Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
CaSi is an inorganic substance and it is not biodegradable in a sense of microbiological utilization of the substance as a source of carbon and energy. The substance is expected to be highly resistant to microbiological activity and sufficient evidence exists to show that no biodegradability studies are needed for this substance. However, depending on conditions, the (dissolved ionic/neutral Ca (II) Si (IV) )constituents may still be subject to biologically mediated processes leading to biotransformations. Calcium is an essential element and nutrient for all living organisms.
Dissolved silica (as Si(OH)4) is still subject to biologically mediated processes leading to transformations of biologically absorbed silica. However, for instance Si is not known to be associated covalently to any organic molecules in biological processes (Craig, 1986). These processes are discussed in more detail under chapters dealing with bioaccumulation where a short description of biologically mediated transformation processes is given.Craig P.J., (ed) 1986, Organometallic compounds in the environment, Wiley & Sons, NY
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.
