But this is just the tip of the ice berg so many articles & studies are coming out challenging the safety of Titanium Dioxide in our food supply & personal care products.
Scattering is strong when the difference in the refractive index of particle & matrix, Δn = np - nm, is big
The refractive index of binders used in coatings and inks is around 1.55. Titanium Dioxide is preferably used as a scattering source because the pigment does not absorb visible light and it has a high refractive index.
