the eyes of each animal were examined 1, 24, 48 and 72 hours after administration. The irritation was assessed according to the OECD guideline 405. the corrosive properties of the test item and the color of the treated eyes were described and recorded.
TOOL USED TO ASSESS SCORE: hand-slit lamp / biomicroscope / fluorescein
eye examinations were meda with a sllit-lamp 30 SL (C. Zeiss AG) and a Varta Cliotrix diagnostic lamp
Body weights were recorded at pre-test, day 1 and at termination of the study on a Mettler PK 4800 balance.
All animals were killed at the end of the observation period by an intraveneous injection of T61 (Hoechst) into the ear vein.

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The test item has not to be classified as eye irritant according to Regulation (EC) no 1272/2008.
- Executive summary:
The primary eye irritation potential of the test item was investigated according to OECD test guideline No. 405 and Method B.5. The test item was applied by instillation of 0.1 g into the left eye of each of three young adult New Zealand White rabbits. Scoring of irritation effects was performed approximately 1, 24, 48, 72 hours after test item instillation.
The mean score was calculated (separately) for each animal across three scoring times (24, 48 and 72 hours after instillation) for corneal opacity, iritis, redness and chemosis of the conjunctivae. No signs of irritation were recorded for corneal opacity and iritis in all animals. The mean score for chemosis was 0.89. The mean score for conjunctival reddening was 0.67 in two animals, for the remaining animal 1.0.
The instillation of the test item into the eyes caused a severe discharge at the first examination after 1 hour. Blue coloured staining of the conjunctival membrane was noted in all animals at all observations.
With the exception of on female all signs of irritation were reversible and were no longer evident 72 hours days after treatment. Score 1.0 conjuctival reddening observed 72 hours after treatment in one animal is regarded to reverse within a prolonged observation period of 21 days.
No clinical signs of toxicity were observed.
Thus, the test item did not induce significant or irreversible damage to the rabbit eye.
According to the findings in this study, the test item does not meet the criteria for classification according to Regulation (EC) no 1272/2008.
