Pigmentary TiO2 particles are approximately 200-350nm in dimension and this form accounts for 98 percent of total production. It is used mainly for light scattering and surface opacity applications. It is used as a base for various colour paints or as a standalone ‘brilliant’ white.
Some consumer advocacy groups and health agencies — particularly, those at the Environmental Working Group — have been pushing federal officers at the Food and Drug Administration (FDA) to reconsider their existing rules on the additive, which is commonly found in processed snacks and sweets.
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.
Nano titanium dioxide is a versatile material that is used in many different industries due to its unique properties. As a leading manufacturer of nano titanium dioxide, we pride ourselves on producing high-quality products that meet the needs of our customers.
② Plastics: At present, it is the second largest user of titanium dioxide pigments, accounting for about 20% of the total demand for titanium dioxide. The amount of titanium dioxide used in plastic products will vary with the use requirements, generally between 0.5% and 5%. According to data from the National Bureau of Statistics, the production of plastic products in China increased from 57.81 million tons in 2012 to 81.84 million tons in 2019, with a compound annual growth rate of 5.1%. The amount of titanium dioxide increases accordingly.
Let's get into some history. Capsaicin was first extracted in 1816 by Christian Fridrich. Further work by John Clough Thresh led to its naming in 1876, but it wasn´t until 1898 that Karl Micko isolated the compound in pure crystalline form. A century later, in 1997, David Julius discovered and cloned the cellular receptor for capsaicin, and brought a new level of understanding on how capsaicin works. We´ll get more into this science in the second part of this blog.

Food scientists classify cayenne as a medium-hot variety of pepper. According to Colorado State University Extension, this spice clocks in at between 30,000 and 50,000 units on the Scoville scale, a method of measuring the amount of capsaicin in a hot pepper.
Thus, please don't be confused when I use the terms hot or spicy paprika and Hungarian paprika interchangeably.
