Description of key information

No inhibition of the biodegradation process was recorded at a concentration of 2.9 mg/L in a standard biodegradation study according to EU Method C.4-E (GLP). Thus, in accordance with the Guidance on Information Requirements and Chemical Safety Assessment Chapter R.7b; Endpoint specific guidance (ECHA, 2014) a NOEC (14 d) of ≥ 2.9 mg/L was derived.

Key value for chemical safety assessment

EC10 or NOEC for microorganisms:
2.9 mg/L
