Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The test report describes a valid guideline study without information about GLP compliance. The test substance was not irritating to the rabbit eye under the conditions of the study.
- Executive summary:
An eye irritation study was conducted using a similar procedure to that described in the current OECD Guideline 405 (Reckers, 1981). The test material (CAS No. 73984 -93 -7) was applied at a volume of 0.1 mL to the right eye of six female rabbits (strain: New Zealand White). The test article was left in the right eye (i.e. no rinsing was performed) and the rabbits were observed during application followed by a 14 -day observation period. The left eye served as control. The treated eye was scored at day 1, 2, 3, 4, 7 and 14 following instillation. Ocular irritation was not observed in any animal during the study.
