Justification for data waiving:

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.
