Ethyl and Isopropyl alcohol are the two most common types of antiseptics and disinfectants that are used to kill germs and create a hygienic environment. In studies, it is found that when both are diluted with water they become more effective in killing germs. However, both have similar content but they are different in properties, uses, and safety considerations.
If you’re planning to try these solutions at your home or any other place, it is important to learn both alcohol. So, let’s dive into this blog and understand them exactly.
Ethyl Alcohol vs Isopropyl Alcohol
The most well-known type of alcohol is ethanol or ethyl alcohol. It’s the kind of alcohol that people drink in mixed drinks. Ethanol has the chemical formula C2H5OH. Yeasts ferment glucose to naturally generate ethyl alcohol.
In addition to being added to drinks, it has antibacterial and disinfecting properties in medicine. It is normal practice to add ethanol to vehicle fuel. In the US, ethyl alcohol is present in more than 98% of gasoline.
On the other side, isopropyl alcohol is known as “rubbing alcohol.” Compared to ethyl alcohol, it has two more hydrogen atoms and one extra carbon in its chemical structure. The formula for it is C3H7OH. It is frequently used as a disinfectant and antiseptic, much like ethanol. Moreover, lotions, makeup, and face wipes include it.
The Common Uses of Ethanol and Isopropyl
Now, let us understand the uses of ethanol and Isopropyl:
Ethanol Uses:
- Beverages: It is present in beer, wine, and spirits in a way that is safe to consume for humans.
- Antiseptic and Disinfectant: Ethanol is effective against a wide variety of bacteria, it is frequently used in hand sanitizers and surface disinfectants.
- Solvent: Ethanol is used in the cosmetics and pharmaceutical industries to make lotions and perfumes, among other things, and to dissolve different chemicals.
- Fuel: To lower carbon emissions from gasoline, ethanol can be added to it or utilized as a biofuel in its pure form.
Isopropyl Uses:
- Disinfectant: As a disinfectant, isopropyl alcohol is frequently used in medical settings to clean skin, needles, and other surfaces.
- Solvent: Isopropanol is useful in industrial applications and for cleaning electronics since it dissolves oils and greases well.
- Antiseptic: To clean wounds and stop infections, isopropyl alcohol is frequently included in first aid kits.
- Washing in the home: Isopropanol leaves a streak-free finish after washing glass, mirrors, and other surfaces.
Ethanol vs. isopropyl- which is the best disinfectant?
Both ethanol and isopropyl alcohol are good disinfectants. But they just function a little bit differently. Let’s see how they are different.
Ethanol is especially powerful against viruses, such as coronaviruses and the flu virus. By dissolving lipids and denaturing proteins, it effectively kills or inactivates the pathogens. Whereas Isopropyl alcohol also works well against a variety of diseases, such as viruses and bacteria. Denaturing proteins and rupturing cell membranes are the related ways it functions.
In terms of safety, ethanol is harmless. But it is vital to remember that overindulging can result in alcohol poisoning, liver damage, and other health problems. Isopropyl alcohol is not recommended for consumption and can be poisonous. In severe situations, headaches and dizziness are signs of isopropyl alcohol poisoning.
Finally, we can say that both are different; ethanol can be consumable and a little unsafe for the environment while the other isopropyl is safe for the environment but not for consumption.

FAQs on Ethyl Alcohol vs. Isopropyl Alcohol
Can ethyl alcohol and isopropyl alcohol be used interchangeably for disinfection?
Both ethyl alcohol and isopropyl alcohol are effective disinfectants, but they are not always interchangeable. Ethyl alcohol is often used in hand sanitizers and medical wipes, while isopropyl alcohol is commonly used in industrial settings, for cleaning electronics, and in medical environments. It’s essential to follow product instructions and use each alcohol type as intended.
Is ethyl alcohol safe for consumption?
Yes, ethyl alcohol is the type of alcohol found in alcoholic beverages and is safe for consumption in regulated amounts. However, it is also used in non-consumable products like hand sanitizers, where it should not be ingested.
Is isopropyl alcohol toxic if ingested?
Yes, isopropyl alcohol is toxic if ingested and can cause severe health issues, including vomiting, dizziness, headache, and in severe cases, respiratory failure, or death. It is meant for external use only and should never be consumed.
Which type of alcohol is better for disinfecting surfaces?
Both ethyl alcohol and isopropyl alcohol are effective for disinfecting surfaces, but isopropyl alcohol is more commonly used due to its rapid evaporation rate and ability to kill bacteria, viruses, and fungi. Ethyl alcohol is also effective but may be more commonly used in settings where it could come into contact with skin or food.
Can ethyl alcohol and isopropyl alcohol be mixed together?
Mixing ethyl alcohol and isopropyl alcohol is generally not recommended as they have different chemical properties and intended uses. Mixing them could reduce their effectiveness or result in unintended side effects.
Which type of alcohol is better for hand sanitizers?
Ethyl alcohol is more commonly used in hand sanitizers because it is effective at killing germs and is safe for use on skin. Isopropyl alcohol can also be used but may be more drying to the skin.
How can I safely store ethyl and isopropyl alcohol?
Both types of alcohol should be stored in a cool, dry place away from heat sources and out of reach of children. Ensure that the containers are tightly sealed to prevent evaporation and contamination.
What are the typical concentrations of ethyl and isopropyl alcohol used for disinfecting?
For disinfecting, ethyl alcohol is typically used in concentrations of 60-90%, while isopropyl alcohol is commonly used in concentrations of 70-99%. The effectiveness of alcohol as a disinfectant depends on the concentration and contact time.
What should I do if someone accidentally ingests isopropyl alcohol?
If someone accidentally ingests isopropyl alcohol, seek immediate medical attention. Do not induce vomiting, as this can cause further damage. Contact poison control and follow their instructions while waiting for emergency medical help.
