Applicant's summary and conclusion
- Interpretation of results:
- irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Based on the results of this study, Flotanol F is considered to be irritating to eyes.
- Executive summary:
The primary eye irritation potential of Flotanol F 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 as well as 7 and 14 days 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 72 hours after administration the conjunctivae of the animals showed definitely injected blood vessels up to a diffuse crimson color. The effects were accompanied by aqueous eye discharge. Additionally, from one hour up to 72 hours slight scattered or diffuse areas of corneal opacity as well as sporadic iridial effects were noted in some animals. 7 days after application all signs of irritation were reversible. Accordingly, the tested Flotanol F is considered to be an eye irritant.
