Additional information
Short-term toxicity to aquatic invertebrates. Key study: Method according to OECD 202. GLP study. The 48h-EC50 of the test item in Daphnia magna was found to be 29.93 mg/L (measured, geom. mean), the NOEC = 12.76 mg/L, and the LOEC = 18.50 mg/L, based on mobility.
Short-term toxicity to aquatic algae and cyanobacteria. Key study. Method according to OECD 201. GLP study. The 72h-EC50 in green algae Pseudokirchneriella subcapitata was found to be 7.51 mg/L (measured, geometric mean), and the EC10 was 1.97 mg/L (measured, geometric mean), based on growth rate.
Conclusion on classification
Based on available data (48h-EC50 in daphnids = 29.93 mg/L, 72h-EC50 in algae = 7.51 mg/L, 72h-EC10 in algae = 1.97 mg/L) and since the substance is readily biodegradable, with a Log Kow < 4, the test item is not classified for aquatic toxicity, according to 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.
