Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The acute oral median lethal dose (LD50) of the test item in the female Wistar strain rat was estimated to be greater than 2000 mg/kg body weight.
- Executive summary:
The study was performed to assess the acute toxicity of the test item following a single oral dose in the Wistar strain rat.
Following a sighting test at a dose level of 2000 mg/kg body weight in one fasted female animal, an additional four fasted female animals were given a single oral dose of the undiluted test item at a dose level of 2000 mg/kg body weight and followed with a 14-day observation period. Clinical signs and body weight development were monitored during the study. All animals were subjected to gross necropsy.
There were no unscheduled deaths and no signs of systemic toxicity. Based on historical data from the supplier for this strain, all animals showed expected gains in body weight over the observation period, except for one animal which showed an expected gain in body weight during the first week of the study but a slight body weight loss (-2.5%) during the second week. No abnormalities were noted at necropsy.
The acute oral median lethal dose (LD50) of the test item in the female Wistar strain rat was estimated to be greater than 2000 mg/kg body weight.
