Description of key information

Additional information

Titanium nitride is an inorganic substance which is as such not biodegradable.

In addition, the substance is considered practically insoluble in water (23.8 µg Ti/L at 100 mg loading, pH 6 after 7 days in a transformation/dissolution test according to OECD Series on Testing and Assessment No. 29), and chemically stable. Therefore, adsorption/desorption testing is considered technically not feasible. Furthermore, titanium nitride is predicted not to be prone to hydrolysis hence testing is considered scientifically unjustified.
