- Good whiteness titanium dioxide rutile is a critical component for coating factories due to its exceptional optical properties. The term good whiteness refers to the pigment's ability to reflect a broad spectrum of visible light, resulting in a bright, clean appearance. This characteristic is particularly important in applications where a uniform and consistent color is desired, such as in paints, plastics, and paper manufacturing.

Following the EU’s ban on E171, the FDA told the Guardian that, based on current evidence, titanium dioxide as a food additive is safe. “The available safety studies do not demonstrate safety concerns connected to the use of titanium dioxide as a color additive.”
- In the cosmetics industry, ATDNs are used as UV filters to protect skin from harmful UV radiation. Their small size allows them to be easily incorporated into various cosmetic products, providing effective sun protection without the typical side effects associated with chemical sunscreens. In addition, ATDNs also exhibit excellent photostability, ensuring long-lasting protection against UV rays.

- To address this environmental challenge, Chinese companies have been investing in research and development to improve the efficiency of TiO2 production methods and reduce their carbon footprint. For instance, the adoption of advanced technologies like the sulfate process, which has lower emissions compared to the chloride process, is being encouraged. Additionally, there is a growing focus on utilizing renewable energy sources to power these manufacturing plants.

Some consumer advocacy groups and health agencies — particularly, those at the Environmental Working Group — have been pushing federal officers at the Food and Drug Administration (FDA) to reconsider their existing rules on the additive, which is commonly found in processed snacks and sweets.
This constant high rate of ROS production leads rapidly to extreme macromolecular oxidation, here it is observed in the AOPP and MDA detected after 3 h in samples treated with bare P25TiO2NPs (Fig. 6, Fig. 7). Macromolecular oxidation includes, among others, both protein and lipid oxidation. The ROS causes protein oxidation by direct reaction or indirect reactions with secondary by-products of oxidative stress. Protein fragmentation or cross-linkages could be produced after the oxidation of amino acid side chains and protein backbones. These and later dityrosine-containing protein products formed during excessive production of oxidants are known as advanced oxidation protein products (AOPP). They absorb at 340 nm and are used to estimate the damage to structural cell amino acids. Lipid oxidation is detected by the conjugation of oxidized polyunsaturated lipids with thiobarbituric acid, forming a molecule that absorbs light at 532 nm. Polyunsaturated lipids are oxidized as a result of a free-radical-mediated chain of reactions. The most exposed targets are usually membrane lipids. The macromolecular damage could represent a deadly danger if it is too extensive, and this might be the case. Moreover, it could be observed that cellular damage continues further and becomes irrevocable after 6 h and MDA could not be detected. This may be due to the fact that the lipids were completely degraded and cells were no longer viable. Lipids from the cell membrane are the most prone to oxidation. In fact, lipid peroxidation biomarkers are used to screen the oxidative body balance [51]. At the same time, AOPP values are up to 30 times higher for bare nanoparticles in comparison to the functionalized ones.
Calcium carbonate (CaCO3) and titanium dioxide (TiO2) are two widely used industrial materials with various applications. In this article, we will discuss the importance of CaCO3 and TiO2 in manufacturing processes and their impact on the global economy.
Importance in Factory Settings
When used in food specifically, titanium dioxide is known as an additive called E171 and can be found in products like candy, chocolate, coffee creamer, cake decorations, chewing gum and even vitamin supplements. E171 is often used as coloring additive in foods, to lend the processed item a natural whiteness and opacity — such as in Skittles candy, where it's used as a white base to help give the candies their signature bright, colorful hue.
pH-value
Following a request for assessment in 2020 by the EU, the European Food Safety Authority (EFSA) assessed E171, particularly for its genotoxicity. In 2022, the agency deemed the food additive no longer safe for use.
