Applicant's summary and conclusion

Interpretation of results:
irritating
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
The test substance induced eye irritation
Executive summary:

Six rabbits were treated with the test substance in an eye irritation test. During the observation period of 72 hours severe eye irritation was reported, which was not shown to be reversible. In view of the absence of effects on the iris and a mean overall score of 1.3 for cornea, it was concluded that the test substance is a category 2 eye irritant.
