- Photoperiod (hrs dark / hrs light): 12/12

Test system

Vehicle:
unchanged (no vehicle)
Controls:
other: untreated eye of the same animal
Amount / concentration applied:
0.1 mL to the conjunctival sac of the right eyelid
Duration of treatment / exposure:
24 h
Observation period (in vivo):
72 h
Number of animals or in vitro replicates:
3
Details on study design:
- Both eyes were examined before application of the test substance for signs of pre-existing irritation, reaction or abnormality which would prevent it from being used in the study.
- Weight determination: shortly before application of the test substance
- The test substance was not washed out.
- Readings: 1, 24, 48 and 72 h after application
- A check for general observation and mortality was made twice each working day and once on weekends and on public holidays.
- SCORING SYSTEM: Cornea, conjunctivae, chemosis and iris effects as stated in the OECD 405 guideline

Applicant's summary and conclusion

Interpretation of results:
not irritating
Remarks:
Migrated information
Conclusions:
Under the conditions of the test the substance is considered to be not corrosive or irritating to the eye.
Executive summary:

The potential to cause damage to the conjunctiva, iris or cornea was assessed in an OECD 405 guideline study (in compliance with GLP) in 3 white Vienna rabbits subjected to a single ocular application of 0.1 mL of the test substance on day 0. The average score (24 to 72 hours) for irritation was calculated to be 0 for corneal opacity, iris, chemosis, and 0.9 for conjunctivae redness (in which two animals had a score of 1 and one a score of 0.7). The findings were reversible withing 72 hours after application. It was concluded that the test substance was not irritating to the eye.
