The Scientific Committee on Consumer Safety (SCCS) warns against sprayable products and powders that may expose users’ lungs to titanium dioxide through inhalation (10).
The overseas demand for Chinese TiO2 rose up by about 17% in 2016, which enabled an export increase of the manufacturers in China. As a fact, Chinese TiO2 is highly demanded in overseas markets, due to the comparable small price of the suppliers. The export of TiO2 is responsible for about one-third of the total output in China.
As a food additive, titanium dioxide and its nanoparticles in particular have been associated with DNA damage and cell mutations, which in turn, have potential to cause cancer. When used as a food coloring, it is known as E171.
- One of the most promising applications of TiO2 in medicine is its use as a drug delivery system. Due to its biocompatibility and ability to encapsulate drugs, TiO2 nanoparticles can be engineered to release medication slowly over time, improving treatment efficacy and reducing side effects. This technology has been explored extensively in China for targeted drug delivery in treating diseases like cancer and diabetes.
- Titanium dioxide, commonly known as TiO2, is a naturally occurring oxide of titanium. Among its two primary crystal forms, rutile TiO2 is particularly valued for its high refractive index and exceptional hiding power, making it an essential component in the production of emulsion latex paints. The unique properties of rutile titanium dioxide enhance the quality and performance of latex paints, establishing its manufacturer's reputation for producing top-tier products.

- The wholesale titanium dioxide (TiO2) market is a key sector in the global chemical industry, with a wide range of applications in various end-use industries such as paints and coatings, plastics, paper, and textiles. Titanium dioxide is a white pigment that is used to impart opacity, brightness, and durability to products.
Lithopone
The use of titanium dioxide (TiO2) in factory settings is widespread, with this versatile compound playing a crucial role in various industrial processes. TiO2 is a naturally occurring mineral that is widely used as a white pigment in paints, coatings, plastics, paper, and other products. Its ability to effectively scatter light makes it an ideal choice for creating bright, durable, and long-lasting finishes.
One of the key factors that affect the precipitation of titanium dioxide is the precipitation percentage, which is the percentage of titanium sulfate that is converted to titanium hydroxide during the reaction
. The precipitation percentage is influenced by a variety of factors, including the concentration of titanium sulfate, the pH of the reaction mixture, the temperature, and the reaction time.

It is composed of a mixture of barium sulfate and zinc sulfide. These insoluble compounds blend well with organic compounds and confer opacity. It was made popular by the cheap production costs, greater coverage. Related white pigments include titanium dioxide, zinc oxide (zinc white), zinc sulfide, and white lead.
- Several leading suppliers have established themselves in the global market for food-grade anatase titanium dioxide. One such supplier is Evonik Industries, a German multinational chemical company. They offer high-quality TiO2 products under the brand name Tixosil, specifically designed for food applications. Their products adhere to strict quality standards and comply with global regulations.

- Lithopone, a versatile white pigment, has been a staple in the world of colorants for decades due to its excellent opacity, stability, and cost-effectiveness. It is a mixture of zinc sulfide and barium sulfate, providing a superior white shade in various applications, including paints, plastics, printing inks, and coatings. This article delves into the lithopone pigment price list and highlights key suppliers in the market.

The high brightness of calcium carbonate can also enhance the reflective properties of the paint, making it ideal for use in applications where a bright, clean finish is desired. - In addition to its uses in traditional industries, titanium dioxide is also finding new applications in emerging fields such as solar energy and water treatment. In solar cells, titanium dioxide is used as a photocatalyst to convert sunlight into electricity. In water treatment, it is used to remove impurities and disinfect water, making it suitable for drinking and industrial use.

- 3. In the production of a composite pigment the steps comprising slowly adding titanium oxide to a solution of barium sulphide while rapidly agitating the solution, mixing the resultant mass with a solution of zinc sulphate and separating'the composite precipitate.
Titanium dioxide has a number of unique characteristics that make it ideally suited to many different applications.
“Unlike some other chemicals used in food, titanium dioxide has no nutritive, preservative, or food safety function—its use is purely cosmetic,” said CSPI principal scientist for additives and supplements, Thomas Galligan. “The prospect of titanium dioxide nanoparticles damaging DNA is concerning enough for us to recommend consumers avoid foods that have it.”

JECFA previously assessed titanium dioxide at its 13th meeting, at which time the expert committee assigned a “not specified” ADI for the additive due to an absence of significant absorption and a lack of toxicological effects in the available experimental animal and human studies. Since its original evaluation by JECFA, titanium dioxide has become a public point of contention, with its ban being introduced (and then subsequently withdrawn) in California legislation in 2023, a legal battle playing out in the EU over the additive’s ban and classification as a carcinogen in 2022, and the European Food Safety Authority (EFSA) calling titanium dioxide unsafe. However, supporters of titanium dioxide say that claims about its dangers are founded in unreliable studies, and some recent research has supported its safety as a food additive.

Packaging containing this additive has been shown to decrease ethylene production in fruit, thus delaying the ripening process and prolonging shelf life (4Trusted Source).
