Chemical Composition of Alcohol

Alcohol that can be bought on the counter is external alcohol. It is used for disinfection and can also be applied to the skin to produce a cooling effect.

Do you know the chemical composition of topical alcohol? It is a chemical mixture of denatured alcohol, water, and chemicals added to make alcohol difficult to drink. It may also include chemical colorants.

There are two common chemical types of topical alcohol:

Isopropyl alcohol


Isopropyl alcohol

Most topical alcohol is made from isopropanol or isopropanol in water.

The concentration of isopropyl topical alcohol usually ranges from 68% alcohol in water to 99% alcohol in water. 70% topical alcohol is very effective as a disinfectant.

Additives make the wine bitter and try to stop people from drinking it. Isopropanol is a toxic chemical product, partly because the body metabolizes it into acetone. Drinking this alcohol can lead to headaches, dizziness, nausea, vomiting, inhibition of the central nervous system, organ damage, and even coma or death.


Another topical alcohol is made of 97.5% to 100% denatured ethanol or ethanol plus water.

Alcohol is less toxic than isopropanol. It is the alcohol naturally found in wine, beer, and other alcoholic beverages.

However, alcohol is denatured or undrinkable in external alcohol, which is not only to control the toxicity of alcohol but also because the alcohol is not purified so that it can be drunk safely. In the United States, additives make it as toxic as isopropanol.

Topical alcohol in Britain

In Britain, topical alcohol is called "surgical alcohol". The formula consists of a mixture of ethanol and isopropanol.

Topical alcohol in the United States

In the United States, the external alcohol made of ethanol must comply with the molecular formula 23-h, that is, 100 parts by volume of alcohol, 8 parts by volume of acetone, and 1.5 parts by volume of methyl isobutyl ketone. The remainder of the composition includes water and denaturants, and can also include coloring agents and perfume oils.

According to the regulations, the external alcohol made of isopropanol contains at least 355 mg sucrose octaacetate and 1.40 mg dinaammonium benzoate per 100 ml. Isopropyl topical alcohol also contains water, stabilizer, and colorant.


All topical alcohol produced in the United States is toxic and can cause excessive skin dryness if used frequently. If you look at the product label, you will see warnings for the most common uses of external alcohol.

All types of topical alcohol, no matter from which country, are flammable. Nearly 70% of the formula is less likely to catch fire than external alcohol with higher alcohol content.
