Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Henry's Law Constant does not need to be determined at this level of registration. Distribution modelling and other distribution data does not need to be obtained.

In accordance with Regulation (No) 1907/2006 (REACH) Annex XI, the adsorption coefficient could not be determined using the technique specified in the OECD draft guideline( July 1997): Estimation of the Adsorption Coefficient (Koc) on Soil and on Sewage Sludge using High Performance Liquid Chromatography (HPLC). This is due to the low solubility of the substance in water and organic solvents.

Furthermore, the substance is not expected to have the potential for adsorption.

Titanium has a strong tendency to partition into the solid phase as it has a strong tendency to form aggregates, and exist in the solid phase rather than form free ions in solution. Consequently, partitioning of Titanium containing substances tend not to be dependent on pH or redox conditions (which can often affect speciation and behaviour in the case of other metals). As such, the adsorption values derived from literature publications for total Titanium in the field can also be considered as appropriate for use with this substance.
