Results and discussion
Effect levels
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- 1 080 mg/kg bw
- Based on:
- act. ingr.
- Mortality:
- Virtually all animals died in doses of 1220 mg/kg and above.
- Clinical signs:
- other: Symptoms beginning about 30 minutes past application included diarrhea, squatting attitude, breathing difficulties, nose bleeding, ataxia, and lethargy. These symptoms had disappeared in surviving animals by 120 hours.
- Gross pathology:
- In the animals that died before the end of the study, red mucous was seen in the stomach and intestine. In the surviving animals, hyperemia of the stomach was noted, along with abnormalities of the stomach, liver, spleen, kidneys, and the peritoneum.

Applicant's summary and conclusion
- Interpretation of results:
- Toxicity Category IV
- Conclusions:
- The acute oral LD50 is 1080 mg/kg. According to EU GHS guidelines, the test substance is a Category IV toxicant.
- Executive summary:
This study examined the oral toxicity of the test substance in rats. Groups of 5 male and 5 female rats were exposed orally to 0, 1075, 1220, 1360, or 1710 mg/kg of test substance. The animals were then monitored for 14 days for mortality and clinical signs. All animals showed signs of toxicity. Mortality was seen at all dose levels, with 4 of 10 animals at the lowest dose level dying. All animals at the highest dose level died. The acute oral LD50, when adjusted for activity was 1080 mg/kg. According to EU GHS guidelines, the test substance is a Category IV toxicant.
