Titanium Dioxide Anatase
What type of titanium dioxide used in sunscreens?
I am considering the purchase of titanium dioxide. So I found myself with the titanium dioxide (rutile anatase) – I do not know what that means rutile anatase, but the kind of titanium dioxide used to block solar? If please help. Best answer gets my vote
Anatase and rutile are two different minerals, but both the molecular formula dioxide titanium. The other mineral Brookite is. Rutile is the one you are looking for. Nanoscale particles of rutile are transparent to visible light, but very effective in absorbing ultraviolet radiation. UV absorption of rutile nano-sized particles is blue-shifted relative to bulk rutile, in so that the increase of UV light energy is absorbed by the nanoparticles. Therefore, used in sunscreens to protect skin against UV-induced. I hope I helped! links to Wikipedia reference source.
