<p>Isopropyl Alcohol is an isomer of propyl alcohol with antibacterial properties. Although the exact mechanism of isopropanol&#39;s disinfecting action is not known, it might kill cells by denaturing cell proteins and DNA, interfering with cellular metabolism, and dissolving cell lipo-protein membranes. Isopropanol is used in soaps and lotions as an antiseptic. 70 % isopropyl alcohol solution kills microorganisms by dissolving plasma membrane of the cell wall.<br />
