Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
A study in rabbits was conducted to evaluate the irritation potential of the test substance in the eye. The results showed a minimal irritation effect of the test substance on rabbit eyes.
Executive summary:

The potential of the test substance to cause eye irritation was tested using rabbits accordin to OECD 405. The animals were observed for 72 hours. The mean score for cornea opacity and iris were 0 for 24/48/72 h. For conjuntivae redness it was 0.33 and for chemosis 0 at 24/48/72 h. For all animals the individual mean scores for cornea opacity and iris were 0 for 24/48/72 h. Animal 1 had a score for conjuntivae redness of 0.33 and 0 for chemosis at 24/48/72 h. Animal 2 had a score for conjuntivae redness of 0.33 and 0 for chemosis at 24/48/72 h. Animal 3 had a score for conjuntivae redness of 0.33 and 0 for chemosis at 24/48/72 h. All effects observed were reversible within 48 h. Due to these results the test substance was found to be slightly irritating for the eye but without classification.
