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.
TiO2 comes in many different forms. However, only a few of these forms are considered food-grade (acceptable to be added to food). Many studies that raised concern about the safety of TiO2, including the concern for genotoxicity, used forms of TiO2 that are not considered acceptable for use in food and have different properties than food-grade TiO2. Other studies did use food-grade TiO2, but took steps to break the material down into smaller particles than what would normally be found in food.
- The manufacturing process of TIO2 pigment involves either the sulfate or chloride process. Each method yields different types of TIO2 particles, which can affect the final product's performance and application. The sulfate process typically produces anatase, a crystalline form of TIO2, while the chloride process yields rutile, another crystalline form known for its superior durability and refractive index.

- In the area of photodynamic therapy, TiO2's photocatalytic properties have sparked interest
Lithopone 30% is the perfect solution for partial substitution of TiO2 in fillers due to its very soft nature and hardly any shrinkage properties.
TiO2 possesses different qualities depending on whether it is produced as a pigment or a nanomaterial. Both forms are tasteless, odourless and insoluble.
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, commented Matthew Wright, member of the EFSA's Food Additives and Flavourings Panel in a press statement.
- On the supply side, titanium is primarily produced from two sources ilmenite and rutile. Ilmenite is the most common source of titanium ore, while rutile is considered a higher-grade source. The supply of titanium ore is influenced by factors such as mining regulations, environmental concerns, and geopolitical events. Any disruptions in the supply chain can have a significant impact on prices.
For a review published in 2023 in the journal Environmental Pollution, researchers examined E171 as a possible factor promoting obesity-related metabolic disorders. Because gut microbiota play an important role in immune function maintenance and development, and because titanium dioxide as a food additive has been shown to alter gut microbiota, researchers wanted to review “the dysregulations along the gut microbiota-immune system axis after oral TiO2 exposure compared to those reported in obese or diabetic patients, and to highlight potential mechanisms by which foodborne TiO2 nanoparticles may increase the susceptibility to develop obesity-related metabolic disorders.” The study authors discovered recurrent changes in the gut microbiota composition when exposed to titanium dioxide nanoparticles, with an imbalance of intestinal symbiotic microbiota. These changes and imbalances were also reported and played a role in the development of obesity, the authors wrote. This highlights “foodborne TiO2 nanoparticles as an endocrine disruptor-like chemical promoting obesity-related disorders,” the authors concluded.
Micronized titanium dioxide doesn’t penetrate skin so there’s no need to be concerned about it getting into your body. Even when titanium dioxide nanoparticles are used, the molecular size of the substance used to coat the nanoparticles is large enough to prevent them from penetrating beyond the uppermost layers of skin. This means you’re getting the sun protection titanium dioxide provides with no risk of it causing harm to skin or your body. The coating process improves application, enhances sun protection, and prevents the titanium dioxide from interacting with other ingredients in the presence of sunlight, thus enhancing its stability. It not only makes this ingredient much more pleasant to use for sunscreen, but also improves efficacy and eliminates safety concerns. Common examples of ingredients used to coat titanium dioxide are alumina, dimethicone, silica, and trimethoxy capryl silane.

- In conclusion, nano titania is a versatile and effective additive for coatings, offering numerous advantages that contribute to the performance and sustainability of coatings. With China's focus on using nano titania in coatings, the coatings industry is poised to benefit from the unique properties and benefits of this innovative material.
Titanium dioxide is produced in two main forms. The primary form, comprising over 98 percent of total production, is pigment grade titanium dioxide. The pigmentary form makes use of titanium dioxide’s excellent light-scattering properties in applications that require white opacity and brightness.

- The price list for China lithopone B311 and B301 reflects their quality and performance characteristics. As a general rule, B311 is priced higher than B301 due to its superior hiding power and durability. However, both grades of lithopone offer good value for money and can help manufacturers achieve the desired aesthetics and performance in their products.
Titanium Dioxide prices in Germany increased by about 4% in the second quarter compared to what was seen in Q1 from historical price trends. Due to the restrictions on Russian energy imports brought on by the sanctions imposed by European countries, domestic production of TiO2 saw its costs surge even further. Additionally, the commodity's price was highlighted and its market expansion was supported by the upstream construction and automation sectors' buoyant demand.

Over the last several years, nanoparticles have come under scrutiny for adverse health effects. Nanoparticles are ultrafine particles between 1 to 100 nanometers in diameter. (To put this in perspective, the average human hair is around 80,000 nanometers thick.) Because of their size, which can be engineered and manipulated at the atomic or molecular level, nanoparticles exhibit unique physical, chemical, and biological properties. Titanium dioxide is one of the most commonly produced nanoparticles in the world.
- When selecting a supplier for titanium dioxide gravimetric analysis, it is important to consider factors such as the supplier's reputation, experience, and track record. A reputable supplier should have a good reputation in the industry and should be known for providing high-quality products that meet industry standards.
You see sometime ago, before they changed their warranty to exclude sunscreen damage, Bluescope Steel were getting countless warranty claims for peeling paint. All curiously shaped in fingerprint patterns around the edge of their metal sheets. This was a little perplexing & financially worrying for the bosses at Bluescope steel so they got some clever scientists to test the damaged roof sheets.
