Results and discussion
Effect levels
- Sex:
- female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- The test item did not cause mortality at a dose level of 2000 mg/kg bw.
- Clinical signs:
- other: Clinical signs were observed in animals treated at 2000 mg/kg bw with the test item. These included decreased activity (1/6) and hunched back (3/6). All animals became symptom-free by the end of the observation period.
- Gross pathology:
- No macroscopic observations were seen in animals dosed at 2000 mg/kg and terminated on Day 14.
Applicant's summary and conclusion
- Interpretation of results:
- practically nontoxic
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Under the conditions of this study, the acute oral LD50 value of the test item was found to be above 2000 mg/kg bw in female RccHan:WIST rats.
