Interpretation of results:

other: Not classified

Conclusions:

Acute inhalation toxicity dose (LC50) was considered to be >12 ppm (>12000 mg/m3), when rats were exposed with the given test chemical via inhalation route for 6 hours.

Executive summary:

Acute inhalation toxicity study was conducted by using test chemical in group of 10 Wistar rats at the concentration of 12 ppm for 6 hours of exposure. The exposures were at atmospheres nearly saturated with vapors of the alcohol. The generators were fritted-disk glass bubblers containing a measured amount of alcohol through which all air entering the chamber was passed.Observations were made for mortality, signs of toxic effect, and body weight changes.Gross necropsies were performed on the animals that died and at the end of the holding period.Dose reported is calculated from sample loss and airflow. No deaths were seen in the 6 hour vapor inhalation studies.Signs of systemic toxicity were not pronounced and consisted primarily of central nervous system depression. Local irritation was observed to a very less extent in all the test animals. This irritation involved the mucous membranes of the eyes, nose, throat, and respiratory passages and was manifest as blinking, lacrimation, preening, nasal discharge, salivation, gasping, and chewing movements. Therefore, the acute inhalation toxicity dose (LC50) was considered to be >12 ppm (>12000 mg/m3), when rats were exposed with test chemical via inhalation route for 6 hours.
