  • One common method to determine sulfate as TiO2 involves gravimetric analysis. In this technique, a sample containing sulfate is treated with barium chloride, resulting in the precipitation of barium sulfate. The precipitate is then filtered, dried, and weighed. The weight of the barium sulfate precipitate correlates directly with the amount of sulfate originally present in the sample. To express this as TiO2, a conversion factor based on stoichiometry is applied. This method, while straightforward, can be time-consuming and subject to errors in filtration and drying.
  • In some studies, E171 was given to animals in drinking water without the stabilizers that keep E171 suspended in the liquid. Without stabilizers, E171 can settle and prevent the ingredient from combining with surrounding ingredients.

  • The analysis of the supernatant by UV–Vis spectrometry showed that each gram of P25TiO2NP is loaded with 0.17 g of vitamin B2, after washing them. This value is coherent with the thermogram (Fig. 1), which showed a loss of 19% of weight, attributed to the thermal decomposition of vitamin B2.

  • There has been some controversy surrounding the use of titanium dioxide in food products, as some studies have raised concerns about its potential health risks. Some studies have suggested that titanium dioxide nanoparticles may have negative effects on health when ingested in large quantities. However, the FDA has determined that titanium dioxide is safe for use in food products at the levels typically found in the diet.

  • French researchers studied how and where E171 nanoparticles enter the bloodstream, first studying the route through pigs and then in vitro with human buccal cells, for a 2023 study published in the journal Nanotoxicology. The research showed that the nanoparticles absorbed quickly through the mouth and then into the bloodstream, before damaging DNA and hindering cell regeneration.

  • One of the most significant applications of titanium dioxide is in the field of cosmetics. It is widely used as a sunscreen agent due to its ability to absorb ultraviolet radiation and protect the skin from harmful sun rays. Additionally, it is also used as a pigment in makeup products such as foundations, eye shadows, and blushes because of its excellent coverage and blending capabilities.

  • As mentioned above, these oxide NPs are harmful in part because both anatase and rutile forms are semiconductors and produce ROS. Particularly, P25 kind has band-gap energies estimated of 3.2 and 3.0 eV, equivalent to radiation wavelengths of approximately 388 and 414 nm, respectively. Irradiation at these wavelengths or below produces a separation of charge, resulting in a hole in the valence band and a free electron in the conduction band, due to the electron movement from the valence to conduction bands. These hole–electron pairs generate ROS when they interact with H2O or O2 [43,44]. It was described that they can cause an increase in ROS levels after exposure to UV-visible light [45]. The NBT assay in the studied samples showed that bare P25TiO2NPs produce a large amount of ROS, which is drastically reduced by functionalization with vitamin B2 (Fig. 5). This vitamin, also known as riboflavin, was discovered in 1872 as a yellow fluorescent pigment, [46] but its function as an essential vitamin for humans was established more than sixty years later, and its antioxidant capacity was not studied until the end of the XX century [47,48]. This antioxidant role in cells is partially explained because the glutathione reductase enzyme (GR) requires it for good functionality. This enzyme is the one in charge of the conversion of oxidized glutathione to its reduced form which acts as a powerful inner antioxidant and can quench the ROS [49,50]. The cost of this action is that the glutathione is converted to the oxidized form and needs to be recovered by the GR. Consequently, the cells need more vitamin B2. Another glutathione action is the protection against hydroperoxide. This activity is also mediated by riboflavin. Therefore, local delivery of this vitamin seems to significantly help the cells in their fight to keep the oxidative balance, once they are exposed to high levels of ROS.

  • In recent years, titanium dioxide (TiO2) has gained immense popularity across various industries due to its excellent properties, such as high opacity, brightness, and ultraviolet light absorption. As a result, the demand for titanium dioxide has increased significantly, prompting a surge in the number of manufacturers hoping to capitalize on this booming market. While quality remains a priority, cost-effectiveness has emerged as a crucial factor for consumers, leading to a growing interest in cheap titanium dioxide manufacturers.


  • From studies deemed relevant, the experts found that titanium dioxide as a food additive is poorly absorbed by the gastrointestinal tract of mice and rats, with no adverse effects observed in short-term studies in rodents receiving titanium dioxide in their diets. No observed adverse effect levels (NOAELs) of 15,000 milligrams per kilogram of bodyweight (mg/kg BW) per day and 5,000 mg/kg BW per day—the highest doses tested—were established for mice and rats, respectively.
