- The chemical industry is vast and diverse, encompassing everything from pharmaceuticals and cosmetics to paints and industrial chemicals. These products are manufactured by companies large and small, each contributing to the complex supply chain that keeps our world running smoothly.
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”.

- Firstly, it is important to understand that TiO2 can be classified into two main types rutile and anatase. Rutile TiO2 is known for its excellent UV resistance, making it ideal for use in sunscreens, paints, and coatings. On the other hand, anatase TiO2 has a higher surface area and is often used in photocatalytic applications, such as self-cleaning coatings and air purification systems.
- 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.
- Overall, universal type products like R996 are essential components in the production of high-quality paints. Their unique properties, including bright white color, high opacity, UV resistance, and versatility, make them ideal choices for a wide range of applications. Whether used in interior or exterior paints, industrial coatings, or automotive finishes, R996 and other titanium dioxide pigments play a critical role in creating paints that are durable, attractive, and long-lasting.

Based on this opinion, the European Commission and the Member States agreed to remove all uses of titanium dioxide as an additive in food. In January 2022, a Regulation withdrawing the authorisation to use titanium dioxide as a food additive in food products was adopted i.e. Commission Regulation (EU) 2022/63.
- In the competitive world of manufacturing, finding a reliable titanium white oem supplier is paramount to ensuring the success of your products. Titanium dioxide, commonly known as titanium white, is a crucial pigment used in various industries due to its excellent whiteness, opacity, and chemical stability. Whether you are a manufacturer of coatings, plastics, or paper, choosing the right titanium white oem supplier can significantly impact the quality and performance of your end products.
The trend in the production of NPs is likely to lead to increasing amounts of nano-powders in the air, water and soil, which will consequently affect living organisms. Labielle et al. demonstrated that 25 % of Al(OH)3-coated TiO2 particles from sunscreens are dispersed as a stable colloid and become available to microorganisms and filter-feeders, while the remaining 75 % are probably incorporated into geogenic sediments, where they could become available to benthic fauna. Solar UV iradiation may penetrate as far as 20 m in the water column and therefore photo-activate the dispersed particles, which may have an adverse effect on various aquatic organisms.

When E171 is part of a food product, it passes through the digestive system without causing harm because E171 combines with the other ingredients.
In their role as risk managers, the European Commission and Member States will now reflect on EFSA’s scientific advice and decide upon any appropriate regulatory measures or advice for consumers.
4. Technical Support and Service A collaborative relationship with suppliers can greatly enhance the user experience. Suppliers that provide technical support and advice about potential applications or formulations can add significant value to their customers.
- There are several manufacturers of barium sulfate around the world, each offering different prices for their products. Some of the leading manufacturers of barium sulfate include Solvay, Basf, and Huntsman. These companies are known for their high-quality products and competitive prices.
- Titanium dioxide, also known as TiO2, is a widely used white pigment in various industries due to its excellent light-scattering properties and high refractive index. The pH of titanium dioxide plays a crucial role in its performance and applications.
- The journey of TIO2 begins with mining raw materials, primarily ilmenite, rutile, and anatase minerals, which are then processed through various methods including the chloride process or the sulfate process. The chosen procedure significantly impacts the final characteristics of the TIO2 pigment, such as its particle size, distribution, and crystalline structure, which in turn affect its optical properties.
Throughout the fourth quarter of 2021, the European market had consistent optimistic sentiment. Despite the overwhelming inventories at lower levels during the fourth quarter of 2021, the demand prognosis in the domestic market revealed varied opinions. Imports from the Asia Pacific region, on the other hand, remained disruptive due to limited accessibility of vessel freights and a decrease in the PMI index for titanium dioxide in China despite the application of severe environmental protection measures.

3. The calcined product obtained by the ordinary zinc bismuth method is slurried into a slurry, which is sequentially treated with sodium silicate, aluminum sulfate or sodium aluminate and a surfactant, and then filtered, washed, dried and pulverized.
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,
However, the market could not sustain these high prices and strived for equilibrium, causing the prices to fall. Further, after the complete removal of restrictions, the factories churned out products at a much faster pace than the market offtakes. Hence, the manufacturers reduced their quotations to maintain positive product movement in the market. The spot prices of titanium dioxide averaged around 2264 USD/MT in June’23 in the Chinese market.
Lyophilized vitamins@P25TiO2NPs were obtained through the described methods with excellent reproducibility and yield: over 99% of initial P25TiO2NPs were functionalized.
