Alcohol hand sanitizer dispenser in an office in Poland . Alcohol and alcohol plus Quaternary ammonium cation based compounds comprise a class of proven surface sanitizers and disinfectants approved by the EPA and the Centers for Disease Control for use as a hospital grade disinfectant. [24]
Ethyl rubbing alcohol has an extremely bitter taste from additives. The specific gravity of Formula 23-H is between 0.8691 and 0.8771 at 15.56 °C (60.01 °F). Isopropyl rubbing alcohols contain from 50% to 99% by volume of isopropyl alcohol, the remainder consisting of water.
For example, ordinary vodka, gin, rum and tequila have an alcohol concentration typically around 40% alcohol by volume (80 proof), and liqueurs are typically around 20% alcohol (40 proof). [ 6 ] Everclear is also used as a household "food-grade" cleaner, disinfectant, or stove fuel alcohol because its fumes and odor are less offensive than ...
Products with 60% to 95% alcohol by volume are effective antiseptics. Lower or higher concentrations are less effective; most products contain between 60% and 80% alcohol. [84] In addition to alcohol (ethanol, isopropanol or n-Propanol), hand sanitizers also contain the following: [84]
Neutral spirit is legally defined as spirit distilled from any material distilled at or above 95% ABV (190 US proof) and bottled at or above 40% ABV. [5] When the term is used in an informal context rather than as a term of U.S. law, any distilled spirit of high alcohol purity (e.g., 170 proof or higher) that does not contain added flavoring may be referred to as neutral alcohol.

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 has been used as an antiseptic as early as 1363, with evidence to support its use becoming available in the late 1800s. [32] At times and places of poor public sanitation (such as medieval Europe), the consumption of alcoholic drinks was a way of avoiding water-borne diseases such as cholera. [33]
Bottle of 20% sodium dodecyl sulfate in distilled water for use in the laboratory. The critical micelle concentration (CMC) in water at 25 °C is 8.2 mM, [1] and the aggregation number at this concentration is usually considered to be about 62. [3] The micelle ionization fraction (α) is around 0.3 (or 30%). [4]
