Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
The present study, to investigate the acute dermal irritation and corrosion of SEZ-250, was conducted with rabbits. The test substance was applied to the skins of rabbits for 4 hours. Parameters such as mortality, clinical signs, body weight changes and local irritation were measured for 72 hours observation period after application of test substance.

No clinical signs and mortality were observed relating to test substance treatment. All tested animals showed normal gains in body weight.

After application of test substance, dermal corrosion and irritation were not observed in all animals. The skin irritation score was calculated "0.00" in all animals.

According to the criteria for the evaluation of dermal reactions specified by the Globally Harmonized System of Classification and Labelling of Chemicals(GHS), the present observation provides no evidence of either corrosion or irritation. Therefore, SEZ-250 was not classified by "Hazard Class" on this study.
