Results and discussion
Effect levels
- Key result
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- No mortality occured during the study period.
- Clinical signs:
- No clinical signs of toxicity were observed up to the end of the 14-day observation period.
- Body weight:
- Body weight gains were within the normal ranges in females during the whole study period.
- Gross pathology:
- Necropsy examination revealed no substance-related findings. Small testes and epididymides was observed in 1/5 male. This was an incidental finding and not considered to be test substance-related.
- Other findings:
- Erythema grade 1 was observed in 4/5 female animals and desquamation was observed in 1/5 female animals on study day 2. All signs of irritation were were reversible within 3 study days.
