EFSA's evaluation is related to the risks of TiO2 used as a food additive, not to other uses.
Other food manufacturers use titanium dioxide to absorb water and keep moisture from clumping or degrading, Paul Westerhoff, PhD, an environmental engineer at Arizona State University who researches the biological and cellular effects of titanium dioxide, told Health.
A review published in 2022 in the journal NanoImpact evaluated the latest research related to genotoxic effects of titanium dioxide through in vivo studies and in vitro cell tests. Researchers summarized the results by stating TiO2 nanoparticles “could induce genotoxicity prior to cytotoxicity,” and “are likely to be genotoxic to humans.”

zinc barium sulphate factories. These facilities continuously strive to improve the purity and efficiency of their processes, adhering to strict environmental and safety standards. They invest in advanced technologies to minimize waste and ensure sustainable production methods.Scrap zinc or concentrated zinc ores are dissolved in sulfuric acid, the solution is purified and the two solutions are reacted. A heavy mixed precipitate results that is 28 to 30% zinc sulfide and 72 to 70% barium sulfate.
Lithopone is a white pigment (PW5) co-precipitated from solutions of zinc and barium salts according to the following reaction:
- Needle Roller Bearings: Needle roller bearings are commonly used in applications where space is limited, and high radial load-carrying capacity is essential. They are often found in automotive, aerospace, and industrial applications where compact and lightweight bearing solutions are required.
The raceways, both inner and outer, are precisely machined to ensure a balanced distribution of forces, allowing the bearing to handle radial and some degree of axial loads effectively The raceways, both inner and outer, are precisely machined to ensure a balanced distribution of forces, allowing the bearing to handle radial and some degree of axial loads effectively606zz bearing dimensions.
This ensures not only a longer service life but also consistent performance under extreme conditions, such as elevated temperatures or aggressive environments This ensures not only a longer service life but also consistent performance under extreme conditions, such as elevated temperatures or aggressive environments22216 bearing.
