Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
After evaporation or exposure to the air, Diammonium dihydrogen ethylenediaminetetraacetate (EDTA-(NH4)2H2) will be rapidly degraded by photochemical processes. However, photodegradation is not considered to be an important environmental fate process, since the substance is not expected to evaporate into the atmosphere due to the low vapor pressure. Abiotic hydrolysis is not relevant, since neither strong acids nor alkalis cause any degradation. However, available data indicate that EDTA species, especially iron complexes, are to a certain degree photolysable in water and soil.
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.
