Additional information

The L(E)C50 values obtained in the experimental studies for substances with different CAS numbers are comparable by read-across.


Justification for selection of acute toxicity – oral endpoint
The two available experimental studies report similar results, which involve the same hazard classififcation.

Justification for selection of acute toxicity – inhalation endpoint
The selected study is the only study reporting an exact LC50 value.

Justification for selection of acute toxicity – dermal endpoint
The selected study is the only available for the dermal route.

Justification for classification or non-classification

Basing on the L(E)C50 values and according to Regulation 1272/2008/EC, the substance is classified as follows:

Acute Tox. 4, H302

Acute Tox. 4, H332
