anatase tio2 titanium dioxide factory

Iron oxide pigments, known for their robust stability and versatile coloring capabilities, play a pivotal role in various industries, from construction and coatings to cosmetics and plastics. These natural or synthetic compounds, derived primarily from iron ores, have become indispensable elements in the world of colorants. This article delves into the significance of iron oxide pigment suppliers and their impact on the global market.

Apart from its coloring properties, Anatase Titanium Dioxide also acts as an anti-caking agent. In powdered or granulated products, it prevents clumping by keeping the individual particles separated. This ensures that the product flows freely and maintains its quality during storage and transportation. For example, in icing sugar or powdered milk, the addition of food-grade titanium dioxide helps to keep the product free-flowing and easy to use.

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

TiO2 NPs appeared to be more toxic to nematode Caenorhabditis elegans than submicron-sized TiO2.  At a concentration of 1 mg/l, 7 nm particles affected its fertility and survival rate and were more toxic than 20 nm anatase particles. Similarly, Hu et al. showed that rutile particles (10–20 nm), at concentrations above 1 g/kg soil, can be bio-accumulated in earthworms, where they induce oxidative stress, inhibit the activity of cellulase and induce DNA and mitochondrial damage.
