Additional information
Conclusion on classification
Acute toxicity data are available for fish, daphnia, and algae, indicating that algae is the most sensitive species. The 72-hour ErC50 is 46.8 mg/L. Therefore, the test substance is not classified for acute aquatic toxicity. The substance is not readily biodegradable and chronic studies are available for all 3 species, with Daphnia being the most sensitive. The Daphnia reproduction study NOEC of 0.595 mg/L supports a Chronic 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.
