Is propylene glycol vapor safe for inhalation?
Propylene glycol (PG) is generally recognized as safe by oral, dermal or inhalation routes and has been a common ingredient in all American made tobacco cigarettes for seven decades (AAPHP website).
Is it safe to vape propylene glycol?
Yes – it’s used as a food additive in many, many products, so you probably already consume it on a daily basis. Is propylene glycol safe to vape? Yes, to be clear, it is considered extremely safe, non-toxic, and has no cancer-causing properties, unlike tobacco!
What happens if you inhale glycerin?
Vegetable glycerin toxicity Inhalation of vapors at high concentration may irritate the respiratory tract. Ingestion at high dose may cause nausea, vomiting and diarrhea. Glycerol is not judged toxic in contact with skin, eyes or if swallowed.
Does propylene glycol hurt your lungs?
Exposure to electronic cigarette vapors of propylene glycol and glycerol affects the expression of circadian molecular clock genes in the lungs despite causing no inflammation.
How does propylene glycol affect the body?
After ingesting a food containing propylene glycol, about 45% of it will be excreted by the kidneys unchanged. The rest is broken down in the body into lactic acid ( 1 , 14). When consumed in toxic quantities, the buildup of lactic acid can lead to acidosis and kidney failure.
Why is propylene glycol used in Vapes?
In vape juice, propylene glycol is used to generate a smoother smoke, as well as to contribute to the flavor.
What are the effects of inhaling propylene glycol?
Vaping propylene glycol and vegetable glycerine may lead to lung inflammation. Researchers have found that using e-cigarettes with the e-liquid refills containing propylene glycol (PG) and vegetable glycerine (VG) may lead to inflammation of the lungs over a period of time.
Are propylene glycol fumes toxic?
Oral exposure to the small amounts of propylene glycol found in foods and drugs is unlikely to cause toxic effects. Dermal exposure to propylene glycol, through cosmetics or drugs, or inhalation of synthetic smoke or mist, may be more frequently associated with reported reactions.
Is glycol toxic to breathe?
Breathing ethylene glycol vapors may irritate eyes and lungs but is unlikely to cause systemic toxicity. Ethylene glycol does not absorb well through the skin so systemic toxicity is unlikely. Eye exposure may lead to local adverse health effects but is unlikely to result in systemic toxicity.
What are the side effects of propylene glycol?
Although PG is generally considered safe, when used in high doses or for prolonged periods, PG toxicity can occur. Reported adverse effects from PG include central nervous system (CNS) toxicity, hyperosmolarity, hemolysis, cardiac arrhythmia, seizures, agitation, and lactic acidosis.
What happens if you inhale ethylene glycol?
Very high levels of inhaled ethylene glycol vapors can irritate the upper respiratory tract. Levels higher than 80 ppm produce intolerable respiratory discomfort and cough. Ethylene glycol’s CNS effects can cause respiratory depression, and metabolic acidosis can result in hyperventilation and respiratory alkalosis.
