Results and discussion
Effect levels
- Sex:
- female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Remarks on result:
- other: According to OECD 423, the LD50 cut-off is set at 5000 mg/kg bw based on a limit test with 2000 mg/kg bw, since no mortality occurred in any step.
- Mortality:
- No mortality occurred during the study period.
- Clinical signs:
- A hunched posture was observed in 6/6 rats 2 h after dosing. 3/6 animals had piloerection and the remaining 3/6 rats had slight uncoordinated movements from dosing until 4 h after administration. Slight alopecia was noted 2/6 animals from Day 9 or 10 until the end of the study period.
- Body weight:
- No effect on body weight was noted.
- Gross pathology:
- No substance-related findings were noted during macroscopic post mortem examination.
