Isopropyl rubbing alcohols contain from 50% to 99% by volume of isopropyl alcohol, the remainder consisting of water. Boiling points vary with the proportion of isopropyl alcohol from 80 to 83 °C (176 to 181 °F); likewise, freezing points vary from −32 to −50 °C (−26 to −58 °F). [6] Surgical spirit BP boils at 80 °C (176 °F). [7]
Care should be taken with electrocautery, as ethanol is flammable. [1] Types of alcohol used include ethanol, denatured ethanol, 1-propanol, and isopropyl alcohol. [6] [7] Alcohols are effective against a range of microorganisms, though they do not inactivate spores. [7] Concentrations of 60% to 90% work best. [7]
Isopropyl alcohol (IUPAC name propan-2-ol and also called isopropanol or 2-propanol) is a colorless, flammable, organic compound with a pungent alcoholic odor. [9]Isopropyl alcohol, an organic polar molecule, is miscible in water, ethanol, and chloroform, demonstrating its ability to dissolve a wide range of substances including ethyl cellulose, polyvinyl butyral, oils, alkaloids, and natural ...

Alcohol rub sanitizers containing at least 70% alcohol (mainly ethyl alcohol) kill 99.9% of the bacteria on hands 30 seconds after application and 99.99% to 99.999% [note 1] in one minute. [ 30 ] For health care, optimal disinfection requires attention to all exposed surfaces such as around the fingernails, between the fingers, on the back of ...
Alcohols have a high efficiency against enveloped viruses (60–70% ethyl alcohol) 70% isopropyl alcohol or ethanol are highly effective as an antimicrobial agent. In the presence of water, 70% alcohol causes coagulation of the proteins thus inhibiting microbial growth. Alcohols are not quite efficient when it comes to spores.
A mixture of 70% ethanol or isopropanol diluted in water is effective against a wide spectrum of bacteria, though higher concentrations are often needed to disinfect wet surfaces. [26] Additionally, high-concentration mixtures (such as 80% ethanol + 5% isopropanol) are required to effectively inactivate lipid-enveloped viruses (such as HIV ...
They are used to disinfect the skin before injections, among other uses. Diguanides including chlorhexidine gluconate , a bacteriocidal antiseptic which (with an alcoholic solvent) is considered a safe and effective antiseptic for reducing the risk of infection after clean surgery, [ 11 ] including tourniquet-controlled upper limb surgery.
