Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Administrative data
Link to relevant study record(s)
Description of key information
The short term toxicity to aquatic invertebrates has been determined by a 48h Acute Immobilisation test on Daphnia Magna (OECD 202). As the test substance is insoluble in water (solubility < 1mg/L), extracts of a nominal concentration of 100mg/L have been chosen as test medium in a limit test. The EC50 has been determined to be >100mg/L (nominal).
Key value for chemical safety assessment
Fresh water invertebrates

Additional information
The study chosen as key study is valid for this endpoint as it has been performed according to GLP and OECD guideline 202 (Acute toxicity to aquatic invertebrates). cBN is insoluble in water (<1mg/L), therefore a LIMIT test with a nominal concentration of 100 mg cBN per litre is appropriate.
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.
