Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Several biodegradation screening tests are available, which have investigated the ready- and inherent biodegradability of the tetraethylene glycol and category members. In one study, rapid biodegradation of tetraethylene glycol was observed which was sufficient to indicate ready biodegradability according to OECD guidelines. In the OECD 301A study of BASF AG, 90 - 100 % removal of dissolved organic carbon (DOC) as the test substance was observed within 20 days. Other supporting studies show potential for extensive degradation of the substance by various wastewater-derived microbial inocula. The rates and extents of degradation have been shown to increase with acclimation (prior exposure) of microorganisms to the substance.
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.
