Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Monoethanolamine and citric acid are the starting materials for the synthesis of tris[(2-hydroxyethyl)ammonium] citrate, and the only difference is that in tris[(2-hydroxyethyl)ammonium] citrate the substances are present in their ionic forms as a monoethanolamine cation and a citrate anion. It is expected that the ecotoxicological properties of tris[(2-hydroxyethyl)ammonium] citrate shall be governed by the properties of monoethanolamine and citric acid (for more details see reporting format for the analogue approach in Appendix A.2). Therefore, the Koc is calculated for tris[(2-hydroxyethyl)ammonium] citrate as well as for monoethanolamine and citric acid with KOCWIN™ v2.00 (U. S. EPA, 2008) using the Molecular Connectivity Index (for details see QMRF and QPRF see Appendix A.3). For tris[(2-hydroxyethyl)ammonium] citrate the calculated Koc value is 10 L/kg. For monoethanolamine and citric acid the Koc values are 1.167 and 10 L/kg, respectively.
No other data are available on the transport and distribution of monoethanolamine citrate in the environment.
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.
