Applicant's summary and conclusion
- Interpretation of results:
- highly irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Ninate 401-A is extremely irritating.
- Executive summary:
The test substance, Ninate 401A, was tested for eye irritation in accordance with FHSA/CPSC guidelines. The sample was applied at a dose of 0.1 mL undiluted to one eye in each of three albino rabbits. Eyes were graded at 1, 24, 48, 72, 168 and 336 hours. There were positive eye irritation reactions in all of the three test animals. The maximum group mean score was 89.4/110.0 at the 336 hour observation. Ninate 401A is classified as extremely irritating.
