Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
According to section 1 REACH Annex XI a study does not need to be conducted, as the substance is marketed as an aqueous solution only and the vapour pressure is expected to be in the same range of pure water. The data from manufactures proved this expectation and the vapour pressure of SMBT aqueous solutions is very close to 23 hPa (20°C).
Key value for chemical safety assessment
Additional information
A vapour pressure of 32 hPa (25°C) was reported by Flexsys for a 45 - 50 % solution; and 107 hPa (50°C) was reported by Lanxess for 50 % solution and 23 hPa for 30 % solution.
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.
