Carbon Black (CB) can principally be taken up by swallowing. At present, there are no studies that investigate explicitly the release of nanoscale carbon black from products during use. Carbon black has not been approved for use in food in the EU.

 

Studies of the uptake of carbon black in calves have shown that the particles are mainly taken up by the small intestines’ Peyer’s patches[1].

Cell cultures of large-intestine cells exposed to concentrations of 10 µg particles per cm2 did neither exhibit stress symptoms nor did the carbon black cause cell-damaging effects. Moreover, a cell culture test for apoptosis proved negative [2].
