Results and discussion
Effect levels
- Key result
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- 1 300 mg/kg bw
- Based on:
- act. ingr.
- Mortality:
- Motaliity was not affected.
- Clinical signs:
- other: A high incidence of diarrhea was noted with the use of the higher concentration. Those rats which succumbed appeared to be weak and showed reduced voluntary activity prior to death.
- Gross pathology:
- No significant gross abnormalities were seen at autopsy.
Applicant's summary and conclusion
- Interpretation of results:
- Category 4 based on GHS criteria
- Conclusions:
- The acute oral LD50 in male/female rats is 1300 mg/kg bw. No significant gross abnormalities were seen at autopsy.
LD50-rat 1.8 mL/kg ⇔ 1.3 g a.i./kg = 1300 mg/kg bw - Executive summary:
The acute oral LD50 in male/female rats is 1300 mg/kg bw. No significant gross abnormalities were seen at autopsy.
LD50-rat 1.8 mL/kg ⇔ 1.3 g a.i./kg = 1300 mg/kg bw
