If you want to make traditional cold process soap, hot process soap, or even transparent soap, you have to use sodium hydroxide, also known as lye (NaOH). Sodium hydroxide is used when you want to make a solid, bar soap, whereas potassium hydroxide is used to make natural liquid soaps and shampoo.

Sodium Hydroxide or “lye” is the catalyst used to convert oil molecules to soap molecules. The result of combining oil and “lye” is known as saponification. Every oil and butter has its own saponification value or “sap value”.

The amount of lye needed to convert oil to soap, is based on the sap value of the oil you are using.
