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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
This study is not technically feasible with this material. Results from water solubility and hydrolysis tests imply that this substance does not dissociate and application of the method would be difficult in practice.
Key value for chemical safety assessment
Additional information
This substance is insoluble in water and dissociation does not occur at normal pH values. The structure of the material is that of an inorganic polymer and takes the form of a layered sheet of magnesium and silicate molecules containing some lithium cations replacing a portion of the magnesium ions in the lattice. The silicate lattice has a slight negative charge which is balanced by sodium ions. On dispersion in water some free sodium and fluoride ions can be measured but these are from a low level of sodium sulphate and fluoride impurity remaining from the process and not from the substance itself
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.
