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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The adsorption coefficient can not be determined for technical reasons.
Key value for chemical safety assessment
Additional information
- The water solubility of Lithium titanium oxide is <0.25 mg / L at 20 °C, not sufficient to perform a batch test.
- The test substance is an inorganic compound. There is no method to distinguish between the different species of Li or Ti possibly generated in the aqueous phase or adsorbed on the soil and its parent compound.
- The water solubility of Lithium titanium oxide is depending on the loading rate. The water solubility of the complete compound is significantly higher if it is calculated from the Li-results compared to the Ti-results. This is interpreted either that not the unchanged test substance dissolves in water or that soluble impurities are present.
- Therefore the pre-conditions for applying the EU- or OECD-methods are not fulfilled.
- The calculation of the adsorption coefficient from the octanol-water partition coefficient is not possible because the calculation is not applicable to inorganic compounds.
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.
