Rapid communications: antiperspirant induced DNA damage in canine cells by comet assay.

Author information

Pomona College, Claremont, California, USA.


Millions of people around the world use antiperspirants to decrease or eliminate body odors. Most antiperspirants contain aluminum zirconium or another form of aluminum as its active ingredient. The present investigation applied Comet assay to detect if Secret Platinum for women, Old Spice for men, or Crystal Natural produced DNA damage in Madin-Darby canine kidney cells (MDCKII). This study has shown that antiperspirants cause DNA damage on a single-cell level. Additionally, our data showed us that in general, Secret Platinum for women and Old Spice for men, produced equivalent damage. Crystal Natural, marketed as being safer or less damaging, induced the most extensive damage of all three antiperspirants tested.
