Which chemicals are used on living tissue to hinder the growth of microorganisms?

Antiseptics are specifically designed to impede the growth of microorganisms on living tissue. These chemicals work by either killing bacteria or inhibiting their growth, making them suitable for use on skin and other body surfaces where infections may enter. Antiseptics are used in various settings, including surgical procedures and wound care, to ensure that the area remains free from harmful pathogens.

In contrast, options like glutaraldehyde and disinfectants are typically intended for use on inanimate surfaces rather than living tissues, as they may cause irritation or damage to skin. Halogens, while they can possess antiseptic properties, are often more concentrated in forms like bleach and used mainly for disinfecting surfaces or objects, rather than directly applied to living tissues. This makes antiseptics the appropriate choice for applications involving the protection of living tissue against microbial growth.
