Synthesis of vitaminB2@P25TiO₂NPs

Lithopone is manufactured by a process (Fig. 1) in which barium sulfide solution is prepared by reducing barite ore (BaSO ₄) with carbon and leaching the resulting mass.

Titanium dioxide is found in pretty much all makeup & sunscreen.

And studies have long shown that products applied to the skin end up in the bloodstream within half an hour. With penetration rates depending on where they are applied. Absorption rates for your face & scalp are 5-10 times higher than on other parts of our body (Hotchkiss 1994).

Not to mention that in 2005, the Environmental Working Group published a combination of two studies that found toxic chemicals in the umbilical cord blood of newborn babies born in the U.S. They screened for more than 400 chemicals, and an astounding 287 toxins were detected within the umbilical cord blood of these newborns. Of these 287 chemicals, 217 were neurotoxins, and 208 are known to damage growth development or cause birth defects.

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.

While the anatase titanium dioxide market is robust, it faces challenges such as regulatory compliance and environmental concerns related to extraction and processing. Manufacturers are increasingly adopting sustainable practices, focusing on recycling materials and minimizing waste in production processes. Innovations in nanotechnology are also leading to the development of more efficient and eco-friendly synthesis methods that can further enhance the properties of anatase TiO2.
