- Moreover, TIO2's ability to generate hydrogen from water when exposed to light offers exciting prospects for sustainable energy production within factory walls
Other scientists, however, have called into question the experimental designs of such studies, citing inconsistent results specifically in studies used to test DNA damage.
Sunscreens made with mineral active ingredients, like titanium dioxide and zinc oxide, generally score well in EWG’s Guide to Sunscreens. They provide strong sun protection with few health concerns and don’t easily break down in the sun.
A significant body of research, mostly from rodent models and in vitro studies, has linked titanium dioxide with health risks related to the gut, including intestinal inflammation, alterations to the gut microbiota, and more. It is classified by the International Agency for Research on Cancer (IARC) in Group 2B, as possibly carcinogenic to humans.
Some food products will include titanium dioxide on their nutrition label. But again, it can be hard to tell for those who don't list the ingredient.
Inflammation of the intestines

The main concern with nanoparticles is that they are so tiny that they are absorbed into the skin more than we want them (ideally sunscreen should remain on the surface of the skin). Once absorbed they might form unwanted complexes with proteins and they might promote the formation of evil free radicals. But do not panic, these are concerns under investigation. A 2009 review article about the safety of nanoparticles summarizes this, to date, in-vivo and in-vitro studies have not demonstrated percutaneous penetration of nanosized particles in titanium dioxide and zinc oxide sunscreens. The English translation is, so far it looks like sunscreens with nanoparticles do stay on the surface of the skin where they should be.

1. Product information The MSDS should provide detailed information about the composition of the lithopone, including the percentage of barium sulfate and zinc sulfide. This information is crucial for determining the quality and suitability of the product for specific applications.


If you want to avoid titanium dioxide, Stoiber and Faber urge consumers to try and avoid processed foods as best as you can.
As a result, tariffs for titanium products are remaining similar to the ones in 2016, which will not cause bigger price fluctuations and keep a stable market.
It has strong tinting and hiding power, is resistant to alkali and heat, but will decompose when exposed to acid and darken when exposed to light. It has poor weather resistance and is easy to powder, so it is not suitable for outdoor use. In recent years, it has only been used in low-grade products.
Un pigment apparenté, mais où le sulfate de baryum est remplacé par du sulfate de calcium, prend le nom de « sulphopone »
