Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 acute toxicity towards Daphnia magna was investigated according to OECD TG 202 under GLP under static conditions. Daphnids were exposed to nominal concentrations of 0.14, 0.24, 0.43, 0.77, 1.4, 2.4, 4.3, 7.7 and 14 mg/l and observed for 48 hours. The analysis showed that the analytical concentrations are > 80% compared to the nominal. Therefore nominal concentrations were used to derive the 48h EC50 value: that is 1.5 mg/l.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.

This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
