It is a DE-estherfication (hydrolysis or saponification of triglicerides, eg. glycerol-tri-Oleate) in alkaline, so it is not the acid that is freed from the esther, but its conjugated base of that fatty acid (eg. Oleic acid) which forms a (sodium or potassium) salt with the (most commonly used) sodium (or potassium) hydroxide or carbonate.

In saponification, the solid product (eg. Sodium Oleate) is specifically called a soap!

Keeping this as simple as possible, keep in mind water is a polar molecule with a slightly negative charge at the oxygen and slightly positive charge at the hydrogens. When the soap is being held in solution the charges of the water molecules are essentially holding it there through their attraction. However when we add an ion, such as those released when the ionic bonds between NaCl (salt) are broken these have a stronger attraction to the polar ends of the water molecule than the soap does. This causes the water to sort of redirect its attention to the Na+ and Cl- ions causing them to "drop" the soap molecules.

The process is called "salt out" and it is done to force the soap to precipitate out or to coagulate.

The product of saponification is a salt because of the components in the process. Since it hydrolyzes alkaloid molecules or long ester chains, a salt is all that is left.

Is soap made from salts?

NO, THERE IS NO SALT IN SOAP!!! ---------------------------------------------------- Sodium Chloride (NaCl) is often called Salt or Table Salt. However, technically it is only one type of salt. In Chemistry, a salt is any ionically bonded compound. Lye Soap is a type of soap formed by an ionic bond between Sodium (Na+) and the conjugate base of a fatty acid (ROO-) ROO-Na+ And thus, Lye Soap IS A SALT. Salts will dissociate into their ionic constituents in water. Soap is not required for that step.


How does saponification relate to organic chemistry?

The preparation of soap is called as saponification. When an ester reacts with a sodium salt of a carboxylic acid in the presence of a lye, it forms soap. All the reactants and products are organic.
