Classic soap is a mixture of sodium (solid soap bars) or potassium (liquid hand soap) salts of fatty acids, produced by saponification of animal fat (tallow) or vegetable oil. Today, many additional compounds are usually added -- antiseptics, moisturizers, etc, but the base is the same.
To understand how antiseptic (i.e. antibacterial) soaps work, well first look at how soap functions in general. Most molecules are either water-loving (hydrophilic) or water-hating (hydrophobic). The reason water alone doesnt clean off dirt and germs is because those molecules are mostly hydrophobic.oap is made up of fatty acids (derived from oils or fats) and a base (like sodium hydroxide salt). The soap molecules have hydrophobic (fatty acid chain) and hydrophilic (salt) ends. This combination allows soap molecules to suspend the oils, dirt and germs that are washed away when you soap up.
