Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The vapour pressure of the DTPA-K5 salt has been determined as 2.6 x10-5 Pa at 298 K. There is also one study available for a 35-38 wt% aqueous solution of Pentasodium DTPA.
Key value for chemical safety assessment
- Vapour pressure:
- 0 Pa
- at the temperature of:
- 298 K
Additional information
For a 35 -38 wt% purity (aqueous solution) Pentasodium DTPA solution the vapor pressure is 12.2 mmHg at 20 deg Celcius, it is therefore concluded that the vapour pressure of a 40 wt% aqueous solution of Pentapotassium DTPA will be close to this value. The vapour pressure of the DTPA-K5 salt has been determined as 2.6 x10-5 Pa at 298 K.
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.
