Titanium dioxide (TiO2) has been classified as a possible human carcinogen through inhalation since 2006. This nanomaterial was used as a food coloring and opacifying agent (E171) until it was banned for use in food as a precautionary measure in France in 2020 and by the European Union in 2022. However, it is still widely used in many everyday products (toothpaste, sunscreen, make-up, medications, plastic, paper, paint, etc.).
