Final answer:
An antiseptic is a safe antimicrobial chemical for skin application to prevent or reduce infection. Examples include hydrogen peroxide and isopropyl alcohol. Antiseptics help maintain hygiene and control the spread of infections.
Step-by-step explanation:
An agent that can be used safely on the skin to prevent or reduce infection by eliminating or decreasing the growth of microorganisms is known as an antiseptic. Antiseptics are antimicrobial chemicals that are suitable for application on living tissues, and they play a crucial role in infection control. Examples include hydrogen peroxide and isopropyl alcohol. These agents work by reducing the microbial load through the use of mild chemicals and are generally designed to increase the efficacy against a broader range of bacteria, enhance stability, and decrease toxicity. While antiseptics do not necessarily kill all microbes, they are critical in maintaining hygiene, preventing infections on the epidermis, or controlling the proliferation of existing infections. These substances are particularly important in healthcare settings where the risk of infection is higher and stringent sanitation practices are necessary.
