Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Biotic degradation :
The substance is considered to be readily biodegradable as demonstrated in the OECD 301F test performed with the registered substance N-[(9Z)-octadec-9-en-1-yl]propane-1,3-diaminium di[(9Z)-octadec-9-enoate] (CAS No. 3410-91-5, old CAS No. 40027-38-1) (Gancet 2004, GLP, reliability 2). Moreover another key study demonstrates that the diamine part is readily biodegradable according to an OECD 301D study (N-[(9Z)-octadec-9-en-1-yl]propane-1,3-diamine, CAS 7173-62-8) (van Ginkel 2008, GLP, reliability 1). As a supporting study, degradation according to OECD 301D test has been performed with an analogue substance,N-C16-C18-alkyl-(evennumbered, C18 unsaturated) propane-1,3-diaminium di[(9Z)-octadec-9-enoate] (CAS No. 1307863-78-0; old CAS No. 61791-53-5) (van Ginkel 2010, GLP, reliability 1).
The registered substance is a salt of one mole of N-[(9Z)-octadec-9 -en-1 -yl]propane-1,3 -diaminium compounded with two moles of (9Z)-octadec-9 -enoate (Oleic acid). The other chemical part of the registered salt, the fatty acids are predicted to be readily biodegradable according to the Biowin prediction (see QSAR in the supporting study). Taken altogether, the results allow to consider the registered substance and its both moiety are 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.
