Why is 70 alcohol a better disinfectant than 95 alcohol?

70 % isopropyl alcohol is by far better at killing bacteria and viruses than 90 % isopropyl alcohol. As a disinfectant, the higher the concentration of alcohol, the less effective it is at killing pathogens. Coagulation of surface proteins proceeds at a slower pace, thereby allowing the alcohol to enter the cell.

Why is 70 alcohol used for sterilization not 100?

The 100% isopropyl alcohol coagulates the proteins instantly by creating a protein layer that protects the other proteins from further coagulation.

Why is 70% the most effective concentration of isopropyl alcohol for disinfection?

Why Is 70% the Most Effective Concentration of Isopropyl Alcohol for Disinfection? 70% IPA solutions penetrate the cell wall more completely which permeates the entire cell, coagulates all proteins, and therefore the microorganism dies.

What is difference between rubbing alcohol and isopropyl alcohol?

Ethanol is more dehydrating, and we can feel that when we use it on our skin. It can make our skin feel tight and dry.
