Prof. Maged Younes, Chair of EFSA’s expert Panel on Food Additives and Flavourings (FAF), wrote of the decision: “Taking into account all available scientific studies and data, the Panel concluded that titanium dioxide can no longer be considered safe as a food additive. A critical element in reaching this conclusion is that we could not exclude genotoxicity concerns after consumption of titanium dioxide particles. After oral ingestion, the absorption of titanium dioxide particles is low, however they can accumulate in the body.”

What titanium dioxide is really emblematic of ... is the failure of FDA to look back at these old decisions and ask whether its decisions that were made in this case ... 56 years ago (in the 1966 approval) still hold up, he said.

  • With the growing demand for dyes and pigments in various industries, the need for a reliable and efficient titanium dioxide factory has become more important than ever. Titanium dioxide is a crucial ingredient in the production of dyes and pigments, as it provides excellent coverage and brightness to the final product.


    The produced barium sulfide enters the leacher, and the temperature is controlled above 65°C to obtain a barium sulfide content of 70%, and then enters the clarification barrel, add zinc sulfate for reaction after clarification, control the zinc sulfate content to be greater than 28%, pH=8~9, and obtain a mixture of barium sulfate and zinc sulfide with a density of 1.296~1.357 g/cm3.

    Lithopone, a zinc sulfide-based pigment, has been widely used in various industries due to its excellent whiteness, opacity, and chemical stability. Among the various grades of lithopone, 28B301 and 30B311 are particularly popular among manufacturers. In this article, we will provide a comprehensive guide on these two grades, including their properties, applications, and manufacturing processes. The benefits of wholesale TI02 powder extend to the health and beauty industry, where it is used as a key ingredient in sunscreens and cosmetics. Its ability to deflect and scatter UV radiation protects the skin from harmful rays while ensuring that cosmetic products maintain their intended appearance without discoloration. In addition to these traditional uses, titanium dioxide is gaining popularity in emerging fields such as photocatalysis and solar energy conversion

    Le lithopone est produit par coprécipitation de sulfure de baryum et de sulfate de zinc, le plus souvent en proportions équimolaires, puis grillage de la pulpe résultante4.

    The availability of other white pigments poses a major challenge for the Lithopone market during the forecast period. Other alternatives to Lithopone include Zinc White, Titanium Dioxide, Calcium Carbonate, Blanc Fixe, and Barytes. The use of TiO2 has reduced the commercial significance of the Lithopone in the pigments industry.

    Suppliers from China, India, and other countries with abundant mineral resources often offer competitive wholesale prices due to lower production costs In conclusion, Pretiox is a name synonymous with quality, innovation, and sustainability in the titanium dioxide industry.

    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. En este artículo se discute el descubrimiento del litopón fosforescente en dibujos a la acuarela por el artista americano John La Farge, fechados de 1890 a 1905, y la historia del litopón en la industria de los pigmentos a finales del Siglo XIX y principios del Siglo XX. A pesar de tener muchas cualidades deseables para su uso en pintura para acuarela o pinturas al óleo blancas, el desarrollo del litopón como pigmento para artistas fue obstaculizado por su tendencia a oscurecerse con la luz solar. Su disponibilidad para los artistas y su adopción por ellos sigue siendo poco clara, ya que por lo general los catálogos comerciales de los coloristas no eran explícitos al describir si los pigmentos blancos contenían litopón. Además, el litopón se puede confundir con blanco de plomo durante el examen visual, y su fosforescencia de corta duración puede ser fácilmente pasada por alto por el observador desinformado. A la fecha, el litopón fosforescente ha sido documentado solamente en otra obra mas: una acuarela por Van Gogh. Además de la historia de la fabricación del litopón, el artículo detalla el mecanismo para su fosforescencia, y su identificación con la ayuda de espectroscopía de Raman, y de espectrofluorimetría.

Apesar de ter muitas qualidades desejáveis para o uso em aquarela branca ou tintas a óleo, o desenvolvimento do litopônio como um pigmento de artistas foi prejudicado por sua tendência a se escurecer na luz solar. Sua disponibilidade para e uso por parte de artistas ainda não está clara, uma vez que os catálogos comerciais dos vendedores de tintas geralmente não eram explícitos na descrição de pigmentos brancos como algo que contém litopônio. Além disso, o litopônio pode ser confundido com o branco de chumbo durante o exame visual e sua fosforescência de curta duração pode ser facilmente perdida pelo observador desinformado. O litopônio fosforescente foi documentado em apenas um outro trabalho até hoje: uma aquarela de Van Gogh. Além da história da manufatura do litopônio, o artigo detalha o mecanismo para a sua fosforescência e sua identificação auxiliada pela espectroscopia de Raman e espectrofluorimetria.
