Titanium Dioxide is a naturally occurring mineral found in two forms,rutile and anatase. Both of these forms contain pure Titanium Dioxide that is bound to impurities. It is chemically processed to remove the impurities.Thus leaving the pure white pigment available for use. It has a variety of uses but I will stick to the cosmetic .
It serves several purposes.The main one is as a Sunscreen.
Some studies have pointed to this substance as a carcinogen.This has put fear into consumers. Are these claims true? What is important to note is that the only time in any of the studies done the problem occurred only when ultra fine or nano particles were use on lab rats.
So the problem will only arise when the particles are made small enough to work their way down into the human body or bloodstream and then only at very large quantities.
What does this mean to the average consumer? Well I take it to mean that we should avoid using Micoronized mineral pigments either in sunscreens or color cosmetics.
Course or fine particles should be safe . It is only the MICRONIZED mineral particles that should be avoided as they can make their way down to the lower levels of the skin.
Over all most of the studies have found this substance safe and a good sunscreen. So once again ,read your labels and also do your own research on this substance if you are still unsure.
I am basing my opinions on the several articles of research on this subject.
