What Is Isopropyl Alcohol?
Isopropyl alcohol, also called rubbing alcohol, is a colorless liquid with a strong odor. It's a type of alcohol made by combining water and propene. Available in concentrations ranging from 70% to 99%, it’s often used in medical wipes, hand sanitizers, and surface cleaners.
According to the British Medical Journal, isopropyl alcohol can kill 99.99% of bacteria, viruses, and fungi when used correctly. Its fast-drying property makes it ideal for quick clean-ups.
Top 10 Everyday Uses of Isopropyl Alcohol
1. Surface Disinfectant for Homes and Hospitals
Isopropyl alcohol is a go-to product for sanitising surfaces. It removes bacteria from countertops, doorknobs, and medical tools. NHS cleaning protocols recommend alcohol-based cleaners, especially during flu and virus outbreaks.
2. Electronics Cleaning Agent
Laptops, phones, and camera lenses often collect grime and germs. Isopropyl alcohol safely cleans without damaging delicate parts. It evaporates quickly and leaves no residue, making it perfect for tech maintenance.
3. Skin Antiseptic
Hospitals and clinics use isopropyl alcohol to clean skin before injections or minor surgeries. It lowers the risk of infections and helps keep wounds clean. It’s also a common ingredient in first aid kits.
4. Hand Sanitiser Base
Many alcohol-based hand sanitisers in the UK market contain isopropyl alcohol as the primary germ-fighting ingredient. WHO guidelines suggest using at least 70% concentration for effective hand hygiene.
5. Sticker and Label Remover
Sticky labels can be frustrating. A dab of isopropyl alcohol breaks down adhesive and makes removal easy. It’s especially useful for glass and metal surfaces.
6. Stain Removal from Fabric
Ink and oil stains come off more easily with isopropyl alcohol. Apply a small amount and blot gently. Many dry cleaners in the UK use it for tough stains.
7. Odour Eliminator
Isopropyl alcohol can neutralise strong odours in shoes, gym bags, and fabrics. Spray lightly and allow it to dry. It kills bacteria that cause bad smells.
8. Grease Cutter for Kitchens
It breaks down grease quickly, helping clean stovetops and hoods. Isopropyl alcohol works faster than soap on stubborn kitchen grime.
9. Mold and Mildew Treatment
In damp areas like bathrooms, isopropyl alcohol stops mold growth. Spray directly and scrub after 10 minutes for best results.
10. Cooling Agent for Fevers and Muscle Pain
Some parents use diluted isopropyl alcohol to cool children’s feverish skin. It also helps relieve sore muscles when used in rubs. Always follow healthcare advice before using on skin.
Is Isopropyl Alcohol Safe?
Used responsibly, isopropyl alcohol is safe. However, safety guidelines must be followed:
- Keep away from flames—it’s highly flammable
- Avoid inhaling large amounts
- Don’t drink it—it’s toxic
- Use gloves if you have sensitive skin
The UK’s Health and Safety Executive (HSE) advises using isopropyl alcohol in well-ventilated spaces to avoid dizziness or irritation.
Isopropyl Alcohol vs. Ethanol: What’s the Difference?
Though both are used as disinfectants, they differ in composition:
- Isopropyl alcohol is slightly stronger in removing oils and grease
- Ethanol is often used in beverages but also works in sanitizers
- Isopropyl has a stronger smell but evaporates faster
- Ethanol is more regulated due to its potential for consumption
In the UK, isopropyl alcohol is more common in industrial and medical use.
