titanium dioxide used in medicine factories

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.

Firstly, TiO2 is commonly used as a white pigment in plastic products. Its high refractive index and ability to scatter light across the visible spectrum provide excellent opacity and brightness to plastic materials. This makes it an essential component in producing white or light-colored plastics, such as packaging materials, household items, and toys. The addition of TiO2 not only enhances the aesthetic appeal of these products but also improves their overall quality by increasing their durability and resistance to UV radiation.
