- Irritant / corrosive response data:
- Approximately 1 h post-application two animals showed diffuse conjunctival redness and slight chemosis; the other animal showed slight conjunctival redness and slight chemosis. The conjuctival redness was fully reversible in one animal by day 3 and in the other two animals between days 3 and 7. The chemosis resolved within 24, 48 or 72 hours for each rabbit separately. Treatment of the eyes with fluorescein 24 hours after exposure revealed no epithelial damage in any of the animals.
Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- CLP: not classified
DSD: not classified - Executive summary:
Instillation of approximately 60 mg of the test substance in one of the eyes of each of three albino rabbits resulted in slight to diffuse redness of the conjuctivae and slight chemosis. The conjuctival redness had resolved in one animal by day 3 and in the other two animals between days 3 and 7. The chemosis resolved within 24, 48 or 72 hours for each rabbit separately. Based on the estimated Draize score of 6 (60 minutes) the test substance should be classified as mildly irritating according to the scheme of Kay and Calandra. According to the criteria laid down in Annex VI of the EEC Council Directive 67/548/EC (amended by Directive 83/467/EEC), the test substance need not be labelled as an eye irritant.
