Any other information on results incl. tables
The cornea score of eyes which were treated with fluorescein after the first 24 h reading was zero for all animals.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The test material was considered to be not irritating to rabbits' eyes.
- Executive summary:
The eye irritating potential ot the test material was investigated in a GLP-conform study according to OECD guideline 405. Four female albino rabbits were exposed to 0.1 mL of the test material in the left eye. Eye reactions were observed after 1 h, 24, 48 and 72 hours after expsoure. Slight signs of effects were observed on the treated eyes, but all effects were fully reversible within 72 hours. The mean scores for cornea opacity and iris score calculated for the time points 24, 48 and 72 hours were 0 for all animals. The conjunctiva score were calculated to be 0.33 for all animals. The chemosis score was calculated to be 0 for animal 1 and 0.33 for the three remaining animals. Based on these results, the material was not irritating to rabbits' eyes.
