- R960 is particularly well-suited for use in TiO2 manufacturing processes due to its ability to enhance the performance of catalysts used in the production of TiO2. These catalysts play a crucial role in the oxidation of titanium tetrachloride (TiCl4) to form TiO2 particles These catalysts play a crucial role in the oxidation of titanium tetrachloride (TiCl4) to form TiO2 particles

r960 tio2 factories. By incorporating R960 into these catalysts, manufacturers can achieve higher reaction rates and yields, resulting in significant cost savings and improved product quality.
- After the chemical treatments are complete, the pigment is dried and milled to ensure a uniform particle size and distribution. The final product is then carefully packaged and stored in controlled conditions to maintain its quality and stability.
- Titanium dioxide, often abbreviated as TiO2, is a compound with an extraordinary place in the wholesale pigment market. This versatile substance boasts a wide range of applications, from brightening our days to protecting the environment.
Genotoxicity refers to the ability of a chemical substance to damage DNA , the genetic material of cells. As genotoxicity may lead to carcinogenic effects, it is essential to assess the potential genotoxic effect of a substance to conclude on its safety.
Risk managers at the European Commission and in EU Member States have been informed of EFSA’s conclusions and will consider appropriate action to take to ensure consumers’ protection.
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.


Over the last several years, nanoparticles have come under scrutiny for adverse health effects. Nanoparticles are ultrafine particles between 1 to 100 nanometers in diameter. (To put this in perspective, the average human hair is around 80,000 nanometers thick.) Because of their size, which can be engineered and manipulated at the atomic or molecular level, nanoparticles exhibit unique physical, chemical, and biological properties. Titanium dioxide is one of the most commonly produced nanoparticles in the world.
Because of their small size, nanoparticles may have unique physical and chemical properties. These properties may cause them to interact with living systems differently than larger materials with the same chemical composition (also known as bulk materials).


People eating lots of candy should be more worried about the sugar and how it can cause high blood pressure and obesity, says Westerhoff.
The most significant uncertainty identified by the EU experts was the concern that TiO2 particles may have genotoxic effects. Genotoxicity refers to the ability of a chemical to directly damage genetic material within a cell (DNA), which may lead to cancer in certain situations. Although the experts did not conclude that TiO2 particles in E171 are genotoxic, they could not rule out the concern that they might be.
The European Food Safety Authority (EFSA) has concluded that titanium oxide should not be considered safe as a food additive, due to uncertainties about possible inflammation and neurotoxicity (9Trusted Source).
Titanium dioxide is often used as a UV absorber and pigment in cosmetic products, such as foundations, lipsticks, creams, sunscreens and other skin care products. It helps protect the skin from the harmful effects of UV rays by blocking them, while providing a brightening effect.
The risks associated with titanium dioxide exposure depend on a variety of factors, including the form of the mineral, the route of exposure (such as being inhaled or consumed), and the duration and intensity of exposure.
