EC100 (24h) > 5.5 mg/L
It is not possible to determine EC50 because the immobility of most daphnias was affected by deposits of test substances in their body. This is a consequence of a low solubility of the substance in water. Other physico-chemical properties support this result: the surface tension of the substance is considered high and won't be wetted and will be absorbed by the invertebrates.
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.
