Applicant's summary and conclusion
- Interpretation of results:

- Executive summary:
In a GLP compliant OECD guideline study, three female HanRcc :WIST (SPF) rats, were treated with the test substance by oral gavage administration at a dosage of 5000 mg/kg body weight. The test item was diluted in an aqueous solution of 0.5 % w/v carboxymethyl cellulose at a concentration of 0.25 g/mL and administered at a volume dosage of 20 ml/kg, respectively. The animals were examined daily during the acclimatization period and mortality, viability and clinical signs were recorded. All animals were examined for clinical signs at approximately 30 minutes, 1, 2, 3 and 5 hours after treatment on day 1 and once daily during test days 2-15. Mortality/viability was recorded at approximately 30 minutes, 1, 2, 3 and 5 hours after administration on test day 1(with the clinical signs) and twice daily during days 2-15. Body weights were recorded on day 1(prior to administration) and on days 8 and 15. All animals were necropsied and examined macroscopically. All animals survived until the end of the study period. The first treated animal was noted with slightly ruffled fur from the 2-hour reading to test day 5. Black feces were seen in the cage from the 5-hour reading to test day 4. All clinical signs were reversible and no longer evident from test day 6 to the end of the observation period. The second treated animal was noted with slightly ruffled fur from the 30-minute to the 3-hour reading. This clinical sign was reversible and no longer evident from the 5-hour reading to the end of the observation period. The third treated animal was noted with slightly ruffled fur from the 30-minute to the 5-hour reading. This clinical sign was reversible and no longer evident from test day 2 to the end of the observation period. The body weight of the animals was within the range commonly recorded for this strain and age. No macroscopic findings were recorded at necropsy. Therefore, the LD50 (female rat) was determined to exceed 5000 mg/kg body weight.
