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.

In addition, lithopone has a strong hiding power beyond zinc oxide. This means less lithopone will have greater coverage and masking power, saving you time and money. No need to worry about multiple coats or uneven finishes anymore - the hiding power of lithopone ensures a flawless, even look in a single application.
