Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- In an in vivo eye irritation study in rabbits according to OECD guideline 405, the test item was found to be non-irritating to the eyes.
- Executive summary:
In an eye irritation study according to OECD guideline 405 and GLP, the test item was examined undiluted for acute eye irritation/corrosion in three albino rabbits. Eye effects were examined after one hour, and after 24, 48 and 72 hours and scored according to the Draize scala. The test substance caused slight eye effects in all (three) rabbits 1 hour after treatment (slight redness and slight swelling of the conjunctivae) which was graded with a score of 1. After 24 hours, all eye effects had cleared completely (score of 0). The overall 24/48/72 hour score was 0 for corneal opacity, iris, and redness or chemosis of the conjunctivae. On the basis of the results obtained, it was concluded that the undiluted test substance is not an eye irritant and not corrosive to eyes.
