Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

Daphnia short-term is the lowest definitive EC 50 value and therefore is the POD for the aquatic PNECs. As only short-term studies the highest AF were used in the derviations.

Conclusion on classification

Based on the lowest EC50 value of > 2.2 mg/L for acute daphnia and the fact that the substance is readily biodegradable but failing the 10 day window, the classification criteria of aquatic chronic 2 is assigned.
