Posted on Sephora's Facebook wall to get an answer to your question. This is their response:
Hi Kelly, the Foundation and Slanted eyeliner brush are synthetic. The Powder, Face contour, Crease and Shadow brush are natural.
They didn't answer when I asked them what animals fur was used to make the brushes though.
