What distinguishes antiseptics from disinfectants?

The distinction between antiseptics and disinfectants is primarily based on their intended uses. Antiseptics are formulated for application on living tissues, such as skin and mucous membranes, to reduce the risk of infection. This makes them suitable for practices like hand washing, applying to wounds, or pre-surgical scrubbing. On the other hand, disinfectants are designed for use on inanimate surfaces, such as countertops, medical equipment, or floors, to eliminate or reduce the presence of pathogens.

Understanding this differentiation is essential in healthcare and microbiology, as using antiseptics on surfaces or disinfectants on skin could lead to adverse effects or ineffective microbial control. Therefore, the correct choice accurately highlights the primary functional distinction between these two types of antimicrobial agents.
