Titanium dioxide (TiO2) is a naturally occurring mineral that is mined from the earth, processed and refined, and added to a variety of foods, as well as other consumer products. White in color, it is used to enhance the color and sheen of certain foods and is also key for food safety applications. In its natural state it exists in different bulk crystalline forms, such as anatase and rutile, but during processing it is ground into a very fine powder.
Not everyone agrees, though. The European Commission banned titanium dioxide as a food additive in the European Union in 2022.
tio2 cosmetics manufacturers. Non-Irritating TiO2 is generally considered non-irritating to the skin, making it suitable for use in a wide range of cosmetic products.Fig. 4. Hemolysis (%) values of samples, A: 0.2 mg/mL P25TiO2NPs; B: 0.02 mg/mL P25TiO2NPs; C: 0.2 mg/mL VitaminB2@P25TiO2NPs; D: 0.02 mg/mL VitaminB2@P25TiO2NPs after 3 h of irradiation (red) and 6 h (blue). SD <5 for all samples and p <0.05 between C-D and A-B.
Moreover, a 2019 study noted that food-grade titanium dioxide was larger and not nanoparticles. Hence, the authors concluded that any titanium dioxide in food is absorbed poorly, posing no risk to human health (3Trusted Source).
2. Improved Aesthetics Titanium dioxide serves as a highly effective white pigment, providing tires with a bright and appealing finish. While the traditional black color of tires is often associated with carbon black, incorporating TiO2 can offer design flexibility and aesthetic value without compromising performance.
