Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Fatty acids, C16-18, esters with pentaerythritol (CAS-No. 85116-93-4) is readily biodegradable according to OECD criteria.
Key value for chemical safety assessment
Additional information
Two studies, investigating the ready biodegradability, were used as read across for Fatty acids, C16-18, esters with pentaerythritol (CAS-No. 85116-93-4). The test substances in these studies are structurally and composition related to Fatty acids, C16-18, esters with pentaerythritol (CAS-No. 85116-93-4). In the first study (Desmares-Koopmans, 1997) the biodegradation of Pentaerythritol tetraoleate (CAS-No. 19321-40-5) was tested in a CO2 Evolution Test according to OECD 301B using domestic activated sludge as inoculum. At test termination after 28 days the substance was degraded > 60% and the 10 -day-window was fulfilled. Thus, the read across substance is readily biodegradable according to OECD criteria. In the second study (Kuester and Wierich, 2000) the biodegradation of 2,2-bis(hydroxymethyl)-1,3-propanediyl dioleate (CAS-No. 25151 -96 -6) was tested in a Bodis-Test according to ISO 10708 using sewage effluent as inoculum. At test termination after 28 days the substance was degraded > 60% and the 14 -day-window was reached. Therefore, this substance is readily biodegradable according to ISO criteria. A conclusion by analogue approach has been applied. Based on the analogy it can be concluded that Fatty acids, C16-18, esters with pentaerythritol (CAS-No.85116-93-4) is also 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.
