Isopropyl Alcohol, particularly in solutions between 60% and 90% alcohol with 10-40% purified water is rapidly antimicrobial against bacteria, fungi and viruses. Once alcohol concentration drop below 50%, usefulness for disinfection drops sharply. Notably, higher concentrations of alcohol don’t generate more desirable bactericidal, virucidal or fungicidal properties. The presence of water is a crucial factor in destroying or inhibiting the growth of pathogenic microorganism with Isopropyl Alcohol. 70% IPA solutions penetrate the cell wall more completely which penetrates the entire cell, coagulates all proteins and therefore the microorganism dies.
