Isopropyl alcohol also known as isopropanol or IPA, is the most common disinfectant and is widely used in pharmaceuticals, hospitals, clean rooms, and electronic or manufacturing medical devices. Different solutions, values of purity, concentration, and types of alcohol produce cleaning properties and useful disinfection when applied correctly; or dangerous consequences when used inappropriately.
Though, it is available for various household purposes. You can buy isopropyl alcohol in bulk from various online sources. This post will help you identify the main use, best practices, and disinfection properly with isopropyl alcohol. Likewise, you can see other posts on IPA as a universal cleaner and the importance of high-quality USP IPA.
Why is 70% the most effective concentration of isopropyl alcohol for disinfection?
Isopropyl alcohol, especially in solutions between 60% and 90% alcohol with 10-40% pure water, is very antimicrobial against bacteria, fungi, and viruses. After alcohol concentration fell below 50%, the use for disinfection drops sharply. In particular, the higher concentration of alcohol does not produce more desirable properties of bactericidal, virucidal, or fungicides.
Water presence is an important factor in destroying or inhibiting the growth of pathogenic microorganisms with isopropyl alcohol. Water acts as a catalyst and plays an important role in correcting vegetative cell membrane proteins. 70% of IPA solutions penetrate the more complete cell walls that permeate the entire cell, refuge to all proteins, and therefore microorganisms die.
