Depending on the product, these antibacterial ingredients can be anything from citronella oil to antibiotics. Benzyl benzoate is an antibacterial ingredient found in original Dove deodorant. It has the chemical formula C6H5CO2C6H5 and serves the dual purpose of keeping microbials from breeding in the underarms and keeping microbials out of the deodorant itself.
