Difference Between Antiseptics & Disinfectants

Antiseptics and disinfectants are chemicals that are used on people and objects to kill bacteria that can lead to illness and infection; however, these chemicals serve different roles, and the application of the wrong antibacterial can have adverse effects.

  1. Function

    • Antiseptics are designed to killing microorganisms on the skin. Disinfectants are used to kill microorganisms on inorganic objects.

    Uses

    • Antiseptics are often used prior to surgery and in hand washing. Disinfectants are often used in household cleaners.

    Strength

    • Antiseptics are not as strong as disinfectants and do not have the power to kill most of the bacteria and other microorganisms on surfaces.

    Types

    • Alcohol, chlorhexidine and anilides act as antiseptics. Glutaraldehyde, vantocil, phthalaldehyde and formaldehyde act as disinfectants

    Warning

    • Studies on mice have found that disinfectants can cause skin hardening, lesions, skin erosion and inflammation. Antiseptics do not have harmful effects when applied to the skin.
