Firstly, it's essential to understand what makes lithopone a preferred choice for many consumers. Unlike traditional lead-based paints, lithopone is free from harmful substances, making it an environmentally friendly option. Its superior coverage means that fewer coats are needed to achieve the desired finish, which translates to cost savings for homeowners and contractors alike. Moreover, lithopone's brightness index is higher than most pigments, ensuring a vibrant and long-lasting appearance on walls.

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.

It offers several advantages in various applications. Its excellent opacity and brightness make it a popular choice in the production of paints, coatings, and printing inks, providing a cost-effective alternative to titanium dioxide. Lithopone's chemical stability enhances its durability in outdoor environments, making it suitable for outdoor coatings. Additionally, its low reactivity and compatibility with other pigments contribute to its versatility. Beyond coatings, lithopone finds utility in plastics, rubber, and paper industries. Overall, its multifaceted advantages and broad applications underscore this compound's significance in diverse industrial sectors.
