Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
EC10 (3 h): 580 mg/L based on the respiration rate of activated sludge microorganisms (OECD 209)
Key value for chemical safety assessment
- EC10 or NOEC for microorganisms:
- 580 mg/L
Additional information
One experimental study investigating the inhibition of the respiration of diethyleneglycol diformate (CAS 120570-77-6) to activated sludge microorganisms is available (Roulstone, 2012). The study was conducted according to OECD 209 under GLP conditions using activated sludge from a sewage treatment plant treating predominantly domestic sewage. Five concentrations up to 1000 mg/L (nominal) were tested. After 3 h contact time diethyleneglycol diformate resulted in an EC10 of 580 mg/L based on the respiration rate.
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.
