carbolic acid
Meaning of carbolic acid: Carbolic acid, chemically known as phenol, was historically significant as the first widely used surgical antiseptic before becoming mainly an industrial chemical.
Definition of carbolic acid
Carbolic acid is an older common name for phenol, a chemical compound originally derived from coal tar and also found naturally in some plants and essential oils. In its pure form, carbolic acid is a caustic, corrosive substance capable of causing significant chemical burns to skin and tissue.
Carbolic acid holds a notable place in medical history as the antiseptic that surgeon Joseph Lister famously used to sterilize surgical instruments and wounds, an approach that substantially reduced deaths from postoperative infection and helped establish the modern practice of antiseptic surgery.
Today, carbolic acid is used mainly as an industrial chemical, serving as a starting material in the manufacture of plastics, nylon, and various other synthetic compounds, and in diluted, carefully controlled forms it still appears in some germicidal and disinfectant products, though its once central role in surgical antisepsis has long since been replaced by other methods.
Also known as
Used in a sentence
Carbolic acid was historically used to disinfect surgical instruments before modern antiseptic techniques were developed.
Good to know
Carbolic acid's antiseptic use in surgery has been superseded by other antiseptic and sterilization methods, so it is encountered today mainly as an industrial chemical rather than as a surgical antiseptic.
Word origin
Where “carbolic acid” comes from
Formed from carbo-, referring to its origin in coal tar, and -ol, indicating a hydroxyl bearing compound similar to an alcohol, though phenol is chemically distinct from true alcohols.
