Isopropyl alcohol is one of the most widely used chemicals in homes, hospitals, and industries across the UK. Known for its fast evaporation and powerful disinfecting properties, it's a go-to solution for cleaning, sterilising, and removing grease. With rising concerns about hygiene and sanitation, demand for isopropyl alcohol has increased rapidly.
Used in concentrations ranging from 70% to 99%, it offers a powerful solution for killing bacteria, viruses, and fungi. But that’s not all—it’s also found in electronics cleaning, cosmetic formulations, and auto care.
This article explores the top uses, safety precautions, and expert recommendations for using isopropyl alcohol effectively in your daily life.
What is Isopropyl Alcohol?
Isopropyl alcohol, also known as IPA or rubbing alcohol, is a clear, colourless liquid with a strong odour. It’s a type of alcohol that contains carbon, hydrogen, and oxygen—making it volatile and quick-drying.
In the UK, it’s often sold in two common concentrations:
70% isopropyl alcohol – Best for disinfecting surfaces
99% isopropyl alcohol – Ideal for industrial use and electronics
Both grades are used depending on the application, but the 70% solution is generally preferred for killing microbes as it penetrates cell walls more effectively.
Top Uses of Isopropyl Alcohol in the UK
1. Surface Disinfection
Hospitals, clinics, and households use isopropyl alcohol to disinfect surfaces. Its quick evaporation makes it ideal for cleaning keyboards, mobile phones, countertops, and door handles.
“In healthcare, fast-acting disinfectants like isopropyl alcohol are essential for infection control,” – Dr. James Wilcox, NHS Consultant.
2. Medical and First Aid Applications
Isopropyl alcohol is used to clean wounds, sterilise instruments, and prep skin before injections. It’s gentle on skin in the right concentration and highly effective in reducing bacteria.
Key facts:
70% IPA kills 99.99% of bacteria within 30 seconds
Used by over 85% of UK medical facilities as a primary antiseptic
3. Electronics and Screen Cleaning
Technicians prefer isopropyl alcohol for cleaning sensitive components. It evaporates fast and leaves no residue, making it ideal for circuit boards, screens, and connectors.
4. Grease and Stain Removal
Isopropyl alcohol breaks down oils and sticky residues effectively. Whether it’s removing sticker glue from glass or cleaning engine parts, it’s a strong degreasing agent.
5. DIY and Household Cleaning
You can safely clean mirrors, tiles, bathroom fittings, and even stainless steel with isopropyl alcohol. It’s non-corrosive and cuts through grime.
Popular household uses include:
Sanitising makeup brushes
Cleaning kitchen appliances
Removing ink stains from fabric
Isopropyl Alcohol vs Ethanol: What’s the Difference?
While both are used as disinfectants, isopropyl alcohol is generally stronger and more effective at killing viruses and bacteria.
Comparison:
Isopropyl Alcohol: Strong odour, better for electronics, faster drying
Ethanol: Milder smell, used in hand sanitisers, food-safe
Both are flammable, but isopropyl alcohol evaporates quicker, which reduces residue on surfaces.
Safety Tips When Using Isopropyl Alcohol
Although isopropyl alcohol is widely used, it must be handled carefully. Always use in well-ventilated areas and store away from heat sources.
Follow these precautions:
Avoid contact with eyes and prolonged skin exposure
Keep away from flames and heat
Don’t ingest or inhale vapours for long periods
Use gloves if applying large quantities
Where to Buy Isopropyl Alcohol in the UK
You can find isopropyl alcohol at pharmacies, hardware stores, and online retailers. Amazon, Boots, Screwfix, and eBay offer multiple options in both 70% and 99% concentrations.
Top suppliers in the UK:
Chemiphase
LabChem
Isopropanol UK
The Soap Kitchen (for cosmetic grade IPA)
Look for products labeled “BP Grade” or “USP Grade” for medical or cosmetic use.
Best Concentration for Different Uses
70% Isopropyl Alcohol
Disinfecting skin and surfaces
Cleaning phones, remotes, and light switches
First aid and wound care
99% Isopropyl Alcohol
Electronics and circuit board cleaning
Solvent for paints and resins
Automotive cleaning and degreasing
For home use, 70% is generally safer and more versatile.
Environmental Impact of Isopropyl Alcohol
While isopropyl alcohol breaks down quickly in the environment, it’s still flammable and volatile. It should never be poured into drains or flushed. Always dispose of large amounts through hazardous waste channels.
Why Isopropyl Alcohol Became Essential During COVID-19
The demand for isopropyl alcohol surged during the pandemic due to its virus-killing properties. According to Public Health England, surface cleaning with IPA reduced transmission risks in public spaces by over 60%.
Even now, it's a staple in cleaning kits across offices, schools, and homes.
Common Myths About Isopropyl Alcohol
1. Higher percentage always works better – Not true. 70% is often more effective for killing germs due to slower evaporation.
2. Safe for all surfaces – IPA can damage plastics and painted surfaces. Always test before using.
3. Non-toxic – False. It can be harmful if ingested or used improperly.
Industrial Applications of Isopropyl Alcohol in the UK
Beyond households, isopropyl alcohol is used heavily in:
Automotive industries – For cleaning engine parts and brake lines
Printing – As a solvent in inks
Manufacturing – Degreasing tools and machinery
Cosmetics – Found in aftershaves, toners, and hand rubs
Its low cost and high efficiency make it a staple in multiple sectors.
How to Store Isopropyl Alcohol Safely
Always keep isopropyl alcohol in a cool, dry place away from direct sunlight. Use amber bottles or sealed containers to avoid evaporation.
Storage tips:
Keep out of reach of children
Label bottles clearly
Store below 25°C
Avoid metal containers which may react over time
Final Thoughts
Isopropyl alcohol continues to be a practical, affordable, and reliable solution for disinfection, cleaning, and industrial applications in the UK. Its fast action, versatility, and availability make it a must-have in homes, hospitals, and workshops.
With safety and proper use, it can serve multiple needs effectively. Whether you're wiping down your laptop or cleaning medical tools, isopropyl alcohol proves its value daily.
