The global market for lithopone pigment is projected to grow steadily in the coming years, driven by the increasing demand for high-quality paints, coatings, and plastics. Factories that specialize in the production of lithopone pigment are poised to capitalize on this growth by expanding their production capacity and investing in new technologies to improve efficiency and quality. This will ensure that manufacturers have access to a reliable supply of lithopone pigment to meet their production needs.

Titanium dioxide (TiO2) is a naturally occurring mineral that is mined from the earth, processed and refined, and added to a variety of foods, as well as other consumer products. White in color, it is used to enhance the color and sheen of certain foods and is also key for food safety applications. In its natural state it exists in different bulk crystalline forms, such as anatase and rutile, but during processing it is ground into a very fine powder.

As mentioned above, these oxide NPs are harmful in part because both anatase and rutile forms are semiconductors and produce ROS. Particularly, P25 kind has band-gap energies estimated of 3.2 and 3.0 eV, equivalent to radiation wavelengths of approximately 388 and 414 nm, respectively. Irradiation at these wavelengths or below produces a separation of charge, resulting in a hole in the valence band and a free electron in the conduction band, due to the electron movement from the valence to conduction bands. These hole–electron pairs generate ROS when they interact with H2O or O2 [43,44]. It was described that they can cause an increase in ROS levels after exposure to UV-visible light [45]. The NBT assay in the studied samples showed that bare P25TiO2NPs produce a large amount of ROS, which is drastically reduced by functionalization with vitamin B2 (Fig. 5). This vitamin, also known as riboflavin, was discovered in 1872 as a yellow fluorescent pigment, [46] but its function as an essential vitamin for humans was established more than sixty years later, and its antioxidant capacity was not studied until the end of the XX century [47,48]. This antioxidant role in cells is partially explained because the glutathione reductase enzyme (GR) requires it for good functionality. This enzyme is the one in charge of the conversion of oxidized glutathione to its reduced form which acts as a powerful inner antioxidant and can quench the ROS [49,50]. The cost of this action is that the glutathione is converted to the oxidized form and needs to be recovered by the GR. Consequently, the cells need more vitamin B2. Another glutathione action is the protection against hydroperoxide. This activity is also mediated by riboflavin. Therefore, local delivery of this vitamin seems to significantly help the cells in their fight to keep the oxidative balance, once they are exposed to high levels of ROS.

According to the feedback of the manufacturers, the new mainstream factory has risen, and the focus of the overall market transaction has moved up. From the perspective of demand side, the current overall intention of the terminal to replenish inventory before the holiday is OK; From the supply side, some mainstream manufacturers have increased the load, and the actual output of the industry is stable. Most factories report a new price of around 17,000 yuan/ton, and some plastics and papermaking related downstream feedback some tight models are more expensive. Recent titanium dioxide raw material price trend is strong, titanium dioxide price support is more stable, comprehensive market factors, the current titanium dioxide market to maintain a price state.
