Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The substance was not toxic to algae when tested according to OECD guideline 201 (Alga, Growth Inhibition Test), with a 72-hour EC50 value greater than 100 mg/L
EC50 (Algae, 72 hr, OECD 201): > 100 mg/L
NOEC (Algae, 72 h, OECD 201): 9.77 mg/L
LOEC (Algae, 72 h, OECD 201): 31.3 mg/L

Key value for chemical safety assessment

Additional information

Statistically significant differences to the control were determined at 31.3 and 100 mg/L. No EC50-values were determined due to the fact that the inhibitory effects were below 50%. Therefore the EC50-value for growth rate and yield was estimated to be > 100mg/L. The LOEC is estimated to be 31.3 mg/L, the NOAEC was determined to be 9.77 mg/L.
