The lack of clear regulations and controls explains that P25TiO2NPs are still found in many of the commercialized sunscreens in the market. Some of them are coated to reduce the photoactivity of the anatase form, which is known to be responsible for tissue damage, but not enough studies were made on these coated forms. The anatase photoactivity could trigger the production of reactive oxygen species (ROS) generation, as it was stated before. The ROS are chemically reactive species containing oxygen, such as peroxides, superoxide, hydroxyl radical, and singlet oxygen. They are regularly produced in the biological milieu and counterbalanced by physiological antioxidant defense mechanisms. However, an abrupt increase of ROS may result in non-reversible damage to the skin cells. The effects of coated and uncoated P25TiO2NPs need therefore to be studied, and articles on this topic present different conclusions. [11], [12], [13] Recent literature on this topic found that TiO2NPs inhalation provokes serious genotoxicity and DNA damage [14], [15], [16], [17]. On the other hand, some studies in rats have reported no significant harm to genetic material [18], [19], [20], [21], [22].

 With the development of science and technology, various pigments have emerged. Inorganic pigments are facing serious challenges. Nanomaterials are a new class of materials with mesoscopic dimension developed at the end of the 20th century. They are now developing in a low-dimensional and complex direction. . In recent years, nano-Lide powder has been put into industrial production. The zinc sulphate solution is prepared in the same way as the traditional method. In the organic phase (such as benzene), the production cost is high, the wastewater is difficult to recycle, the organic solvent in the production process and the final immersion. Slag is likely to cause environmental pollution, and its development is severely limited.
