How does soap effectively eliminate pathogens from hands?

Soap effectively eliminates pathogens from hands primarily through the action of friction generated when rubbing the soap and water together. This mechanical action helps to lift and dislodge dirt, grease, and microorganisms from the skin. Soap molecules have a unique structure that allows them to break down oils and fats, which can harbor pathogens. When you create bubbles by lathering soap, these bubbles encapsulate pathogens and dirt particles within them. The friction assists in dislodging these contaminants from the skin, making it easier to rinse them away.

The hydrophilic (water-attracting) and hydrophobic (water-repelling) ends of soap molecules work together to encapsulate pathogens, which is essential for effectively cleaning the hands. This combination of mechanical action and the chemical properties of the soap ensures that pathogens are effectively removed, promoting better hygiene.
