The rutile form of titanium dioxide is preferred over the anatase form because it offers superior hiding power and greater stability under various environmental conditions. Its coarser particle size and higher refractive index contribute to its excellent opacity, making it an ideal choice for hiding surfaces and providing a strong base for color consistency in coated products Its coarser particle size and higher refractive index contribute to its excellent opacity, making it an ideal choice for hiding surfaces and providing a strong base for color consistency in coated products Its coarser particle size and higher refractive index contribute to its excellent opacity, making it an ideal choice for hiding surfaces and providing a strong base for color consistency in coated products Its coarser particle size and higher refractive index contribute to its excellent opacity, making it an ideal choice for hiding surfaces and providing a strong base for color consistency in coated productsgood whiteness titanium dioxide rutile factory for coating factory.

One of the main applications of titanium dioxide in paper is in the production of high-quality coated papers. Titanium dioxide is often added to the coating formulations to enhance the whiteness and brightness of the paper surface. This helps to improve the print quality of the paper, as it provides a smooth and even surface for ink to adhere to. The high opacity of titanium dioxide also helps to prevent show-through, making the printed text or images more vibrant and legible.

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.
