Explanation:
Detailed explanation-1: -When used for cleaning, soap solubilizes particles and grime, which can then be separated from the article being cleaned. In hand washing, as a surfactant, when lathered with a little water, soap kills microorganisms by disorganizing their membrane lipid bilayer and denaturing their proteins.
Detailed explanation-2: -Detergents have a hydrophobic tail (typically a long carbon chain), and a hydrophilic head (typically an ionic group). Detergents are able to remove oils and stains because the hydrophobic end of the molecule can bind to the stain, while the hydrophilic end can bind to water.
