Why you Need to Choose 70% IPA Disinfectant
The common and widely used disinfectant in the pharmaceutical industry, hospitals and other healthcare facilities is 70% isopropyl alcohol. It is used for the disinfection of hands, equipment, hard surfaces and surgical devices.
It Kills Micro-Organisms!
The important thing is that only 70% solution of isopropyl alcohol acts as a disinfectant - killing all surface microorganisms. 70% isopropyl alcohol solution kills microorganisms by dissolving the plasma membrane of the cell wall. Plasma membrane of gram negative bacteria consists of a thin layer of peptidoglycan that can easily be destroyed by the alcohol.
Is 70% or 100% isopropyl alcohol better for killing germs?
70% alcohol is recommended to kill bacteria and to use as a disinfectant. This is because the added water content slows down the evaporation rate which means the isopropyl alcohol has longer contact with the surface, increasing the effectiveness of killing the germs. Because the isopropyl alcohol has more content time, it has a better response in killing bacteria. This is also why 70% is recommended.
