Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC number: 310-080-1 | CAS number: 102242-49-9 The complex residue resulting from the vacuum distillation of C6-24 fatty alcohols which is derived from hydrogenation of C6-24 fatty acids methyl esters. It consists predominantly of satd. fatty alcohols having carbon numbers greater than C18, dimerization products, and long chain esters having carbon numbers greater than C32 and boils at > 250°C (482°F) at 10 torr.

Description of key information
In a study according to OECD Test Guideline 301B under GLP, the test substance was readily biodegradable.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
In the only available (and relevant) study, performed according to the OECD test guideline 301B, the ready biodegradability of the test substance was determined under GLP. In this aerobic test with activated sludge (domestic and non-adapted) the oxygen consumption was determined over 28 days with the two concentrations of 12.9 and 25.8 mg test substance/L. All validation criteria were fulfilled. On day 13 approx. 66% biodegradation was observed, while at the end of the study, the test substance was biodegraded to approx. 77%.
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.
