Applicant's summary and conclusion

Interpretation of results:
not irritating
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
The test item applied to the rabbits’ eye mucosa, caused conjunctival irritant effects (grade 1-2) at one hour which were reduced at 48 hours after application. The effects were fully reversible within 72 hours. There were no corneal effects observed in the study. The test material is a non-toxic after acute eye application and is therefore considered to be not irritating to the eye according to the Draize classification system.
