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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Due to the ionic structure no adsorption onto the organic fraction of soil, sediment or sludge is expected.
Key value for chemical safety assessment
- Koc at 20 °C:
- 11.4
Additional information
Due to the ionic structure under environmental relevant pH conditions, no adsorption onto the organic fraction of soil, sediment or slduge is expected. ED2A will under ambient conditions almost entirely be present in the salt form where it is chelated to cations present in the matrix. For EDTA it has been shown by Gardiner 1976 that metal complexes nor the free or protonated ligand itself could have been significantly adsorbed on the surfaces of the solids which is in agreement with the low log Kow of -4.79. In accordance with column 2 of REACH Annex VIII, a Adsoprtions-/Desporptions-Screening test (required in section 9.3.1) does not need to be conducted.
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.
