VEHICLE
no vehicle utilised - Duration of treatment / exposure:
- No washing of the eye after application of test substance performed
- Observation period (in vivo):
- The eyes were examined ophthalmoscopically with a slit lamp prior to the administra-tion and 1, 24, 48, 72 hours and 7, 14 and 21 days after the administration.
- Number of animals or in vitro replicates:
- 3
- Details on study design:
- REMOVAL OF TEST SUBSTANCE

- There were no systemic intolerance reactions.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- According to EC Regualtion 1272/2008 the test item is non-irritating to the eye. Classification and labelling are not necessary.
- Executive summary:
The test substance was tested for its eye irritant potential in rabbit eyes according to OEC 405.
Under the present test conditions, a single instillation of 0.125 mL test item into the conjunctival sac of the right eye of 3 rabbits caused the following changes: Conjunctival redness (grade 1) was observed in all animals 1 hour after administration.
The corneae and the irises were not affected by administration of the test item.
There were no systemic intolerance reactions.
