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”.
Wholesale titanium dioxide (rutile Cr681) finds extensive use in the paint and coatings industry. Its strong pigmentation and light-scattering abilities make it an indispensable ingredient in creating vibrant, long-lasting paints and coatings. It not only imparts whiteness but also enhances opacity, providing excellent weather resistance and durability.Titanium dioxide has been used as a bleaching and opacifying agent in porcelain enamels, giving them brightness, hardness, and acid resistance. In modern times it is used in cosmetics, such as in skin care products and sunscreen lotions, with claims that titanium dioxide protects the skin from ultraviolet radiation because of its property to absorb ultraviolet light.
In conclusion, titanium dioxide is a versatile and widely used chemical compound with a range of applications in various industries. Its excellent whiteness, opacity, chemical stability, and cost-effectiveness make it an attractive option for manufacturers looking for high-quality, durable products. As demand for titanium dioxide continues to grow, it is likely that we will see even more innovative uses for this versatile compound in the future.
