The ethanol is mixed with other chemicals to form an undrinkable solution. For many of these solutions, there is no practical way to separate the components. Labels such as "cannot be made non-poisonous" communicate to users that they should not trust any alcohol claiming to be rendered safe by distilling, filtering, or additives. Despite its poisonous content, denatured alcohol is sometimes consumed as a surrogate alcohol, which can result in blindness or death if (as was typical) it contains methanol.

Understanding Denatured Alcohol
Denatured alcohol is ethyl alcohol (ethanol) that has been treated to make it unfit for human consumption. This process is crucial to prevent misuse and avoid taxes associated with beverage alcohol.
Why Methyl Alcohol?
- Methyl alcohol, also known as methanol, is a common denaturant added to ethanol.
- It is toxic to humans; ingestion can lead to severe poisoning and even death.
Effects of Methyl Alcohol
- Methyl alcohol has a sweet taste, which can make it appealing; however, its toxicity is a significant safety hazard.
- The body metabolizes methanol into formaldehyde and formic acid, leading to metabolic acidosis and visual disturbances.
Other Denaturants
- While methyl alcohol is a popular choice, other substances can also be used to denature alcohol:
- Potassium cyanide: Highly toxic and not commonly used due to safety concerns.
- Chloroform: Also toxic and poses health risks, thus not a preferred option.
- Potassium chloride: Not toxic and does not serve the purpose of making alcohol unfit for consumption.
Conclusion
The primary goal of denaturing alcohol is to prevent its consumption while allowing it to be used for industrial and other purposes. Methyl alcohol is the most effective and widely used denaturant for this purpose, ensuring safety and compliance with regulations.
