Applicant's summary and conclusion
- Interpretation of results:
- Category 4 based on GHS criteria
- Conclusions:
- Based on the experimental data an oral LD50 of 1.6 mL/kg bw was calculated for males and females resulting in an LD50 of around 1300 mg/kg bw.
- Executive summary:
The acute toxicity of the test item was investigated (n= 3 males and females per dose group). Rats received single undiluted oral doses of the test item by oral intubation and were observed for 14 days thereafter. Clinical signs like lethargy, piloeerection, diuresis, diarrhea, increased salivation, and fine body tremor were observed shortly after dosing. These signs were later accompanied by ataxia at 1.6 and 2.5 mL/kg bw and by increased lacrimation at 2.5 mg/kg bw.
Death occured from within 21 to 70 hours of treatment. Autopsy revealed darkening of the liver and kidneys and injection of mesenteric blood vessels.
Recovery of survivors, as judged by external appearance and behaviour, was apparently complete within five days of treatment. Slightly depressed bodyweight gains were observed during the first week of observation, but returned to normal during the second week, compared with controls.
Terminal autopsy findings were normal.
Based on the experimental data an oral LD50 of 1.6 mL/kg bw was calculated for males and females resulting in an LD50 of around 1300 mg/kg bw.
