Abstract
Cosmetics are an integral part of daily life. Nowadays, cosmetics are endowed with more healthcare functions while meeting people's needs for beauty enhancement. Nano-titanium dioxide plays a crucial role in their formulation because of its antibacterial and anti-inflammatory properties. As a new type of nanomaterial, nano-titanium dioxide has excellent properties. This paper explores the properties, preparation methods, applications, and potential hazards associated with nano-titanium dioxide in cosmetics. The study highlights its strong ultraviolet (UV) shielding capabilities, which are used in sunscreen products. The nano-titanium dioxide has good dispersibility and weather resistance. The preparation methods included sol-gel, hydrothermal, vapor deposition, and oxide reduction methods. The paper further discusses the use of nano-titanium dioxide in various cosmetic products such as sunscreens, lotions, and gels. Despite its advantages, the paper also displays safety concerns related to skin exposure, inhalation, and oral intake of nano-titanium dioxide. The material poses certain risks, its beneficial properties make it a valuable component in the cosmetic industry. The nano-titanium dioxide significantly enhances the functionality of cosmetics. This work contributes to its widespread use in the future.
