- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Remarks on result:
- other: No mortality was observed.
- Mortality:
- No deaths occurred in the treated animals of either sex. The LD50 was not calculated and it was considered higher than 2000 mg/kg.
- Clinical signs:
- other: No clinical changes were seen in the animals.
- Gross pathology:
- At the autopsy carried out at the end of the observation period, no appreciable macroscopic findings were evident in any treated rat.
Applicant's summary and conclusion
- Interpretation of results:
- other: Not Classified
- Conclusions:
- No deaths or clinical signs occurred in the treated animals. Body weight growth of the treated animals was normal during the observation period. At the final killing no appreciable macroscopic findings were evident in any animal.In conclusion, the LD50 of the test article, when administered to rats as a single dose by oral route, was higher than 2000 mg/kg. At this dose the compound did not induce mortality or apparent signs of toxicity in the treated rats.
- Executive summary:
An acute oral toxicity study of test chemical was conducted in Sprague Dawley Crl:CD(SD) BR rats 5 males and 5 females) in accordance with the OECD Guideline 401 (Acute Oral Toxicity) and EEC Guidelines (B.1).
The test article was administered undiluted as supplied at the dosage of 2000 mg/kg. The volume of administration was 1.44 ml/kg (the density of the test article is 1.39 g/ml).
All rats were treated after a 16-hour fasting period. The day of treatment was considered day 1 of the study. The animals were weighed twice before treatment (at randomization and on day 1 just before treatment) and on days 3, 8 and 14. They were clinically observed for 14 days following the treatment. On day 15 the rats were killed (fasted overnight) by excision of the femoral arteries after i.p. overdosage anesthesia with 5% sodium pentobarbital and were subjected to a thorough autopsy.
No deaths or clinical signs occurred in the treated animals. Body weight growth of the treated animals was normal during the observation period. At the final killing no appreciable macroscopic findings were evident in any animal.
In conclusion, the LD50 of the test article, when administered to rats as a single dose by oral route, was higher than 2000 mg/kg. At this dose the compound did not induce mortality or apparent signs of toxicity in the treated rats.
