Additional information
Conclusion on classification
The LC/EC50s for acute aquatic endpoints (96-hour LC50 in fish of 1.78 mg/L; 48-hour EC50 of 92.9 mg/L in daphnids, and 72-hour ErC50 of >14.4 mg/L in algae) do not warrant an acute aquatic classification according to EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008. The NOEC of 0.131 mg/L in a fish early life cycle study along with the lack of ready biodegradation would warrant a Chronic Aquatic Cat 2 ( H411: Toxic to aquatic life with long lasting effects) according to EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008.
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.
