Description of key information

DT50: 1.24 d (pH7) and 2.98 h (pH8) (HYDROWIN v2.00)

Key value for chemical safety assessment

Additional information

No experimental studies investigating the abiotic hydrolysis of ethylene diformate (CAS 629-15-2) are available. Reliable QSAR calculations (HYDROWIN v2.00) resulted in DT50 values of 1.24 d at pH 7 and 2.98 h at pH 8 (Müller, 2011). Thus, the substance will hydrolyse to the expected hydrolysis products ethylene glycol and formic acid once it gets in contact with water. Further analytical investigations in the available ecotoxicological studies resulted in DT50 values of 4 h in standard algae medium (OECD 201; Vryenhoef, 2013) and 11 h in standard daphnia medium (OECD 202; Vryenhoef, 2012) showing that the substance is susceptible to hydrolysis.
