Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

Parent compound titanium tetrachloride hydrolyses in water fast via target compound titanium oxychloride, revealing eventually titanium dioxide (rutile), thus read across from titanium dioxide would be proposed. As no results are available for the adsorption/desorption of TiO2, read-across is proposed to Kp values based on available monitoring data for elemental Ti-concentration in water and corresponding sediment or suspended matter (no data are available for soil). These results reflect the water/solid equilibrium conditions for Ti in the environment, regardless the speciation of Ti. The available log Kp data indicate that sediments and soils represent the relevant sink for the analogue materials and the target chemical. The Kd reflects the total titanium concentration ratio in equilibrium for all titanium compounds under environmental conditions, where 12 °C are assumed. In the risk assessment and based on field observed values, the partition coefficients log Kp susp 2.36, and log Kp sed 4.566 (median derived from several literature sources) are used.
