Additional information

Justification for classification or non-classification

The test material was evaluated for in vivo oral and dermal acute toxicity. The test material was observed to be orally non-toxic in doses up to 5000 mg/kg bw and dermally non-toxic in doses up to 2000 mg/kg bw. GHS criteria (Regulation EC No. 1272/2208) for classification as acutely toxic are not met.
