While isopropyl alcohol and rubbing alcohol are often used synonymously, they are not necessarily the same.
Rubbing alcohol can be either ethanol or isopropyl alcohol that’s diluted with water. However, it is true that isopropyl alcohol is more commonly used as rubbing alcohol than ethanol is.
Isopropyl alcohol is a colorless multi-purpose compound that’s commonly utilized as a solvent due to its oil and resin absorption properties.
It’s highly flammable and volatile, and has a sharp, distinct smell. It’s produced using propylene hydration and acetone hydrogenation.
Some amount of caution is necessary when you work with isopropyl alcohol. Its flammability and volatility can have negative consequences on human health.
Moreover, inhaling its vapors can cause irritation in the respiratory tract. At high concentrations, isopropyl alcohol vapors can also result in headaches, dizziness, and unconsciousness.
Isopropyl alcohol should never be ingested, since it can cause nausea and cramping. It acts as an irritant when exposed to the skin and eyes, so it’s best to wear protective gloves and goggles while you work with it in a well-ventilated room.
Uses of isopropyl alcohol
Isopropyl alcohol has a wide variety of applications, and can be used as:
- A solvent, since it’s capable of dissolving a range of resins, oils, and other non-polar compounds that water can’t dissolve.
- An antiseptic, since it kills bacteria. It’s important that the concentration of alcohol be greater than 60% when it’s used as an antiseptic.
- A disinfectant, since it can kill fungi, bacteria, and viruses. Surface disinfectants should contain at least 60% alcohol by volume.
- A household cleaner when it’s diluted with water, since it can remove grease. It dries without streaks can therefore be used to clean mirrors and other shiny surfaces. It can even remove permanent marker stains by dissolving the ink.
Rubbing alcohol manufacturers produce the product in a range of strengths, most commonly 75–99% isopropyl alcohol by volume. Its use is purely external, and isopropyl-containing rubbing alcohol contains no ethanol.
The name “rubbing alcohol” comes from the United States in the 1920s, due to its use in massages as a liniment. This was during the Prohibition era, where it was necessary to differentiate between alcoholic beverages and rubbing alcohol so people didn’t drink it unwittingly.
