Antiseptic products are designed to inhibit the growth of bacteria and reduce the risk of infection. The inclusion of alcohol or benzalkonium chloride in these products is significant because both of these ingredients are effective at killing a wide range of microorganisms. Alcohol acts as a potent antiseptic by denaturing proteins and dissolving lipids, thus disrupting the cell membrane of bacteria. Benzalkonium chloride, a type of quaternary ammonium compound, functions as a disinfectant and has antimicrobial properties, making it a popular choice in both medical and household antiseptics.

Other options suggest ingredients that either serve different functions or do not have an antiseptic effect. For example, vaseline or glycerin primarily serves as moisturizers or emollients, essential oils or fragrances are typically included for scent rather than efficacy against pathogens, and moisturizers or vitamins focus on skin nourishment rather than infection prevention. Thus, the presence of alcohol or benzalkonium chloride is crucial for the antiseptic properties that distinguish these products.
