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.

In 2021, the EFSA published a new opinion, stating that while titanium dioxide is not considered a concern for reproduction, development, or immunotoxicity, there is a lack of data to fully exclude a potential genotoxic effect. As a result, the European Union decided to ban its use as a food additive from May 2022, highlighting the importance of continuous monitoring and updating of safety assessments.

The construction industry, for instance, has long utilized cheap barium sulfate superfine as a filler in cement and concrete mixtures. Its high density contributes to increased weight and stability, while its inertness ensures minimal chemical reactions, enhancing the durability of structures. Moreover, in the oil and gas sector, it serves as a weighting agent in drilling fluids, preventing blowouts by adding density to the fluid and stabilizing wellbores.

The reaction liquid is filtered through plate and frame pressure to obtain lithopone in the form of a filter cake with a moisture content of no more than 45%. It is then roasted in a drying furnace to change the crystal form of lithopone, and is then pickled with sulfuric acid at a temperature of 80°C. Finally, it is washed with water, reinforced with colorants, filtered, dried and ground into powder.

Yes. According to the FDA and other regulatory agencies globally, “titanium dioxide may be safely used for coloring foods”. Titanium dioxide is safe to use, and the FDA provides strict guidance on how much can be used in food. The amount of food-grade titanium dioxide that is used is extremely small; the FDA has set a limit of 1 percent titanium dioxide for food. There is currently no indication of a health risk at this level of exposure through the diet.
