If you use the 99% solution on a virus or bacterium, it will coagulate the proteins on the surface too quickly, forming a protective layer that shields the interior microbes from the alcohol. While the terms are often used interchangeably, there is a distinct difference between them that impacts their effectiveness and safety.
Why "Rubbing Alcohol" Isn't Always Isopropyl Alcohol
Feature Isopropyl Alcohol Rubbing Alcohol Common Concentration 91% – 99% 70% – 75% Additives None (pure) Denaturants / Bittering agents Primary Use Electronics, industrial cleaning First aid, surface disinfection Safety for Skin Drying, harsh on prolonged contact Drying, but slightly milder due to dilution Efficacy in Disinfection and Cleaning One might assume that the stronger the solution, the better the germ-killer, but science tells a different story. Isopropyl alcohol, in its purest form, is a singular compound often referred to as 100% IPA.
Concentration and Purity Levels When you look at the label, you will notice a stark contrast in Alcohol By Volume (ABV) percentages. Understanding the relationship between these two substances is the first step in using them correctly and maximizing their utility in your home or workspace.
The Difference Between Rubbing Alcohol and Pure Isopropyl Alcohol
Pure isopropyl alcohol is typically found at concentrations of 99% or 91%, depending on the grade. For general household cleaning, such as doorknobs, countertops, and remote controls, rubbing alcohol is the superior choice for killing germs.
