Results and discussion
Effect levels
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 5 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- No mortality occurred.
- Clinical signs:
- Following application, nine animals exhibited ano-genital staining but recovered from these symptoms by day 3. Aside from dermal irritation noted in one animal on days 11-14, there were no other signs of gross toxicity, dermal irritation, adverse clinical effects, or abnormal behavior.
- Body weight:
- All animals gained weight during the study.
- Gross pathology:
- No gross abnormalities were noted for any of the animals when necropsied at the conclusion of the 14-day observation period.
