Use
Crotonaldehyde causes severe irritation ofthe eyes, nose, lungs, and throat. Exposureto a concentration of 12 mg/m3 in air for10 minutes can cause burning of the lungsand throat in humans. The symptoms ofinhalation toxicity in rats were excitement,behavioral change, convulsion, and death.The same symptoms were observed whencrotonaldehyde was administered subcutaneously.LC50 value, inhalation (rats): 4000 mg/m3/30 minutesLD50 value, subcutaneous (rats): 140 mg/kgCrotonaldehyde is less toxic than acroleinor formaldehyde. The toxic symptoms, however,were similar to those of acrolein. Thecis-isomer of crotonaldehyde is mutagenic; itcaused cancer in test animals. Oral administrationof 2660 mg/kg for 2 years producedtumor in the liver in rats. Evidence of carcinogenicityin humans is not yet confirmed.
