Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Vapour pressure: negligible (read-across from citric acid)

Key value for chemical safety assessment

Additional information

A vapour pressure value of 2.21E-6 Pa at 25°C for citric acid is reported in a collection of reliable data which has been subject to peer-review and in which the original data sources are traceable. The result is considered to be reliable. The vapour pressure of a metal salt is expected to be lower than that of the parent acid and, therefore, the vapour pressure of tripotassium citrate can be said to be negligible.
