Study design
The objective of the present study was to investigate the eye irritating potential of the test item in rabbits. For this purpose, the test item was applied in a single dose to the left eye of rabbits, the untreated right eye served as control. The degree of eye irritation was evaluated by scoring lesions of conjunctiva, cornea and iris at specific intervals. The first examinations of the eyes followed 1 and 6 hours after treatment. Subsequently, the eyes were investigated twice daily for a further 4 days. In addition, potential systemic effects and the body weight development was determined.
The study was performed initially with one animal, followed by the confirmatory test with two further animals.
Results
No mortality occurred and no clinical symptoms were seen during the experimental phase of the study. The body weight development of the rabbits was inconspicuous.No signs of irritation were observed at the cornea or iris after instillation of the test item. Two animals showed redness of the conjunctivae (score 1) 1 hour after treatment, that recovered completely 6 hours after administration. No abnormalities were detected in the untreated eyes.
Conclusion
Under the conditions of the present study, no eye irritating potential was detected for the test item.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Under the conditions of the present study, no eye irritating potential was detected for the test item.
- Executive summary:
The study was performed according to OECD 405 under GLP conditions. Under the conditions of the present study, no eye irritating potential was detected for the test item.
