Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The median lethal dose of Fexo-07 after single dermal administration to rats of both sexes, observed over a period of 14 days is:
LD50 (rat): > 2000 mg/kg body weight. - Executive summary:
Five male and five female HanRcc:WIST (SPF) rats were treated with Fexo-07 at 2000 mg/kg by dermal application. The test item was diluted in vehicle (PEG 300) at a concentration of 0.33 g/mL and administered at a volume dosage of 6 mL/kg.
The application period was 24 hours.
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. Local signs were noted once daily from test day 2 to 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. No deaths occurred during the study. No clinical signs of toxicity or local dermal findings were observed during the course of the study. The body weight of the animals was within the range commonly recorded for this strain and age. No macroscopic findings were observed at necropsy.
