Titanium dioxide, also called titania, is an odorless white powder and naturally occurring mineral that is widely used as a pigment for its brightness and whitening effects on a variety of materials, such as paint, plastic, paper, cosmetics, sunscreens, toothpastes and foods.
It’s produced through the sulfate or chloride process, which both involve treating titanium ore with sulfuric or hydrochloric acid to produce titanium sulfate or titanium chloride. These materials are then further processed to remove impurities and produce titanium dioxide in its final form.
Food-grade titanium dioxide differs from what’s added to plastics and paints to enhance whiteness. However, there have been concerns about the environmental impact of titanium dioxide production and the potential health risks from exposure to its particles.
Although food-grade titanium dioxide must be 99 percent pure, there’s still a risk of it containing potential contaminants, such as mercury, lead and arsenic. Additionally, inhaling the mineral over time can possibly cause it to build up in your body, leading to adverse effects.
Uses
In an era where health and safety standards are paramount, the use of non-hazardous additives is crucial In an era where health and safety standards are paramount, the use of non-hazardous additives is cruciallithopone for rubber. Lithopone is lead-free, making it a safe alternative to traditional lead-based pigments that pose environmental and health risks. This feature ensures that rubber products containing lithopone are compliant with stringent international regulations and industry standards.Porcelain White, 32 per cent sulphide, 68 per cent barium sulphate.
