Since 2020, the European Commission has adopted a harmonized classification for titanium dioxide: suspected carcinogen (category 2) by inhalation for certain powder forms. This classification has since been contested by industrialists.
This classification aims to protect the health of European citizens and workers who handle this substance.
Chronology to understand the debate:
Based on studies provided by ANSES, ECHA’s Committee for Risk Assessment (RAC) ruled that titanium dioxide was suspected of being carcinogenic to humans, by inhalation, in the form of a powder containing 1% or more particles with a diameter of 10 μm or less.
According to expert opinion: “The carcinogenicity of titanium dioxide to the lungs is associated with inhalation of respirable titanium dioxide particles, retention and low solubility of particles in the lungs. In order to avoid an unjustified classification of non-hazardous forms of that substance, specific notes should be added concerning the classification and labelling of the substance and mixtures containing it. (Regulation 2020/217) Consequently, the classification of titanium dioxide may vary depending on its bioaccessibility.
The Tribunal relied on these same studies to have the regulation annulled by carrying their own assessments and interpretations of the scientific data. In so doing, France considers that the General Court has exceeded the limits of its judicial review and is appealing the case.
This appeal suspends the judgment of the General Court and the harmonized classification of Regulation 2020/217 will therefore continue to apply until the outcome of this new procedure.
