In addition to its superior whiteness, TiO2 also offers excellent UV protection. It can absorb and reflect harmful UV rays, protecting materials from degradation and color change. This property is particularly important in outdoor applications, where exposure to sunlight is prolonged.
Some websites maintain titanium dioxide is inferior to zinc oxide, another mineral sunscreen ingredient whose core characteristics are similar to those of titanium dioxide. The reality is that titanium dioxide is a great broad-spectrum SPF ingredient and is widely used in all manner of sun-protection products. What gets confusing for some consumers is trying to decipher research that ranks sunscreen ingredients by a UV spectrum graph. By most standards, broad-spectrum coverage for sunscreen ingredients is defined as one that surpasses 360 nanometers (abbreviated as “nm” - how the sun’s rays are measured). Titanium dioxide exceeds this range of protection, but depending on whose research you read, it either performs as well as or slightly below zinc oxide.
In terms of production, China is the largest producer of both calcium carbonate and titanium dioxide in the world. The country has abundant reserves of both minerals and a well-developed mining and processing industry

china calcium carbonate vs titanium dioxide. China's calcium carbonate production is concentrated in regions such as Guangdong, Guangxi, and Jiangsu, while titanium dioxide production is centered in provinces such as Shandong, Henan, and Sichuan.
One of the key advantages of TiO2 R605 lies in its multi-purpose nature

China's O2Ti, a leading provider of industrial automation solutions, has been making significant strides in the industry. With its innovative products and services, O2Ti is setting new standards for efficiency, quality, and safety in manufacturing processes.
The preferred solution is: in the leaching step, each cubic meter of ammonia-ammonium sulfate solution is added 0. 05kg~0. 1kg of sodium dodecylbenzenesulfonate, sodium dodecylbenzenesulfonate reduces the surface energy of the solution .
In a 2017 study published in Scientific Reports, researchers exposed rats to human-relevant levels of E171 to examine the effects of intestinal inflammation and carcinogenesis. They saw that “a 100-day E171 treatment promoted colon microinflammation and initiated preneoplastic lesions while also fostering the growth of aberrant crypt foci in a chemically induced carcinogenesis model.” They continued: “Stimulation of immune cells isolated from Peyer’s Patches [which are clusters of lymphoid follicles found in the intestine] showed a decrease in Thelper (Th)-1 IFN-γ secretion, while splenic Th1/Th17 inflammatory responses sharply increased,” researchers wrote. “A 100-day titanium dioxide treatment promoted colon microinflammation and initiated preneoplastic lesions.” The scientists concluded: “These data should be considered for risk assessments of the susceptibility to Th17-driven autoimmune diseases and to colorectal cancer in humans exposed to TiO2 from dietary sources.”
Wholesale pigment suppliers are at the heart of distributing this miraculous material, ensuring a steady flow of titanium dioxide to meet global demands. They handle the complex task of matching the specific requirements of different sectors, whether it’s the precise particle size for optimal gloss in cosmetics or the high purity levels needed for certain food grade applications.
On the other hand, titanium dioxide is primarily used as a white pigment in products such as paints, plastics, and cosmetics. It is known for its high opacity, brightness, and whiteness, making it an ideal choice for applications where a bright white color is desired. Titanium dioxide is also used as a UV filter in sunscreen and as a thickening agent in food products.
Le lithopone a été découvert dans les années 1870 par DuPont. Il a été produit par la Krebs Pigments and Chemical Company, entre autres1. Il se faisait en différents grades, en fonction de la teneur en sulfure de zinc. Les qualités « bronze » et « or » contenaient 40 à 50 % de sulfure de zinc, ce qui les rendaient particulièrement couvrantes2. Bien que ce pigment ait atteint son pic de popularité autour de 1920, il s'en produisait encore annuellement plus de 220 000 tonnes en 1990. Il est principalement utilisé dans les peintures, les pâtes et les plastiques3.
Titanium dioxide has similar uses in non-food products. It is used in sunscreen as effective protection against UVA/UVB rays from the sun, which creates a physical barrier between the sun’s rays and the skin. It’s also used to whiten paint, paper, plastic, ink, rubber, and cosmetics.
At the same time, the company took the lead in building a product application testing system in the industry, and formed a relatively complete product application testing system. Among them, the hue of blue-phase R838 titanium dioxide reaches the world-class level. The gloss of R838 titanium dioxide, a silicon-aluminum coated product, has surpassed other domestic silicon-aluminum coated products, and reached or even exceeded some domestic zirconium-aluminum products. Titanium dioxide for color masterbatch is recognized by customers for its high whiteness, high coverage and other indicators, the product market share has been greatly increased, and it enjoys high brand awareness and reputation at home and abroad.
