Rubbing alcohol, also known as surgical spirit in some regions, refers to a group of denatured alcohols commonly used as topical antiseptics. These solutions are primarily composed of either isopropyl alcohol (isopropanol) or ethanol , with isopropyl alcohol being the more widely available formulation.

If an alcohol thermometer utilizes a combination of ethanol, toluene, and pentane, its lower temperature range may be extended to measure temperatures down to as low as −200 °C (−328 °F). [3] However, the measurement temperature range c. −200 °C to 78 °C, is highly dependent upon the type of alcohol used.
Alcohol inhalation is a method of administering alcohol directly into the respiratory system, with aid of a vaporizing or nebulizing device or bag. It is chiefly applied for recreational use, when it is also referred to as alcohol smoking, but it has medical applications for testing on laboratory rats, and treatment of pulmonary edema and viral pneumonia.
Alcohol is removed from the bloodstream by a combination of metabolism, excretion, and evaporation. 90-98% of ingested ethanol is metabolized into carbon dioxide and water. [4] Around 5 to 10% of ethanol that is ingested is excreted unchanged in urine , breath , and sweat . [ 2 ]
The difference in volatility between water and ethanol has traditionally been used in the refinement of drinking alcohol. In order to increase the concentration of ethanol in the product, alcohol makers would heat the initial alcohol mixture to a temperature where most of the ethanol vaporizes while most of the water remains liquid. The ethanol ...

Temperature-dependency of the heats of vaporization for water, methanol, benzene, and acetone. In thermodynamics, the enthalpy of vaporization (symbol ∆H vap), also known as the (latent) heat of vaporization or heat of evaporation, is the amount of energy that must be added to a liquid substance to transform a quantity of that substance into a gas.
