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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
CaSi and the (slowly) soluble constituents, pure calcium (as Ca2+) and pure amorphous silica are known to be non toxic substances in fresh water and marine sediments.
Key value for chemical safety assessment
Additional information
CaSi alloys are poorly water soluble inorganic substances and therefore can enter sediments if released directly to aquatic environment. Adsorption of soluble constituent to sediment is not likely or remarkable. Pure calcium (as Ca2+) and pure amorphous silica are known to be non toxic substances in fresh water and marine sediments.
Substances that are potentially capable of depositing on sediments to a significant extent have to be tested and assessed for toxicity to sediment-dwelling organisms. Sediment testing is not regarded necessary or important for CaSi.
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.
