Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The present study, to investigate the acute eye irritation and corrosion of S E Z-250, w as conducted with rabbits. After applica tion of test substance 0.1 m L in the eye of rabbit, param eters such m ortality, clinical signs, body w eight changes and local irritation were m easured during 72 hours observation period after application of test substa nce .
No clinical signs and m ortality were observed relating to test substance treatm ent. All tested anim als show ed norm al gains in body w eight.
After application o f test substance, eye irritation such as chem osis(sw ellin g) was observe d in all tested animals.
A ccording to the criteria for the evalua tion o f eye reactions specifie d by the Globally Harmonized System o f Classification and Labelling of Chemicals(GHS), the present observation provides only slight eye irritation. Therefore , SEZ-250 was not classified by "Hazard Class" on this study.
