Furthermore, esters have sweet fruit smells and with low molecular mass. Esters are used in the manufacturing of soap, the hydrolysis of fats or oils (triglyceride ester) in the presence of a strong alkali, such as (NaOH) or (KOH) to produce glycerol and (sodium or potassium salt of fatty acid) is known as saponification process which is the main reaction in the manufacture of soap. The reaction is called a saponification from the Latin sapo which means soap. Esters are sweet-smelling liquids used to flavor foods and sweets. 2. There are various uses of esters.
