Isopropyl alcohol is one of the most widely used chemicals in homes, hospitals, and industries across the UK. Commonly referred to as rubbing alcohol, it plays a vital role in cleaning, sanitising, and more. With its fast-evaporating and powerful antibacterial properties, isopropyl alcohol has become a staple in many households and workplaces. In this guide, we’ll uncover everything you need to know about this essential solution.
What is Isopropyl Alcohol?
Isopropyl alcohol, also known as 2-propanol, is a clear, colourless liquid with a strong odour. It’s a type of alcohol used mainly for cleaning and disinfecting. Available in various concentrations, the most popular ones are 70% and 99%. The 70% variant is preferred for general use as it penetrates cells more effectively.
According to the British Journal of Medical Practitioners, isopropyl alcohol kills 99.99% of bacteria, viruses, and fungi within seconds of contact.
Top 7 Uses of Isopropyl Alcohol in the UK
1. Disinfecting Surfaces
Isopropyl alcohol is highly effective at killing germs on hard surfaces. It's used in hospitals, clinics, and homes to wipe down:
-
Doorknobs
-
Phones
-
Remote controls
-
Keyboards
-
Countertops
Its quick drying nature makes it ideal for areas that require frequent disinfection.
2. Cleaning Electronics
Dust, grease, and fingerprints easily collect on electronics. A small amount of isopropyl alcohol on a microfiber cloth works well to clean:
-
Laptop screens
-
Smartphones
-
Computer parts
-
TV screens
Ensure the device is powered off before applying any liquid.
3. First Aid and Skin Antiseptic
Isopropyl alcohol has long been used as a first aid solution. It helps clean minor cuts and scrapes, reducing the risk of infection. NHS guidelines also recommend using rubbing alcohol to sterilise tweezers and other instruments.
“Alcohol-based solutions like isopropyl alcohol remain essential in infection control,” says Dr. Janet Reed, senior infection specialist, UK.
4. Removing Sticky Residue
If you've ever struggled with sticky labels or glue marks, isopropyl alcohol offers a quick fix. Apply a small amount and gently rub the area. It breaks down adhesives without damaging most surfaces.
5. Deodorising and Cleaning Shoes
Bad odour in shoes? A few sprays of isopropyl alcohol kill bacteria and leave them fresh. It’s safe on most materials, including leather and canvas. Let them dry completely before wearing.
6. Preventing Acne and Oily Skin
Though not for daily use, isopropyl alcohol can reduce oil and bacteria on skin. Apply with a cotton pad to oily areas. However, overuse can lead to dryness, so use it sparingly and moisturise after.
7. Cleaning Makeup Tools
Brushes and sponges collect bacteria over time. Dipping them in isopropyl alcohol cleans and sanitises them quickly. Makeup artists across the UK rely on this trick to keep tools safe.
Why 70% Isopropyl Alcohol is Preferred Over 99%
Most users assume a higher concentration works better. But science says otherwise. A 70% solution contains water, which slows evaporation and allows better penetration of the cell walls of microbes. This leads to a more effective kill rate. In contrast, 99% alcohol evaporates too fast to do the job thoroughly.
Isopropyl Alcohol vs Ethanol: What’s the Difference?
Both are used for disinfection, but isopropyl alcohol is more commonly used in medical settings in the UK. Here’s why:
-
Isopropyl alcohol is less drying on skin.
-
It evaporates more quickly.
-
It has a stronger bactericidal effect.
Ethanol, on the other hand, is more effective against some viruses but may leave a sticky residue.
Is Isopropyl Alcohol Safe for Home Use?
Yes, if used with care. Always use it in a well-ventilated space. Avoid open flames, as it's flammable. Keep it out of reach of children. Never ingest it or use it near eyes.
According to the UK Poison Centre, accidental ingestion cases are rare but dangerous. Always label your bottles clearly.
