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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Key value for chemical safety assessment
Additional information
No experimental studies investigating the phototransformation in air of diethyleneglycol diformate (CAS 120570-77-6) are available. Results from AOPWIN v1.92 indicate that diethyleneglycol diformate is susceptible to indirect photodegradation in air (Müller, 2011). The estimated half-life for the reaction with OH-radicals is 21.765 h (24 h day; OH-concentration: 0.5E+06 OH/cm³). Moreover, diethyleneglycol diformate is not expected to be present in the atmosphere in high concentrations based on the and low volatilisation potential from water indicated by a Henry’s Law Constant of < 1 Pa m³/mole and indicated by a vapour pressure of 14.18 Pa.
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.
