Description of key information

DEHA is not inhibitory to micro-organisms in an OECD 301F test at a concentration of 100 mg/L.

Key value for chemical safety assessment

EC10 or NOEC for microorganisms:
100 mg/L

Additional information

Gancet (2011) is a GLP-compliant, 28 days, static freshwater study following OECD guideline 301F test. A toxicity control flask showed that micro-organisms were not inhibited at a concentration of DEHA of 100 mg/L. Therefore the biodegradation test is considered reliable and is suitable for use to determine the toxiicty toward microorganisms.
