Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
No biodegradation data is available on the multi-constituent substance itself. Experimental data is available on one major components however and a closely related member of the homologous series. In a guideline study, the substance 2-(2-(2-methoxyethoxy)ethoxy)ethanol was found to be readily biodegradable and met the 10 day window. Full degradation occured within 13 days. In a guideline study, the substance 3, 6, 9, 12-tetraoxotridecanol was found to be readily biodegradable but did not meet the 10 day window. A QSAR suggests that both of these substances and PentaEGME are readily biodegradable, but that there is a slight trend towards slower degradation with increasing molecular weight. A conservative conclusion therefore, based on the experimental data available and the trends seen with the QSAR, is that the multi-constituent substance is readily biodegradable but may not meet the 10 day window.
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.
