A review published in 2022 in the journal NanoImpact evaluated the latest research related to genotoxic effects of titanium dioxide through in vivo studies and in vitro cell tests. Researchers summarized the results by stating TiO2 nanoparticles “could induce genotoxicity prior to cytotoxicity,” and “are likely to be genotoxic to humans.”

The conjugation of vitamin C to the P25TiO2NPs was confirmed by UV-visible spectroscopy of lyophilized vitaminC@P25TiO2NPs suspensions. The typical absorbance peak of ascorbic acid at 265 nm was found. However, no further characterization was done because they did not show the expected protective effect against the photo-induced cell damage (Fig. 3).
Although barium sulfate is almost completely inert, zinc sulfide degrades upon exposure to UV light, leading to darkening of the pigment. The severity of this UV reaction is dependent on a combination of two factors; how much zinc sulfide makes up the pigments formulation, and its total accumulated UV exposure. Depending on these factors the pigment itself can vary in shade over time, ranging from pure white all the way to grey or even black. To suppress this effect, a dopant may be used, such as a small amount of cobalt salts, which would be added to the formulation. This process creates cobalt-doped zinc sulfide. The cobalt salts help to stabilize zinc sulfide so it will not have as severe a reaction to UV exposure.
In the realm of plastic manufacturing, titanium dioxide stands as a cornerstone additive, enhancing both the aesthetic appeal and functional properties of various plastic products. This versatile compound, known chemically as TiO2, is a white pigment widely used in industries ranging from paints and coatings to food coloring and sunscreens. However, its role in plastic factories is particularly noteworthy due to its unique attributes that contribute significantly to the production process.While this ruling from the EU General Court doesn’t immediately change the regulations surrounding titanium dioxide, nor does it change the ban that went into place in 2022, it does put the ingredient back in the spotlight.
In the coming months, we will see how the ruling impacts the regulations around titanium dioxide (E171), and we’ll see if the European Food Safety Authority (EFSA) will take another look at the body of scientific evidence used to justify the current ban on E171 in foods and pharmaceuticals.
European food safety regulators have since labeled titanium dioxide as no longer safe for human consumption, due to its potential toxicity.
The Role of R-906 Rutile Titanium Dioxide in Enhancing Printing Ink Grade In conclusion, the journey of TiO2 industry factories from high-volume producers to eco-friendly, technologically advanced centers of innovation reflects broader industrial transitions toward efficiency, sustainability, and global competitiveness. As these facilities continue to evolve, they stand at the forefront of material science, contributing not just to economic growth but also to a more responsible and interconnected world. One of the key characteristics of titanium dioxide rutile is its particle size, shape, and crystal structure. These factors directly impact the pigment's performance and application in various products. This is why manufacturers invest in advanced technology and processes to produce titanium dioxide rutile with the right characteristics that meet industry standards and customer requirements.However, since it’s photosensitive — meaning it can stimulate free radical production — it’s usually coated in silica or alumina to prevent potential cell damage without reducing its UV-protective properties (7Trusted Source).

The Process of Gravimetric Determination of TiO2
TiO2 powder is also widely used in the cosmetics industry, where it is used as a whitening agent in skincare products, sunscreen, and makeup. TiO2 powder suppliers work closely with cosmetic manufacturers to ensure that they have a reliable and high-quality supply of TiO2 powder to meet the demands of their consumers.
