Titanium dioxide factories are state-of-the-art establishments, equipped with cutting-edge technology and stringent quality control measures. These facilities specialize in the extraction and refinement of titanium dioxide from raw materials like ilmenite, rutile, or anatase. The process, known as the sulfate or chloride route, involves several stages including digestion, precipitation, calcination, and finally, milling to achieve the desired particle size and optical properties.

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.

Over the last several years, nanoparticles have come under scrutiny for adverse health effects. Nanoparticles are ultrafine particles between 1 to 100 nanometers in diameter. (To put this in perspective, the average human hair is around 80,000 nanometers thick.) Because of their size, which can be engineered and manipulated at the atomic or molecular level, nanoparticles exhibit unique physical, chemical, and biological properties. Titanium dioxide is one of the most commonly produced nanoparticles in the world.
