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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key value for chemical safety assessment
Additional information
Experimental data investigating the biodegradability of Fatty acids, C16-18 and C18-unsatd., ethyl esters (CAS 85049-36-1) are not available. The assessment was therefore based on a study conducted with the structural analogue substance Isopropyl oleate (CAS 112-11-8). The study was conducted according to OECD Guideline 301 B and GLP (Desmares-Koopmans, 1997). Non-adapted domestic activated sludge was used as inoculum. The biodegradation rate was estimated by measuring the CO2 evolution of the inoculum. After a test period of 28 days the substance was degraded by 100%. The 10-day window criterion was met. Based on the results of the read across study Fatty acids, C16-18 and C18-unsatd., ethyl esters (CAS 85049-36-1) is considered to be 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.
