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].

In January 2022, the average price of domestic titanium dioxide in local Chinese marketplaces was 20,735 RMB/MT. Traders were more careful in purchasing goods and downstream industries purchased things on demand. As a result, the overall market demand for titanium dioxide was general.

In conclusion, titanium IV oxide is a versatile compound that is used in a wide range of industries. From sunscreen to paints to food coloring to pharmaceuticals, titanium dioxide plays a vital role in many products. Its unique properties, such as UV protection, brightness, and stability, make it an essential ingredient in various applications. As technology continues to advance, titanium IV oxide will likely continue to play a key role in the manufacturing of innovative products.

For that reason, the Center for Science in the Public Interest has graded titanium dioxide as a food additive that consumers should seek to “avoid.” Scientists at the nonprofit nutrition and food safety watchdog group today published a new entry for titanium dioxide in its Chemical Cuisine database of food additives.
