Applicant's summary and conclusion
- Interpretation of results:
- other: non-irritating
- Conclusions:
- Slight hyperemia was observed in treated rabbit but the effects were not persisted up to 72 hours, hence the test chemical was considered to be not irritating to the eyes of treated New Zealand White rabbit.
- Executive summary:
An ocular irritation study was conducted on New Zealand White rabbit to assess its eye irritation potential.
Approx 100mg of undiluted test chemical was instilled into the eye of rabbit and observed for damage of cornea and mucosa (hyperemia, edema) at 24, 48 and 72 hours.
Slight hyperemia was observed in treated rabbit but the effects were not persisted up to 72 hours, hence the test chemical was considered to be not irritating to the eyes of treated New Zealand White rabbit.
