Conclusions:

Inhalation toxicity (LC50 value) of 2-(2-ethoxyethoxy)ethyl acetate vapours was examined for 4 hrs.in male Webster mouse at a dose concentration of 568.9634 mg/L.

Executive summary:

Inhalation toxicity (LC50 value) of 2-(2-ethoxyethoxy)ethyl acetate vapours was examined for 4 hrs.in male Webster mouse at a dose concentration of 568.9634 mg/L. This value suggests that the chemical 2-(2-ethoxyethoxy)ethyl acetate is non toxic to mouse by the inhalation route.
