Paige, I recently read an in-depth article on nano tech. Opponents were saying that things like nano shampoo, sun screen, impregnated clothing, or anything utilizing nano that comes in direct contact with the body has an unknown factor associated with it.
No one knows how these nano products may interact with the body and there's no regulatory agency protecting consumers at this time.
We're currently witnessing the wild, wild West of nano technology as it applies to consumer products.
They say that the majority of the products advertising nano tech don't use it at all. All marketing hype.
