anatase tio2 pigment powder factories

Rutile TiO2's significance extends beyond its aesthetic benefits. In the pigment industry, it is the most widely used white pigment due to its superior whiteness and brightness. It imparts excellent covering power and gloss to paint, plastics, and paper, enhancing their overall quality. Moreover, its UV absorbing capabilities make it an essential component in sunscreen formulations, protecting the skin from harmful ultraviolet radiation.

The vitaminC@P25TiO2NPs, on the other side, did not have any effect on cell protection against ROS. This might be due to the fact that vitamin C, a well-known scavenger of ROS, could behave as prooxidant and even promote ROS and lipid peroxidation [39]. It was recently described that at small concentrations of vitamin C, the prooxidant effects dominate; while in large concentrations the antioxidant ones predominate [40]. The effect also depends on the cell state and the interaction of vitamin C with light. In this case, ascorbic acid may act as an antenna to harvest visible light when conjugated to P25TiO2NPs. Indeed, it was previously found that this combination (in some ratios) could have an improved photocatalytic activity, possibly due to a red shift in its light absorbance [41]. Further studies on vitaminC@P25TiO2NPs were not conducted, because of the poor antioxidant capacity [42].

In conclusion, while both lithopone and titanium dioxide have their advantages and disadvantages, TiO2 appears to be the better choice for most applications. Its superior whiteness, UV protection properties, and chemical stability make it a popular choice in the paint, plastics, and paper industries. However, for applications where cost and safety are primary concerns, lithopone may still be a viable option. Ultimately, the choice between these two pigments will depend on the specific requirements of the application and the desired balance of performance and cost.
