TOOL USED TO ASSESS SCORE: both eyes of the rabbits were examined for occular abnormalities prior to initiation of dosing, including the use of sodium fluorescein and UV light for detection of corneal abnormalities. Both eyes were examined macroscopically for ocular irritation using a hand-held penlight in accordance with the method of Draize.
OBSERVATIONS: animals observed twice daily for mortality. Body weight recorded on day 0 and at termination. The eyes were examined for ocular reactions in accordance with the method of Draize at approximately 1, 24, 48, and 72 hours after dosing and on day 4 if irritation persisted.

- Irritant / corrosive response data:
- - None of the rabbits vocalised upon installation of the test material.
- The left (control) eyes were free of evidence of ocular irritation and other findings for the duration of the study.
- There were no test material related deaths, clinical findings, or body weight changes during the study period. The maximum average score for the substance was 8.0 at one hour post instillation. Positive conjunctival irritation was noted for 4/6 rabbits. All animals had minor conjunctival irritation. There were no iridal or corneal findings. All irritation was reversible and completely subsided by day 4. - Other effects:
- One female (no. 21091) lost 390g (14 %) of initial (day 0) bodyweight. This weight loss was not considered to be related to test material administration. There were no other remarkable changes or differences observed in body weights during the study period.

Applicant's summary and conclusion
- Interpretation of results:
- other: not classified as an eye irritant according to the CLP Regulation (EC) No.1272/2008.
- Conclusions:
- The substance is not considered to be an eye irritant.
- Executive summary:
The ocular irritation potential of the substance was evaluated according to the OECD Guideline 405 and EPA OTS 798.4500. For this reason, three male and three female New Zealand White Rabbits were used. Single doses of the test material were instilled into the lower conjuctival sac of the right eye of 6 albino rabbits. The eyelids were held closed for approximately 1 second and released. Left eyes were manipulated in a similar manner as the right eyes and served as contralateral controls. The eyes of all animals remained unwashed.
The eyes were examined for ocular reactions in accordance with the method of Draize at approximately 1, 24, 48, and 72 hours after dosing and on day 4 if irritation persisted. Sodium fluorescein was used to aid in revealing possible corneal damage at 24, 48, and 72 hours and on day 4. Positive conjunctival reactions were noted in the treated eye of 4 animals while minor conjuctival irritation was noted for all rabbits. There were no corneal or iridal findings. All irritation was reversible and completely subsided by day 4 or earlier.
Based on the irritation scores the substance is not considered to be an eye irritant.
