Saponification
Saponification Step One & Saponification Step Two . To convert triglycerides to soaps, a one-step or two-step saponification process can be used. The preceding examples are of a one-step saponification process in which triglycerides split from the ester bond to release glycerol and soaps when treated with a strong base (i.e. …

Saponification Definition and Reaction
Saponification is the name of the chemical reaction that produces soap. In the process, animal or vegetable fat is converted into soap (a fatty acid) and alcohol. The reaction requires a solution of an alkali (e.g., sodium hydroxide or potassium hydroxide) in water and also heat. The reaction is used commercially to make soap, lubricants, and ...

Soaps are the salts of (mainly) saturated and unsaturated fatty acids having carbon number C10 to C18. The source of the fatty acids is always a blend of natural triglyceride oils. However, relatively few manufacturers make soap by neutralizing a blend of fatty acids. Most create soap directly from the blend of oils.
