Carbolic acid, also known as phenol, is a colorless, oily liquid with a distinct smell. It is derived from coal tar and is commonly used in the production of plastics, resins, and as a disinfectant. Due to its antiseptic properties, it was historically used in medical settings to sterilize instruments and clean wounds. In addition to its industrial applications, carbolic acid is a key ingredient in many household products, such as soaps and cleaners. However, it is important to handle it with care, as it can be toxic and cause skin irritation. Proper safety measures should always be followed when using products containing carbolic acid.
