By reducing processed foods in your diet, you can reduce the likelihood of not only eating titanium dioxide but eating other chemicals of concern, Faber said, noting that consumers can also call their elected representatives urging them to support increased food safety legislation and take action with organization alliances like Toxic Free Food FDA.

This precipitate is not suitable for a pigment until it is filtered, dried, crushed, heated to a high temperature, and quenched in cold water. The second heating in a muffle furnace at 725 C produces crystals of the right optical size.

There are many uses of titanium dioxide that we don't know about because they were made exempt from being on the package in 1977, said Faber, who added that nothing much has changed since – other than the FDA approving some other uses of the color additive, such as expanding the use of mica-based pearlescent pigments (prepared from titanium dioxide) as color additives in distilled spirits over recent years.
