Käsidesinfektioita
Käsidesinfektioita, commonly known as hand sanitizers, are liquid, gel, or foam preparations that are used to kill germs and microorganisms on the skin. They are particularly useful when soap and water are not readily available for handwashing. The primary active ingredients in most hand sanitizers are alcohol-based, typically ethanol or isopropanol, at concentrations of at least 60%. These alcohol-based sanitizers work by denaturing proteins and disrupting cell membranes of microorganisms. Non-alcohol-based sanitizers also exist, often using ingredients like benzalkonium chloride, though they are generally considered less effective against a broad spectrum of pathogens compared to alcohol-based versions.
The effectiveness of hand sanitizers depends on several factors, including the concentration of the active ingredient,
