Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 (48h): > 150 mg/L

Key value for chemical safety assessment

Fresh water invertebrates

Fresh water invertebrates
Effect concentration:
150 mg/L

Additional information

A limit test on Daphnia Magna has been performed (Stahl, 1996), showing no mortality at the tested concentration of 180 mg/L. Since the sample concentration is 83% of the nominal concentration, the EC50 has been set at 150 mg/L
