In a 2020 study published in the Journal of Trace Elements in Medicine and Biology, researchers conducted an in vitro experiment to analyze the effects of TiO2 nanoparticles on a human neuroblastoma (SH-SY5Y) cell line. The scientists evaluated “reactive oxygen species (ROS) generation, apoptosis, cellular antioxidant response, endoplasmic reticulum stress and autophagy.” The results showed that exposure to the nanoparticles “induced ROS generation in a dose dependent manner, with values reaching up to 10 fold those of controls. Nrf2 nuclear localization and autophagy also increased in a dose dependent manner. Apoptosis increased by 4- to 10-fold compared to the control group, depending on the dose employed.”

When E171 isn’t combined with other ingredients and administered in water, some studies suggest that under these artificial conditions, E171 may be processed differently in the body resulting in some biological changes in experimental animals that are poorly understood.

Because of health risks, France banned titanium dioxide as a food additive in 2020. Two years later the European Union also banned titanium dioxide as a food additive.
Lyophilized vitamins@P25TiO2NPs were obtained through the described methods with excellent reproducibility and yield: over 99% of initial P25TiO2NPs were functionalized.
Of the products that include the additive in their labels, Thea Bourianne, senior manager at data consultant Label Insights, told Food Navigator USA in May 2021 that more than 11,000 products in the company's database of U.S. food and beverage products listed titanium dioxide as an ingredient. Non-chocolate candy led those numbers at 32%. Cupcakes and snack cakes made up 14%, followed by cookies at 8%, coated pretzels and trail mix at 7%, baking decorations at 6%, gum and mints at 4% and ice cream at 2%.
On the other hand, Westerhoff said, there are hundreds of studies showing no adverse effects from the substance.
One of the most common worries about titanium dioxide is that it could be a cancer-causing agent. The link between cancer and titanium dioxide traces back to a 1985 study where rats were exposed to high levels of titanium dioxide for two years, causing lung cancer. However, not all experts are convinced by this study.
That being said, titanium dioxide is particularly popular in concealers. As one of the most naturally opaque and pearly-white materials on earth, titanium dioxide has the ability to provide excellent coverage while brightening the skin, whether you’re dealing with blemishes, dark spots, acne, or dark circles under the eye.
Following six months of phasing out the additive, titanium dioxide will be completely banned in the European Union starting August 7. France had previously banned the use of titanium dioxide in food starting in January 2020.
3. Photocatalysis The photocatalytic properties of anatase make it valuable for environmental applications such as air and water purification. Manufacturers are exploring its potential in self-cleaning surfaces and photocatalytic reactors, which can degrade pollutants under UV light.
Titanium dioxide A1 adopts good oxidation process, composite inorganic coating and organic treatment, and has the characteristics of excellent particle size distribution, high brightness and high weather resistance. It is recommended for high gloss and high weather resistance coatings, inks and outdoor polymer materials.
Thanks to its rheological and optical properties, lithopone supplier 30% offers both technical and economic advantages in the substitution of titanium dioxide in different applications. Among these advantages, it has been observed that lithopone supplier 30% has algaecidal properties in paints, which gives greater protection to the coating.
5. Huntsman Corporation This American company is known for its high-quality TIO2 pigments, which are used in various applications such as paints, plastics, and cosmetics. When you choose us as your titanium dioxide supplier, you can trust that you are getting a reliable and high-quality product that meets the highest industry standards. Our commitment to excellence and customer satisfaction sets us apart as a leading manufacturer in the colorant industry.
A legal additive in the United States, titanium dioxide is used in everything from food to consumer goods and the U.S. Food and Drug Administration says regulated use of the product as a color additive in food is safe within certain restrictions.
Quality control is a vital aspect of paint pigment factories. Rigorous testing is conducted throughout the production process to ensure the pigments meet industry standards for color strength, lightfastness, and stability. This ensures that the paints made with these pigments will retain their vibrancy over time and withstand various environmental conditions.Currently, titanium dioxide as a food additive is classified as GRAS, or “generally recognized as safe.”
