Isopropyl Alcohol is a propyl alcohol isomer with antibacterial properties. Although the exact mechanism of isopropanol's disinfectant action is unknown, it has been suggested that it kills cells by denaturing cell proteins and DNA, interfering with cellular metabolism, and dissolving cell lipo-protein membranes. As an antiseptic, isopropanol is used in soaps and lotions.
Water, ethanol, and chloroform are all miscible with isopropyl alcohol. It dissolves ethyl cellulose, polyvinyl butyral, as well as a wide range of oils, alkaloids, gums, and natural resins. Isopropyl alcohol, unlike ethanol or methanol, is not miscible with salt solutions and can be separated from aqueous solutions by adding a salt such as sodium chloride. Salting out refers to the process of separating concentrated isopropyl alcohol into a distinct layer.
