tio2 used in paint supplier
Overwhelmingly, research that’s relevant to human eating patterns shows us that E171 is safe when ingested normally through foods and drugs (1,2).
Hiding power
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.
