Having thus described the origin and uses of the pigment, we now come to the question, what is lithopone? It is, in short, a chemical compound usually consisting of 30.5 per cent zinc sulphide, 1.5 per cent zinc oxide and 68 per cent barium sulphate, but these proportions vary slightly in the different makes. Lithopone of this composition is sold as the highest grade, either as red seal or green seal, as it best suits the idea of the manufacturer. Many manufacturers, especially in Europe, sell and also export other brands under other seals, containing 24, 20, 18 and as little as 12 per cent of zinc sulphide with very small percentages of zinc oxide, the balance being usually barium sulphate, but sometimes certain portions of China clay or gypsum (calcium sulphate) or whiting (calcium carbonate). Such brands are not a chemical compound, but mechanical mixtures of the chemically compounded lithopone and the admixtures referred to.

While this ruling from the EU General Court doesn’t immediately change the regulations surrounding titanium dioxide, nor does it change the ban that went into place in 2022, it does put the ingredient back in the spotlight.
 
In the coming months, we will see how the ruling impacts the regulations around titanium dioxide (E171), and we’ll see if the European Food Safety Authority (EFSA) will take another look at the body of scientific evidence used to justify the current ban on E171 in foods and pharmaceuticals.

 However, the use of titanium dioxide in plastic factories requires careful consideration of particle size, surface treatment, and dispersion techniques to achieve optimal performance. Manufacturers must balance the desired properties against potential challenges such as agglomeration or increased viscosity during processing.

Le lithopone, blanc de lithopone ou blanc de Comines est un pigment blanc composé d'un mélange de sulfure de zinc et de sulfate de baryum, généralement en proportions équimolaires.

 Safety concerns have been raised about the nanoparticles of titanium dioxide due to their potential to penetrate cells and induce adverse health effects. However, current research indicates that these risks are minimal when appropriate safety measures are taken during production and handling.

China is at the forefront of the titanium dioxide industry, with manufacturers like Lomon producing high-quality products such as R996 grade titanium dioxide for the paint industry. Titanium dioxide is a crucial ingredient in paint production, as it provides opacity, brightness, and UV protection to the finished product.

  • New product development
    •  Another advantage of using nano titania in coatings is its antimicrobial properties. Nano titania exhibits antibacterial and antifungal properties, making coatings containing nano titania suitable for applications requiring cleanliness and hygiene, such as healthcare facilities, food processing plants, and public spaces.

    The ingredient in question? Titanium dioxide.

     In conclusion, dioxygen dioxide (CAS 13463-67-7) is a versatile compound with a significant presence in the wholesale market. Its role in sanitation, medicine, and environmental preservation underscores its value and the need for a robust wholesale network. As technology advances and sustainability becomes a priority, the demand for ozone is likely to continue to grow, shaping the future of this dynamic market.

    In a 2019 study published in the journal Nanotoxicology, researchers recreated the first phase of digestion in mice and fed them titanium dioxide, then examined whether accumulation occurred in the organs. Researchers wrote: “Significant accumulation of titanium was observed in the liver and intestine of E171-fed mice; in the latter a threefold increase in the number of TiO2 particles was also measured. Titanium accumulation in the liver was associated with necroinflammatory foci containing tissue monocytes/macrophages. Three days after the last dose, increased superoxide production and inflammation were observed in the stomach and intestine. Overall, [this] indicates that the risk for human health associated with dietary exposure to E171 needs to be carefully considered.”

    Dongfang Titanium Industry R-5568 titanium dioxide with zinc salt stabilizer, zirconium, aluminum, silicon coating. It has the characteristics of high blue phase, easy dispersion, high weather resistance, high hiding power, low oil absorption, good system compatibility, and excellent processing rheology. It is a high-quality titanium dioxide for plastics. Dongfang Titanium R-5568 titanium dioxide is recommended to be widely used in polyolefin, PVC, ABS, PS and other color masterbatches, profiles, plates and pipes, and can also be used in leather color paste, oily paint and other industries.

    In addition to these uses, titanium dioxide is also used in:

     In conclusion, TIO2 procurement and manufacturing is a dynamic sector that continually adapts to changing market dynamics, technological innovations, and environmental considerations. Companies that can balance cost-effectiveness, quality assurance, and sustainability will be well-positioned to thrive in this competitive landscape. As the world becomes more environmentally conscious, the future of TIO2 manufacturing is likely to pivot towards cleaner, more efficient, and sustainable production methods. Anatase, one of the three main crystalline forms of TiO2, possesses a unique structure that enhances its performance in numerous applications. With a high specific surface area and excellent thermal stability, B101 Anatase powder exhibits superior photocatalytic efficiency compared to other forms, such as Rutile and Brookite. This attribute makes it a popular choice for use in air purification, water treatment, and self-cleaning surfaces.
