Applicant's summary and conclusion
- Interpretation of results:
- irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- In this study, very well-defined signs of irritation were observed on the treated eyes. Therefire, the test substance shall be classified as an eye irritant.
- Executive summary:
The test substance was investigated for its eye irritating properties according to the method recommended in the OECD Guideline No. 405, "Acute Eye Irritation/Corrosion", Feb. 1987, and EEC Guideline B.5 "Acute Toxicity (Eye Irritation)", Jan. 1997. Three female albino rabbits were exposed to 0.1 ml of the test article in one eye. The eyes were examined and the changes were graded according to a numerical scale one hour, 24, 48 and 72 hours as well as 7, 14 and 21 days after dosing. Very well-defined signs of irritation were observed on the treated eyes. Therefore, the test substance shall be classified as an eye irritant.
