Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

A weight of evidence approach has been used to conclude on short-term toxicity to Daphnia.

From experimental data, EC50 values range from 39 mg/L at 24 hours to 13 mg/L at 72 hours (comparable with reported fish LC50-values), the most conservative value has been selected.

This is the predicted 72h Daphnia EC 50 = 13 mg/L.

Key value for chemical safety assessment

Fresh water invertebrates

Effect concentration:
13 mg/L

Additional information

From two available studies, EC50 values are in the range of 13 -20 mg/L (Bringmann & Kuehn, 1982; Hessov, 1975).
