One of lithopone's outstanding characteristics is its exceptional whiteness. The pigment has a brilliant white color that brings vibrancy and brightness to any application. Whether you are producing paints, coatings, plastics, rubber or printing inks, lithopone will ensure that your end product stands out with its unrivaled pure white shade.
Rio Tinto is a global mining company with operations in Australia, Canada, and Mongolia. The company's rutile production is primarily used for the manufacture of titanium metal, which is used in aerospace, automotive, and medical applications. Rio Tinto is also a major supplier of iron ore, aluminum, and copper, which are essential materials for various industries. Barium sulfate, also known as barite, is a mineral commonly used in various industries such as oil and gas, pharmaceuticals, paint, and plastics. It has a wide range of applications due to its high density and chemical inertness. Therefore, finding reliable suppliers for barium sulfate is crucial for businesses that rely on this versatile mineral. China, as the world's leading producer of titanium dioxide (TiO2), plays a significant role in the global chemical industry. Titanium dioxide, a widely used pigment due to its exceptional whitening and UV-blocking properties, is found in numerous products, from paints and plastics to cosmetics and food additives. However, its production and presence in water bodies have raised environmental concerns. Anatase Titanium Dioxide, a form of titanium dioxide (TiO2), is a highly valued substance due to its exceptional optical properties, high refractive index, and strong UV resistance. It is widely employed as a food additive, approved by international regulatory bodies for its safety and efficacy. This article delves into the significance of anatase TiO2 in the food industry and introduces some prominent food grade anatase titanium dioxide suppliers.Volatile elements 105℃

The Chinese TiO2 industry, with its robust supply chain and advanced manufacturing processes, has been able to produce R996 at a large scale, ensuring consistent quality and competitive pricing. The country's vast mineral resources, particularly ilmenite and rutile, serve as the primary source of titanium, providing a strong foundation for the production of R996.Still many experts say the body of research does not support the current health concerns being expressed about titanium dioxide.
“Unlike some other chemicals used in food, titanium dioxide has no nutritive, preservative, or food safety function—its use is purely cosmetic,” said CSPI principal scientist for additives and supplements, Thomas Galligan. “The prospect of titanium dioxide nanoparticles damaging DNA is concerning enough for us to recommend consumers avoid foods that have it.”
In general, nanoparticles have been shown to accumulate in the body, particularly in organs in the gastrointestinal tract, along with the liver, spleen, and capillaries of the lungs.
In the plastic industry, titanium dioxide serves as a crucial ingredient in creating vibrant colors and improving UV resistance. By incorporating TiO2 into their products, manufacturers can produce durable plastics that withstand exposure to sunlight without fading or degrading. This makes titanium dioxide an indispensable component in the production of outdoor furniture, automotive parts, and other items that require weather resistance.In a 2021, Chinese researchers examined the impact of E171 on lipid digestion and vitamin D3 bioaccessibility in a simulated human gastrointestinal tract model. They examined Vitamin D’s bioaccessibility, or the amount it was released in the gastrointestinal tract, becoming available for absorption, and found it “significantly decreased from 80% to 74%” with the addition of E171. In the experiment, E171 decreased lipid digestion dose-dependently. Researchers wrote: “The findings of this study enhance our understanding toward the potential impact of E171 on the nutritional attributes of foods for human digestion health.” The study was published in the Journal of Agricultural and Food Chemistry,
TiO2 has been well accepted in the food industry and can be found as the E171 additive in various food products, mainly for whitening and texture. It is present in some cottage and Mozzarella cheeses, horseradish cream and sauces, lemon curd, and in low-fat products such as skimmed milk and ice-cream. Even if the product is labelled as containing E171, no information is usually given about the quantity, particle size and particle structure. FDA claims that TiO2 may be safely used as a colour additive for colouring foods in quantities up to 1 % by weight of the food. Interestingly, TiO2 is frequently declared as a “natural colouring agent” and is therefore well accepted by consumers.
Titanium dioxide (TiO2) is commonly applied to enhance the white colour and brightness of food products. TiO2 is also used as white pigment in other products such as toothpaste. A small fraction of the pigment is known to be present as nanoparticles (NPs). Recent studies with TiO2 NPs indicate that these particles can have toxic effects. In this paper, we aimed to estimate the oral intake of TiO2 and its NPs from food, food supplements and toothpaste in the Dutch population aged 2 to over 70 years by combining data on food consumption and supplement intake with concentrations of Ti and TiO2 NPs in food products and supplements. For children aged 2-6 years, additional intake via ingestion of toothpaste was estimated. The mean long-term intake to TiO2 ranges from 0.06 mg/kg bw/day in elderly (70+), 0.17 mg/kg bw/day for 7-69-year-old people, to 0.67 mg/kg bw/day in children (2-6 year old). The estimated mean intake of TiO2 NPs ranges from 0.19 μg/kg bw/day in elderly, 0.55 μg/kg bw/day for 7-69-year-old people, to 2.16 μg/kg bw/day in young children. Ninety-fifth percentile (P95) values are 0.74, 1.61 and 4.16 μg/kg bw/day, respectively. The products contributing most to the TiO2 intake are toothpaste (in young children only), candy, coffee creamer, fine bakery wares and sauces. In a separate publication, the results are used to evaluate whether the presence of TiO2 NPs in these products can pose a human health risk.
Titanium dioxide is a common pigment, and zinc oxide and magnesium oxide are common fillers in rubber base adhesives.
Overall, the Food Directorate's comprehensive review of the available science of TiO2 as a food additive showed:
Prof Matthew Wright, both a member of the FAF Panel and chair of EFSA’s working group on E 171, said: “Although the evidence for general toxic effects was not conclusive, on the basis of the new data and strengthened methods we could not rule out a concern for genotoxicity and consequently we could not establish a safe level for daily intake of the food additive.”
