Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Lanthanum carbonate is an inorganic substance, which is poorly water soluble. Therefore, biodegradation is not applicable.
At acidic conditions the substance trends to hydrolyse, a release of free Lanthanum ions and carbon dioxide is to be expected in a relevant amount at pH < 4, or bicarbonate if excess of carbon dioxid exists. At pH values above 6, salt hydrolysis can also occur, forming Lanthanum bicarbonate and insoluble Lanthanum hydroxide with increasing pH value. However, with respect to the poor water solubility of the test item, removal of lanthanum carbonate through hydrolysis process is negligible.
Since La+++ is a stable oxidation state of lanthanum compounds, an oxidation/reduction degradation is also not expected.
Therefore, the substance is considered to be abiotic stable under the normal environmental condition (pH, temperature).
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.
