Understanding Soap and Its Mechanism
Soap works primarily by acting as an emulsifier, which helps lift dirt and bacteria from surfaces like skin. Traditional soap consists of a mixture that binds to both water and greasy substances, allowing dirt to be washed away effectively. Throughout history, the composition of soap has evolved, with modern formulations often emphasizing comfort and ease of use to encourage frequent handwashing. This mechanical action of soap, rather than its antimicrobial properties, is central to its effectiveness in maintaining hygiene.
