A Guide to Antiseptics

Antiseptics and disinfectants are nonselective, anti-infective agents that are applied topically. In general, antiseptics are applied on tissues to suppress or prevent microbial infection. Disinfectants are germicidal compounds usually applied to inanimate surfaces. Sometimes the same compound may act as an antiseptic and a disinfectant, depending on the drug concentration, conditions of exposure, number of organisms, etc. To achieve maximal efficiency, it is essential to use the proper concentration of the drug for the purpose intended.

Antiseptics also have been used to treat local infections. However, in most cases, systemic chemotherapeutic agents are preferred, because they often penetrate better into the foci of infection and are less likely than the topical anti-infectives to lose their potency when in contact with body fluids and debris in the infected area.

Ideally, antiseptics and disinfectants should have a broad spectrum and potent germicidal activity, with rapid onset and long-lasting effect. They should not be prone to development of resistance in target microorganisms.

They should withstand a range of environmental factors eg, pH, temperature, humidity and must retain activity even in the presence of pus, necrotic tissue, soil, and other organic material. High lipid solubility and good dispersibility increase their effectiveness. Antiseptic preparations should not be toxic to the host tissues and should not impair healing.

Disinfectants should be nondestructive to applied surfaces. They should be readily biodegradable, not accumulate in the environment, or react with other chemicals to produce toxic residues.

Offensive odor, color, and staining properties should be absent or minimal. Most of these compounds exert their antimicrobial effect by denaturation of intracellular protein, alteration of cellular membranes often through extraction of membrane lipids , or enzyme inhibition.

Although most classes of antiseptics and disinfectants have been in use for decades, the emergence of microbial resistance to some agents, especially in the hospital environment, has led to continued research into the development of new compounds. From developing new therapies that treat and prevent disease to helping people in need, we are committed to improving health and well-being around the world.

Basic Principles and Introduction to Disinfectants and Antiseptics for Skin, Mucosa, and Wounds

Antiseptics are generally distinguished from antibiotics by the latter's ability to safely destroy bacteria within the body, and from disinfectants , which destroy microorganisms found on non-living objects. Some antiseptics are true germicides , capable of destroying microbes bacteriocidal , while others are bacteriostatic and only prevent or inhibit their growth. Antibacterials include antiseptics that have the proven ability to act against bacteria. Microbicides which destroy virus particles are called viricides or antivirals. Antifungals , also known as antimycotics , are pharmaceutical fungicides used to treat and prevent mycosis fungal infection. The widespread introduction of antiseptic surgical methods was initiated by the publishing of the paper Antiseptic Principle of the Practice of Surgery in by Joseph Lister , which was inspired by Louis Pasteur 's germ theory of putrefaction. Some of this work was anticipated by:.

Antiseptics and disinfectants are very similar in that they are both used for killing microorganisms. They are different from one another though in both the makeup of them, as well as the use of them. Antiseptics are used on living organisms, such as human skin, to kill any microorganisms living on the bodies surface. Disinfectants are used on non-living things, such as countertops and handrails, to kill the microorganisms living on that inanimate surface. Antiseptics are typically found to have a lower concentration of the particular biocide which is used in that product to clean the surface than that of a disinfectant.

Antiseptics and Disinfectants: Activity, Action, and Resistance

Test your knowledge

The purpose of this Guidance Document for Disinfectants and Sterilization Methods is to assist lab personnel in their decisions involving the judicious selection and proper use of specific disinfectants and sterilization methods. Antisepsis : A process involving the destruction or inhibition of mico-organisms in living tissue thereby limiting or preventing the harmful effects of infection. Antiseptic: Typically an antiseptic is a chemical agent that is applied to living tissue to kill microbes. Note that not all disinfectants are antiseptics because an antiseptic additionally must not be so harsh that it damages living tissue. Antiseptics are less toxic than disinfectants used on inanimate objects. Due to the lower toxicity, antiseptics can be less active in the destruction of normal and any pathogenic flora present. Autoclave: An autoclave is a high pressure device used to allow the application of moist heat above the normal-atmosphere boiling point of water.
