Although barium sulfate is almost completely inert, zinc sulfide degrades upon exposure to UV light, leading to darkening of the pigment. The severity of this UV reaction is dependent on a combination of two factors; how much zinc sulfide makes up the pigments formulation, and its total accumulated UV exposure. Depending on these factors the pigment itself can vary in shade over time, ranging from pure white all the way to grey or even black. To suppress this effect, a dopant may be used, such as a small amount of cobalt salts, which would be added to the formulation. This process creates cobalt-doped zinc sulfide. The cobalt salts help to stabilize zinc sulfide so it will not have as severe a reaction to UV exposure.
④ Ink industry: titanium dioxide is also an indispensable white pigment in advanced ink. The ink containing titanium dioxide is durable and does not change color, has good surface wettability and is easy to disperse. The titanium dioxide used in the ink industry includes rutile and anatase.
Due to its low binder requirement, lithopone provides paints with good flow and application properties. In the plastic processing industry, it is added to plastics to increase the plastic product’s UV tolerance, thus increasing its outdoor life. In the leather industry, it is one of the sulfide-based white pigments. It is also used in the production of linoleum floorings.
The FDA's Code of Federal Regulations allows for the legal, regulated use of titanium dioxide in food products, under some restrictions.
Titanium dioxide, often abbreviated as TiO2, is renowned for its high refractive index and exceptional ability to withstand sunlight without fading. These properties make it indispensable in products ranging from paint and plastics to paper and food colorants. The demand for this versatile oxide is ever-growing, pushing factories to optimize their production processes and balance the scales of supply and demand effectively.The Lithopone market is segmented into application, and region. The major applications studied in the global Lithopone market report include paints & coatings, plastics, printing inks, paper & pulps, rubber, leather, linoleum, and others. Region-wise, the market is studied across North America, Europe, Asia-Pacific, and LAMEA.
Moreover, TIO2's contribution extends beyond color enhancement. It introduces a corrosion-resistant barrier within paints, safeguarding underlying surfaces from the detrimental effects of moisture, chemicals, and UV radiation. This protective quality is of paramount importance for exterior applications, where exposure to environmental elements is inevitable. In architectural paints, for instance, the inclusion of TIO2 not only beautifies structures but also prolongs their lifespan by combating weathering In architectural paints, for instance, the inclusion of TIO2 not only beautifies structures but also prolongs their lifespan by combating weatheringWhen 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.
In addition to cost savings, wholesalers also provide paint companies with access to a wide range of titanium dioxide grades and formulations. Different grades of titanium dioxide are used in paints depending on the desired opacity, brightness, and durability of the final product. Wholesalers can help paint companies select the right grade of titanium dioxide for their specific application, ensuring optimal performance and qualityStill many experts say the body of research does not support the current health concerns being expressed about titanium dioxide.
The demand for titanium dioxide continues to grow as industries such as construction, automotive, and consumer goods expand. As a result, importers play a vital role in ensuring a steady supply of this critical material. They must navigate complex international trade regulations, tariffs, and logistics to maintain a consistent flow of titanium dioxide into their markets. 3. Price and AvailabilityThe California plaintiff is apparently not the only one concerned about titanium dioxide. The European Union recently banned its use citing concerns about serious health consequences.

Furthermore, the concept of green chemistry is gaining traction in the Chinese TiO2 industry. Companies are exploring eco-friendly production methods, such as using chloride-route technology that generates less wastewater and has a lower environmental impact compared to the traditional sulfate route.② Plastics: At present, it is the second largest user of titanium dioxide pigments, accounting for about 20% of the total demand for titanium dioxide. The amount of titanium dioxide used in plastic products will vary with the use requirements, generally between 0.5% and 5%. According to data from the National Bureau of Statistics, the production of plastic products in China increased from 57.81 million tons in 2012 to 81.84 million tons in 2019, with a compound annual growth rate of 5.1%. The amount of titanium dioxide increases accordingly.
In addition to its pharmaceutical applications, barium sulphate is extensively utilized in the production of paints and coatings, where a bright white pigment is essential. The opacity and brightness provided by barium sulphate make it a popular choice in formulations for white and colored paints. Its non-toxic nature and excellent stability enhance its appeal in these products.
The US and Canada, however, approve the use of titanium dioxide as a food additive. Canada's recent review of titanium dioxide reconfirmed its safety and pointed out that many of the toxicity studies the EU reviewed were not relevant to the safety of titanium dioxide as a food ingredient, and that the ban is based on an abundance of caution and uncertainty.
