Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 potassium sorbate was determined using the effusion method vapour pressure balance as described by the OECD Guideline for testing of chemical No:104 and EU MEthod A.4.
Key value for chemical safety assessment
- Vapour pressure:
- 0 hPa
- at the temperature of:
- 20 °C
Additional information
Due to the fact that no detectable vapour pressure could be determined by the experimental method in a temperature range of 20 to 148 °C, the vapour pressures were calculated based on conservative estimates using the Antoine equation as
p(20 °C) =< 1.0 * 10^-7hPa
p(25 °C) =< 1.0 * 10 ^-7hPa
p(50 °C) =< 1.0 * 10 ^-7hPa.
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.
