Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: other: FHSA
- Conclusions:
- A study in 6 rabbits suggested that Santovar was slightly to not irritanting for the eye; reversibel (within 48 hours) erythema was described. The study was not performed according to the general guidelines for acute eye irritation/corrosion under GLP conditions and was very poorly documented. Therefore, the information may be considered reliable with major restrictions.
