Additional information
Conclusion on classification
Short-term fish, Daphnia and algae toxicity studies are available on the test substance. Based on the results from the available studies, Daphnia has been identified to be the most sensitive species. The short-term 48 h EC50 value for the test substance in Daphnia was determined to be 25.8 mg/L (measured) and the long-term equivalent NOEC value from the algae study was at 38.15 mg/L (measured). Considering that the test substance is not readily biodegradable and based on the acute toxicity data, the test substance warrants an ‘Aquatic Chronic Cat. 3’ (H412: Harmful to aquatic life with long lasting effects) classification according to the EU CLP criteria (EC 1272/2008). However, based on long-term term data from the algae study, the test substance does not warrant any classification for chronic aquatic toxicity. Therefore, the more stringent classification as ‘Aquatic Chronic Cat. 3’ (H412: Harmful to aquatic life with long lasting effects) has been taken forward for the test substance.
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.
