- Suppliers of titanium dioxide coatings offer a range of product grades tailored for specific uses. For example, some may be designed for maximum brightness and opacity in paints, while others may be engineered for durability and UV resistance in construction materials. The suppliers must understand the needs of different industries and provide solutions that meet those requirements.
Titanium dioxide R-5566, a rutile titanium dioxide pigment treated with zirconium and aluminum inorganic surface and organic surface, has the characteristics of high whiteness, high gloss, high achromatic power, high weather resistance, and good dispersibility.
The element titanium and the compound TiO2 are found around the world, linked to other elements such as iron, in several kinds of rock and mineral sands (including a component of some beach sands). Titanium most commonly occurs as the mineral ilmenite (a titanium-iron oxide mineral) and sometimes as the mineral rutile, a form of TiO2. These inert molecular compounds must be separated through a chemical process to create pure TiO2.
The FDA categorized titanium dioxide as “Generally Recognized as Safe,” but there are warnings about its potential dangers from other organizations.
The most common foods containing titanium dioxide are chewing gum, candies, pastries, chocolates, coffee creamers, and cake decorations (1Trusted Source, 3Trusted Source).
The FDA has not updated its general guidance on safety assessments since 2007. Within that time, there has been a significant increase in research on the confluence of toxicology, nanotechnology and human health. The EU updates its guidance regularly with new science available to offer proper safety assessments, with its most recent update published in 2021.
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).
