Titanium Dioxide A Versatile Chemical Compound In addition to its optical properties, industrial grade titanium dioxide also offers excellent chemical resistance, durability, and weatherability, making it suitable for outdoor applications where exposure to harsh environmental conditions is a concern. With our advanced manufacturing processes, we can produce titanium dioxide that meets the highest standards of quality and reliability, ensuring that our customers can trust our products to perform consistently in their applications.

What's the deal with titanium dioxide?
  • no evidence of cancer or other adverse effects in mice and rats exposed to high concentrations of food-grade TiO2 (long-term or lifetime study)
    •  To address these challenges, researchers are exploring alternative production methods that are more energy-efficient and environmentally friendly. For example, the use of solar energy to power the oxidation of titanium ore has been proposed as a way to reduce the energy consumption of the sulfate process. Other approaches include the development of new catalysts that can replace sulfuric acid in the oxidation step, as well as the exploration of bio-based feedstocks for TiO2 production.

    •  In the world of rubber manufacturing, the quest for innovative materials and additives that can enhance product performance and longevity is never-ending. One such groundbreaking additive is lithopone, a versatile pigment that has revolutionized the rubber industry in numerous ways. This article delves into the characteristics, applications, and advantages of using lithopone for rubber. Wholesale pigment suppliers are at the heart of distributing this miraculous material, ensuring a steady flow of titanium dioxide to meet global demands. They handle the complex task of matching the specific requirements of different sectors, whether it’s the precise particle size for optimal gloss in cosmetics or the high purity levels needed for certain food grade applications.

    2. What foods contain titanium dioxide?

    According to the EFSA's Expert Panel on Food Additives and Flavorings 2021 opinion regarding titanium dioxide, it could not rule out a concern for genotoxicity from ingestion of the material based on a perceived gap in data on this risk, which serves as the basis for current ban, said a March report on the decision.

    While the conclusions of the EU expert panel were considered in this report, Health Canada's Food Directorate conducted its own comprehensive review of the available science. This included evaluating new scientific data that addressed some of the uncertainties identified by the EU expert panel and were not available at the time of their review.    

     Titanium dioxide, a compound as ubiquitous in our daily lives as it is in the annals of science, is more than just a mere chemical substance. It is a testament to the marvels of chemistry and its profound impact on various industries. With the formula TiO2, titanium dioxide serves as a cornerstone for products ranging from paint to sunscreen, demonstrating both its versatility and importance.
     At present, Lide powder is mainly produced in China. Most of the domestic Lide powder production is still using traditional methods. The main raw materials are zinc oxide, sulfuric acid and barium sulfide (barite and coal are produced by high temperature reduction). Zinc 45% ~ 70%. The traditional method for producing the Liede powder process is to use zinc bakelite containing more than 45% zinc as a raw material to be leached with sulfuric acid to obtain a crude zinc sulfate solution, and then to remove iron by potassium permanganate, and then replace the heavy metal with zinc powder and filter to obtain zinc sulfate. The refined liquid is further subjected to metathesis reaction, pressure filtration, calcination, rinsing, drying, and pulverization with strontium sulfide to obtain a series of different types of lindose powder containing zinc sulfide of 30% or more. The whole process is carried out in an acidic (ra<7) environment, which consumes a large amount of sulfuric acid. The sulfuric acid has strong corrosiveness and requires high production equipment. The final discharged slag is acidic slag, which brings new pollution to the environment. High requirements, high production costs, and poor quality of the products obtained.

    Production

    In a 2016 study published in Scientifica (Cairo), Egyptian researchers examined the effects of titanium dioxide nanoparticles on the organs of mice by orally administering the food additive daily, for five days. The results showed that the exposure produced “mild to moderate changes in the cytoarchitecture of brain tissue in a time dependent manner.” Furthermore, “Comet assay revealed the apoptotic DNA fragmentation, while PCR-SSCP pattern and direct sequencing showed point mutation of Presenilin 1 gene at exon 5, gene linked to inherited forms of Alzheimer’s disease.” The researchers wrote: “From these findings, “the present study concluded that TiO2NPs is genotoxic and mutagenic to brain tissue which in turn might lead to Alzheimer’s disease incidence.”

    Tioxide process. This process is similar to that used to produce fumed silicas. Ultra-low particle size titanium dioxide (15-35 nm) is obtained for use as photocatalyst or UV absorber (for instance in sun protective creams).
