Description of key information
For the skin irritation test, the dorsal part of three New Zealand white rabbits after single dermal application with the test article for 4 hours were observed by experienced veterinarian, and found that there was no irritation response within 72 hours after patch removal. The primary irritation index (PII) of the test article was zero.
For the eye irritation test, the local irritation response of the rabbit eye were evaluated within 72 hours after the application. The result of this study indicated that all the three rabbit did not show any eye irritation response after application of the test article.
