Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Executive summary:
The test article was intilled into the left eye of six albino rabbits. The eyes examined 1, 24, 48, 72 hours after treatment. Te test article produced irritation ranging from mild to moderate in the treated eye up to Day 2. However, complete reversibility was evident by Day 3. Under the conditions of the present study, the test article appears to possess minimal irritation potential.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
