least in large quantities, like the popcorn factory mixers did — can cause irreversible lung damage. Popcorn lung, or bronchiolitis obliterans, is famously caused by industrial diacetyl fumes, and acetyl propionyl is likely just as dangerous.

Can microwave popcorn cause lung disease?

Workers in microwave popcorn manufacturing are exposed to many materials besides diacetyl. Thus, NIOSH’s initial studies in a total of six microwave popcorn plants were not able to definitely determine if diacetyl exposure contributed to lung disease or was a marker for other hazardous substances that contributed to disease.

Can diacetyl cause bronchiolitis?

In longer 2-week inhalation studies in rats, researchers from the National Institute of Environmental Health Sciences (NIEHS) found that repeated exposures to either 2,3-pentanedione or diacetyl can cause airway fibrosis, including obliterative bronchiolitis-like changes, in rats ( Morgan et al. 2016 ).
