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].

However, China's dominance in rutile titanium dioxide manufacturing is not without challengeschina rutiletitanium dioxide manufacturer. Environmental concerns have become a major issue in recent years, as the industry's rapid expansion has put pressure on natural resources and ecosystems. To address these challenges, Chinese authorities have implemented stricter environmental regulations and encouraged the adoption of cleaner production technologies. These efforts have helped to improve the industry's environmental performance and ensure sustainable growth.
