Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

NOEC (14 d) ≥ 2.9 mg/L (toxicity control from a standard biodegradation study according to OECD 301D)

Key value for chemical safety assessment

EC10 or NOEC for microorganisms:
2.9 mg/L

Additional information

No inhibition of the biodegradation process was recorded at a concentration of 2.9 mg/L in the toxicity control of a standard biodegradation study according to OECD 301D (GLP). Thus, in accordance with the Guidance on Information Requirements and Chemical Safety Assessment Chapter R.7b; Endpoint specific guidance (ECHA, 2017) a NOEC (14 d) of ≥ 2.9 mg/L was derived.
