What are the substances need to make a denatured alcohol?

Denatured alcohol is ethyl alcohol (ethanol) that has been made unfit for human consumption by the addition of a denaturant, a substance that makes it poisonous or unpalatable. The most common denaturants are methanol, isopropyl alcohol, and acetone.

Other substances that can be used as denaturants include:

* Diethyl phthalate

* Toluene

* Pyridine

* Methyl ethyl ketone

* Denatonium benzoate

The amount of denaturant that is added to ethanol varies depending on the intended use of the denatured alcohol. The addition of a denaturant also makes it difficult to extract the ethanol from the mixture, which helps to prevent the production of illicit beverages.

Additional substances, such as colorants, may be added to denatured alcohol to make it more easily identifiable.

Denatured alcohol is used in a variety of applications, including:

* Fuel

* Solvent

* Cleaning agent

* Antiseptic

* Deodorant

* Hairspray

* Insect repellent

The use of denatured alcohol is regulated by law in many countries, and the specific requirements for denatured alcohol vary depending on the jurisdiction.
