cas: 13463-67-7 titanium dioxide powder manufacturer

In order to contribute with experimental evidence that could help to achieve a better understanding of the field for future regulation, in the present work, the biocompatibility of commercial P25TiO2NPs (one type of TiO2NPs used in sunscreen formulations) and two novel functionalized P25TiO2NPs were evaluated under solar simulated irradiation. White light, generated by red, blue, and yellow LEDs, together with UV ones, was chosen to simulate the solar spectra. Functionalization of TiO2NPs was made with antioxidant vitamins in order to prevent the expected photo-initiated ROS production when nanoparticles are exposed to the simulated solar spectra. Vitamin B2 (riboflavin) and vitamin C were chosen to carry out the functionalization because they are water-soluble, low-cost, and are a constitutive part of biological processes. In addition, it is known that both have the potential to prevent macromolecular oxidation by ROS [23][24][25][26].

One of the key factors affecting TiO2 manufacturing is the choice of raw materials. Rutile and anatase are the two most common forms of TiO2, each with its own unique properties and applications. Rutile is known for its higher refractive index and hardness, making it suitable for use in coatings, plastics, and other high-performance applications. Anatase, on the other hand, has better photocatalytic activity and is often used in environmental protection and solar energy applications.
