Why is 70% ethanol used not 100%

At a 70% concentration, however, the ethanol takes longer to evaporate and this longer contact time means that it is able to penetrate cells more effectively. The water in a 70% grade is also important in denaturing proteins. And 70% ethanol also tends to be cheaper and is less flammable [1].Water acts as a catalyst and plays a key role in denaturing the proteins of vegetative cell membranes. 70% IPA solutions penetrate the cell wall more completely which permeates the entire cell, coagulates all proteins, and therefore the microorganism dies.Overall, the 70% concentration of isopropyl alcohol strikes a balance between its antimicrobial effectiveness, ease of use, and safety, making it an ideal choice for disinfecting a wide range of surfaces and equipment in healthcare, laboratory, and household settings.
