Benzododecinium bromide is effective against gram-positive microbes. In lower concentrations, its activity against conditionally gram-negative microorganisms (such as Proteus, Pseudomonas, Clostridium tetani etc.) is uncertain. It is not effective against Mycobacterium tuberculosis and bacterial spores. Longer expositions may inactivate some viruses.[1]

Benzododecinium bromide is an active ingredient in the trademarked antiseptic product Ajatin produced in the Czech Republic. In place of bromide, the benzododecinium cation may be used with chloride or another anion.
