Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Under the test conditions, the test substance was considered to be non-irritating to the rabbit eye
- Executive summary:
A study was conducted to assess the eye irritation potential of test substance to the rabbit eye according to EU Method B.5. and OECD Guideline 405 in compliance with GLP.
Three animals received 0.1 g of an undiluted test substance into conjunctival sac of the left eye. The other eyes served as untreated control. 24 h after the administration the eyes were washed thoroughly with isotonic saline at 37 °C. The eyes were also washed out at designated examination times at which discharge was observed or a corneal examination with fluorescein was performed.
The eyes were examined 1, 24, 48 and 72 h after administration of the test substance. At 24 and 72 h the eyes were further examined for corneal lesions under UV light after instillation of one drop of a 0.01 % fluorescein-sodium solution. Lesions in cornea, iris or conjunctivae were graded numerically (Scale for scoring ocular reactions). All other changes or toxic effects were recorded when apparent.
One hour after administration the conjunctivae of the animals showed sporadically definitely injected blood vessel and a very slight swelling. In addition, serous by compound discolored eye discharge was noted, 24 h after administration all signs of irritation had completely reversed.
Based on the individual scores after 24, 48 and 72 h, the mean values were calculated to be ‘0’ for opacity of cornea, iris, redness of the conjunctiva and chemosis of conjunctiva.
Under the test conditions, the test substance was considered to be non-irritating to rabbit eye.
