The Scoop on Titanium Dioxide in Cosmetics
· Avoid titanium dioxide in powdered cosmetics, including loose and pressed powders, eyeshadows, and blush. Some sunscreens will say "non-nano" on the label. Choose those, and if the label doesn''t specify if titanium dioxide is nanoparticle size, call or email the company and ask the particle size of the active sunscreen ingredient.
Titanium dioxide (TiO2, also known as titanium (IV) oxide or titania) is the naturally occurring oxide of titanium.
