Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
According to OECD 402 test method, the LD50 of Everlan SL65 was greater than 2000 mg/kg B.W.. Therefore, Everlan SL65 was Category 5 based on GHS criteria.
Executive summary:

This test using the procedures outlined in the SuperLab for M62-151100100001EN which is based on the SOP (SOPP-342) for the OECD 402 and OECD 402 (OECD, 1987). Six male and six femaleSprague-Dawley rats for each group were used in limit test. For Test group, 12 Sprague-Dawley ratsweredermally dosed with 2000 mg/kg B.W. of Everlan SL65. 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 Everlan SL65 was greater than 2,000 mg/kg B.W..
