Well, the PARTICLES are zinc but they're held in suspension in a
"natural base compound". The natural base vehicle prevents the tiny zinc
particles from exposure to air and thus oxidation. The purpose of the
particles is to pierce the thin oxidized layer to the metal underneath and
make an electrical connection. They're too small to be much of a problem; I
wouldn't worry about it - Penetrox is a recognized useful antioxidant.
