Prof. Maged Younes, Chair of EFSA’s expert Panel on Food Additives and Flavourings (FAF), wrote of the decision: “Taking into account all available scientific studies and data, the Panel concluded that titanium dioxide can no longer be considered safe as a food additive. A critical element in reaching this conclusion is that we could not exclude genotoxicity concerns after consumption of titanium dioxide particles. After oral ingestion, the absorption of titanium dioxide particles is low, however they can accumulate in the body.”

“Unlike some other chemicals used in food, titanium dioxide has no nutritive, preservative, or food safety function—its use is purely cosmetic,” said CSPI principal scientist for additives and supplements, Thomas Galligan. “The prospect of titanium dioxide nanoparticles damaging DNA is concerning enough for us to recommend consumers avoid foods that have it.” 

Caiqing Technology is a specialized production of titanium dioxide enterprises, the company will titanium dioxide this product as the company's core industry. Caiqing technology with the regional sulfuric acid scale advantage, with titanium ore as raw material, actively introduce the top technology at home and abroad, the use of mature sulfuric acid titanium dioxide production process to produce high quality rutile titanium dioxide products and anatase titanium dioxide products, its production process, equipment and automation control are in the domestic leading level. Caiqing technology will pay attention to the technology of titanium dioxide research and development, to provide high-quality titanium dioxide for the paint industry to contribute their own strength. Thank the China Paint Association visit, we must live up to the trust of Caiqing technology titanium dioxide brand! Thanks!

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.
