  • 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”. 

  • 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.

  • In addition to these factors, global economic conditions and trade policies can also affect the anatase price. Fluctuations in currency exchange rates and changes in import/export duties can make anatase more or less expensive for different countries. For example, if a country imposes high tariffs on imported anatase, it may encourage local production but could also increase the cost for consumers within that country.
  • In recent years, the titanium dioxide industry has experienced significant price fluctuations due to changes in supply and demand dynamics. The COVID-19 pandemic has further exacerbated these challenges, leading to disruptions in the supply chain and increased production costs. As a result, suppliers have had to adjust their pricing strategies to remain competitive while maintaining profitability.

  • Still, you may wonder whether it’s safe for consumption.

  • The global demand for lithopone has been steadily increasing in recent years, driven by the growth of the construction, automotive, and electronics industries

  • One of the most significant uses of titanium dioxide is in the production of paints and coatings. It acts as a pigment that provides brightness, opacity, and durability to the final product. The high refractive index of titanium dioxide allows it to scatter light effectively, making it ideal for creating opaque finishes. Moreover, its chemical stability ensures that the color remains consistent over time, even when exposed to harsh environmental conditions.
  • Availability of alternative inorganic white pigments, mainly Titanium Dioxide (TiO2) pigments

  • Earlier this year, a bill was introduced in the California legislature to ban the manufacture, sale and distribution of foods in the state containing titanium dioxide, along with four other harmful food chemicals. 

  • On absorption of UV light, photo-generated titanium dioxide particles create singlet oxygen, superoxide anions (O2-) and hydroxyl radicals (OH-) that are potent free radicals (1,2). Irradiated particles of titanium dioxide can induce oxidative damage to DNA (2) which can lead to the development of mutant cells and skin cancers (3,4,5,6) and lipid peroxidation of essential functions on the cell membrane (7).

  • Incorporating rutile TiO2 into latex paints requires meticulous attention to dispersion techniquestitanium dioxide rutile tio2 emulsion latex paints manufacturer. Manufacturers utilize high-speed mixing equipment to evenly distribute the pigment particles throughout the emulsion, preventing agglomeration and ensuring consistent product quality. The concentration of rutile TiO2 used depends on the desired level of hiding power and the specific end-use requirements of the paint.
  • The production of precipitated titanium dioxide involves a meticulous procedure, where titanium salts are reacted with alkalis or acids to create a precipitate. The resulting product is then washed, dried, and calcined to achieve the desired particle size, shape, and surface area. This process allows for customization, making it a popular choice among manufacturers.
  • The versatility of rutile TiO2 extends beyond its physical and chemical properties. It can be modified through various surface treatments, such as doping with other elements or compounds, to enhance its performance in specific applications. For example, doping with nitrogen can improve the photocatalytic activity of rutile TiO2, making it more effective at degrading organic pollutants.
  • The global market for rutile titanium dioxide is competitive, with leading manufacturers continuously striving to improve their production processes and product quality
  • In the sulfate process, the titanium-rich ore is reacted with sulfuric acid, giving TiOSO4. Pure TiO2 is obtained from TiOSO4 in several steps, going via TiO(OH)2. Depending on the chemistry and route chosen, either rutile or anatase titanium dioxide is made.
  • Wholesalers of titanium dioxide for paint are responsible for sourcing the raw material from manufacturers and distributing it to paint companies in bulk quantities. They often work closely with manufacturers to ensure a steady supply of titanium dioxide at competitive prices.

  • Whiteness is a critical factor in the performance of pigments, and TiO2 excels in this area. Its high refractive index allows it to scatter light more effectively, resulting in a brighter and more luminous color. This makes TiO2 particularly suitable for applications where maximum whiteness is required, such as in paints, plastics, and paper.

  • Oil absorption, g/ 100g

  • Duan et al. administered 125 mg/kg BW or 250 mg/kg BW of anatase TiO2 (5 nm) intragastrically to mice continuously for 30 days. The exposed mice lost body weight, whereas the relative liver, kidney, spleen and thymus weights increased. Particles seriously affected the haemostasis of the blood and the immune system. The decrease in the immune response could be the result of damage to the spleen, which is the largest immune organ in animals and plays an important role in the immune response. Powel et al. demonstrated that TiO2 NPs may trigger immune reactions of the intestine after oral intake. They showed that TiO2 NPs conjugated with bacterial lipopolysaccharide, but not TiO2 NPs or lipopolysaccharide alone, trigger the immune response in human peripheral blood mononuclear cells and in isolated intestinal tissue. This indicates that TiO2 NPs may be important mediators in overcoming normal gut-cell hyporesponsiveness to endogenous luminal molecules, which may be particularly relevant to patients with inflammatory bowel disease, which is characterized by an abnormal intestinal permeability.

  • Another key factor contributing to the growth of the market is the rising awareness among consumers regarding environmental sustainability. Titanium dioxide is frequently used as a pigments in eco-friendly construction materials and coatings, which are perceived as more environmentally friendly than traditional options. As consumers become increasingly conscious about their impact on the environment, they are actively seeking out these products, leading to increased demand for sustainable titanium dioxide solutions As consumers become increasingly conscious about their impact on the environment, they are actively seeking out these products, leading to increased demand for sustainable titanium dioxide solutions As consumers become increasingly conscious about their impact on the environment, they are actively seeking out these products, leading to increased demand for sustainable titanium dioxide solutions As consumers become increasingly conscious about their impact on the environment, they are actively seeking out these products, leading to increased demand for sustainable titanium dioxide solutionswholesale titanium dioxide market report.
