Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Water solubility (DTPMP-xK): The substance is very soluble in water and has a water solubility value of 500 g/l at ambient conditions as described in a secondary source. 

Key value for chemical safety assessment

Additional information

The water solubility of DTPMP-xK was read across from the acid. The test substance was reported as miscible in water in a handbook (Gledhill 1992) which has been subject to peer-review and in which the original data sources are traceable. The result is considered to be reliable. Many commercial solutions at approx. 500 g/L are reported in company literature. The salt samples are expected to be more soluble than their corresponding acids. This is supported by available secondary sources which indicates the sodium salt to be miscible with water.

The original references were not available for review and no further information is available. The reliability of those results is not assignable.
