Applicant's summary and conclusion

Interpretation of results:
Category 5 based on GHS criteria
Conclusions:
According to OECD 423 test method, the LD50 of CR SB07 was greater than 2000 mg/kg B.W.. Therefore, CR SB07 was Category 5 based on GHS criteria.
Executive summary:

This test using the procedures outlined in the SuperLab for M62-151100050001EN which is based on the SOP (SOPP-341) for the OECD 423 and OECD 423 (OECD, 2001). A total of 6 female Sprague-Dawley rats were orally dosed with CR SB07 in three animals each group, at 2000 mg/kg b.w. for both Group 1 and Group 2 in limit test. All animals tolerated the test article well with increasing body weights and no mortality or gross lesions findings reported. In absence of mortality or other significant clinical signs of toxicity, LD50 of CR SB07 was greater than 2,000 mg/kg.
