What You'll Learn
Denatured alcohol is ethanol with additives
Denatured alcohol is essentially ethanol with additives that make it unfit and unsafe for human consumption. It is also known as methylated spirits, metho, or meths in Australia, Ireland, New Zealand, South Africa, and the United Kingdom, and as denatured rectified spirit. The ethanol in denatured alcohol is modified with additives to make it poisonous, bad-tasting, foul-smelling, or nauseating to discourage recreational consumption.
The most common additive used in denatured alcohol is methanol (methyl alcohol), which is highly toxic when consumed orally. The typical amount of methanol added is 5 to 10 percent, and it gives rise to the term "methylated spirits." Other common additives include isopropyl alcohol, acetone, methyl ethyl ketone, and methyl isobutyl ketone. These additives are chosen for their ability to make the ethanol unsuitable for drinking, either by adding a bad taste or smell, or by making it poisonous.
Denatured alcohol is used in a variety of products, including hand sanitizers, medical disinfectants, and household cleaners. It is also used as a lower-cost solvent or fuel for home or industrial use. The diversity of industrial uses for denatured alcohol has led to the development of hundreds of additives and denaturing methods. For example, in the United States, a specially denatured alcohol (SDA) is a combination of ethanol and another chemical substance, such as ethyl acetate, added to render the mixture unsuitable for drinking.
The term "denatured alcohol" specifically refers to alcohol products that have been adulterated with toxic and/or bad-tasting additives. These additives can include methanol, benzene, pyridine, castor oil, gasoline, isopropyl alcohol, and acetone. The addition of these substances makes denatured alcohol exempt from federal excise taxes imposed on pure, non-denatured ethanol. However, other taxes, permits, or licenses may still be required for its purchase.

Additives make it unfit for human consumption
Denatured alcohol is ethanol with additives that make it unfit for human consumption. It is also known as methylated spirits, metho, or denatured rectified spirit. The additives are introduced to make the alcohol poisonous, bad-tasting, foul-smelling, or nauseating to discourage recreational consumption.
The most common additive is methanol (methyl alcohol), which is highly toxic when consumed orally. Methanol is used because its boiling point is close to that of ethanol, and because it is toxic. Methanol is also added to ethanol to produce denatured alcohol. Pyridine and methanol, together, make denatured alcohol poisonous; denatonium makes it bitter. Other common additives include isopropyl alcohol, acetone, methyl ethyl ketone, and methyl isobutyl ketone.
Denatured alcohol is used as a solvent and as fuel for alcohol burners and camping stoves. It is also used in cosmetics and skincare products as a drying agent. It is added to hand sanitizers, medical disinfectants, and household cleaners.
The term "denatured alcohol" refers to alcohol products adulterated with toxic and/or bad-tasting additives, making them unsuitable for human consumption. The introduction of these additives puts denatured alcohol in a different tax category, making it cheaper to produce than liquor. It is also sometimes dyed so that it can be identified visually and to make it difficult to use distillation or other simple processes to reverse the denaturation.

Denaturing agents include methanol, isopropyl alcohol, acetone
Denatured alcohol is ethanol with additives that make it unfit for human consumption. It is also known as methylated spirits, meths, or denatured rectified spirits. The additives are chosen to make the alcohol poisonous, bad-tasting, foul-smelling, or nauseating to discourage its recreational consumption.
Denaturing agents include methanol, isopropyl alcohol, and acetone. Methanol, also known as methyl alcohol, is the main additive used in denatured alcohol, usually comprising 5 to 10 percent of the mixture. It is highly toxic when consumed orally. Methanol is used because its boiling point is close to that of ethanol, and because it is toxic. Methanol is colourless and odourless, so to prevent accidental ingestion, denatured alcohol is often dyed and has bittering agents added.
Isopropyl alcohol is another denaturing agent that shares many of the same uses as denatured alcohol. It is a chemically different type of alcohol but is also dangerous for human consumption. Isopropyl alcohol is often used as a disinfectant and is commonly found in hand sanitizers, medical disinfectants, and household cleaners.
Acetone is another denaturing agent used in denatured alcohol. It is a toxic substance that is also used as a solvent.
Other common additives in denatured alcohol include methyl ethyl ketone, methyl isobutyl ketone, pyridine, and denatonium benzoate. These substances are chosen for their ability to make the alcohol unpalatable and unfit for human consumption, either by adding a bitter taste, an unpleasant odour, or by making the mixture poisonous.

Denatured alcohol is used in hand sanitizers, disinfectants, cleaners
Denatured alcohol is ethyl alcohol with additives that make it unfit for human consumption. It is also referred to as "methylated spirits", derived from the fact that its main additive is usually 10% methanol (methyl alcohol). Other common additives include isopropyl alcohol, acetone, methyl ethyl ketone, and methyl isobutyl ketone. Denatured alcohol is added to cosmetics and is widely used in hand sanitizers, disinfectants, and cleaners.
Denatured alcohol in hand sanitizers
Denatured alcohol and isopropyl alcohol are the two most common active ingredients found in hand sanitizers. They are the only two alcohols that are FDA-approved for use in alcohol-based hand sanitizers. They are safe to apply to the skin and are effective disinfectants. However, alcohol can cause skin reactions in some people, such as contact irritant dermatitis.
Denatured alcohol as a disinfectant
Denatured alcohol is a powerful disinfectant that is often used on small surfaces and equipment in healthcare facilities. It is effective against the influenza virus and is considered superior to isopropyl alcohol. However, it is flammable, so its use should be limited to small surface areas and well-ventilated spaces.
Denatured alcohol as a cleaner
Denatured alcohol is a highly effective solvent and cleaning agent. It can be used to remove dirt, grease, glue, wax, and other types of grime from hard surfaces such as wood, glass, and plastic. It is also useful for removing stains, such as berry stains and grass stains, from clothing. In industrial settings, denatured alcohol is used as a solvent in products such as shellac and paint thinner.

Ethyl alcohol is also known as ethanol
Denatured alcohol is ethanol, or ethyl alcohol, that has been modified with additives to make it unfit for human consumption. Ethanol is produced naturally when yeast and other microbes ferment sugars found in plants. It is the type of alcohol found in alcoholic beverages.
Ethyl alcohol, or ethanol, has the chemical formula C2H6O. It is also known as spirits of wine and is the primary ingredient in spirits such as vodka, gin, and most liqueurs. Pure ethanol is considered food grade and is safe for consumption and use on the body and skin. It is also used as an eco-friendly alternative to gasoline for automobiles.
Denatured alcohol, on the other hand, is ethanol that has been deliberately altered to make it unsafe and unfit for human consumption. This is done by adding substances or denaturing agents such as methanol, benzene, pyridine, castor oil, gasoline, isopropyl alcohol, acetone, and methyl ethyl ketone. These additives are toxic, bad-tasting, foul-smelling, or nauseating, and they can have severe health effects if ingested. The most common additive is methanol, also known as methyl alcohol, which is highly toxic when consumed orally.
The term "methylated spirits" arises from the use of methanol as an additive. Denatured alcohol is also known as "denatured rectified spirit" or simply "rectified spirit," referring to the process of rectification or purification that ethanol undergoes before being deliberately denatured.
The addition of these denaturing agents serves several purposes. Firstly, it makes the ethanol unsuitable for recreational consumption due to its unpleasant taste, smell, or potential health risks. Secondly, denatured alcohol is often used as a lower-cost solvent or fuel for home or industrial applications, where the purity of ethanol is not required. By denaturing the alcohol, producers can avoid the federal excise taxes imposed on pure, non-denatured ethanol.
