Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 and ammonium sulfate)
Key value for chemical safety assessment
Additional information
The vapour pressure of the whole substance is read-across from available data for citric acid and ammonium sulfate. A vapour pressure of 2.2E-06 Pa at 25°C was reported for citric acid in a collection of reliable data which has been subject to peer-review and in which the original sources are traceable (Daubert 1991). Similarly, vapour pressure of 4.1E-07 Pa at 25°C was reported for ammonia over solid ammonium sulfate in a peer-reviewed source (OECD 2004). The results are considered to be reliable and are used as weight of evidence. The vapour pressure of the whole substance is expected to be lower than that of citric acid and ammonium sulfate, therefore, the vapour pressure of the substance is considered to be negligible (<<1E-06 Pa).
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.
