The pigment is expensive, especially when volume prices of systems are used. Most paint and ink companies buy raw materials per weight and sell their products by volume. As TiO2 has a relatively high density, ρ ≈ 4 g/cm3, the raw material contributes substantially to the volume price of a system.Finally, research has shown that titanium dioxide nanoparticles do not pass the first layer of the skin — the stratum corneum — and are not carcinogenic (7Trusted Source, 15Trusted Source).
Titanium dioxide is used a food colour (E171) and, as with all food colours, its technological function is to make food more visually appealing, to give colour to food that would otherwise be colourless, or to restore the original appearance of food. Titanium dioxide is also present in cosmetics, paints, and medicines.
Data availability statement
- Leading TiO2 producers include companies such as Chemours, Tronox, Cristal Global, Venator Materials PLC (formerly known as Huntsman), and Kronos Worldwide. These corporations often have multiple production sites around the globe, ensuring a steady supply chain for this critical material These corporations often have multiple production sites around the globe, ensuring a steady supply chain for this critical material

hitox tio2 manufacturers. They invest heavily in research and development to create more efficient production processes and higher quality TiO2 products.
- The market for titanium dioxide coatings is dynamic and subject to fluctuations in demand from various industries. Exporters must stay informed about global trends and adapt to changes, such as advancements in technology or shifts in consumer preferences. They must also be prepared to navigate challenges like international tariffs and transportation costs which can affect the pricing and availability of their products.

lithopone and titanium dioxide. The production process for TiO2 involves the use of hazardous chemicals, and its disposal can be problematic. Additionally, TiO2 has a tendency to agglomerate, which can affect its performance in certain applications.
Because of their small size, nanoparticles may have unique physical and chemical properties. These properties may cause them to interact with living systems differently than larger materials with the same chemical composition (also known as bulk materials).
- In addition to these factors, ceramic manufacturers should also consider the supplier's commitment to environmental sustainability. Titanium dioxide production can have significant environmental impacts, so it is important to choose a supplier that prioritizes eco-friendly practices and minimizes its carbon footprint.

The safety of the food additive E 171 was re-evaluated by the EFSA ANS Panel in 2016 in the frame of Regulation (EU) No 257/2010, as part of the re-evaluation programme for food additives authorised in the EU before 20 January 2009.
In May 2021, the European Food Safety Authority (EFSA) published an opinion that stated that titanium dioxide can no longer be considered safe when used as a food additive.

This work confirms previous studies that show P-25 and other untreated anatase 377 nanoparticles should not be employed in sunscreens because the toxicity of P25TiO2NPs under UV radiation is significant.

Animal studies have shown that, when consumed as a food additive, titanium dioxide can induce intestinal inflammation.
Still, in 2016 Skittles publicly declared it would get rid of the chemical compound in its products, according to a press release at the time from the Center for Food Safety, which called the substance harmful and potentially poisonous. But the ingredient remains, according to the lawsuit, which alleges the candy company is misleading consumers by not having eliminated titanium dioxide.
