Applicant's summary and conclusion

Interpretation of results:

not classified

Remarks:

Migrated information Criteria used for interpretation of results: EU

Conclusions:

The oral LD50 of the substance is higher than 2000 mg/kg bw in mice. Therefore it is not classified according to Directive 67/548/EEC and CLP Regulation (EC) N° 1272/2008.

Executive summary:

In an acute oral toxicity study performed similarly to OECD Guideline 401, groups of mice (1 or 3/sex/dose) were given a single oral dose of the substance at 2, 5 and 10 mL/kg bw. Animals were then observed for mortality, clinical signs and bodyweights for 7 days and were all macroscopically necropsied after sacrifice.

No mortality and no abnormal clinical signs were observed. Animals dosed at 10 mL/kg bw were showing signs of stress within 30 minutes after treatment but recovered within one hour. The overall body weight gain of the treated animals was not affected by treatment with the test item except one female dosed at 5 mL/kg bw that lost a gram. No macroscopic abnormalities were observed at study termination except pale intestines in the mice dosed at 10 mL/kg bw. In this study, the combined oral LD50 was considered to be higher than 10 mL/kg bw (equivalent to 8900 mg/kg bw) in mice.

Under the test conditions, the oral LD50 is higher than 2000 mg/kg bw in mice. Therefore the substance is not classified according to Directive 67/548/EEC and CLP Regulation (EC) N° 1272 /2008.
