A few non-dietary studies have reported adverse effects in the gastrointestinal tract of laboratory animals given food-grade TiO2. However, these same effects were not seen when the same or higher doses of food-grade TiO2 were administered in the animals' diet. Dietary studies best reflect how humans are exposed to TiO2 from food. Thus, the Food Directorate placed the most emphasis on the results of these studies in the state of the science report.
One of the primary uses of titanium dioxide is in the production of paints and coatings. It imparts a brilliant white color to these products, making them ideal for use on walls, ceilings, and other surfaces. The chemical properties of titanium dioxide also make it resistant to UV light and weathering, ensuring that painted surfaces remain vibrant and long-lasting.CSPI says it might reconsider its rating if specifications for food-grade titanium dioxide in the U.S. are updated to ensure nanoparticles are minimized, and new studies are conducted to assess its capacity to cause cancer or other health problems.
One of the most remarkable aspects of titanium dioxide is its versatility. It is commonly used as a pigment in paints, coatings, and plastics due to its excellent whiteness, brightness, and opacity. In these applications, titanium dioxide helps to create vibrant and long-lasting colors while also providing durability and resistance to weathering.Rebecca Capua is an assistant conservator in the Paper Conservation Department at the Metropolitan Museum of Art since 2009.

The North American region suffered from the excess influx of material in the market, especially from the Asian countries, in the first half of the third quarter. The quarter, however, showed signs of significant improvement with a rise in the number of offtakes. Further, the lack of labor in the US challenged the rates of production of titanium dioxide and resulted in the depletion in the level of existing inventories, pushing the titanium dioxide price graph in an upward direction.
After classification, the lithopone powder is packaged in airtight containers to prevent exposure to moisture and other contaminantsFor research published in 2022 study in the journal Food and Chemical Toxicology, scientists examined “the genotoxicity and the intracellular reactive oxygen species induction by physiologically relevant concentrations of three different TiO2 nanomaterials in Caco-2 and HT29-MTX-E12 intestinal cells, while considering the potential influence of the digestion process in the NMs’ physiochemical characteristics.” They found a “DNA-damaging effect dependent on the nanomaterial,” along with the micronucleus assay suggesting “effects on chromosomal integrity, an indicator of cancer risk, in the HT29-MTX-E12 cells, for all the tested TiO2 nanomaterials.” Researchers concluded that the results showcase “evidence of concern” regarding titanium dioxide used as a food additive.
When combined, mica and titanium dioxide in shampoo can create a synergistic effect, enhancing each other's benefits
Prof Maged Younes, Chair of EFSA’s expert Panel on Food Additives and Flavourings (FAF), said: “Taking into account all available scientific studies and data, the Panel concluded that titanium dioxide can no longer be considered safe as a food additive . A critical element in reaching this conclusion is that we could not exclude genotoxicity concerns after consumption of titanium dioxide particles. After oral ingestion, the absorption of titanium dioxide particles is low, however they can accumulate in the body”.
The report also provides detailed information related to the lithopone manufacturing process flow and various unit operations involved in a manufacturing plant. Furthermore, information related to mass balance and raw material requirements has also been provided in the report with a list of necessary quality assurance criteria and technical tests.

The concern from animal studies is that high amounts of titanium dioxide have increased inflammation and colon tumor formation, said Dr. Johnson-Arbor. A 2021 review, meanwhile, suggested that using titanium dioxide as a food additive weakens the gut lining and worsens the progression of inflammatory bowel disease.
The efficiency and environmental impact of these factories are constantly under scrutiny. Modern facilities have adopted cleaner technologies to reduce their ecological footprint. Waste management systems ensure that byproducts are recycled or disposed of safely, minimizing pollution. Moreover, energy consumption is optimized through innovative procedures and equipment, aligning with sustainability goals Moreover, energy consumption is optimized through innovative procedures and equipment, aligning with sustainability goalsIn the application of lithopone in ink industry, lithopone has fine particles, loose structure, good fineness and good paint adhesion, so it can be well combined with other colors in the composition of ink.
Recent analyses of food-grade TiO2 samples have found that a significant portion of particles may be within the nanoscale. These particles (also known as nanoparticles) range in size from 1 to 100 nm, where 1 nm equals 1 billionth of a metre (the width of a typical human hair is 80,000 to 100,000 nm).
In order to contribute with experimental evidence that could help to achieve a better understanding of the field for future regulation, in the present work, the biocompatibility of commercial P25TiO2NPs (one type of TiO2NPs used in sunscreen formulations) and two novel functionalized P25TiO2NPs were evaluated under solar simulated irradiation. White light, generated by red, blue, and yellow LEDs, together with UV ones, was chosen to simulate the solar spectra. Functionalization of TiO2NPs was made with antioxidant vitamins in order to prevent the expected photo-initiated ROS production when nanoparticles are exposed to the simulated solar spectra. Vitamin B2 (riboflavin) and vitamin C were chosen to carry out the functionalization because they are water-soluble, low-cost, and are a constitutive part of biological processes. In addition, it is known that both have the potential to prevent macromolecular oxidation by ROS [23], [24], [25], [26].
Lithopone, a white pigment composed of a mixture of barium sulfate and zinc sulfide, is commonly used in the leather industry as a coloring agent. Leather suppliers around the world rely on lithopone to achieve the desired color and finish on their products.
In 2021, the European Food Safety Authority concluded that titanium dioxide is no longer safe in foods due to the same concerns over nanoparticles. As a result, titanium dioxide is now banned as a food additive in the EU. Although studies have shown that the absorption of ingested titanium dioxide is low, evidence suggests that titanium dioxide nanoparticles can accumulate in the body over time. Health Canada deemed it safe in 2022 but noted concerns. Unlike their European counterparts, Canadian officials did not consider studies performed with titanium dioxide nanoparticles alone.
There are many ways we’re exposed to titanium dioxide in our everyday life. Below are the most common ways we encounter titanium dioxide.
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.Titanium dioxide, or TiO2, sometimes referred to as E171, is an inorganic, solid substance used in a wide range of consumer goods including cosmetics, paint, plastic and food, according to the American Chemistry Council.
In the realm of product development, TIO2 pigment manufacturers are also focusing on creating specialized grades for niche applications. For instance, antimicrobial TIO2 pigments can be used in healthcare settings to prevent infection, while photocatalytic TIO2 can help in air purification systems by breaking down harmful pollutants. The production process of titanium dioxide powder mainly includes ore selection, acid decomposition, hydrolysis, washing, drying, calcination, and crushing. During this process, strict quality control is required to ensure that the final product meets the relevant standards. Moreover, environmental protection measures must be taken during the production process to minimize the impact on the environment.
