- Conclusions:
- An acute oral LD50 >2000 mg/kg bw was determined for the test substance.
- Executive summary:
The acute oral toxicity test was conducted according to OECD guideline 423, EU method B.1, EPA OPPTS 870.1100, JMAFF guidelines, and GLP principles. Female wistar rats were dosed 2000 mg/kg bw of test substance by gavage. No mortality or abnormal findings were reported.

Additional information
The acute oral toxicity test was conducted according to OECD guideline 423, EU method B.1, EPA OPPTS 870.1100, JMAFF guidelines, and GLP principles. Female wistar rats were dosed 2000 mg/kg bw of test substance by gavage. No mortality or abnormal findings were reported. An LD50 >2000 mg/kg bw was determined for the test substance (Wil, 2012).
The acute dermal toxicity test was conducted according to OECD guideline 402, EU method B.3, EPA OPPTS 870.1200, JMAFF guidelines, and GLP principles.

The acute dermal toxicity LD50 of >2000 mg/kg bw was determined for the test substance (Wil, 2012).
Justification for classification or non-classification
An LD50 (oral) >2000 mg/kg bw and LD50 (dermal) >2000 mg/kg bw were determined for the test substance. Based on these results, the test substance does not warrant classification as per the EU CLP Regulation (EC) No 1272/2008.
