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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Phototransformation in air
Estimated half-lives for the components of this UVCB substance range from 3.1 to 9.4 hours.
Hydrolysis
In accordance with Column 2 of REACH Annex VIII, the study does not need to be conducted as the substance is readily biodegradable. Ether bonds are stable and do not hydrolyse to a significant extent at environmentally relevant conditions.
Biodegradation
Within 28 days, a degradation of 75 % was determined for Diethyleneglycol, propoxylated according to OECD Guideline 301F; and hence Diethyleneglycol, propoxylated is considered to be "Readily Biodegradable" (Currenta, 2009).
Bioaccumulation
With a log Kow ≤3, the substance can be considered to have a low potential for bioaccumulation.
Adsorption/desorption
In accordance with Column 2 of REACH Annex IX, the study does not need to be conducted as the substance can be expected to have a low potential for sorption (log Kow ≤3). The estimated Koc value for homologous components of this UVCB substance range is 10 L/kg for the lowest (least sorptive) and highest (most sorptive) molecular weight homologues. The components of this UVCB substance can be regarded as having low affinity for adsorption to soils and activated sludge biosolids.
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.
