Comments |
In the body, methyl acetate is hydrolyzed into methanol and acetic acid. It causes narcosis in animals exposed to high concentrations. [ACGIH] Ethyl acetate is in the list of "Some volatile substances which may be abused by inhalation" published on the web site of the U.N. International Drug Control Programme, indicating its potential to cause narcosis in workers. [Reference #1] An eye and respiratory tract irritant; Inhalation of high concentrations can cause CNS depression; [ICSC] |
