Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
EC50 (48 h): 36.0 mg/L based on mobility of Daphnia magna (EU method C.2).
Key value for chemical safety assessment
Fresh water invertebrates
Fresh water invertebrates
- Effect concentration:
- 36 mg/L
Additional information
The toxicity of the test item to invertebrates was determined in a static test performed according to EU method C.2 and GLP. Individuals of Daphnia magna were exposed to nominal test concentrations of 14, 28 and 56 mg/L, equivalent to geometric mean measured concentrations of 18, 31.5 and 54 mg/L. The test concentrations were analysed by TOC determination daily. After 48 h 100% immobility was observed at 54 mg/L whereas 0% immobility was recorded at 18 mg/L. The EC50 (48 h) was calculated at 36 mg/L (measured).
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.
