Test system
- Vehicle:
- unchanged (no vehicle)
- Controls:
- other: The left eye remained untreated and was used for control purposes.
- Amount / concentration applied:
- TEST MATERIAL
- Amount(s) applied: 0.1 mL - Duration of treatment / exposure:
- 24 hours
- Observation period (in vivo):
- 24 hours
- Number of animals or in vitro replicates:

- Details on study design:
- SCORING SYSTEM:
Primary eye irritation was evaluated at 1 and 24 hours after dose administration. The cornea, iris and conjunctiva were scored separately according to the Draize system.
TOOL USED TO ASSESS SCORE:
Examination for irritation was accomplished with a pen light. The eyes were then treated with sodium fluorescein and examined with a slit light equiped with a cobalt blue filter.

- Irritant / corrosive response data:
- Test article instillation caused severe ocular irritation characterised by corneal opacity, iritis and conjunctival irritation with blistering. Twenty four hours after dose administration the treated eye was extremely swollen and the cornea could not be examined.
Due to the severe ocular irritation that was noted, the study was terminated after the 24 hour reading.
Applicant's summary and conclusion
- Interpretation of results:
- Category 1 (irreversible effects on the eye) based on GHS criteria
- Conclusions:
- Due to the severe ocular irritation that was noted, this study was terminated after the 24 hour reading and as a result can be considered as corrosive.
- Executive summary:
The test material was evaluated for potential primary eye irritation using one New Zealand White rabbit. The rabbit was administered 0.1 mL of the test article to the conjunctival sac. The untreated contralateral eye served as a control. Both eyes were examined and ocular irritation was scored according to the Draize method at 1 and 24 hours after dose administration.
Test article instillation caused severe ocular irritation characterised by corneal opacity, iritis and conjunctival irritation with blistering. Twenty-four hours after dose administration, the treated eye was extremely swollen and the cornea could not be examined. The untreated eye appeared normal during the observation period.
Due to the severe ocular irritation that was noted, this study was terminated after the 24 hour reading.
