Additional information

Acute oral toxicity

There are two acute oral toxicity studies in the rat available. One study did not have sufficient documentation available for assessment in the inquiry file (RL4) and was disregarded.

In an acute oral toxicity test (OECD 401/GLP), 1 group of male and female TIf:RAlf (SPF) rats (5/group) were administered the substance in distilled water containing 0.5% carboxymethylcellulose and 0.1 % polysorbate 80 by oral gavage at 2000 mg/kg bw. Clinical signs of toxicity were piloerection, hunched posture, exophthalmus and dyspnoea; all of the animals recovered within 5-6 days. There were no deaths.No macroscopic changes in organs were diagnosed during the gross pathological examination. The LD50 (male/female) was > 2000 mg/ kg bw.

Justification for classification or non-classification

Based on the available information in the dossier, the substance is is not classified for acute oral toxicity, when the criteria outlined in Annex I of 1272/2008/EC are applied.
