- Lithopone, a zinc sulfide-based white pigment, has been used for over a century due to its excellent hiding power, low cost, and environmental friendliness. However, concerns about its potential toxicity have led to a gradual decline in its use. In contrast, titanium dioxide (TiO2) has emerged as a popular alternative due to its superior whiteness, high refractive index, and strong UV protection properties.
- 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.
It's also added directly to food; mainly for coloring, but also as a thickener and to keep some powdered food, like confectioner's sugar, from clumping.
The additive goes into a lot of personal care products to whiten and brighten colors and to make them opaque, like toothpaste and makeup.


Below 20% substitution, it is recommended to replace 1 kg of TiO2 with 1 kg of Lithopone.

We’re most often exposed to E171 through the foods we ingest. We find E171 in many food products, like popsicles, ice cream, gum, and more. Another way we ingest E171 is through pharmaceutical drugs. Many pills and capsules contain E171 as an inactive ingredient.

What Is Titanium Dioxide?
Food safety experts in the European Union (EU) have recently updated their safety assessment of TiO2 as a food additive. In Europe, TiO2 is referred to as E171, in accordance with European labelling requirements for food additives. The EU expert panel took into account toxicity studies of TiO2 nanoparticles, which to this point had not been considered relevant to the safety assessment of TiO2 as a food additive.
It is opaque and glossy, and provides bright whiteness with blue undertones.
Titanium dioxide is a mineral that’s used as a white coloring in a variety of products, including sunscreens, cosmetics, paints, and plastics. The pigment grade is also known as titanium white, pigment white 6, or CI 77891; it's the whitest and brightest of all known pigments.

titanium dioxide ph. By optimizing the pH of titanium dioxide in the paint formulation, manufacturers can ensure uniform dispersion and excellent coverage, resulting in a high-quality finish.
This regulation entered into force on 7 February 2022. However, the Regulation included a six-month transitional period to allow food businesses time to phase out the use of this food additive and to reformulate their products using suitable alternatives. This period will end on 7 August 2022.
There are many uses of titanium dioxide that we don't know about because they were made exempt from being on the package in 1977, said Faber, who added that nothing much has changed since – other than the FDA approving some other uses of the color additive, such as expanding the use of mica-based pearlescent pigments (prepared from titanium dioxide) as color additives in distilled spirits over recent years.
