Alcohol-based hand sanitizers play an important role in reducing illness-causing germs on your hands. The World Health Organization (WHO) amp; Centers for Disease Control and Prevention (CDC) recommend the use of alcohol-based hand sanitizer in healthcare settings because it is safe, convenient, amp; highly effective.
Isopropyl alcohol, particularly in solutions between 60% amp; 90% with 10-40% purified water, is rapidly antimicrobial against bacteria, fungi, amp; viruses. 70% solutions penetrate the cell walls more completely, which permeates the entire cell, coagulates all proteins, amp; therefore the microorganism.
The CDC's baseline for effectiveness, especially against SARS-CoV-2 is a hand sanitizer made up of at least 60% alcohol.
