Nanotoxicology “focuses on determining the adverse effects of nanomaterials on human health and the environment.”

It is a national high-tech enterprise, a national top 500 chemical enterprise, and the largest titanium dioxide exporter in China. The main products are TiO2, zirconium products, sulfuric acid and sulfate. Among them, titanium dioxide has reached 120,000 tons, and its export volume has ranked first in the country for three consecutive years. The annual production capacity of the main titanium dioxide is 600,000 tons, ranking first in Asia and fourth in the world.

Aside from its use in paints, coatings, plastics, and paper, TiO2 is also utilized in a variety of other industrial applications. It is commonly found in cosmetics, sunscreens, and food products, where it serves as a safe and effective whitening agent. TiO2 is also used in the production of ceramics, glass, and textiles, where it enhances their appearance, durability, and resistance to fading.

Other research suggests that E171 could cause harm; however, those research processes did not consider how people are typically exposed to E171. Research that adds E171 to drinking water, utilizes direct injections, or gives research animals E171 through a feeding apparatus is not replicating typical human exposure. 

Zinc oxide. Zinc oxide is a popular cross-linking agent for rubber and for various resins. It is essential in the formulation of solvent-borne polychloroprene adhesives. Furthermore, zinc oxide is a good UV stabilizer, has biocidal activity and has a relatively high refractive index (2.0) which makes it an efficient white pigment. Some typical properties are: density 5.6 g/cm³; particle size 0.036-3 μm; oil absorption 10–20 g/100 g; specific surface area 10–45 m²/g. Zinc oxide is produced by reaction of the metal in the vapour state with oxygen. Zinc oxide is nonporous and is quite pure. Thus, the high surface area of some grades is due to the small particle size of zinc oxide. Some grades, especially for use in the rubber industry, are surface modified by deposition of 0.2-0.4% of stearic acid, propionic acid, or light oil [47].

Animal studies show exposure to titanium dioxide is linked to immunotoxicity, inflammation and neurotoxicity.
