Soap is obtained from glyceryl ester of fatty acid by the process of saponification.

Saponification, which occurs in acidic or necessary circumstances, is the hydrolysis of an ester to produce an alcohol and the salt of a carboxylic acid. The process of creating soap when a metallic alkali (base) reacts with fat or oil is known as saponification.

As a result, the process of saponification is used to turn glyceryl ester of fatty acid into soap.
