Applicant's summary and conclusion

Interpretation of results:

GHS criteria not met

Conclusions:

Based on the results of the study, the test article is not an ocular irritant.

Executive summary:

The primary eye irritation/corrosion potential of the test article was evaluated in New Zealand White Rabbits. This study was performed in accordance with OECD GLP (1999). The study design was based on OECD 405 (1987) and Directive 92/69/EEC guideline B.5 (1992). Approximately 24 hours prior to the study the eyes of all animals were examined using a fluorescein solution. Animals without ocular abnormalities were selected for this study. The test material (0.1 mL) was administered as received to the conjunctival sac of the left eye of three rabbits. The contralateral eye served as the control. The treated eyes were washed with 37 C saline at 24 hours post-dose. The eyes were examined for irritation of the cornea, iris and conjunctiva at 1, 24, 48 and 72 hours post-dose using the Draize technique. Sodium fluorescein dye procedures were used at 24 and 72 hours after dosing to improve the evaluation of the cornea. One hour after dosing, the conjunctivae of one animal showed definitely injected blood vessels (score: 1). At 24 hours after dosing, all animals were normal. Based on the results of this study, the test article is not an ocular irritant.
