Applications of denatured alcohol
Denatured alcohol is often used as fuel and solvent. It can also be used as a cleaning aid.

Certain consumer products, like toothpaste, hand sanitizer and mouthwashes, contain this in small quantities.

Rubbing alcohol, used primarily for topical application, is also a type of denatured alcohol.

It's a good disinfectant, germicide and antiseptic. Hence, the name 'surgical spirit'.

Drinkable alcohol has also been used since prehistoric ages as an anesthetic.
