ANSES reaffirms the need to limit oral exposure to nano titanium dioxide

The National Health Security Agency (ANSES) has published today a so-called “nano-specific” risk assessment of titanium dioxide used as a food additive (E171). This is the third part of the approach initiated by ANSES in 2020 on nanomaterials in products intended for food and the first application of the risk assessment methodology specific to nanomaterials used as food additives established by ANSES in 2021. 

Dans cet review, the agency relates the lack of toxicological data available to carry out a complete assessment of the additive E171. A very regrettable state of affairs because it prevented the agency from completing the risk assessment of the additive E171. “The experts have identified all the data that will have to be produced on this nanomaterial, they concern general toxicity, genotoxicity, carcinogenicity, neurotoxicity or even toxicity for reproduction and development”, explains Bruno Teste, coordinator of the expertise and scientific project manager in the food risk assessment unit at ANSES.

ANSES concludes by reaffirming its recommendation to limit the uses and exposure of workers and consumers to nanomaterials, "by promoting the use of safe products, devoid of manufactured nanomaterials, and by limiting these uses to those ultimately considered duly justified and subject to a documented demonstration of the acceptability of the risk”.

These conclusions raise questions: despite theprohibition of the additive E171 in food entered into force in France since January 2020 then in Europe since August 2022, titanium dioxide nanoparticles are still authorized and used in many everyday products, especially in cosmetic products, hygiene or in medicines.
