There is some concern regarding skin and intestinal absorption of titanium dioxide nanoparticles, which are less than 100 nm in diameter.
Once the raw materials are ground to the proper size, they are subjected to a series of chemical treatments to further enhance the performance of the pigment. These treatments help to improve the dispersibility, hiding power, and brightness of the lithopone 28-30%, making it suitable for a wide range of applications.
Manufacturers of TIO2 pigment are constantly exploring ways to improve these processes to enhance the pigment's properties, reduce production costs, and minimize environmental impact. Innovations such as nanotechnology have allowed for the creation of nano-sized TIO2 particles that offer improved performance characteristics, including better UV protection and higher transparency in certain applications.

Anatase, a crystalline form of titanium dioxide, has been garnering significant attention due to its unique optical and electronic properties. This compound is widely used in various applications such as photocatalysts, solar cells, and gas sensors. Given its increasing demand and limited supply, the anatase price has become a topic of interest for both producers and consumers.
Infrared analysis showed that the characteristics bands for the bare nanoparticles are still exhibited in the vitamins@P25TiO2NPs spectra, such as a wide peak in 450–1028 cm−1 related to the stretching vibration of Ti-O-Ti and other peaks in 1630 cm−1 and 3400 cm−1, which represent the surface OH groups stretching. The IR spectrum of vitaminB2@P25TiO2NPs showed signs of binding between compounds. The OH bending peak (1634 cm−1) corresponding to bare nanoparticles disappeared, and the NH2 bending band characteristic of vitamin B2 appeared (1650 cm−1). The IR spectrum of vitaminC@P25TiO2NPs also showed signs of successful functionalization. Bands at 1075 cm−1; 1120 cm−1; 1141 cm−1 were observed, which are originated by C
O-C vibrations present in the vitamin C. The intense band at 1672 cm−1 is attributed to the C = O stretching in the lactone ring while the peak at 1026 cm−1 is ascribed to the stretching vibration Ti-O-C. Wide bands at 3880–3600 cm−1 are related to stretching vibration OH groups, but those disappear in the modified nanoparticles spectrum. These observations confirm the interactions between the P25TiO2NPs and the vitamins [35].
