Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- This key study for eye irritation is performed according to GLP and similar to OECD guideline 405, in which the Draize scoring system is used. New Zealand White rabbits were exposed to a single dose of 76 mg of test substance via the eye. Signs of irritation were recorded on the first, second and third day after dosing. Only on the first day signs of irritation were noted in 3 of the 6 test animals. By day 2, all animals were free of irritation signs.
