- Barium sulfate, also known as barite, is a white crystalline mineral that is commonly used in various industries such as oil and gas drilling, paints, plastics, and pharmaceuticals. The price of barium sulfate can vary depending on the manufacturer and the quality of the product.
Neutral White, 26 per cent zinc sulphide, 66 per cent barium sulphate, 5 per cent infusorial earth, 3 per cent whiting.
Based on this opinion, the European Commission and the Member States agreed to remove all uses of titanium dioxide as an additive in food. In January 2022, a Regulation withdrawing the authorisation to use titanium dioxide as a food additive in food products was adopted i.e. Commission Regulation (EU) 2022/63.
Calcium carbonate and titanium dioxide are two important minerals that are widely used in various industries. While they share some similarities, they also have distinct differences when it comes to their manufacturing processes and applications.
1. Properties: white powder, a mixture of zinc sulfide and barium sulfate.
If you're curious about whether something you’re eating contains titanium dioxide, you can check the ingredients list. But know that the FDA doesn’t require food makers to use its chemical name on an ingredients list. Instead, it could be listed as:


Lithopone is produced by coprecipitation of barium sulfate and zinc sulfide. Most commonly coprecipitation is effected by combining equimolar amounts of zinc sulfate and barium sulfide:


Manufacturers use titanium dioxide in some packaging to protect food from exposure to sunlight. Lab studies show it may also help stop bacteria from growing, and break down a gas that makes many fruits and vegetables ripen faster. That can keep products fresher and give them a longer shelf life.

In 2016, the European Food Safety Authority, or EFSA, assessed titanium dioxide and determined that the evidence available at the time didn’t conclusively point to any health problems for consumers.


6. What happens next?

Often used as a glaze for ceramics, titanium dioxide provides a bright, glossy finish and improves the durability and stain resistance of ceramic products.
A few non-dietary studies have reported adverse effects in the gastrointestinal tract of laboratory animals given food-grade TiO2. However, these same effects were not seen when the same or higher doses of food-grade TiO2 were administered in the animals' diet. Dietary studies best reflect how humans are exposed to TiO2 from food. Thus, the Food Directorate placed the most emphasis on the results of these studies in the state of the science report.
Does It Cause Cancer?
Titanium dioxide (E 171) is authorised as a food additive in the EU according to Annex II of Regulation (EC) No 1333/2008.
