Saponification in the Soap Making Process

Saponification is at the heart of soap-making. It is the chemical reaction in which the building blocks of fats and oils (triglycerides) react with lye to form soap. Saponification literally means "turning into soap" from the root word, sapo, which is Latin for soap. The products of the saponification reaction are glycerin and soap.

Now to explain, chemically, how soap works to clean things. Fats mixed with strong bases are hydrolyzed into fatty acids. Fatty acids have the very useful property of having one end that mixes well with water (it is hydrophilic, or "water-loving") and another end that mixes well with oils and fats (it is hydrophobic, or "water-hating"). The part that mixes well with water is the "acid" part.
