Applicant's summary and conclusion

Interpretation of results:
other: The study cannot be used for assessment due to its insufficient documentation.
Conclusions:
The tested substance caused weak signs of irritation to the eyes, but based on the available data no conclusion on classification can be made.
Executive summary:

A study was performed to assess the irritation of the test material to the eyes. Six rabbits were used. As a result, conjunctiva and cornea findings were made which were not reversible within 72 hours. Based on the applied scoring system, the substance was found to cause weak signs of irritation to the eyes. Due to the limited documentation no conclusion can be made on classification.
