Methylated spirits, also known as denatured alcohol, are both primarily ethanol but with additives that make them poisonous, foul-smelling, and undrinkable. The main additive in methylated spirits is methanol, a highly toxic substance usually derived from wood stock. Denatured alcohol has a wider variety of additives, including isopropyl alcohol, acetone, and methyl ethyl ketone. Both are used as solvents and fuels, with denatured alcohol being used for cleaning, crafting, and outdoor activities, and methylated spirits being used for indoor or outdoor heaters, paints, lacquers, and cosmetics.

Denatured alcohol is ethanol with additives to make it poisonous, bad-tasting, foul-smelling, or nauseating
Denatured alcohol, also known as methylated spirits, metho, or meths, is ethanol with additives that make it poisonous, bad-tasting, foul-smelling, or nauseating. The main additive is typically methanol, a highly toxic substance derived from wood stock, which gives the mixture an unpleasant odour. Other common additives include isopropyl alcohol, acetone, methyl ethyl ketone, and methyl isobutyl ketone. The additives are included to prevent the recreational consumption of ethanol, which is the primary component of alcoholic beverages.
The addition of methanol to ethanol is particularly effective in deterring consumption due to its similar boiling point and toxic nature. Pyridine, another typical additive, further enhances the unpleasant odour of the mixture. Denatonium is often added to give the substance an extremely bitter flavour, while syrup of ipecac may be included to induce vomiting. These additives are carefully chosen to make the ethanol undrinkable without interfering with its functionality in other applications.
The formulation of denatured alcohol varies slightly across regions due to government regulations. For example, New Zealand has removed methanol from its government-approved "methylated spirits" formulation. The European Union has agreed on specific procedures for the complete denaturing of alcohol, specifying the quantities of additives required per hectolitre of absolute ethanol.
Denatured alcohol is used as a solvent and as fuel for alcohol burners and camping stoves. It finds applications in cleaning, crafting, and outdoor activities, including fire juggling and fuelling model locomotives. It is also used for indoor or outdoor heaters, as a disinfectant, and for sterilising medical equipment.
Despite the poisonous nature of denatured alcohol, it has been consumed as a surrogate alcohol, leading to serious health consequences, including blindness and death. This highlights the importance of the additives in deterring recreational consumption and the need for safe handling and storage to prevent accidental ingestion.

Denatured alcohol is used as a solvent, disinfectant, steriliser, window cleaner, and fuel
Denatured alcohol is a toxic, foul-smelling, and nauseating form of ethanol that is made unfit for human consumption. It is also known as methylated spirits, metho, or meths in Australia, Ireland, New Zealand, South Africa, and the United Kingdom. Denaturing does not alter the ethanol molecule, making denatured alcohol an excellent solvent for various projects. Denatured alcohol is used as:
A Solvent
Denatured alcohol is an excellent solvent and is used in the paints, lacquers, and varnish industry. It is also used in cosmetics such as toners and makeup brush cleaners. It is also used to thin shellac, making it easier to work with porous wood.
A Disinfectant and Steriliser
Denatured alcohol is an effective disinfectant and steriliser. It can be used to clean mirrors and windows, leaving a streak-free shine. It can also be used to sanitise areas such as liquid hand soap receptacles, hand towels, and door handles. It is also useful for pre-treating ink stains on textiles such as clothes, curtains, and upholstery.
A Fuel
Denatured alcohol is a cheap, clean-burning fuel used in oil heaters and camping stoves. It is also a convenient and safer alternative as it can be easily extinguished with water. However, it produces a colourless flame, so caution is necessary when using it as fuel.

Methylated spirits is ethanol mixed with methanol, with other chemicals and a purple dye sometimes added
Methylated spirits, also known as denatured alcohol, are very similar. Both are solvents or liquids used to dissolve substances. Methylated spirits is ethanol mixed with methanol, with other chemicals and a purple dye sometimes added. The ethanol is denatured by the additives, which make it poisonous, foul-smelling, bitter, and nauseating, thus deterring recreational consumption.
Methylated spirits is a clear, colourless liquid commonly used across most industrial industries and households. It is used as a disinfectant, steriliser, window cleaner, paint thinner, and solvent in the paints, lacquers, and varnish industry. It is also found in cosmetics such as toners and makeup brush cleaners. When diluted to about 65-70%, it can be used as rubbing alcohol.
The methanol additive is highly toxic and can cause blindness, brain damage, and death if consumed. It is added to deter consumption, as ethanol in its pure form is drinkable. Pyridine is another typical additive used to make the mixture unpleasant-smelling. Denatonium is often added to give the substance an extremely bitter flavour.
Methylated spirits are dyed with a distinctive purple colour, usually methyl violet, for safety reasons and to identify it visually. In Central and Eastern Europe, this was mandatory during the communist era. The dye can leave a residue on surfaces.
Methylated spirits is highly flammable and has a boiling point of 78°C and a flashpoint of 11°C.

Methylated spirits is used for indoor/outdoor heaters, paints, lacquers, cosmetics, and cleaning
Methylated spirits, also known as denatured alcohol, are used for a variety of purposes, including indoor/outdoor heaters, paints, lacquers, cosmetics, and cleaning.
Methylated spirits are perfect for use in indoor and outdoor heaters, such as alcohol burners and camping stoves. Its high flammability makes it a suitable fuel source for these applications. However, it is essential to exercise caution when handling methylated spirits due to its flammable nature.
In the paints and lacquers industry, methylated spirits serve as an effective solvent. It can be used to thin oil-based paints and clean paintbrushes. Both professionals and DIY enthusiasts may use methylated spirits interchangeably with white spirit for these purposes, depending on their personal preferences.
Methylated spirits are also found in various cosmetics, such as toners and makeup brush cleaners. When diluted to about 65-70%, it can be used as rubbing alcohol on the skin. However, it is important to note that methylated spirits can be harsh on the skin, and its rapid evaporation may not provide sufficient time to kill bacteria effectively.
Additionally, methylated spirits are useful for cleaning tasks. It can be employed as a window cleaner, spray and wipe disinfectant, and a sterilizer for medical equipment. Its disinfectant properties make it suitable for sterilizing surfaces and equipment, contributing to hygiene and sanitation.
Methylated spirits, or denatured alcohol, are essentially ethanol with additives that make it poisonous, unpalatable, and unsafe for consumption. These additives, such as methanol, pyridine, and denatonium, are included to deter people from consuming the substance recreationally. The presence of these additives distinguishes methylated spirits from pure ethanol, which is drinkable but subject to higher taxes and regulations.

Denatured alcohol is sometimes consumed as a surrogate alcohol, which can be dangerous
Denatured alcohol, also known as methylated spirits, is ethanol that has additives to make it poisonous, bad-tasting, foul-smelling, or nauseating to discourage its recreational consumption. Despite its poisonous content, denatured alcohol is sometimes consumed as a surrogate alcohol, which can be dangerous and even life-threatening.
The practice of denaturing alcohol is common to avoid the high tax and regulations on drinking alcohol. This denatured alcohol is used for industrial, disinfecting, and non-drinking uses. It is used as a solvent and as fuel for alcohol burners and camping stoves. However, some people may seek out denatured alcohol as a cheaper alternative to drinking alcohol, which can be extremely dangerous.
Denatured alcohol is made poisonous by adding toxic and/or bad-tasting additives such as methanol, benzene, pyridine, castor oil, gasoline, isopropyl alcohol, and acetone. These additives are chosen because they are toxic when ingested with alcohol. Methanol is commonly used because its boiling point is close to that of ethanol, and it is toxic. It is also skin-absorbent, so it can be harmful even if it comes into contact with the skin.
Consuming denatured alcohol can lead to blindness, serious illness, or death. During the thirteen-year prohibition of alcohol in the US, thousands died from drinking denatured alcohol. Even today, people struggling with alcohol use disorder may turn to denatured alcohol as an alternative source, which can be extremely dangerous and hinder their recovery.
It is important to note that denatured alcohol is not meant for consumption and should be used only as directed for household or industrial purposes. If consumed, it is important to seek medical attention, especially if one experiences seizures, difficulty breathing, or unconsciousness.
