So, what does it all mean for you, the consumer? Should you stop eating Skittles or begin checking foods for the presence of titanium dioxide? Here's a closer look.
- Avoid ultra-processed foods whenever possible. Many contain concerning ingredients in addition to titanium dioxide.
- The Chinese titanium dioxide industry has experienced exponential growth over the past decades, accounting for a substantial portion of the global output. This boom is driven by the country's vast resources of ilmenite, a primary source of titanium, and the demand from various sectors. However, the manufacturing process of TiO2 involves large amounts of water, which can lead to potential water pollution if not managed properly.
Health Canada's Food Directorate recently completed a “state of the science” report on titanium dioxide (TiO2) as a food additive. Food-grade TiO2 is a white powder made up of small particles that has been permitted in Canada and internationally for many years as a food additive to whiten or brighten foods. Food-grade TiO2 has long been considered safe in Canada and in other countries when eaten as part of the diet.
The application of lithopone in building materials industry can not only be used as water-soluble coatings for interior and exterior walls of buildings, but also as fillers for wallpaper, floor paint, dining table and other plastic all ceramic veneers.
- One of the key considerations when using titanium dioxide in food products is its particle size. The FDA has set limits on the particle size of titanium dioxide that can be used in food products, as smaller particles may pose a greater health risk. It is important to ensure that the titanium dioxide purchased meets these particle size standards to ensure the safety of the product.
- One of the key applications of TiO2 in China is in masterbatch and plastic production. Masterbatch is a concentrated mixture of pigments or additives that are dispersed in a polymer carrier, which is then used to color plastics. TiO2 is a commonly used pigment in white masterbatches, providing excellent color strength and opacity to plastic products.
Lithopone is a white pigment (PW5) co-precipitated from solutions of zinc and barium salts according to the following reaction:
Genotoxicity Assessment
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).
The trend in the production of NPs is likely to lead to increasing amounts of nano-powders in the air, water and soil, which will consequently affect living organisms. Labielle et al. demonstrated that 25 % of Al(OH)3-coated TiO2 particles from sunscreens are dispersed as a stable colloid and become available to microorganisms and filter-feeders, while the remaining 75 % are probably incorporated into geogenic sediments, where they could become available to benthic fauna. Solar UV iradiation may penetrate as far as 20 m in the water column and therefore photo-activate the dispersed particles, which may have an adverse effect on various aquatic organisms.
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.
- Chinese manufacturers adhere to strict quality control standards, ensuring that their anatase TiO2 meets international specifications. The 99.6% purity level is achieved through sophisticated purification techniques, including leaching, precipitation, and calcination processes. These methods remove impurities such as iron, sulfur, and organic compounds, resulting in a product with exceptional whiteness, brightness, and dispersion properties.
- Moreover, the pigment titanium dioxide factory fosters a culture of continuous learning and improvement. Employee training programs and investments in cutting-edge technology reflect a forward-thinking approach. By staying attuned to the latest developments in materials science and industrial processes, the factory ensures that it remains at the forefront of pigment production.

A 1250 mesh sieve indicates an incredibly fine mesh size, where particles pass through a sieve with approximately 1250 openings per square inch. This level of fineness is crucial for applications requiring minute particle separation, such as in the production of high-quality powders or ultra-refined materials.
- Rutile TiO2, a naturally occurring mineral, is renowned for its exceptional properties. It is highly reflective, which means that when incorporated into wallpaper, it can significantly brighten any room. This makes it an ideal choice for those seeking to create a light and airy atmosphere in their living spaces.
In 1970, Japanese scholars studied the phase diagram of iron oxide microcrystalline formation, which laid a theoretical foundation for the preparation method of iron oxide yellow crystal seed. According to the research results, iron yellow crystal seeds can be formed under acidic or alkaline conditions. Because iron yellow is a crystal structure, in order to crystallize into pigment particles, it must first form crystal nucleus and become crystal seed, and then the crystal nucleus grows into iron yellow. Otherwise, only thin and dim color paste can be obtained, which does not have pigment properties. Acid process can be divided into iron sheet process and drop addition process.
