The safety of food-grade titanium dioxide, or E171, lies in its ultrafine particle size. These particles are too small to be absorbed by the human body, passing through the digestive system without causing harm. Extensive research has been conducted to confirm this, with studies showing no evidence of genotoxicity or carcinogenicity. However, recent concerns about potential effects from nano-sized particles have led to ongoing evaluations However, recent concerns about potential effects from nano-sized particles have led to ongoing evaluations However, recent concerns about potential effects from nano-sized particles have led to ongoing evaluations However, recent concerns about potential effects from nano-sized particles have led to ongoing evaluationsfood safe titanium dioxide.

Drobne et al. used the terrestrial arthropod Porcellio scaber as a test organism for determining the cytotoxic effect of TiO2 NPs (anatase). The animals were exposed to TiO2 NPs of two different sizes (25 nm and 75 nm) in the concentration range 10–1000 μg TiO2/g dry food for 3 to 14 days. No adverse effects, such as mortality, body weight changes or reduced feeding, were observed. In fact, quite the opposite, an enhanced feeding rate, food absorption efficiency and increase in catalase activity were observed. The intensity of these responses appeared to be time- but not dose-dependent. It should also be noted that the concentrations tested in this study were much higher than the predicted concentration (4.8 μg/g soil) at high emission scenario of nano-sized TiO2. Using the same test organism another group showed that exposure to TiO2 NPs induced destabilization of cell membrane in the epithelium of digestive glands isolated from exposed animals. They also showed that this effect can be observed after just 30 minutes of exposure.

  • In the world of printing, the quality of ink is paramount. It not only affects the aesthetic appeal of the final product but also its durability and resistance to environmental factors. One key component that significantly influences the grade of printing ink is the use of rutile titanium dioxide, particularly the R-906 grade. This specialized pigment offers a range of benefits that make it an essential ingredient for manufacturers seeking to elevate their ink formulations.
