Titanium dioxide has many purposes in both food and product development.

Studies have been carried out with both emulsion paints and powder paints, both with clear results on how the use of lithopone supplier 30% reduces the appearance of algae in the paint once it has been applied (see photos).

Titanium is a metal element found naturally in the environment. When it's exposed to oxygen in the air, it forms titanium oxides that are contained in many minerals, sands, soils, and dusts.

Calcium carbonate is a naturally occurring mineral that is found in rocks and minerals such as calcite, aragonite, and limestone. It is commonly used in industries such as paint, paper, plastics, and rubber as a filler and pigment. The manufacturing process of calcium carbonate involves extracting the mineral from quarries or mines, crushing and grinding it into a fine powder, and then purifying it through various chemical processes.

All food businesses currently using titanium dioxide as a food additive have a legal responsibility to comply with the requirements of Regulation (EU) 2022/63, banning the use of titanium dioxide. The FSAI encourages food businesses to source suitable alternatives to titanium dioxide and start the process of reformulation now to ensure compliance in advance of the ban coming into force on 7 August 2022.

When it comes to sourcing titanium dioxide, it is essential to understand the various processes involved in its production. The two primary production methods are the sulfate process and the chloride process. The sulfate process tends to be more cost-effective in certain contexts, but it also generates a substantial amount of waste, putting pressure on manufacturers to invest in waste treatment technologies. On the other hand, the chloride process is known for its superior quality and lower environmental impact, albeit at a higher production cost.

When examining a lithopone pigment pricelist, one might notice that prices can vary significantly between different grades of lithopone. Generally, there are two main types Lithopone 28 and Lithopone 60, with the numbers denoting the percentage of zinc sulfide content. Lithopone 28, with a lower zinc sulfide content, is often more affordable compared to Lithopone 60, which offers superior whiteness and opacity. The choice between these grades depends largely on the specific requirements of the end application.

With the rise of nanotechnology, research in recent years has also shown the dangers of titanium dioxide (TiO2) nanoparticles, and their genotoxicity, which refers to a chemical agent’s ability to harm or damage DNA in cells, thus potentially causing cancer.
