Results and discussion
Effect levels
- Key result
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 5 010 - < 7 940 mg/kg bw
- Based on:
- test mat.
- Mortality:
- A female rabbit died at 7940mg/kg dose level on day 4.
- Clinical signs:
- other: Reduced appetite and activity and lethargy (three to five days in survivors), increasing weakness, collapse and death.
- Gross pathology:
- At necropsy there was slight lung congestion, liver discolouration, enlarged gall bladder and slight gastrointestinal inflammation. Surviving animals were sacrificed 14 days after dosing. The viscera appeared normal by macroscopic examination.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The rabbit acute dermal LD50 was reported to be > 5010 mg/kg (but <7940 mg/kg). The study was not compliant with GLP.
