Applicant's summary and conclusion

Interpretation of results:
not irritating
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
Based on the result of this study the substance was not considered to cause serious eye irritation or damage.
Executive summary:

The substance was tested for eye irritation according to OECD guideline 405. 3 New Zealand albino rabbits were treated with 100 mg of the test substance placed into in the left conjunctival sac of the left eye. The untreated right eyes served as control. The observation period lasted 72h. From one to 24 hours after application moderate conjunctival redness and chemosis were observed. All symptoms were fully reversible within 2 days.
