Any other information on results incl. tables
The evaluation of ocular reversibility was not performed because no severe ocular lesion was observed 72 hours after administration of the test substance.
Applicant's summary and conclusion
- Interpretation of results:
- Category 2 (irritating to eyes) based on GHS criteria
- Conclusions:
- The test substance is considered to be irritating to eyes (Category 2) according to GHS criteria.
- Executive summary:
The evaluation of acute ocular irritation and reversibility of NECTARYL in the rabbit was performed according the OECD Guideline No. 405.
The test substance was applied as supplied in the amount of 0.1 ml per animal, into the inferior conjunctival sac of one eye of each of the 6 Zealand hybrid albino male rabbits.
The ocular examinations were performed 1 hour after after administration of the test substance, then at 24, 48 and 72 hours.
Mean values were calculated from the evaluation of the ocular lesions performed in all the rabbits examined at 24, 48 and 72 hours.
The test substance is considered to be irritating to eyes (Category 2) according to GHS criteria
