[e.g. Sodium Stearate]. Soaps are made from fats and oils, or their fatty acids, by treating them chemically with a strong alkali. Detergents are made up of concentrated acids which react with alkalis to form salts. These salts contain long - chain molecules with an ionic sulphonate group.

My question is should I included saponification value for stearic acid or treat this calculation as normal proportion: 284.4772 g/mol - 40 g/mol. 5% - x . Second option as I have mentioned is taking into account saponification value for stearic acid which is between 206 and 212, so let's say for calculation purpose we will take 209. ...

Saponification Definition and Reaction

Jan 08, 2020·Saponification is a process by which triglycerides are reacted with sodium or potassium hydroxide (lye) to produce glycerol and a fatty acid salt called "soap." The triglycerides are most often animal fats or vegetable oils. When sodium hydroxide is used, a hard soap is produced. Using potassium hydroxide results in a soft soap.
