Acrolein is a colorless to yellowish flammable liquid with a disagreeable, choking odor. The principal use of acrolein is as an intermediate in the synthesis of acrylic acid, which is used to make acrylates, and of DL-methionine, an essential amino acid used as an animal feed supplement. The most important direct use of acrolein is as a biocide: it is used as a herbicide and to control algae, aquatic weeds and mollusks in recirculating process water systems. Combustion of fuels represents a major source of emissions of acrolein to the atmosphere. No chronic studies of humans exposed to acrolein are available.
