It turns into light gray after being exposed to ultraviolet rays in sunlight for 6 to 7 hours, but it will return to its original color when placed in a dark place. It is easy to oxidize in the air and then agglomerate and deteriorate when exposed to moisture.
In 2021, the European Food Safety Authority concluded that titanium dioxide is no longer safe in foods due to the same concerns over nanoparticles. As a result, titanium dioxide is now banned as a food additive in the EU. Although studies have shown that the absorption of ingested titanium dioxide is low, evidence suggests that titanium dioxide nanoparticles can accumulate in the body over time. Health Canada deemed it safe in 2022 but noted concerns. Unlike their European counterparts, Canadian officials did not consider studies performed with titanium dioxide nanoparticles alone.
Quality control is paramount in the manufacture of zinc barium sulfateFig. 6. AOPP measured on samples of MSSA with: A) 0.2 mg/mL P25TiO2NPs; B) 0.02 mg/mL P25TiO2NPs; C) 0.2 mg/mL VitaminB2@P25TiO2NPs; D) 0.02 mg/mL VitaminB2@P25TiO2NPs after 3 h of irradiation (red) and 6 h (blue). SD <1 (error bars too small to be seen) and p < 0.05 between C-D and A-B.
In the cosmetics industry, titanium dioxide is used as a sunscreen agent to protect skin from harmful UV rays. It is also used in makeup products such as foundations and powders to provide a natural-looking coverage and a radiant finish. The micronized form of titanium dioxide is particularly effective at absorbing UV light, making it a popular choice among consumers who are concerned about sun protection.No. The titanium dioxide we use in our toothpastes has been proven safe by health experts around the world. It is used in our toothpastes as a white colourant, in a non-nano form as defined by European regulations. It is an approved colourant in cosmetics, and we comply with all the regulations applicable to it.
One of the primary benefits of using titanium dioxide in plastic manufacturing is its ability to enhance the appearance of the final product. The pigment provides excellent opacity, which means that it can effectively hide any imperfections or discolorations on the surface of the plastic material. This results in a more aesthetically pleasing product that appeals to consumers. Some of the leading players in the rutile market factory industry include Rio Tinto, Iluka Resources, Tronox, and Cristal Global. These companies have extensive experience in the extraction, processing, and marketing of rutile, and they continue to invest in research and development to improve their processes and products.

In Home Care products, the presence of titanium dioxide is declared in line with local regulations, which can vary across the world. In some countries, titanium dioxide is not declared if only a small amount of the ingredient is used. In other countries titanium dioxide is grouped under ‘colourants’ in the ingredients list. In Europe, regulation requires all home care ingredients to be disclosed through a supporting website. You can find our product ingredient information page by visiting ‘
In conclusion, China's titanium dioxide story is a blend of economic prowess, vast resources, and evolving environmental considerations. As the chemical formula TiO2 continues to play a pivotal role in various industries, China's position in this market underscores the interconnectedness of global economies and the significance of sustainable industrial practices. The future of the TiO2 industry will likely be shaped by China's ability to balance production efficiency with environmental sustainability, setting a precedent for the rest of the world. Despite these advancements, the pigment lithopone industry faced competition from alternative pigments like titanium dioxide, which offered similar properties at a lower cost. This competition forced many factories to adapt or risk closure This competition forced many factories to adapt or risk closureCSPI’s Chemical Cuisine is the web’s definitive rating of the chemicals used to preserve foods and affect their taste, texture, or appearance. Besides titanium dioxide, the group recommends avoiding artificial sweeteners like aspartame, acesulfame potassium, and sucralose, as well as synthetic food dyes like Yellow 5 and Red 3. CSPI and others have recently asked the Food and Drug Administration to ban the latter dye in foods and ingested drugs because the FDA has already determined that it is a carcinogen unsafe for use in cosmetics.
