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.
Best Answer: Soaps are the sodium or potassium salts of fatty acids. The tails of the soap molecules are chemically equivalent to fat or oil, i.e. they are both hydrophobic and non-polar. Therefore, soap can dissolve in oil. The heads of soap molecules, however, are hydrophilic and ionic in character. This allows them to dissolve in ionic and polar substances, e.g. water. When oily dirt is immersed in a soap solution, the tails attach themselves to the oil.
