The difference is in how each substance is used. Antiseptics are applied to living skin or tissue to prevent infection, whereas disinfectants are applied to surfaces, equipment or other inanimate objects. Disinfectants are stronger and more toxic than antiseptics because they are applied to surfaces, not living tissue.
What is the difference between disinfection and sterilization?
Disinfection and sterilization are both decontamination processes. While disinfection is the process of eliminating or reducing harmful microorganisms from inanimate objects and surfaces, sterilization is the process of killing all microorganisms. That is the main difference between sterilizing and disinfecting.
