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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
According to Section 9.3.2 of Annex IX, bioaccumulation in aquatic species (preferably fish) does not need to be conducted if the substance has a low potential for bioaccumulation (for instance a log Kow ≤ 3) and/or a low potential to cross biological membranes. The target substance hydrolyses to form sulphuric acid and potassium sulphate (K+2SO42-), the source substances. A hydrolysis study was undertaken where the reaction of the test substance was followed using laser Raman spectroscopy. The study demonstrated that at 1 M concentration of test substance, it took 22 minutes for the reaction to run to completion. At a pH of 7.4, the hydrolysis products appeared to be entirely in the form of constituent ions including SO42-. Sulphate is an important component of living organisms and can be expected to be controlled by normal physiological processes (including uptake and excretion/elimination) in all living organisms. Therefore, the substance and its constituent ions have low potential for bioaccumulation beyond normal physiological limits in either aquatic or terrestrial organisms.
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.
