- Transparent TiO2 is produced through a proprietary process that involves the controlled hydrolysis and oxidation of titanium tetrachloride. The resulting particles are micronized to achieve the desired particle size and distribution, which is critical for achieving optimal transparency and color performance.

Even though it is one of the most-produced chemicals, the real and potential benefits of titanium dioxide are not without controversies. Dust inhalation may cause breathing problems. Titanium dioxide has been classified by the International Agency for Research on Cancer as an Group 2B carcinogen, a “possible carcinogen to humans,” based on studies of rats that inhaled the substance.
There are numerous manufacturers of titanium dioxide; the largest include Delaware-based Chemours (a spin-off of DuPont Chemical), Texas-based Kronos, and China-based Lomon Billions Group, all of which manufacture pigments for use in products like paints, coatings, and plastics. UK-based Venator is a major supplier of titanium dioxide used in food and cosmetics, along with paints, paper, plastic, and more. As a pigment, it is called Pigment White 6 (PW6), titanium white, or CI 77891. As a food additive, it is known as E171.
Production[edit]
Particle size: optimum particle size to produce maximum opacity is 200–300 nm.

Looking ahead to 2023, titanium dioxide will play a key role in various industries. The growth potential of this chemical is huge, and companies like Hebei Caiqing Material Technology Co., Ltd. are well positioned to meet the changing demands of the market. With its individual customization services and dedication to research and development, the company is well-positioned to meet the growing demand and contribute to the advancement of titanium dioxide applications worldwide. Whether in coatings or plastics, titanium dioxide brings innovation, protection and improved product performance to a wide range of customers around the world.
In the paper industry, TiO2 is used to create high-quality, bright white paper products. By adding TiO2 to pulp, paper manufacturers can improve the opacity, brightness, and printability of their products. TiO2 also enhances the lightfastness and aging resistance of paper, ensuring that it maintains its appearance and quality over time. With TiO2, paper products can achieve a superior level of whiteness and visual appeal.

Basic Information
In January 2022, the average price of domestic titanium dioxide in local Chinese marketplaces was 20,735 RMB/MT. Traders were more careful in purchasing goods and downstream industries purchased things on demand. As a result, the overall market demand for titanium dioxide was general.
Following the EU’s ban on E171, the FDA told the Guardian that, based on current evidence, titanium dioxide as a food additive is safe. “The available safety studies do not demonstrate safety concerns connected to the use of titanium dioxide as a color additive.”


Ability to scatter and absorb UV radiation makes TiO2 a crucial ingredient for sunscreen, protecting the skin from harmful, cancer-causing UV rays.

Following a request for assessment in 2020 by the EU, the European Food Safety Authority (EFSA) assessed E171, particularly for its genotoxicity. In 2022, the agency deemed the food additive no longer safe for use.
