Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Based on the test result, it is concluded that the test substance is not irritating to eyes.
- Executive summary:
A study was performed to assess the irritancy potential of the test material to the eye of the New Zealand White rabbit. The method used followed that described in the OECD Guidelines for Testing of Chemicals (1987) No. 405 "Acute Eye Irritation/Corrosion" referenced as Method B5 in Commission Directive 84/449/EEC.
A single application of the test material to the non-irrigated eye of three rabbits produced slight iridial inflammation and minimal conjunctival irritation. All treated eyes appeared normal 24 hours after treatment.
Based on these findings it is concluded that the test item is not irritating to eyes.
