Soap Production_1Soap production occurs between a fat molecule and lye or Sodium Hydroxide/Potassium Hydroxide (NaOH/KOH). This little tutorial looks at a triglyceride molecule and 3 NaOH molecules. What other fats are there and what would their reactions look like? So the reaction would be written like this
This is the chemical reaction involving 1 triglyceride molecule and 3 NaOH molecules. In order to completely break apart 1 triglyceride molecule we need 3 NaOH or 3 KOH molecules. This becomes important when you begin to calculate how much lye you need for the oils you are using. The reactants are your triglyceride and NaOH and the products are your 3 Sodium Carboxylates and the 1 glycerol (glycerin) molecule.
Here it is explained in a bit more detail to where you can follow along with where the molecules start and where they end up by looking at the colors of the oxygens and carbons and sodium ions. By the way, a triglyceride is a chemical. It’s a fat which is also termed a chemical. Therefore, whenever anyone tries to tell you soap is not composed of chemicals you know they are blowing smoke up your arse. It’s an ORGANIC (or carbon containing) chemical but a chemical nonetheless just like NaOH or sodium hydroxide is a chemical.
