In the same year (2019), the Netherlands Food and Consumer Product Safety Authority (NVWA) also delivered an opinion on possible health effects of food additive titanium dioxide, which highlighted the importance of examining immunotoxicological effects in addition to potential reprotoxicological effects.
When looking for titanium dioxide suppliers, it is crucial to consider factors such as product quality, pricing, and reliability. Many reputable companies specialize in the production and distribution of titanium dioxide, ensuring that customers receive a consistent and high-quality product. International trade also plays a significant role in China's titanium dioxide industry. The country exports large quantities of titanium dioxide worldwide, making it an important player in the global market. Trade agreements and international relationships are carefully managed to secure export channels and ensure stable supply chains.In an early study Jani et al. administred rutile TiO2 (500 nm) as a 0.1 ml of 2.5 % w/v suspension (12.5 mg/kg BW) to female Sprague Dawley rats, by oral gavage daily for 10 days and detected presence of particles in all the major gut associated lymphoid tissue as well as in distant organs such as the liver, spleen, lung and peritoneal tissue, but not in heart and kidney. The distribution and toxicity of nano- (25 nm, 80 nm) and submicron-sized (155 nm) TiO2 particles were evaluated in mice administered a large, single, oral dosing (5 g/kg BW) by gavage. In the animals that were sacrificed two weeks later, ICP-MS analysis showed that the particles were retained mainly in liver, spleen, kidney, and lung tissues, indicating that they can be transported to other tissues and organs after uptake by the gastrointestinal tract. Interestingly, although an extremely high dose was administrated, no acute toxicity was observed. In groups exposed to 80 nm and 155 nm particles, histopathological changes were observed in the liver, kidney and in the brain. The biochemical serum parameters also indicated liver, kidney and cardiovascular damage and were higher in mice treated with nano-sized (25 or 80 nm) TiO2 compared to submicron-sized (155 nm) TiO2. However, the main weaknesses of this study are the use of extremely high single dose and insufficient characterisation of the particles.
The chloride process involves the chlorination of titanium ore to produce titanium tetrachloride, which is then oxidized to form titanium dioxide. This method produces high-purity TiO2 but requires the use of highly toxic chlorine gas and generates hazardous waste products.In sunscreen, titanium dioxide is used as a barrier to keep the sun's ultraviolet (UV) rays from damaging your skin. It's processed into much smaller particles than what goes into food, called nanoparticles. In this form, it becomes transparent, and also absorbs UV light so it doesn't reach your skin.
One of the primary uses of titanium dioxide is in the production of pigments for paints, coatings, and plastics. Titanium dioxide is known for its excellent opacity, brightness, and whiteness, making it an ideal choice for creating vibrant and long-lasting colors. Manufacturers of titanium dioxide carefully control the particle size and crystal structure of the pigment to ensure consistent quality and performance.
Rutile titanium dioxide, also known as TiO2, is a widely used pigment in various industries including paints, coatings, plastics, and cosmetics. As a key ingredient in many everyday products, it is important to source this material from a reliable and reputable supplier to ensure high quality and consistent performance.
Price Dynamics. The Titanium Dioxide price in United States decreased during December 2018 to 2,770 USD per metric ton, which represents a decline of 7% compared to the previous month’s value. On a year-over-year basis, Titanium Dioxide prices in United States remained constant . Meanwhile, in Germany, the average price of Titanium Dioxide amounted to 3,720 USD per metric ton, from 3,460 USD per metric ton one year earlier. On a month-over-month basis, the Titanium Dioxide price in Germany is 11% higher than the price one month before.
In the electronics sector, Zinc Barium Sulphate is employed in the production of electronic components, benefiting from its excellent electrical insulation properties. It is also used as a dielectric material in capacitors and other electronic devices. Moreover, in agriculture, it is used as a source of essential minerals, zinc and barium, for plant nutrition.EFSA's evaluation is related to the risks of TiO2 used as a food additive, not to other uses.
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.
Apart from the cosmetics industry, the coatings and plastics industry is also expected to contribute significantly to the growth of titanium dioxide in 2023. Coatings made from titanium dioxide offer excellent hiding power, durability and weather resistance, making them ideal for outdoor applications. Demand for high-quality coatings is expected to surge as the construction and automotive industries expand. Titanium dioxide is at the forefront of providing aesthetic and protective coatings, making it an indispensable ingredient in the industry.

A European ban of titanium dioxide in food took effect in 2022, but it is still legal for use in food in the U.S.
