china titanium dioxide color

The factory's production process is a testament to precision and optimization. Raw materials, primarily ilmenite, rutile, and anatase ores, undergo a rigorous refining process that includes crushing, leaching, and solvent extraction methods. These steps ensure the purity and consistency required for high-quality pigments. Following this, gaseous chlorination converts the refined ore into titanium tetrachloride, setting the stage for the final synthesis of titanium dioxide through the oxidation of titanium tetrachloride in a heated environment.

Prof Maged Younes, Chair of EFSA’s expert Panel on Food Additives and Flavourings (FAF), said: “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”.
