Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Additional information
Since calcium sulfate is an inorganic substance, it does not undergo biodegradation i.e. microbial degradation to carbon dioxide and water, since it doesn’t contain any carbon or hydrogen atoms in its chemical formula. Calcium sulfate will therefore be degraded in the environment by means other than biodegradation. The ions will dissociate; calcium will be assimilated by species in the water and is necessary to maintain a good chemical balance in soils, water and plants and the sulfate will become part of the sulfur cycle or be assimilated by microorganisms and other species that require sulfate as an essential substance in their biological systems/ processes.
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.
