According to, “Rubbing alcohol is either isopropyl alcohol or ethanol that is not designed for human consumption. Rubbing alcohol contains between 60% and 99% alcohol and it is typically used for wound disinfection as well as surface cleaning.” 

When you think of alcohol, you might get flashbacks to some horrible hangovers from college. But alcohol is so much more than an inebriating influence that makes college students make dumb decisions. It’s a potent disinfectant for wounds and a reliable cleaning agent. Most people have some rubbing alcohol in their medicine cabinets because it’s so versatile and useful.

While it has the word “alcohol” in it, rubbing alcohol in particular should not be in the punch at even the dodgiest shindig. Manufacturers add different solvents to rubbing alcohol to render it undrinkable. This process of adding toxins to rubbing alcohol is called “denaturing.” The reason why companies denature alcohol is simple. For some folks struggling with alcohol addiction or alcohol abuse, drinking rubbing alcohol might be a desperate measure to get alcohol into their systems. When rubbing alcohol is denatured, it deters people from trying to drink it. 

For companies, this eliminates liability around injury if someone drinks the rubbing alcohol. Denaturing also makes rubbing alcohol a different product from drinking alcohol. This is important when it comes to taxing the sale of alcohol. In the United States, legislation requires companies producing rubbing alcohol to denature it so the alcohol tax revenue isn’t affected. 

If rubbing alcohol wasn’t denatured, you’d have to show an ID to purchase it and companies could hurt from lawsuits based on drinking it with poor outcomes. If you do swallow rubbing alcohol on purpose or accidentally, you should call poison control and head to the emergency room. 

The active ingredient in rubbing alcohol is, well, alcohol. If you use it to cleanse a wound, it might sting or burn. Still, the benefit of lowering the risk of infection outweighs the temporary sting. For severe injuries or deep wounds, leaving cleansing to the professionals may be better. If you try using rubbing alcohol to clean a wound and have adverse effects, it’s important to seek proper medical advice.

Where does the name “rubbing alcohol” come from?

“Rubbing alcohol” coined its name back in the roaring 1920s because it was marketed as a massage aid. When people were giving massages with rubbing alcohol, I sure hope they didn’t have an unknown cut on their shoulders. They’d discover it really quickly when rubbing alcohol hit it! 

Over time, rubbing alcohol kept this name in the U.S. In other areas, such as the United Kingdom, “rubbing alcohol” is called “surgical spirit.” It’s always been called “surgical spirit” in the United Kingdom. This sounds like a more appropriate use and a whimsical name. 

As you may know, the 1920s marked a historical event called “Prohibition” in the United States. During Prohibition, alcohol of all kinds was banned for consumption. People tried to get around the ban in a variety of ways. People wanted to get loaded and weren’t about to let government legislation stop them. Some people made their own alcohol called “bootleg” alcohol or “moonshine.” Others took to participating in speakeasies. Speakeasies were underground bars that sometimes offered a classy, exciting secret drinking party experience. Others turned to rubbing alcohol. 

At the time, there was no legislation calling for manufacturers to make rubbing alcohol impossible to drink. As Prohibition came into full swing, authorities cracked down on the manufacturing of any alcohol. Once they got word that some people were sneaking swigs of rubbing alcohol, they shut it down. Prohibition-era legislation is part of what forces manufacturers in the United States of America to denature rubbing alcohol.

Is isopropyl alcohol the same as rubbing alcohol?
