Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
No reliable results are available for the bioaccumulation of synthetic rutile in aquatic or terrestrial organisms. Therefore, read-across is proposed to reliable results for the bioaccumulation of TiO2 in fish and Ti metal in plants and corresponding soil or sediment samples. Ti concentrations in the fish tissues stayed constant over the concentration range of TiO2 in water tested (0-1 mg TiO2/L), resulting in decreasing BCF with increasing TiO2 concentrations in water. Reliable BSAF factors for plants vary between 0.0002 to 0.0008 kg/kg and point to the absence of bioaccumulation of Ti in plants. Therefore, synthetic rutile is not considered as bioaccumulative.
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.
