Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
No biodegradation studies have been performed with the registration substance. However, reliable data are available for related Fischer-Tropsch process-derived materials in the relevant carbon number range (GTL Solvent GS160 and GTL Solvent GS190).
In an OECD 301F manometric respirometry test conducted in compliance with GLP, Hydrocarbons, C9-C12, n-alkanes, isoalkanes, <2% aromatics (GTL Solvent GS190) attained 80% degradation in 28 days (Vryenhoef, 2014a). The 10-day window criterion is not applicable for complex substances where sequential degradation of the constituents takes place (REACH guidance R.7b ECHA, 2017). The substance was therefore concluded to be readily biodegradable.
Hydrocarbons, C8-C11, n-alkanes, isoalkanes, <2% aromatics has been tested in an OECD 301F (manometric respirometry) test conducted in compliance with GLP (Best, 2014). The test substance attained 73% biodegradation in 28 days and was therefore considered to be readily biodegradable.
As both these studies are considered to be reliable, and are used as weight of evidence to determine that Hydrocarbons, C9-C11, n-alkanes, isoalkanes, <2% aromatics is readily biodegradable.
Additional information
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.
