- Titanium dioxide, also known as TiO2, is a versatile and widely used white pigment in various industries. As a key ingredient in paints, coatings, plastics, and even food and pharmaceutical products, titanium dioxide plays a crucial role in enhancing the appearance and performance of these products. With its excellent brightness, opacity, and UV-resistant properties, titanium dioxide is the go-to choice for manufacturers looking to achieve high-quality results.

- Lithopone, a crucial ingredient in the world of pigments and coatings, is a blend of zinc sulfide and barium sulfate. It's widely used in various industries due to its exceptional properties, such as high opacity, good whiteness, and heat resistance. Two popular grades of Lithopone are B301 and B311, both with a concentration of 28-30%. This article delves into the significance of these grades and the key suppliers in the market.
- The Regulation sets out a requirement ofcancer warning labels for mixtures in powder form containing 1% or more of titanium dioxide particles with an aerodynamic diameter of ≤ 10 µm. Although other forms and mixtures do not fall under this classification, there are specific warnings that need to be applied to those that contain more than 1% of titanium dioxide.

In 2017, the Scientific Committee on Consumer Safety (SCCS) warned that they should revise their recommendations if any new evidence emerges in the future related to the potentially harmful effects of TiO2NPs used in a sunscreen formulation or if they can penetrate the skin. In fact, our work could contribute to this matter because it evaluated the skin penetration of a particular kind of TiO2NPs. [8]

A few non-dietary studies have reported adverse effects in the gastrointestinal tract of laboratory animals given food-grade TiO2. However, these same effects were not seen when the same or higher doses of food-grade TiO2 were administered in the animals' diet. Dietary studies best reflect how humans are exposed to TiO2 from food. Thus, the Food Directorate placed the most emphasis on the results of these studies in the state of the science report.
Some dealers quoted prices that were significantly higher than expected, sending the domestic market to an almost three-year high. Meanwhile, a similar scenario was observed in the Indian market, where titanium dioxide prices (rutile grade) for rose by 8% from January to March. The increase was attributed to strong demand from the domestic paints and coatings sector as well as premium cargo from China.
Lithopone
In general, nanoparticles have been shown to accumulate in the body, particularly in organs in the gastrointestinal tract, along with the liver, spleen, and capillaries of the lungs.

Application:
1. Due to its rheological and optical properties, Lithopone offers technical and economic advantages wherever organic and inorganic resin systems need to be relatively highly pigmented for specific applications. Lithopone has therefore traditionally been used in putties, mastics, jointing and sealing compounds, primers, undercoats and marking paints. In powder coatings it is possible to replace TiO2 partially, very economically.
2. The low Mohs' hardness of Lithopone leads to low abrasiveness in comparison with TiO2.
3. Lithopone 30 % (= 30% zinc sulfide share) is proven to be of particular use as a TiO2 Substitute in thermoplastic masterbatches. Even at very high pigment loadings it disperses easily. A masterbatch containing 50 % TiO2 and 25 % Lithopone 30 % DS has the same hiding power as one containing 60 %TiO2. Cost savings are strongly related to the price ratio of Lithopone and TiO2 and the price of for example polyethylene or polypropylene.
4. The Lithopone batch has a much higher extrusion rate too. Furthermore the impact strength of many thermoplastics such as PP and ABS can be noticeably improved by using Lithopone as a TiO2 substitute. Generally spoken, Lithopone can be used at loadings up to 80 % by weight without causing polymer breakdown
The MBR9668 coating offers a range of advantages for manufacturers in the coatings industry. Primarily, its high hiding power allows for the efficient application of thinner layers, reducing material consumption and operational costs. This cost efficiency does not come at the expense of quality; the coating ensures a uniform finish with excellent opacity and gloss. Furthermore, the durability imparted by MBR9668 means that coatings will not only maintain their aesthetic appeal but also resist environmental stresses such as weathering, moisture, and chemical exposure.
Titanium can sometimes be detected by metal detectors. Whether a particular metal detector can detect titanium depends on the sensitivity and discrimination factors of that metal detector.
