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.
Sodium soaps are hard soaps. When the alkali is potassium hydroxide, a potassium soap is formed. Potassium soaps are softer and are found in some liquid hand soaps and shaving creams. The carboxylate end of the soap molecule is attracted to water. It is called the hydrophilic (water-loving) end.
