Abstract
The draft Toxicological Review of Propionaldehyde provides scientific information on the effects pertaining to exposure to propionaldehyde.
Propionaldehyde is a colorless liquid with a suffocating, fruity odor. It is used in the manufacturing of propionic acid and polyvinyl and other plastics, in the synthesis of rubber chemicals, and as a disinfectant and preservative.
The chemical is released to the environment primarily through the combustion of wood, gasoline, diesel fuel, and polyethylene. Propionaldehyde is also a component of cigarette smoke and a food additive/flavoring agent. Although no studies on the effects of propionaldehyde administered by the oral route have been performed, based on its expected daily intake (below 1800 µg/day) and eventual metabolism in the citric acid cycle, it does not appear to be a safety concern for public health via ingestion (USFDA, WHO/JECFA). Thus, the most probable route of exposure of concern to the general population is by inhalation. The assessment will present reference values for the noncancer effects of propionaldehyde (RfD and RfC), where supported by available data, and a cancer assessment.
