Results and discussion
Effect levels
- Key result
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 5 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- No mortality occurred.
- Clinical signs:
- No systemic clinical signs were observed during clinical examination.
- Body weight:
- The mean body weight of the male animals increased within the normal range throughout the study period. The mean body weight of the female animals only slightly increased during the first post-exposure observation week, probably due to the bandage procedure, but increased during the second week within the normal range.
- Gross pathology:
- No macroscopic pathologic abnormalities were noted in the animals (5 males and 5 females) examined on the last day of observation.
- Other findings:
- No local effects were observed.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
