Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 disodium persulfate at 25 °C was estimated at 6.07E-30 mm Hg corresponding to 8.09E-28 Pa using the Modified Grain Method of US EPA v4.0. A default value of 1E-6 Pa was used for further risk assessment.
Key value for chemical safety assessment
- Vapour pressure:
- 0 Pa
- at the temperature of:
- 25 °C
Additional information
As the available experimental methods allow a determination of vapour pressure down to 1E-5 Pa only, no meaningful experimental determination of the vapour pressure for disodium persulfate is possible.
Therefore, in accordance with the respective EC method A.4 (440/2008/EC) no experimental determination of the vapour pressure was carried out. Notably, inorganic chemicals are outside of the EPIWIN (v4.0) domain. Nevertheless, the vapour pressure of disodium persulfate is very low.
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.
