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.
The effects of TiO2 NPs in plants
- In conclusion, titanium dioxide is an essential ingredient in the production of high-quality paper products, helping to ensure that papers are not only visually appealing but also durable and long-lasting. Its versatility and effectiveness make it a popular choice for paper manufacturers looking to enhance the performance and aesthetics of their products. Whether used in coated papers, specialty papers, or archival papers, titanium dioxide continues to be a key component in the success of the paper industry.
Food safety experts in the European Union (EU) have recently updated their safety assessment of TiO2 as a food additive. In Europe, TiO2 is referred to as E171, in accordance with European labelling requirements for food additives. The EU expert panel took into account toxicity studies of TiO2 nanoparticles, which to this point had not been considered relevant to the safety assessment of TiO2 as a food additive.
- R5566 is a versatile rutile titanium dioxide that finds applications in a wide range of industries, including cosmetics, textiles, and ceramics. Its superior whiteness and brightness make it a preferred choice for achieving impeccable finishes in various products. R5566 also offers good UV resistance, making it suitable for use in outdoor applications where exposure to sunlight is a concern.
Exposure routes are the pathways that allow ingredients to enter our bodies. Primary exposure routes include:
- In addition to offering a wide range of titanium dioxide products, suppliers also provide technical support and expertise to help manufacturers optimize their coating formulations
titanium dioxide for coatings suppliers. They work closely with customers to understand their specific needs and requirements, providing guidance on the selection of titanium dioxide grades and the formulation of coatings to achieve optimal results. By leveraging their expertise in coatings and materials science, suppliers of titanium dioxide contribute to the development of innovative coatings solutions that deliver superior performance and durability. In a study published in the journal Environmental Toxicology and Pharmacology in 2020, researchers examined the effects of food additives titanium dioxide and silica on the intestinal tract by grouping and feeding mice three different food-grade particles — micro-TiO2, nano-TiO2, and nano-SiO2. With all three groups, researchers observed changes in the gut microbiota, particularly mucus-associated bacteria. Furthermore, all three groups experienced inflammatory damage to the intestine, but the nano-TiO2 displayed the most pronounced changes. The researchers wrote: “Our results suggest that the toxic effects on the intestine were due to reduced intestinal mucus barrier function and an increase in metabolite lipopolysaccharides which activated the expression of inflammatory factors downstream. In mice exposed to nano-TiO2, the intestinal PKC/TLR4/NF-κB signaling pathway was activated. These findings will raise awareness of toxicities associated with the use of food-grade TiO2 and SiO2.”
- In conclusion, China's role in the global TiO2 market is significant, particularly in the paints and inks sector. With its abundant resources, advanced manufacturing capabilities, and commitment to quality and sustainability, China will continue to be a major player in the TiO2 industry for years to come. By addressing environmental challenges and maintaining a focus on innovation, China can further strengthen its position as a leading producer and exporter of TiO2 in the global market.

- The rutile market is dominated by a few key manufacturers who supply the majority of the world's rutile. These manufacturers are primarily located in countries with abundant mineral resources, such as Australia, South Africa, and China. Some of the leading rutile manufacturers include Iluka Resources, Tronox Limited, Rio Tinto, and Guangdong Huiyun Titanium Industry Co., Ltd.
- 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.
Those scientists found that sunscreen residue on the roof installers fingertips were being transferred to the colour bond sheets during installation & with titanium dioxide’s photo-sensitivity & the lovely sun’s help, the paint was literally peeling off those roofs.
- At present, the domestic wet zinc smelting mainly adopts the roasting-leaching-electrowinning production process, and the zinc content in the acid leaching residue is generally 8-15%, some up to 20%, and the sulfur mass fraction is 6-12%, of which sulfuric acid The root mass fraction is 15-30%, mainly in the form of 0^0 4 (in this ammoniatic environment, the leaching rate of sulfate leaching in multiple stages can reach 70%). The zinc in the acid leaching residue is mainly in the form of ZnFe 2 0 4 . In order to recover these zinc, the treatment methods are currently available in the fire method and the wet method. The fire method is the rotary kiln evaporation method (Wilz method) and the fumigating furnace evaporation method. . The wet method has hot acid leaching or high temperature pressure leaching. The fire treatment process is long, the equipment maintenance is large, the investment is high, the working environment is poor, and a large amount of coal or metallurgical coking coal is consumed, which has low efficiency and large environmental pollution. Therefore, it is usually leached by hot acid or high-pressure leaching. These methods still have the disadvantages of: 1 consumption of a large amount of acid, low leaching rate, due to the large amount of calcium sulfate, calcium sulphate and other ultrafine particles to isolate the zinc oxide particles, resulting in Electrolytic zinc enterprises are difficult to leach in acid environment, and the second weak acid leaching is not meaningful because the recovery rate is too low. 2 If leached with strong acid, although ZnFe 2 0 4 is destroyed, the leaching rate is improved, but the iron leaching rate is also high (up to 60%). The pressure of iron removal is large, and more reagents are consumed. 3 High temperature and high pressure equipment is corroded. Serious, complicated equipment investment; 4 high operating costs, poor economic returns. 5 The last slag discharged is acid leaching residue, which brings new pollution to the environment. It has to be cured and landfilled, which not only pollutes the environment, but also wastes resources.
- The titanium dioxide (TiO2) industry, a crucial component in the production of paints, plastics, paper, and other goods, has undergone significant transformations over the past few decades. These changes have been driven by advancements in technology, shifts in consumer preferences, and an increased focus on environmental sustainability. This article aims to explore the evolution and impact of TiO2 industry factories, providing insights into their current state and future prospects.
By doing so, we achieve cost reduction, increased film strength and improved fungicidal and algaecidal properties.
EFSA’s scientific advice will be used by risk managers (the European Commission, Member States) to inform any decisions they take on possible regulatory actions.
Currently, titanium dioxide as a food additive is classified as GRAS, or “generally recognized as safe.”
