Titanium is a metal element found naturally in the environment. When it's exposed to oxygen in the air, it forms titanium oxides that are contained in many minerals, sands, soils, and dusts.
- The Chinese government's focus on infrastructure development and urbanization has fueled the demand for TiO2 in construction materials, coatings, and other related sectors. Moreover, the country's thriving automotive and packaging industries have further stimulated the growth of the TiO2 market. The increasing use of TiO2 in solar panels and other high-tech applications has added another dimension to this billion-ton industry.
- Leading suppliers play a pivotal role in this landscape
- Mesh, in the context of sieving, denotes the number of openings in a linear inch of a screen or sieve. 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.
Applications of Lithopone Powder:
Magnesium oxide (MgO). It is used as a curing agent and an acid scavenger in solvent-borne polychloroprene adhesives. It is a white powder with a high melting point. It has a greater ability to reflect visible light more efficiently than titanium dioxide
Titanium dioxide comes in the form of a white powder and is sometimes used in cosmetics to adjust a color to a lighter shade. This is also why it can produce a white cast.


5. Geographical Availability Depending on the location of businesses, suppliers with a good logistical network can ensure timely delivery and availability of stock. Local suppliers may also provide cost advantages compared to international counterparts due to reduced shipping fees.
One of the most widely used food pigments is titanium dioxide, an odorless powder that enhances the white color or opacity of foods and over-the-counter products, including coffee creamers, candies, sunscreen, and toothpaste (1Trusted Source, 2Trusted Source).

Where does titanium dioxide come from?
EFSA’s scientific advice will be used by risk managers (the European Commission, Member States) to inform any decisions they take on possible regulatory actions.
Macromolecular oxidation was detected in proteins by the colorimetric measurement of Advanced Oxidation Protein Products (AOPP) and in lipids by the colorimetric quantification of malondialdehyde (MDA). Standard curves were run with chloramine-T and 1,1,3,3 tetraethoxypropane (TEP) for AOPP and MDA methods, respectively [29], [30], [31]. Values were normalized to initial protein content in samples, measured with Bradford reagent [32]. The standard deviation of at least six measures was calculated and p-value < 0.05 were considered significant.
A 2023 study published in the journal Particle and Fibre Toxicology set out to examine the impact of titanium dioxide nanoparticles in mice “on the course and prognosis of ulcerative colitis,” by creating an ulcerative colitis disease model. Researchers found that the titanium dioxide nanoparticles significantly increased the severity of colitis. They also “decreased the body weight, increased the disease activity index and colonic mucosa damage index scores, shortened the colonic length, increased the inflammatory infiltration in the colon.” Researchers concluded: “Oral intake of TiO2 nanoparticles could affect the course of acute colitis in exacerbating the development of ulcerative colitis, prolonging the ulcerative colitis course and inhibiting ulcerative colitis recovery.”


When E171 isn’t combined with other ingredients and administered in water, some studies suggest that under these artificial conditions, E171 may be processed differently in the body resulting in some biological changes in experimental animals that are poorly understood.
