Titanium dioxide occurs naturally in titanium ores such as titanium ore and rutile. Its molecular structure gives it high brightness and permeability, but it must first be chemically extracted and purified. More than 60 years ago, DuPont invented the chlorinated titanium dioxide production process, which has become the world's preferred technology because it can manufacture high-quality pigment products while reducing environmental emissions and Chemicalbook energy consumption compared to the old sulfuric acid process. Titanium dioxide (or TiO2) is the most widely used white pigment in industry, used in construction, industrial and automotive coatings; Plastics for furniture, electrical appliances, plastic tapes and plastic boxes; Paper for high-end magazines, brochures and films, as well as specialty products such as inks, rubber, leather and elastomers.

Bleacher. Titanium dioxide can be used as all food white pigment for paint, ink, plastic, rubber, paper, chemical fiber and other industries; Used in welding electrodes, refining titanium and manufacturing titanium dioxide, titanium dioxide (nanoscale), widely used in functional ceramics, catalysts, cosmetics and photosensitive materials and other white inorganic pigments. It is one of the strongest coloring power in white pigments, with excellent hiding power and coloring fastness, suitable for chemicalbook for opaque white products. Rutile type is especially suitable for plastic products used outdoors, which can give the products good light stability. Anatase type is mainly used for indoor use products, but slightly blue light, high whiteness, large hiding power, strong coloring power and good dispersion. Titanium dioxide is widely used as pigments for paint, paper, rubber, plastic, enamel, glass, cosmetics, ink, watercolor and oil paint, and can also be used for oily titanium dioxide to attach an inorganic oxide film to the surface of titanium dioxide, so that its surface properties change from hydrophilic to strongly hydrophobic. A special mixing and dispersion technology is used with surfactants to prepare a uniform and stable oily system dispersion. Suitable for general cosmetic oil-based dispersants, Chemicalbook can also be used for high-grade environmentally friendly oil-based paints. It is also suitable for water-based micron cosmetics in high-end food, titanium dioxide is an excellent dispersant of hydrophilic type in cosmetics, with good whiteness, strong hiding power and good dispersion. Its disadvantages are not suitable for cosmetics with salt containment. It is also suitable for high-end food.
