Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- In a reliable study predating GLP conducted according to a standard guideline very similar to OECD Test Guideline 405 with acceptable restrictions, the test material was concluded to be not irritating to the eyes of rabbits.
