- However, China's Tio2 pigment industry is not without challenges
china tio2 for pigment. Environmental concerns, stringent regulations, and the need for sustainable production methods are mounting pressures on the sector. The industry is increasingly focusing on improving efficiency and reducing carbon footprints, which could lead to technological innovations and a shift towards eco-friendly production.
- Manufacturers of latex paints recognize the importance of incorporating rutile TiO2 into their formulations. This form of titanium dioxide imparts excellent opacity, which is crucial for achieving uniform coverage and concealing underlying surfaces effectively. The ability to hide imperfections with fewer coats not only saves time but also reduces material costs, contributing to more efficient and economical painting projects.
Genotoxicity refers to the ability of a chemical substance to damage DNA , the genetic material of cells. As genotoxicity may lead to carcinogenic effects, it is essential to assess the potential genotoxic effect of a substance to conclude on its safety.
French researchers studied how and where E171 nanoparticles enter the bloodstream, first studying the route through pigs and then in vitro with human buccal cells, for a 2023 study published in the journal Nanotoxicology. The research showed that the nanoparticles absorbed quickly through the mouth and then into the bloodstream, before damaging DNA and hindering cell regeneration.
Below 10% substitution, 1 kg of TiO2 should be replaced by 1 kg of Lithopone 30%.

- Titanium Dioxide for Plastic Manufacturers An Essential Ingredient
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.
Pure titanium dioxide is a fine, white powder that provides a bright, white pigment. Titanium dioxide has been used for a century in a range of industrial and consumer products, including paints, coatings, adhesives, paper, plastics and rubber, printing inks, coated fabrics and textiles, as well as ceramics, floor coverings, roofing materials, cosmetics, toothpaste, soap, water treatment agents, pharmaceuticals, food colorants, automotive products, sunscreen and catalysts.
- Agriculture grade calcium carbonate is used in agriculture as a soil conditioner to neutralize acidic soils and improve nutrient uptake by plants. It is typically coarser in particle size compared to other grades to ensure better soil penetration and improved effectiveness. Agriculture grade calcium carbonate is also used in animal feed as a source of calcium for livestock.
Recently, Yanagisawa et al. reported that the transdermal exposure (mimicking skin-barrier dysfunction or defect) of NC/Nga mice to TiO2 NPs (15, 50, or 100 nm), in combination with allergen, aggravated atopic dermatitis-like lesions through a T-helper type 2 (Th2) dominant immune response. The study also indicated that TiO2 NPs can play a role in the initiation and/or progression of skin diseases, since histamine was released, even in the absence of allergen.
- The global market for precipitated titanium dioxide is competitive, with suppliers operating on both regional and international scales. Some prominent players include Evonik Industries, Cristal Global, Tronox, and Venator Materials. These companies not only focus on production but also invest heavily in research and development to innovate and improve their products continually.

Lithopone was discovered in the 1870s by DuPont. It was manufactured by Krebs Pigments and Chemical Company and other companies. The material came in different seals, which varied in the content of zinc sulfide. Gold seal and Bronze seals contain 40-50% zinc sulfide, offering more hiding power and strength. Although its popularity peaked around 1920, approximately 223,352 tons were produced in 1990. It is mainly used in paints, putty, and in plastics.
Titanium dioxide, (TiO2), a white, opaque, naturally occurring mineral existing in a number of crystalline forms, the most important of which are rutile and anatase. These naturally occurring oxide forms can be mined and serve as a source for commercial titanium. Titanium dioxide is odourless and absorbent. Its most important function in powder form is as a widely used pigment for lending whiteness and opacity.
- The prices of lithopone are influenced by several factors, including raw material costs, production capacity, supply and demand dynamics, regional economic conditions, and environmental regulations. Zinc and sulfur, the primary components of lithopone, are subject to fluctuations in their global market prices, which directly impacts the cost of lithopone production. Additionally, stricter environmental norms often lead to increased production costs for manufacturers, affecting the final pricing.
Zinc oxide. Zinc oxide is a popular cross-linking agent for rubber and for various resins. It is essential in the formulation of solvent-borne polychloroprene adhesives. Furthermore, zinc oxide is a good UV stabilizer, has biocidal activity and has a relatively high refractive index (2.0) which makes it an efficient white pigment. Some typical properties are: density 5.6 g/cm3; particle size 0.036-3 μm; oil absorption 10–20 g/100 g; specific surface area 10–45 m2/g. Zinc oxide is produced by reaction of the metal in the vapour state with oxygen. Zinc oxide is nonporous and is quite pure. Thus, the high surface area of some grades is due to the small particle size of zinc oxide. Some grades, especially for use in the rubber industry, are surface modified by deposition of 0.2-0.4% of stearic acid, propionic acid, or light oil [47].

R-996:
Scrap zinc or concentrated zinc ores are dissolved in sulfuric acid, the solution is purified and the two solutions are reacted. A heavy mixed precipitate results that is 28 to 30% zinc sulfide and 72 to 70% barium sulfate.
