Description of key information
Barium sulfate in nanoform is an inorganic sulfate which dissolves (to an extent and more so in the lower environmentally relevant pH range) in water to release barium cations that are of monoatomic nature. Hence, hydrolysis as defined by IUPAC (1994) is not possible. Furthermore, inorganic substances such as barium sulfate in nanoform cannot degrade or decompose but can be transformed e.g. by oxidation, reduction, speciation, precipitation. Thus, experimental data or other adequate and reliable information about the rate of hydrolysis, the extent of hydrolysis or the rate and extent of hydrolysis in different environments of barium sulfate in nanoform cannot be generated.
Key value for chemical safety assessment
Additional information
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.
