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.

Lithopone was discovered in the 1870s by DuPont. It was manufactured by Krebs Pigments and Chemical Company and other companies.[2] The material came in different seals, which varied in the content of zinc sulfide. Gold seal and Bronze seals contain 40-50% zinc sulfide, offering more hiding power and strength.[3] Although its popularity peaked around 1920, approximately 223,352 tons were produced in 1990. It is mainly used in paints, putty, and in plastics.[1]

Maintaining consistency and quality during scale-up is one of the most challenging aspects of nano-TiO2 production. The factory must adhere to stringent quality control measures, using advanced analytical techniques like X-ray diffraction (XRD) and transmission electron microscopy (TEM) to ensure the purity and uniformity of the nanoparticles. Additionally, environmental safety and health considerations are paramount, given the potential risks associated with nanomaterials.
