Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Executive summary:
In an acute oral toxicity study performed according to the Acute Toxic Class Method, a dose of 2000 mg/kg bw of the test material (solvent free) (preparations in deionized water) were administered by gavage to two test groups of three fasted Wistar rats each (6 females).
The following test substance-related clinical observations were recorded, clinical signs occurred within the first 6 days after administration:
2000 mg/kg (first test group):
- Mortality in one animal
- Impaired general state in all animals
- Cowering position in two animals
- Piloerection in all animals
- Reduced defecation in one animal
- Macroscopic pathological findings in the animal that died:
- Advanced putrefaction
- Red discoloration of the stomach and intestine
- Dark discoloration of the liver and spleen
2000 mg/kg (second test group):
- No mortality occurred
- Impaired general state in all animals
- Cowering position in all animals
- Piloerection in all animals
The body weights of the surviving animals (5 females) increased within the normal range throughout the study period.
There were no macroscopic pathological findings in any animal sacrificed at the end of observation period (5 females).
The acute oral LD50 was calculated to be LD50, oral, rat > 2000 mg/kg bw.
