Acids antiseptic/disinfectant properties

Sahcyhc acid USP, EP, and other pharmacopeia grades are used medically as antiseptic, disinfectant, antifungal, and keratolytic agents. Sahcyhc acid is formulated in lotion or ointment formulations for the treatment of dandmff, eczema, psoriasis, and various parasitic skin diseases. Because the keratolytic property of this aromatic acid has use in the safe removal of dead skin cells from the surface of healthy skin, the acid is used in concentrated sahcyhc acid solutions or suspensions to remove warts and corns. In more dilute form, sahcyhc acid preparations have found use in dandmff and eczema treatment. Sahcyhc acid has been considered and found effective by the Advisory Committees to the FDA in various over-the-counter (OTC) dmg regulated uses. Among these are acne products, dermatitis, dry skin, dandmff and psoriasis products, and foot care products (24). 

Phenols are weak acids that are widely used for their antiseptic and disinfectant properties. Some phenols are used as antioxidants in foods and a variety of other materials. 

Phenol is a product of the refining of oil and coal tar and is used industrially in the manufacture of pharmaceuticals, plastics, rubber, and plywood. It has antiseptic, germicidal, and anesthetic properties and may be used in disinfectants and preservatives. It is used in small amounts in many over-the-counter products with antiseptic properties. It is also a common reagent in nucleic acid/molecular biology research and is used to denature and remove protein from preparations of DNA and RNA. 

However, the development of microbicidally active phenol derivatives started from phenol itself, from carbolic acid, the antiseptic properties of whidh were detected in 1860 and first used by Lister in 1867 to kill bacteria on medical instruments, surgical dressings and wounds. The development of chemical disinfection revolutionized progress in hospitals, particularly in surgery. It was possible to successfully employ and develop surgical techniques which in the past had been feasible but unpractical because of the associated unavoidable massive and generally fatal infections.
