Titanium dioxide is an inert earth mineral used as a thickening, opacifying, and sunscreen ingredient in cosmetics. It protects skin from UVA and UVB radiation and is considered non-risky in terms of of skin sensitivity. Because it is gentle, titanium dioxide is a great sunscreen active for sensitive, redness-prone skin. It’s great for use around the eyes, as it is highly unlikely to cause stinging.
Titanium dioxide's journey into the food industry began with its classification as Generally Recognized As Safe (GRAS) by the US Food and Drug Administration (FDA). This status is granted after rigorous scientific evaluation, ensuring that the substance does not pose any significant health risks when used as intended. In Europe, the European Food Safety Authority (EFSA) also approves its use, but with specific guidelines on maximum levels.Hot Tags: c.i. 77115 lithopone / barium zinc sulfate / barium zinc sulfide / pigment whites zn2bas2o5 b301/b311 cas: 1345-05-7, China, suppliers, manufacturers, factory, customized, wholesale, price, free sample, Coconut Diethanol Amide, sodium hydrate liquid, TCCA granule, Ferric oxide Yellow, Aluminium Sulphate, 50 caustic soda
Application of lithopone in rubber and plastics application of lithopone in plastics and pigments lithopone can whiten and improve the compressive strength of products. Lithopone is easy to disperse rapidly, and thus the production process of this product is convenient, especially the molding, injection molding and actual operation process. It is worth mentioning that, with its organic chemical plasticity, it can also be integrated into the vulcanized rubber effect of recycled rubber.
The FDA's Code of Federal Regulations allows for the legal, regulated use of titanium dioxide in food products, under some restrictions.
While loose titanium dioxide presents a problem, titanium dioxide within sunscreen formulations presents a much safer option than conventional sunscreen chemicals like oxybenzone and octinoxate. However, titanium dioxide may become dangerous when it is nanoparticle size. Generally, nanoparticles can be 1000 times smaller than the width of a human hair. Despite nanoparticles becoming increasingly common across industries, they have not been properly assessed for human or environmental health effects, nor are they adequately regulated. Researchers don’t quite understand the impacts nanoparticles could have on human health and the environment. However, because of their infinitesimally small size, nanoparticles may be more chemically reactive and therefore more bioavailable, and may behave differently than larger particles of the same substance; these characteristics may lead to potential damage in the human body or ecosystem.

Résumé–Cet article traite de la découverte de lithopone phosphorescent sur des dessins à l'aquarelle, datés entre 1890 et 1905, de l'artiste Américain John La Farge et de l'histoire du lithopone dans l'industrie des pigments à la fin du 19e et au début du 20e siècle. Malgré de nombreuses qualités souhaitables pour une utilisation en tant que blanc dans les aquarelles et les peintures à l'huile, le développement du lithopone comme pigment pour artistes a été compliqué de par sa tendance à noircir lorsqu'il est exposé au soleil. Sa disponibilité et son usage par les artistes demeurent incertains parce que les catalogues des marchands de couleurs n'étaient généralement pas explicites à indiquer si les pigments blancs contenaient du lithopone. De plus, lors d'un examen visuel, le lithopone peut être confondu avec le blanc de plomb et sa phosphorescence de courte durée peut facilement être ignorée par l'observateur non averti. À ce jour, le lithopone phosphorescent a seulement été documenté sur une autre œuvre: une aquarelle de Van Gogh. En plus de l'histoire de la fabrication du lithopone, cet article décrit le mécanisme de sa phosphorescence et son identification à l'aide de la spectroscopie Raman et de la spectrofluorimétrie.
Furthermore, Cristal Global, a Saudi-based titanium dioxide manufacturer, also supplies food-grade anatase TiO2. Their product range, including Tiona series, is globally recognized for its high brightness and excellent dispersion properties, making it suitable for diverse food applications. Moreover, China's stringent environmental regulations have driven the industry to adopt more eco-friendly production methods. Many manufacturers have invested in advanced technologies to reduce waste, minimize energy consumption, and lower emissions during the production of R996. This commitment to sustainability aligns with the global trend towards green manufacturing.The safety of the food additive E 171 was re-evaluated by the EFSA ANS Panel in 2016 in the frame of Regulation (EU) No 257/2010, as part of the re-evaluation programme for food additives authorised in the EU before 20 January 2009.
The lack of clear regulations and controls explains that P25TiO2NPs are still found in many of the commercialized sunscreens in the market. Some of them are coated to reduce the photoactivity of the anatase form, which is known to be responsible for tissue damage, but not enough studies were made on these coated forms. The anatase photoactivity could trigger the production of reactive oxygen species (ROS) generation, as it was stated before. The ROS are chemically reactive species containing oxygen, such as peroxides, superoxide, hydroxyl radical, and singlet oxygen. They are regularly produced in the biological milieu and counterbalanced by physiological antioxidant defense mechanisms. However, an abrupt increase of ROS may result in non-reversible damage to the skin cells. The effects of coated and uncoated P25TiO2NPs need therefore to be studied, and articles on this topic present different conclusions. [11], [12], [13] Recent literature on this topic found that TiO2NPs inhalation provokes serious genotoxicity and DNA damage [14], [15], [16], [17]. On the other hand, some studies in rats have reported no significant harm to genetic material [18], [19], [20], [21], [22].
Wholesale TI02 powder plays a critical role in photocatalysis, a process that harnesses sunlight to drive chemical reactions
In a 2020 study published in the Journal of Trace Elements in Medicine and Biology, researchers conducted an in vitro experiment to analyze the effects of TiO2 nanoparticles on a human neuroblastoma (SH-SY5Y) cell line. The scientists evaluated “reactive oxygen species (ROS) generation, apoptosis, cellular antioxidant response, endoplasmic reticulum stress and autophagy.” The results showed that exposure to the nanoparticles “induced ROS generation in a dose dependent manner, with values reaching up to 10 fold those of controls. Nrf2 nuclear localization and autophagy also increased in a dose dependent manner. Apoptosis increased by 4- to 10-fold compared to the control group, depending on the dose employed.”
Another crucial property of TiO2 is that it can show photocatalytic activity under UV light. This makes it effective for environmental purification, for different kinds of protective coatings, sterilisation and anti-fogging surfaces, and even in cancer therapy.
A 2023 study published in the journal Particle and Fibre Toxicology set out to examine the impact of titanium dioxide nanoparticles in mice “on the course and prognosis of ulcerative colitis,” by creating an ulcerative colitis disease model. Researchers found that the titanium dioxide nanoparticles significantly increased the severity of colitis. They also “decreased the body weight, increased the disease activity index and colonic mucosa damage index scores, shortened the colonic length, increased the inflammatory infiltration in the colon.” Researchers concluded: “Oral intake of TiO2 nanoparticles could affect the course of acute colitis in exacerbating the development of ulcerative colitis, prolonging the ulcerative colitis course and inhibiting ulcerative colitis recovery.”
Barium sulfate, commonly known as baryte, is a versatile mineral that finds applications in various industries. It is an essential component in the production of paints, plastics, rubber, and paper, among others. The demand for barium sulfate has been steadily increasing due to its unique properties, such as high brightness, chemical inertness, and excellent thermal stability. In conclusion, TiO2 is a versatile material that plays a crucial role in many industries, and choosing the right supplier is essential to ensure the quality and performance of your products. By working with top TiO2 suppliers like Tronox and Chemours, companies can benefit from high-quality TiO2 products that meet the highest industry standards.

Cleaning and personal care sectors are other significant consumers of sodium bicarbonate. Its alkaline properties make it an effective cleaner and deodorizer, while its mild abrasive nature makes it suitable for use in toothpaste and soaps. Suppliers in these areas often provide bulk quantities and tailor-made solutions for commercial and industrial use.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.
TiO2 pigment factories also focus on environmental sustainability and strive to minimize their environmental impact. They implement measures such as waste management, recycling, and the use of eco-friendly production processes to reduce their carbon footprint. Some factories also use renewable sources of energy, such as solar or wind power, to power their operations and reduce their dependence on fossil fuels.
