Denatured alcohol has no advantages for any purpose over normal ethanol; it is a public policy compromise. As denatured alcohol is sold without the often heavy taxes on alcohol suitable for consumption, it is a cheaper solution for most uses that do not involve drinking. If pure ethanol were made cheaply available for fuel, solvents, or ...
In biochemistry, denaturation is a process in which proteins or nucleic acids lose folded structure present in their native state due to various factors, including application of some external stress or compound, such as a strong acid or base, a concentrated inorganic salt, an organic solvent (e.g., alcohol or chloroform), agitation and radiation, or heat.

Denatured alcohol, also known as methylated spirit Denaturalization , the reverse of naturalization, when a state deprives one of its citizens of his or her citizenship Topics referred to by the same term
The addition of methanol, which is poisonous, renders denatured alcohol unfit for consumption, as ingesting denatured alcohol may result in serious injury or death. [2] Thus denatured alcohol is not subject to the taxes usually levied on the production and sale of alcoholic beverages. Aniline was used to denature colza oil in the 1980s. [3]
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.

Such production generally does not have any forensic significance because the ethanol is broken down before significant intoxication ensues. These trace amounts of alcohol range from 0.1 to 0.3 μg/mL in the blood of healthy humans, with some measurements as high as 1.6 μg/mL (0.002 g/L). [76]
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.
