Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Titanium tetrachloride is not stable under environmental conditions. It hydrolyses rapidly to finally titanium dioxide (CAS 13463-67-7) and hydrogen chloride (CAS 7647-01-0), which dissociates into naturally in high background concentrations occurring ions. The environmental fate of titanium dioxide is likely to be comparable to the naturally occurring mineral rutile, which is inert in the environment like the hydrogen chloride and its dissociation products.

In conclusion rapid hydrolysis of titanium tetrachloride in contact with water or humidity in air or soil leads to transformation into environmentally occurring inorganic inert compounds. The environmental hazard assessment needs to be based on these transformation products.
