Above 10%, 1 kg of TiO2 should be replaced by 1.3 kg of Lithopone 30%, reducing the amount of polymer accordingly.
From studies deemed relevant, the experts found that titanium dioxide as a food additive is poorly absorbed by the gastrointestinal tract of mice and rats, with no adverse effects observed in short-term studies in rodents receiving titanium dioxide in their diets. No observed adverse effect levels (NOAELs) of 15,000 milligrams per kilogram of bodyweight (mg/kg BW) per day and 5,000 mg/kg BW per day—the highest doses tested—were established for mice and rats, respectively.
The uses and applications of Titanium Dioxide may vary according to its specification. The main forms of Titanium Dioxide are dependent on particle sizes, surface treatment, and crystalline forms.
Titanium dioxide comes in the form of a white powder and is sometimes used in cosmetics to adjust a color to a lighter shade. This is also why it can produce a white cast.
In a lawsuit filed last week, a consumer alleged that Skittles were unfit for human consumption because the rainbow candy contained a known toxin – an artificial color additive called titanium dioxide.
