Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The test item exhibited only minor reddenings of the conjunctivae which were reversible within 48 hours. Thus the registration substance is considered to be not irritating to the rabbit eye and is not subject for labelling requirements.
- Executive summary:
The primary eye irritation potential of the registration substance was evaluated in the New Zealand albino rabbit according to OECD test guideline 405. Only animals without ocular abnormalities were used for the study. o.1 mL of undiluted test material was applied once to the conjunctival sac of the left eye of three rabbits. The untreated eyes served in each case as a control. The exposure period was 24 hours. 24 hours after instillation and at all the designated examination times at which a corneal examination with fluorescein sodium solution took place, the treated eyes were washed out thoroughly with isotonic saline at approx. 37°C. The eyes were examined 1, 24, 48 and 72 hours after application of the test substance. At 24 and 72 hours the eyes were also examined for corneal lesions under UV light after instillation of one drop of 0.01% fluorescein-sodium solution. From one hour up to 24 hours after administration the conjunctivae of 2 animals showed some blood vessels definitely injected. The effects were accompanied by aqueous eye discharge. 48 hours after application all signs of irritation were reversible. Accordingly, the registration substance is not considered to be an eye irritant.
