Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
