Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Phototransformation in air
Oxydiethylene bis(chloroformate) and its hydrolysis product diethylene glycol will be rapidly degraded by photochemical processes after evaporation or exposure to air. This estimation refers to dry air. In mist, rain, droplets and aerosols, hydrolysis will be the major fate process in air due to the short half-life of the chloroformate in aqueous solutions.
Hydrolysis
Oxydiethylene bis(chloroformate) rapidly hydrolyses in contact with water.
Hydrolysis of its transformation product diethylene glycol is not expected according to structural properties.
Biodegradability
Oxydiethylene bis(chloroformate) rapidly hydrolysis in contact with water; therefore, the assessment of its biodegradability is not relevant.
Its hydrolysis product diethylene glycol is readily biodegradable, but failing the 10-d window.
Biodegradation does not apply to the inorganic hydrolysis products (HCl and CO2).
Adsorption
It can be concluded that adsorption of oxydiethylene bis(chloroformate) as well as its hydrolysis product diethylene glycol to the solid soil phase are not to be expected.
Henry’s Law Constant
Oxidiethylene bis(chloroformate) rapidly hydrolyses in contact with water; therefore, the assessment of the parent compound is of low relevance. Oxydiethylene bis(chloroformate) as well as its hydrolysis product diethylene glycol will not evaporate into the atmosphere from the water surface.
Environmental distribution
Over time, the substance and its hydrolysis product diethylene glycol will preferentially distribute into the compartment water (100%).
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.
