Procurement of TIO2 involves a complex process, starting from sourcing the raw materials, primarily ilmenite, rutile, or titanium-bearing slag, to negotiating contracts with suppliers. Manufacturers often prioritize suppliers that can guarantee consistent quality, competitive pricing, and reliable delivery schedules. This necessitates strong relationships and strategic partnerships with mining companies, which are typically located in regions rich in titanium resources, such as Australia, South Africa, and Canada.

Titanium dioxide is a naturally-occurring mineral found in the earth’s crust. Because of its white color, opaqueness, and ability to refract light, the ingredient is often used as a pigment, brightener, and opacifier, which is an ingredient that makes a formulation more opaque. Titanium dioxide is also a UV filter and so is an effective active ingredient in sunscreens. It’s often used in cosmetic loose and pressed powders, especially “mineral powder” cosmetics, in addition to other cosmetics, lotions, toothpaste, and soap.

The manufacturing process of lithopone involves several steps, including sulfide precipitation, grinding, classification, and packaging. During the sulfide precipitation stage, zinc sulfide and barium sulfate are reacted in an aqueous solution under controlled conditions to form a precipitate of lithopone. The precipitate is then washed, dried, and ground to the desired particle size distribution. Finally, the ground pigment is classified to remove any oversized or undersized particles and packaged for storage and transportation.
