Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Executive summary:

Lowest NOEC value is 20 mg/kg, whereas density is 1.64 kg/m3 (0.00164 kg/L)

NOEC 20 mg/kg = 0.0328 mg/L

Description of key information

NOEC for marine water invertabrates has been recalculated from NOEC mg/kg based on substance density (publication nr 25).

Lowest NOEC value is 20 mg/kg, whereas density is 1.64 kg/m3 (0.00164 kg/L)

NOEC 20 mg/kg = 0.0328 mg/L

Key value for chemical safety assessment
