- Irritant / corrosive response data:
- Corneal opacity was noted in 2/3 animals (grade 11) 1 h after application of the test material.24 h after application of the test material corneal opacity was observed in 3/3 animals (grade 2). These effects were fully reversible within 4 days (1/3 animals) and 7 days (2/3 animals), respectively. Iris effects (grade 1) were recorded in 1/3 animals 24 h after application of the test material, but being fully reversible within 48 h. Conjunctivae effects (grade 1) were observed in 3/3 animals 1 h, 24, 48 and 72 h after application of the test material. These effects were fully reversible within 4 days (2/3 animals) and 7 days (1/3 animals), respectively. Chemosis was observed in 1/3 (grade 1) and 2/3 (grade 2) animals 1 h after application of the test material, but these effects were fully reversible within 72 h (2/3 animals with initially grade 2) and 4 days (1/3 animals with initially grade 1).
- Other effects:
- No mortalities occured during the study period.

Applicant's summary and conclusion
- Interpretation of results:
- Category 1 (irreversible effects on the eye) based on GHS criteria
- Conclusions:
- Under the experimental conditions performed equivalent or similar to OECD TG 405 the test material appeared to be irritating to eyes when applied as 10% (a.i.) formulation.
SCL (worst case assumption due to lack of data for neat substance):
Eye Irrit. Cat. 2 ≥1% (a.i.) and ≤10% (a.i.)
Eye Dam. Cat. 1 >10% (a.i.)
