Food safety experts in the European Union (EU) have recently updated their safety assessment of TiO₂ as a food additive. In Europe, TiO₂ is referred to as E171, in accordance with European labelling requirements for food additives. The EU expert panel took into account toxicity studies of TiO₂ nanoparticles, which to this point had not been considered relevant to the safety assessment of TiO₂ as a food additive.  

Does not work with hydrogen sulfide and alkaline solutions. It is easy to decompose in the presence of acid to produce hydrogen sulfide gas. It is easily oxidized in the air and deteriorates after moisture. Whiteness and hiding power are strong.

Scientists analyzed research that examined how titanium dioxide nanoparticles interact with the brain for a 2015 review published in Nanoscale Research Letters. The researchers wrote: “Once the TiO2 NPs are translocated into the central nervous system through [certain] pathways, they may accumulate in the brain regions. For their slow elimination rates, those NPs could remain in the brain zones for a long period, and the Ti contents would gradually increase with repeated exposure.” After reviewing dozens of studies, the scientists concluded: “Long-term or chronic exposure to TiO2 nanoparticles could potentially lead to the gradually increased Ti contents in the brain, which may eventually induce impairments on the neurons and glial cells and lead to CNS dysfunction as a consequence.”

Lithopone is the re-discovered white pigment with functional properties suitable for several applications.

Additionally, the growing emphasis on sustainability within the automotive industry influences the demand for environmentally friendly tire production methods. TiO2, being a non-toxic and eco-friendly compound, aligns with these sustainability goals, making it an attractive option for manufacturers looking to reduce their environmental footprint.

In cosmetics, titanium dioxide’s properties enhance coloration and can help protect skin from damaging UVA and UVB rays.

Although the evidence for general toxic effects was not conclusive, on the basis of the new data and strengthened methods our scientists could not rule out a concern for genotoxicity and consequently they could not establish a safe level for daily intake of TiO₂ as a food additive.

For that reason, the Center for Science in the Public Interest has graded titanium dioxide as a food additive that consumers should seek to “avoid.” Scientists at the nonprofit nutrition and food safety watchdog group today published a new entry for titanium dioxide in its Chemical Cuisine database of food additives.
