Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
Reliable measured data show that Guerbet alcohols of chain lengths up to C20 are readily biodegradable. At carbon chain length of C16 the data show that the pass level for ready biodegradation was reached within the 10-day window with removal levels up to 96%. Chain lengths of C20 achieved ready test pass levels but not in all cases within the 10d window.
The data demonstrate a decrease in biodegradation rates with increasing chain length which could be associated with the decrease in water solubility and the resulting decrease in bioavailability. Therefore Guerbet alcohols with chain lengths of up to C20 are readily biodegradable.
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.
