What are the health effects of propylene glycol?
Ingestion of propylene glycol could cause irritation, burning sensations to the throat and mouth, nausea and vomiting. The side effects of prolonged inhalation of propylene glycol found in room deodorizers can cause irritation of the mucous membranes, wheezing, coughing and shortness of breath.
Is propylene glycol harmful?
According to the US Food and Drug Administration (FDA), propylene glycol is generally regarded as safe (GRAS), for use as an additive under certain specified conditions. However, workplace exposure to high concentrations and prolonged exposure to low amounts of propylene glycol may lead to minor allergic symptoms as well as severe health problems.
