Its hydrophilic (water-loving) carboxylate group (-CO 2) interacts with water molecules via ion-dipole interactions and hydrogen bonding. The hydrocarbon chains are attracted to each other by dispersion forces and cluster together forming structures called micelles. Through this process, the soap interacts with the germs and makes them literally fall off whatever they are attached to.
