Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Single application of 2000 mg/kg bw of the test substance did not cause lethality in male and female Wistar rats during the 14 day observation period, resulting in a LD50 > 2000 mg/kg bw.
- Executive summary:
One group of five male HoeWISK (SPF71) rats and one group of five female HoeWISK (SPF71) rats were treated with the test item by oral gavage administration at a dosage of 2000 mg/kg body weight. The test item was diluted in vehicle (sesame oil) at a concentration of 20 % (w/v) and administered at a volume dosage of 10 mL/kg.
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, 4 and 6 hours after treatment on day 1 and twice daily (weekends and public holidays once daily) during test days 2-15. Mortality/viability was recorded at approximately 30 minutes, 1, 2, 4 and 6 hours after administration on test day 1 (with the clinical signs) and twice daily (weekends and public holidays once 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 animlas showed sunken flanks, stilted gait and squatting posture. All clinical signs of intoxication were reversible within one day after applikation
Development of body weight was not impaired.
No macroscopic findings were recorded for the animals at scheduled necropsy.
Therefore, the test substance has not to be classified as acutely toxic or as STOT SE according to Regulation (EC) No 1272/2008.
