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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
2 key studies available, 1 study using a 35 - 38% solution of Pentasodium DTPA and 1 study using a solid, powder form of Pentasodium DTPA at 90% purity.
Key value for chemical safety assessment
- Relative density at 20C:
- 600
Additional information
The substance in an aqueous solution (35 -38 wt%) has a relative density of 1.3. When in solid form (90% purity) the substance has a bulk density of ca 600 g/l.
A publish study show density for crystal Tetrasodium EDTA (CAS# 64 -02-8) is 1.67g/cm3. Since Tetrasodium ETDA and Pentasodium DTPA are pretty close in structure, this number can be used to estimate for the density of pentasodium DTPA.
For the purposes of registration it is concluded that bulk density of Pentasodium DTPA 90% purity is ca 600g/l. In crystal form, its density is estimated around 1.67g/cm3
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).
