We even use titanium dioxide when brushing our teeth as it’s found in many toothpastes.
Manufacturers get titanium dioxide from minerals called brookite, rutile, and anatase. It's processed into a powder and refined to meet strict safety guidelines.
Titanium dioxide (TiO2) is a naturally occurring mineral that is mined from the earth, processed and refined, and added to a variety of foods, as well as other consumer products. White in color, it is used to enhance the color and sheen of certain foods and is also key for food safety applications. In its natural state it exists in different bulk crystalline forms, such as anatase and rutile, but during processing it is ground into a very fine powder.
