REACH is a European Union-wide regulation – in place since 2007 – to protect human health and the environment from any potential risks posed by chemicals, while maintaining and enhancing the competitiveness of Europe’s chemicals industry. This regulation applies to all chemical substances.

REACH stands for Registration, Evaluation, Authorisation and Restriction of Chemicals. The policy also seeks to reduce research duplication and promote alternative hazard assessment methods.

Any company manufacturing or importing a chemical – in quantities of one tonne or more each year – has to register that substance under REACH. Registration includes technical information about a chemical and guidance on proper handling. Only substances evaluated to pose a risk to health or the environment are subject to any restrictions or authorisation procedures.

Leading European manufacturers and suppliers of titanium dioxide have formed the Titanium Dioxide Industry Consortium (TDIC) to manage REACH registration of TiO2 and related substances produced in its manufacture. Titanium dioxide is not subject to any restrictions or authorisations under REACH.

TDIC also liaises with other registrants of key raw materials and substance information exchange forums (SIEF). A SIEF is a requirement of REACH in order for registrants of substances to fulfil the obligations of REACH. This includes forming agreement between companies on classification and labelling, and enabling the sharing of data and research.

As a widely produced and used substance, the work of TDIC and members of the large TiO2 SIEF provides comprehensive information about titanium dioxide and related substances. It helps companies that use titanium dioxide products to meet their regulatory obligations.

The substances covered by REACH and managed by the TDIC are:

Titanium dioxide (CAS 13463-67-7, EINECS 236-675-5) – visit the What is Titanium Dioxide? section of this website for more information about TiO2 and the production process.

Titanium tetrachloride (CAS 7550-45-0, EINECS 231-441-9) – a dense, colourless and volatile liquid formed in the chloride process used to produce TiO2. Titanium tetrachloride (TiCl4) using the correct precautions can be safely handled in the production process and it is not used in consumer applications. It is an important part of the production of TiO2 and the metal titanium.

Titanium oxide sulphate (CAS 13825-74-6, EINECS 237-523-0) – has the formula TiOSO4 and may be referred to as titanium oxygen sulfate. It is produced in the sulphate process for producing TiO2.

Dichloride titanium oxide (CAS 13780-39-7, EINECS 237-430-5) – has the formula TiOCl2 and is a chemical produced in the chloride process for producing titanium dioxide.

Disodium titanate (CAS 12034-34-3, EINECS 234-802-9) – this has the formula Na2O3Ti; it is a related substance that has electrochemical and electroceramic uses.
