Alcohol is commonly used as a disinfectant due to its ability to kill bacteria and some viruses. It works primarily by denaturing proteins, which disrupts the protein structures of microorganisms and leads to their death.
One common misconception is that higher concentrations of alcohol, such as 95%, are more effective. Although 95% alcohol can quickly coagulate proteins on the surface of bacteria, it acts too rapidly and thus prevents it from penetrating deeply enough to kill all microorganisms. This results in incomplete disinfection, allowing some bacteria to remain active internally. Scientific research has shown that a 70%-75% alcohol solution is optimal for disinfection because it effectively coagulates proteins while also penetrating bacterial cell walls, which ensures a more thorough kill.
