Nano-hydroxyapatite to be banned in the EU

Nano bone and teeth mineral aka nano hydroxyapatite, why would that be banned?

Nanomaterials in cosmetics, although the use of nano tubes to deliver medicine is like a basic step towards making food in the same sense as lab grown meat could deliver custom ratios of amino acids and other chemicals which wouldnt be found in the normal animal.

Perhaps these nanomaterials are bypassing the usual digestive methods in order to enter the body and this creates a new attack vector for the body to deal with, knowing its not evolved to deal with these new forms of chemicals.

Is this like an asbestos is to lungs situation in the making? Time will tell.
