Registration Dossier
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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

EC number: 293-671-6 | CAS number: 91081-64-0 Slag produced during ilmenite smelting (ore or sand). Consists primarly of TiO2, FeO, Al2O3, SiO2, MgO and other metal oxides.

Description of key information
Reliable data on adsorption/desorption, reporting distribution coefficients (Kd values), are available for sediment and suspended matter (read-across approach with titanium). Roychoudhury and Starke (2006) reported a mean Log Kd value of 4.61 L/kg dw in freshwater river sediments while Vesely et al. (2001) reported a median Log Kd value of 5.36 L/kg dw for freshwater suspended solids.
Key value for chemical safety assessment
Additional information
Reliable data for distribution of Ti between solid and solution phase are available for sediment and suspended matter, based on monitoring data of elemental Ti in the different environmental compartments. These results can be used in a read-across approach for UGI products, since it is assumed that at equilibrium UGI-derived Ti will have the same fate and distribution as the ambient Ti in the environment.
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.
