- Irritant / corrosive response data:
- Chemosis: At the 1h time point, 2/3 animals were scored grade 1 and 1/3 animals was scored grade 2 for chemosis. This effect was fully reversible within 24 h (1 animal scored grade 1 at 1 h) or 48 h (1 animal scored grade 2 and 1 animal scored grade 1 at 1 h), respectively. Conjunctivae redness: 1 h after administration, all three animals were scored grade 1 for conjunctivae redness. This effect was fully reversible within 24 h (1/3 animals) or 48 h (2/3 animals), respectively. No effects on iris and cornea opacity were noted in any animal.
Applicant's summary and conclusion
- Interpretation of results:
- other: CLP/EU GHS criteria not met, no classification required according to Regulation (EC) No 1272/2008
- Conclusions:
- The study is in accordance with OECD TG 405, was conducted under GLP and is considered valid and reliable. Under the conditions chosen the test substance did induce irritation to the eye (conjunctivae and chemosis score) of 2/3 rabbits at the 24h reading time point, but the observed effects were fully reversible within 48 h. According to criteria of the CLP Regulation (EU) No. 1272/2008, no classification of the test item for eye irritation is required.
