Results and discussion

Any other information on results incl. tables

Results of the rinsed right eye:

Conjunctiva: mild swelling and mild discharge only at the day of treatment; no other conjunctival effect

Cornea: no effect

Iris: no effect

Results of the unrinsed right eye:

Applicant's summary and conclusion

Interpretation of results:
other: irritating effects
Remarks:
Criteria used for interpretation of results: expert judgment
Conclusions:
The mean for the rating of irritating effects to cornea (slight opacity) at 24h, 48h, 72 h is 1. Since only one animal is tested the substance is classified preventatively as irritating to eyes, cat. 2 according to (EC) No 1272/2008.
There is no classifictation according to Directive 67/548/EEC.
