Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Short-term toxicity to aquatic invertebrates

Description of key information
The 24h-EC50 of the substance in Daphnia magna is > maximum solubility of the substance in test medium.
Key value for chemical safety assessment
Additional information
The toxicity to aquatic invertebrates was examined in a study according to OECD TG 202 (1984) and in compliance with GLP criteria. Groups of daphnids (2 replicates of 10) were exposed to test item concentrations of 0 (control), 1000 mg/L filtered (i.e. saturated solution), and 1000 mg/L unfiltered (i.e. supersaturated solution) for 24 hours under static conditions. No test substance analysis was performed. After the exposure period, a 15% immobility (3/20) in the saturated solution and no immobility (0/20) in the supersaturated solution was oberved. Based on these findings, the 24h-EC50 in Daphnia magna was determined to be higher than the limit of solubility in test medium at a nominal loading rate of 1000 mg/L.
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.
