  • This article discusses the discovery of phosphorescent lithopone on watercolor drawings by American artist John La Farge dated between 1890 and 1905 and the history of lithopone in the pigment industry in the late 19th and early 20th centuries. Despite having many desirable qualities for use in white watercolor or oil paints, the development of lithopone as an artists’ pigment was hampered by its tendency to darken in sunlight. Its availability to, and adoption by, artists remain unclear, as colormen's trade catalogs were generally not explicit in describing white pigments as containing lithopone. Further, lithopone may be mistaken for lead white during visual examination and its short-lived phosphorescence can be easily missed by the uninformed observer. Phosphorescent lithopone has been documented on only one other work-to-date: a watercolor by Van Gogh. In addition to the history of lithopone's manufacture, the article details the mechanism for its phosphorescence and its identification aided by Raman spectroscopy and spectrofluorimetry.

  • Drobne et al. used the terrestrial arthropod Porcellio scaber as a test organism for determining the cytotoxic effect of TiO2 NPs (anatase). The animals were exposed to TiO2 NPs of two different sizes (25 nm and 75 nm) in the concentration range 10–1000 μg TiO2/g dry food for 3 to 14 days. No adverse effects, such as mortality, body weight changes or reduced feeding, were observed. In fact, quite the opposite, an enhanced feeding rate, food absorption efficiency and increase in catalase activity were observed. The intensity of these responses appeared to be time- but not dose-dependent. It should also be noted that the concentrations tested in this study were much higher than the predicted concentration (4.8 μg/g soil) at high emission scenario of nano-sized TiO2. Using the same test organism another group showed that exposure to TiO2 NPs induced destabilization of cell membrane in the epithelium of digestive glands isolated from exposed animals. They also showed that this effect can be observed after just 30 minutes of exposure.

  • Another advantage of TIO2 is its excellent stability and resistance to fading. Unlike some other pigments, TIO2 does not degrade or change color over time, ensuring that your products maintain their quality and appearance for longer periods. This makes it an ideal choice for products that are exposed to sunlight or harsh environmental conditions.

  • Titanium dioxide is typically micronized and coated for use in cosmetics products. The micronizing makes this somewhat heavy-feeling ingredient easier to spread on skin, plus a bit more cosmetically elegant. Micronized titanium dioxide is much more stable and can provide better sun protection than non-micronized titanium dioxide.

  • In conclusion, the world of Titan Tio2 suppliers is dynamic, driven by continuous innovation and market demands. These suppliers play a crucial role in various industries, providing the essential ingredient that brings brightness, durability, and functionality to countless products. As the industry continues to evolve, suppliers will remain at the forefront, shaping the future of TiO2 applications and technologies.
  • In conclusion, the price per kilogram of titanium dioxide varies depending on several factors, including the production method, quality, purity, and demand. High-quality titanium dioxide produced through the chloride process tends to be more expensive than lower-quality titanium dioxide produced through the sulfate process. However, the sulfate process is more commonly used due to its lower cost and higher yield. As an essential pigment in various industries, titanium dioxide continues to play a crucial role in our daily lives.

  • Wegman’s puts titanium dioxide in its Original Macaroni and Cheese. Campbell’s Healthy Request Chunky Chicken Corn Chowder has it, as does Food Club’s Chunky New England Clam Chowder. Marzetti uses the color agent to brighten its Cream Cheese Fruit Dip. Dairy products usually don’t need titanium dioxide to look white, but Kroger has decided to add titanium dioxide to its Fat Free Half-and-Half. And titanium dioxide isn’t only in especially white or brightly colored foods: Little Debbie adds it to Fudge Rounds and many other products. According to the Food Scores database maintained by Environmental Working Group, more than 1,800 brand-name food products have titanium dioxide on their ingredients list. That said, it can still lurk as an unspecified “artificial color,” or labels might simply say “color added.”

  • In the manufacturing industry, sometimes many products require coloring, and the ideal coloring material is lithopone. This is a product manufactured through chemical methods. It is a mixture of barium sulfate and zinc sulfide. When the product contains more zinc sulfide, its effect will be better, that is, the coloring ability will be more stable. If you want to buy high-quality lithopone, you have to understand its properties and characteristics. Today’s article will give you a detailed understanding of lithopone.
