What is the main difference between disinfectants and antiseptics?

The correct answer highlights that disinfectants are specifically designed to be applied to surfaces, while antiseptics are formulated for use on skin or living tissues. Disinfectants are typically stronger chemical agents that aim to eliminate pathogens on inanimate objects, such as countertops, medical instruments, and floors. They undergo rigorous testing to ensure they effectively kill harmful microorganisms on non-living surfaces.

Antiseptics, on the other hand, are formulated to be safe for living tissues. They are used to reduce the possibility of infection when applied directly to the skin, such as before surgical procedures or in wound care. Their composition is such that they can effectively inhibit microbial growth without causing damage to human cells.

Understanding the distinct roles of these two types of agents is critical for proper infection control practices in healthcare settings, as using one in place of the other can lead to ineffective disinfection or irritation and potential harm to patients.
