| Comments |
In animals: irritation of eyes, skin, and nose; corneal necrosis; weight loss; [NIOSH] Molten substance may cause severe burns; [CAMEO] May be corrosive to skin and eyes based on animal results; [CHEMINFO] DBAE is an irritant of the nose and ieys. Animal studies show that DBAE inhibits acetylcholinesterase. The median lethal dose in rats dying of respiratory arrest is 89.1 mg/kg. Five rats with inhalation exposures of 33 ppm 6 hours a day for 5 days had no mortality. [ACGIH] |
