Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The median lethal dose of MG-60 after single dermal administration to rats of both sexes, observed over a period of 14 days is: LD50 (rat): greater than 2000 mg/kg body weight
- Executive summary:
Five male and five female HanBrl: WIST (SPF) rats were treated with MG-60 at 2000 mg/kg by dermal application. the test item was diluted in vehicle (purified water) at a concentration of 0.5 g/ml and administered at a volume dosage of 4 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 clinicla signs at approximately 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 1,2, 3 and 5 hours after treatment on day 1 and twice daily during test 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 stud.
No clinical signs 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.
