Titanium dioxide is predominantly used as a pigment in products such as paints, coatings, plastics, food, cosmetics, and paper. The ability of TiO2 to scatter light and provide a white color makes it an essential ingredient in achieving high-quality finishes in these applications. However, the production of titanium dioxide can be complex and costly, given that it involves raw materials such as ilmenite and rutile, as well as advanced processing technologies. Manufacturers are continuously striving to optimize costs without compromising quality, making the search for affordable suppliers a top priority for many businesses.
In the European domestic market, however, the cost support from increasing freight charges kept the valuation of imported volumes high, and the average CFR NWE discussions were assessed at USD 3800 per tonne in the fourth quarter of 2021.
All in all, Titanium Dioxide is a famous sunscreen agent and for good reason, it gives broad spectrum UV protection (best at UVB and UVA II), it's highly stable, and it has a good safety profile. It's definitely one of the best UV-filter agents we have today, especially in the US where new-generation Tinosorb filters are not (yet) approved.
When used as a base or colorant in a product, titanium dioxide becomes handy in formulas meant to offer a lot of brightness and opacity. Titanium dioxide is so pigmented, in fact, that it’s used not only in white and pastel-colored products but also in darker shades, as well.
It has an extremely high melting point of 1 843ºC and boiling point of 2 972ºC, so occurs naturally as a solid, and, even in its particle form, it is insoluble in water. TiO2 is also an insulator.

Anatase titanium dioxide is typically produced by the chloride process, which involves the chlorination of titanium ore to produce titanium tetrachloride Anatase titanium dioxide is typically produced by the chloride process, which involves the chlorination of titanium ore to produce titanium tetrachloriderutile and anatase titanium dioxide factory. The resulting gas is then reacted with oxygen to produce anatase titanium dioxide particles, which are collected and processed into the final product.The assessment was conducted following a rigorous methodology and taking into consideration many thousands of studies that have become available since EFSA’s previous assessment in 2016, including new scientific evidence and data on nanoparticles.
TiO2 has been well accepted in the food industry and can be found as the E171 additive in various food products, mainly for whitening and texture. It is present in some cottage and Mozzarella cheeses, horseradish cream and sauces, lemon curd, and in low-fat products such as skimmed milk and ice-cream. Even if the product is labelled as containing E171, no information is usually given about the quantity, particle size and particle structure. FDA claims that TiO2 may be safely used as a colour additive for colouring foods in quantities up to 1 % by weight of the food. Interestingly, TiO2 is frequently declared as a “natural colouring agent” and is therefore well accepted by consumers.

Titanium dioxide is a versatile material with a wide range of applications. Some of its most common uses include:

Titanium dioxide exists primarily in three crystalline forms rutile, anatase, and brookite. Among these, anatase is characterized by its unique electronic properties and higher photocatalytic activity, making it suitable for applications requiring enhanced light absorption and reactivity. Its ability to act as a photocatalyst enables the breakdown of organic pollutants, making it a valuable component in environmental remediation strategies.
On absorption of UV light, photo-generated titanium dioxide particles create singlet oxygen, superoxide anions (O2-) and hydroxyl radicals (OH-) that are potent free radicals (1,2). Irradiated particles of titanium dioxide can induce oxidative damage to DNA (2) which can lead to the development of mutant cells and skin cancers (3,4,5,6) and lipid peroxidation of essential functions on the cell membrane (7).
The US and Canada, however, approve the use of titanium dioxide as a food additive. Canada's recent review of titanium dioxide reconfirmed its safety and pointed out that many of the toxicity studies the EU reviewed were not relevant to the safety of titanium dioxide as a food ingredient, and that the ban is based on an abundance of caution and uncertainty.
