The vitaminC@P25TiO2NPs, on the other hand, were obtained through an optimized method based on Mallakpour et al. [27]. Initially, 0.02 g of P25TiO2NPs were dispersed in 1 mL of ultrapure water and stirred in a Vortex. Next, 100 μL of HCl (0.01 M) were added (pH 2) to 100 uL of P25TiO2NPs to avoid gel formation. Then, 100 μL of vitamin C dissolved in ultra-pure water (5.0 × 10−3 M) solution were added to the mixture and was ultrasonicated for 30 min. Finally, vitamin C was added in excess to gain a beige-orange color suspension, and the ultrasonication continued for another 30 min. The pellet obtained after centrifuging the suspension for 10 min at 4500 rpm was resuspended in ultrapure water, centrifuged again, and then lyophilized.

Because of health risks, France banned titanium dioxide as a food additive in 2020. Two years later the European Union also banned titanium dioxide as a food additive.
The toxicity of P25TiO2NPs under UV radiation could be even higher when combined with other usual components of sunscreens Indeed, Soler de la Vega et al. advise that combination with parabens increases the toxicity of the final cosmetic mixture [53].

China is known for being one of the largest producers and consumers of titanium dioxide (TiO2) in the world. TiO2 is a white pigment that is commonly used in paints and inks due to its excellent opacity, brightness, and UV protection properties.

The first step in obtaining titanium dioxide typically begins with the mining of ilmenite, rutile, and anatase – minerals that contain titanium. These minerals are extracted from the earth through open-pit or underground mining methods. Once mined, they undergo beneficiation processes such as crushing, grinding, and gravity separation to concentrate the titanium-bearing ore.
