Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Description of key information
The test substance is acutely toxic to aquatic invetebrates.
Key value for chemical safety assessment
Additional information
The short-term toxicity to daphnids was tested in a study according to OECD Guideline 202 under GLP. The test was performed with an aqueous extract (eluate) of the test substance. The analytical recovery rate after 0 h and 48 h was in all analyzed test solutions below 80%. The effective concentrations mentioned in this report are based therefore on the median analytical recovery rate found for test item concentration 100 mg/L between 0 h and 48 h (i.e. a calculation factor of 0.0618 was applied to nominal concentrations). In this way a 48h-EC50 of 4.92 mg/L was determined based on measured concentrations (48h-EC50 = 79.8 mg/L based on nominal concentrations).
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.
