Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The test substance was concluded to be not irritating.
- Executive summary:
In an eye irritation study comparable to OECD TG 405 (no GLP compliance), 100 µl of the test article was applied unchanged into the conjunctival sac of the right eye of six New Zealand White rabbits. Eyes were not rinsed. The left eyes remained untreated and served as controls. Animals were observed 24, 48 and 72 hours and 8 days after the treatment and the irritation parameters were scored. The cornea, iris, conjuctivae and chemosis scores were 0 at all time points (24, 48 and 72 hours) for all animals. Therefore, based on the results of this study, the test article was considered to be not irritating to the eye.
