Antiseptic vs. Disinfectant: What's the Difference?
Edited by Aimie Carlson || By Harlon Moss || Updated on October 9, 2023
Antiseptics are agents applied to living tissue to inhibit microorganisms, while disinfectants are substances used on inanimate objects to kill pathogens.
Key Differences
Antiseptics are specifically formulated to be safe for application on living tissues, such as skin or mucous membranes. Disinfectants, in contrast, are designed for use on surfaces and can be harmful if applied to the body.
The primary goal of an antiseptic is to reduce the possibility of infection, while the objective of a disinfectant is to eliminate harmful pathogens from surfaces.
Common examples of antiseptics include hydrogen peroxide and iodine, which can be used on minor cuts or abrasions. Disinfectants, such as bleach or ammonia, are frequently found in household cleaning products.
While both antiseptics and disinfectants aim to mitigate the risks posed by harmful microorganisms, their application and composition vary greatly. It's crucial to use each for their intended purpose.
Antiseptics often come in solutions, creams, or gels suitable for direct skin application. Disinfectants are typically in sprays or wipes intended for cleaning surfaces.
