Description of key information

MBTester is not toxic via the oral and dermal route. The LD50 values are greater than 10000 and 2000 mg/kg bw, respectively.
Inhalation is not a relevant route of exposure because of the low vapour pressure and the lack of inhalation exposure via aerosols.

Additional information

MBTester is not toxic via the oral and dermal route.the LD50 values are greater than 10000 and 2000 mg/kg bw, respectively.

Inhalation is not a relevant route of exposure because of the low vapour pressure (0.0002 Pa at 20 °C) and the lack of inhalation exposure via aerosols.


Justification for selection of acute toxicity – oral endpoint
MBTester is not toxic via the oral route. The LD50 values are greater than 10000 mg/kg bw.

Justification for selection of acute toxicity – inhalation endpoint
Inhalation is not a relevant route of exposure because of the low vapour pressure and the lack of inhalation exposure via aerosols.

Justification for selection of acute toxicity – dermal endpoint
MBTester is not toxic via the dermal route. The LD50 values are greater than 2000 mg/kg bw.

Justification for classification or non-classification

On the basis of the test results no classification is necessary.
