The production of ROS was studied on white blood cells as a model to screen the effect on eukaryotic cells after being exposed to samples and solar simulated irradiation (according to the level of penetration under the skin). For that purpose, the leukocytes were separated from anticoagulated fresh blood using the Ficoll-Hypaque reactive in a well-known technique [33]. Then, 50 μL of suspensions of P25TiO2NPs (0.2 mg/mL and 0.02 mg/mL), vitaminB2@P25TiO2NPs (0.2 mg/mL and 0.02 mg/mL) and vitamin B2 (0.2 mg/mL and 0.02 mg/mL) were prepared and mixed with 50 μL of white blood cells suspension. A solution of 3% H2O2 was used as positive control and PBS as negative control. Then, the samples were irradiated using the LED panel for 3 and 6 h to simulate the light penetration into the skin. Also, a set of samples was kept in the dark as control. Finally, the ROS were detected through the colorimetric assay employing the nitroblue tetrazolium salt (NBT salt) and the absorbance at 650 nm was measured. The experiment was reproduced twice; the standard deviation was calculated and p-value < 0.05 were considered significant.

China's dominance in the global TiO2 market can be attributed to several factors. The country has vast reserves of titanium ore, which is the raw material used to produce TiO2
china tio2 used for paints and inks. Additionally, China has invested heavily in developing and modernizing its TiO2 production facilities, allowing the country to consistently produce high-quality TiO2 at competitive prices.

Additionally, market demand plays a significant role in determining lithopone pigment prices. Industries such as construction, automotive, and consumer goods have been experiencing fluctuations in demand, influencing the pricing dynamics. In periods of high demand, prices may increase as suppliers adjust to the market trends. Conversely, during downturns or oversupply situations, prices may decrease, providing opportunities for buyers to purchase at more favorable rates.
