Applicant's summary and conclusion
- Interpretation of results:
- Category 2A (irritating to eyes)
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Under the test conditions, Chimexane NB is classified as “R36 irritating to eyes”, according to the Annex VI of the Directive 67/548/EEC and "irritating to eyes (Category 2)" according to the Regulation (EC) N° 1272-2008 (CLP).
- Executive summary:
In an eye irritation study conducted according to the OECD Guideline 405, 3 healthy male rabbits of the New Zealand White strain were exposed to 0.1 mL of undiluted test item Chimexane NB in their right eye while the left eye remained untreated and served as control. The eyelids were then gently held together for about one second to avoid any loss of test item. At 24 h after treatment, fluorescein solution was instilled into the eyes and they were examined under UV-lamp to detect possible corneal damage. The eyes were examined and the changes were observed at 1, 24, 48 and 72 h and up to Day 9 after treatment and graded according to the method of OECD Guideline 405.
One hour after instillation of the substance, redness of the palpebral and bulbar conjunctivae with abundant discharge and slight chemosis were observed. Slight iris congestion observed in three rabbits disappeared in less than 48 h. 24 h later, conjunctival reactions (redness and chemosis) increased slightly and a partial corneal opacity was noticed in two rabbits, it disappeared in less than 4 days. Complete reversibility occurred within about a week in all animals. Mean individual scores at 24, 48 and 72 h after exposure for the 3 animals were 1.3, 0.0, 0.7 for cornea score; 0.3, 0.0, 0.3 for iris score; 3.0, 2.0, 2.3 for conjunctivae score and 1.7, 1.0, 1.0 for chemosis score. In this study, Chimexane NB is an eye irritant on male rabbits.
Under the test conditions, Chimexane NB is classified as “R36 irritating to eyes”, according to the Annex VI of the Directive 67/548/EEC and ‘irritating to eyes (Category 2)’ according to the Regulation (EC) N° 1272-2008 (CLP).
