Description

Colorless liquid with a faint, amine-like odor; [NIOSH]

Sources/Uses

Used as a curing agent for polyurethane foams and silicone resins; a conditioner for cellulose acetate filaments; a corrosion inhibitor in lubricants and hydraulic fluids; and in the synthesis of other organic compounds; [ACGIH]

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]
