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.
Fats and oils are composed of triglycerides; three molecules of fatty acids attach to a single molecule of glycerol. The alkaline solution, which is often called lye (although the term lye soap refers almost exclusively to soaps made with sodium hydroxide), brings about a chemical reaction known as saponification.he glycerin, a useful by-product, can remain in the soap product as a softening agent, or be isolated for other uses. Soaps are key components of most lubricating greases, which are usually emulsions of calcium soap or lithium soap and mineral oil.
