Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

There is no biodegradation information available for the UVCB substance itself. However, ta major component of thesubstance, 2 -(2 -(2 -ethoxyethoxy)ethoxy)ethanol ,was found to be readily biodegradable in a guideline study in freshwater where the BOD28 was 92.1%. The biodegradation was also assessed at a number of concentrations using a non-adapted domestic sewage innoculum in a freshwater medium. Ready degradation was observed with a BOD20 of 71%. In a single study in saltwater using the same substance, evidence of biodegradation was seen with 22% degradation after 20 days. A reliable QSAR predicts that both this substance and the other major component, 3,6,9,12-tetraoxatetradecan-1-ol ,will be readily biodegradable. The available data leads to a reliable conclusion that 3,6,9,12-tetraoxatetradecan-1-ol will be readily biodegradable. Please see the read across justification attached to chapter 13 of the lead registrant dossier for further information on read across within the E series of glycol ethers.

The substance has a low octanol-water partition coefficient (log Kow = -0.7) and and is fully miscible in water. Based on these physical chemical properties, if released to water, the compound will remain in the water compartment. The substance has low potential for adsorption to soil or sediment.
