Additional information
Conclusion on classification
Based on all available ecotoxicological data for daphnids, fish and algae and the physico-chemical properties of the substance, the substance should not be classified and labelled according to the EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008. Although the substance shows no acute toxicity up to the limits of water solubility and is not readily biodegradable, the water solublity is greater than 1 mg/L (and hence should not be considered a “poorly water soluble” substance) and the log Kow of >9.4 indicates that the substance is not likely to bioaccumulate.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
