Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

log Koc= 3.1-4.4 (KOCWIN v2.00)

Key value for chemical safety assessment

Additional information

No experimental data investigating the adsorption potential of Fatty acids, C12-C14 (even numbered), methyl esters (CAS No. 308065-15-8) are available. Since the substance is a complex UVCB substance, QSAR calculations covering representative fatty acid components (C12 and C14) were performed with KOCWIN v2.00. The resulting log Koc values range from 3.1-3.8 (C12, MCI and log Kow method respectively) and 3.6-4.4 (C14, MCI and log Kow method)(López Parrón, 2011). These values indicate that Fatty acids, C12-C14 (even numbered), methyl esters is expected to exhibit potential for adsorption to organic soil and sediment particles.
