Treated animals were then observed for mortality, clinical signs and body weight changes for 14 d and were then culled and subjected to gross pathological examination. In the first step, the test substance was administered to a group of 3 females at 2,000 mg/kg bw. A second group of 3 females was then dosed at the same level. No mortality and no signs of toxicity were observed. No abnormalities were recorded at necropsy. Based on the findings of the study, the oral LD50 of the test substance was determined to be >2,000 mg/kg bw (Caruso R, 2015).

Acute dermal toxicity
A study was conducted to assess the acute dermal toxicity of the test substance in Hsd:Sprague-Dawley rats according to OECD Guideline 402, EU Method B.3 and EPA OPPTS 870.1200, in compliance with GLP.

Justification for classification or non-classification
Based on the results of acute oral and dermal toxicity studies, the test substance does not warrant classification for acute toxicity according to the EU CLP (EC 1272/2008) criteria.
