Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Triethylphosphat is reported to have a water solubility of 500 g/L at. 25°C. (Handbook of Aqueous Solubility Data)

Key value for chemical safety assessment

Water solubility:
500 g/L
at the temperature of:
25 °C

Additional information

Yalkowsky et al (2003) reports the water solubility of the substance to be 500 g/L at 25 °C. This handbook is considered to be a reliable source, therefore it is regarded as a key study.

As a phosphate ester, the structure contains no ionisable feature, therefore no impact of pH is anticipated.
