Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 substance itself. Data is available on two major components however. 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. An analysis of the three components of this substance (that represent 3 adjacent molecule in the homologous series and that define a major part of this UVCB/multicomponent substance) using the BIOWIN QSAR shows that all are predicted to be readily biodegradable. However, an analysis of the fragment descriptions suggests on a semi-quantitative basis that that breakdown may be slower with increasing molecular size. The QSAR is therefore supportive of the experimental data. A conservative conclusion that would cover all potential compositions is therefore that the substance is readily biodegradable but does not meet the 10 day window.
