Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 48h-EC50 value based on nominal concentrations was 602 mg/L.
Key value for chemical safety assessment
Additional information
Two short-term studies, valid without restrictions, with invertebrates are available.
The final test (key study) was conducted under semi-static (24 hour renewa1) conditions (Jenkins, 1989). Daphnia were exposed to five concentrations in the range 100 to 1000 mg/L.
The pH of each was adjusted to approx. 7.0 before the addition of the daphnids. The 48h-EC50 value based on nominal concentrations was estimated to be 602 mg/L. This value is supported by a static test with Daphnia magna (Jenkins, 1991), which gave an 48h-EC50 of 687 mg/L at a pH of approx. 7.0.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.
