The calcined product obtained by the ordinary zinc-barium white preparation method is beaten into a slurry, which is then surface-treated with sodium silicate, aluminum sulfate or sodium aluminate and surfactant, and then filtered, washed, dried and pulverized. Can.

Another common use of titanium IV oxide is in food coloring. Titanium dioxide is a FDA-approved food additive that is used to enhance the color of various food products. It is commonly used in candies, pastries, and dairy products to create vibrant colors. Titanium dioxide is a safe food additive that is used in small quantities to enhance the visual appeal of food products.

Studies suggest that people are more likely to buy and eat foods that are brighter or more vibrant in color. And titanium dioxide is one way to make that happen. You can find it in food products like candy, coffee creamer, baking and cake decorations, and white sauces.

It doesn’t take much to imagine what they must be doing to our poor skin each day as we layer on our sunscreen, foundation, concealers, eyeshadows & lip sticks which all contain large doses of titanium dioxide.

However, it can cause photosensitivity, which is why it’s often combined with silica or alumina to prevent cell damage.

Food additive or carcinogen? The growing list of chemicals banned in EU but used in US, by Mikaela Conley, The Guardian, June 23, 2022

The safety of the food additive E 171 was re-evaluated by the EFSA ANS Panel in 2016 in the frame of Regulation (EU) No 257/2010, as part of the re-evaluation programme for food additives authorised in the EU before 20 January 2009.  

Titanium dioxide has been used as a bleaching and opacifying agent in porcelain enamels, giving them brightness, hardness, and acid resistance. In modern times it is used in cosmetics, such as in skin care products and sunscreen lotions, with claims that titanium dioxide protects the skin from ultraviolet radiation because of its property to absorb ultraviolet light.

Hemolysis was studied on suspensions of P25TiO₂NPs (0.2 mg/mL and 0.02 mg/mL), vitaminB2@P25TiO₂NPs (0.2 mg/mL and 0.02 mg/mL) and vitamin B2 (0.2 mg/mL and 0.02 mg/mL) were prepared and mixed with 500 μL of anticoagulated blood (donated by Laboratorio de Hemoderivados, UNC) in a rate of 1/10. A solution of NaCl 10% was used as the positive control and PBS as the negative control. Then, the samples were irradiated using the LED described above for 3 and 6 h to simulate the light penetration into the skin. Also, a set of samples was kept in the dark as control. Finally, the samples were centrifuged and the absorbance at 540 nm was measured in the supernatants. The experiment was reproduced twice; the standard deviation was calculated and p-value < 0.05 were considered significant.
