Applicant's summary and conclusion
- Interpretation of results:
- other: not classified under Regulation 1272/2008
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The substance was tested for eye irritation following OECD 405. Under the experimental conditions it did not show any irritation potential to the eye.
- Executive summary:
The substance was tested following OECD 405 for eye irritation. Three New Zeland rabbits were injected with the sample in water and checked regularly. None of the animals showed a score (chemosis, redness and discharge of the conjunctiva, iris and corneal opacity) higher than 1 and the effects were fully reversible within the period of observation.
