Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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


Pseudokirchneriella subcapitata


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).
