Variations of titanium dioxide are added to enhance the whiteness of paint, plastics, and paper products, though these variations differ from the food-grade ones for things we eat (1Trusted Source, 2Trusted Source).
It's also used in sunscreens as a UV filtering ingredient, helping to protect a person's skin by blocking absorption the ultraviolet light that can cause sunburn and cancer.

When examining a lithopone pigment pricelist, one might notice that prices can vary significantly between different grades of lithopone. Generally, there are two main types Lithopone 28 and Lithopone 60, with the numbers denoting the percentage of zinc sulfide content. Lithopone 28, with a lower zinc sulfide content, is often more affordable compared to Lithopone 60, which offers superior whiteness and opacity. The choice between these grades depends largely on the specific requirements of the end application.
The global Lithopone market report provides in-depth competitive analysis as well as profiles of these major players.
We even use titanium dioxide when brushing our teeth as it’s found in many toothpastes.
Titanium dioxide is typically micronized and coated for use in cosmetics products. The micronizing makes this somewhat heavy-feeling ingredient easier to spread on skin, plus a bit more cosmetically elegant. Micronized titanium dioxide is much more stable and can provide better sun protection than non-micronized titanium dioxide.
People eating lots of candy should be more worried about the sugar and how it can cause high blood pressure and obesity, says Westerhoff.

French researchers studied how and where E171 nanoparticles enter the bloodstream, first studying the route through pigs and then in vitro with human buccal cells, for a 2023 study published in the journal Nanotoxicology. The research showed that the nanoparticles absorbed quickly through the mouth and then into the bloodstream, before damaging DNA and hindering cell regeneration.
Recent analyses of food-grade TiO2 samples have found that a significant portion of particles may be within the nanoscale. These particles (also known as nanoparticles) range in size from 1 to 100 nm, where 1 nm equals 1 billionth of a metre (the width of a typical human hair is 80,000 to 100,000 nm).
