Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
In the table below the acute aquatic toxicity data are summarised
| Species | Guideline | Result in mg/l | Remarks |
Pseudokirchneriella subcapitata |
OECD TG 201 |
EC50 growth rate > 0.31 based on geometric mean measured concentrations |
Key study, Rel. 1. No robust EC10-value could be determined for growth rate. The ErC50 is >0.31 mg/L based on the fact that only 21% inhibition of growth rate was observed at this concentration. |
Daphnia magna |
OECD TG 202 |
EC50 48h = 0.33 based on mean measured concentrations |
Key study, Rel 1. |
Additional information
In the study with algae, the geometric mean measured concentrations showed no dose-response curve due to the fact that average exposure concentrations were similar at the three lowest WAFs, i.e. 0.026-0.044 mg/L and at the three highest WAFs (0.31-0.41 mg/L).
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.
