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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
No experimental data is available for triammonium hydrogen ethylenediaminetetraacetate. Read across to editic acid was done instead.
The vapour pressure of edetic acid was detemined to be 2E-012 hPa at 25°C according to Riedel and Plank.
Key value for chemical safety assessment
Additional information
The vapour pressure determined for the acid form of EDTA represents also a worst case (highest) value for its ammonium salts as it is belived that only the free acid can evaporate. In conclusion the value extrapolated for the free acid will also be used for the exposure calculations of the ammonium salts in the chemical safety report, reflecting a worst case assumption.
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.
