- In the world of industrial pigments, lithopone stands as a cornerstone due to its versatility and quality. Lacking in toxicity and boasting excellent covering power, it has been a favorite for paint manufacturers for over a century. As we delve into the renaissance of lithopone factories, it's imperative to understand not just the product itself but also the innovation sparking this resurgence.
- 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.
- Several global companies specialize in the production and supply of rutile TiO2. These suppliers invest heavily in research and development to improve the purity and performance of their products. They also offer tailored solutions, catering to the specific needs of their clients. Some well-established suppliers include Cristal Global, Tronox, and Evonik, among others, each known for their commitment to quality and customer satisfaction.
- In conclusion, wholesale colloidal silicon dioxide is a valuable and versatile material with a wide range of applications in various industries. Its unique properties make it an essential ingredient in food, pharmaceuticals, cosmetics, and industrial products. As technology continues to advance, the demand for colloidal silicon dioxide is expected to increase, driving further innovation and development in its use.
Bluescope Steel now specifically mention sunscreen & titanium dioxide use in their warranty so they no longer have to pay out for the damage caused by a little bit of transferred sunscreen residue.
Therefore, today, they only recommend limiting titanium dioxide inhalation in industries with high dust exposure, such as paper production (11).

When E171 is part of a food product, it passes through the digestive system without causing harm because E171 combines with the other ingredients.
While IARC listed titanium dioxide as “possibly carcinogenic to humans,” they also add that “there is inadequate evidence in humans for the carcinogenicity of titanium dioxide.” Of the four human studies that they reviewed, only one showed a potential risk for occupational workers inhaling titanium dioxide particles and lung cancer, while the other three showed no risk for cancer at all. And it’s key to note that IARC did not assess the effects of titanium dioxide found in foods.
Other food products that list titanium dioxide are Lucerne cottage cheese, Beyond Meat's chicken plant-based tenders, Great Value ice cream and Chips Ahoy! cookies.

The morphology of vitaminB2@P25TiO2NPs is coherent with the description of Degussa P25 typical population. Size distribution histograms were made from manual measures of the nanoparticles observed in SEM micrographs using ImageJ®. This data showed that more than 70% is anatase (between 20 and 60 nm) with a minor amount of rutile characteristic bars (between 80 and 100 nm) and a small amount of amorphous phase (<40 nm) [36]. Further analysis of the same sample areas with an EDS probe demonstrated the presence of organic material composed of C and O (Fig. 2). This material was found homogeneously distributed on the surface of the different shapes of P25TiO2NP, not in the background, indicating a specific interaction that could be attributed to the functionalization of the P25TiO2NPs with vitamin B2.

Available studies in humans and postmortem analysis of tissues suggested that the oral bioavailability of titanium dioxide in humans is very low. JECFA noted that there are currently no epidemiological studies that allow any conclusions to be drawn with respect to an association between dietary exposure titanium dioxide and human health effects.
