Isopropyl alcohol is one of the most versatile and widely used chemical compounds found in homes, hospitals, and industries across the UK. Known for its quick-drying and disinfecting properties, it's essential in everyday cleaning and personal care. Whether you're using it to clean electronics or as a sanitizer, it delivers results fast and effectively. But how much do you really know about it?
What Is Isopropyl Alcohol?
Isopropyl alcohol, also called rubbing alcohol, is a colorless, flammable liquid. It evaporates quickly and has a strong odor. Its chemical formula is C₃H₈O. The most common concentrations are 70% and 99%.
It is used for:
-
Cleaning surfaces
-
Disinfecting wounds
-
Removing grease
-
Sanitizing hands
-
Electronic maintenance
Over 85% of UK households have a bottle of isopropyl alcohol at home, according to a 2024 survey by British Hygiene Monitor.
Top 10 Uses of Isopropyl Alcohol in the UK
-
Disinfecting Surfaces
Hospitals use 70% isopropyl alcohol for sterilizing surfaces. It kills 99.99% of bacteria and viruses when used properly. -
Cleaning Electronics
Phones, laptops, and keyboards collect germs. A soft cloth with isopropyl alcohol can clean and sanitize without leaving residue. -
Hand Sanitizer Base
Many hand gels contain isopropyl alcohol. It dries quickly and leaves no sticky feeling. -
Removing Sticky Labels
Got a stubborn sticker? A few drops of isopropyl alcohol will remove the residue with ease. -
Glass and Mirror Cleaner
It leaves no streaks and evaporates in seconds, making it ideal for mirrors, windows, and car glass. -
Degreasing Agent
Mechanics and engineers use isopropyl alcohol to remove oil, grime, and grease from tools. -
Medical Wipes
Used in swabs and prep pads before injections, isopropyl alcohol ensures skin is free from germs. -
Cleaning Makeup Tools
Brushes and sponges can hold bacteria. Soaking them in isopropyl alcohol keeps them clean and safe. -
Stain Remover
It works on ink, grass, and even bloodstains. Use a cotton pad to dab the stain away. -
Deodorizing Footwear
Spraying isopropyl alcohol inside shoes kills bacteria and removes odour.
How Does Isopropyl Alcohol Work?
Isopropyl alcohol works by breaking down cell walls of bacteria and viruses. It denatures proteins, which kills or inactivates microorganisms. Unlike water-based cleaners, it doesn’t leave moisture behind.
A 2023 study by Imperial College London confirmed that isopropyl alcohol is 80% more effective than regular soaps against viruses on surfaces.
Is 70% or 99% Isopropyl Alcohol Better?
70% isopropyl alcohol contains 30% water, helping it penetrate cell walls more effectively. It's better for disinfecting.
99% isopropyl alcohol evaporates too fast, making it more suited for electronics and technical cleaning where moisture is a problem.
Quick Comparison:
-
70% – Ideal for skin, surfaces, and medical use
-
99% – Best for electronics and industrial equipment
Safety Tips When Using Isopropyl Alcohol
Even though isopropyl alcohol is safe for home use, it should be handled with care:
-
Keep away from open flames. It’s highly flammable.
-
Use in well-ventilated areas. Fumes can irritate your eyes and throat.
-
Store tightly closed and out of children’s reach.
-
Do not drink. Ingestion is toxic and dangerous.
Quote from Dr. Sarah Hughes, Public Health Expert, UK:
"A little care goes a long way. Always follow usage guidelines for isopropyl alcohol, especially around children and pets."
