Making Lye Soap – Saponification

Saponification is the chemical process of making soap that involves an exothermic reaction between lye (sodium hydroxide) and a fat (usually oils). What is commonly known as cold process soap making yields a glycerin-rich soap, which used to be referred to as lye soap. People may associate lye soap with something that is unpleasant to use because too much lye was used in the soap formula and lye (sodium hydroxide) remained in the bar of soap to irritate and burn the skin. Soap cannot be made without using lye. When made correctly, no lye will remain in the bar of soap.

Soap cannot be made without using lye but when done the right way, no lye will remain in the bar of soap.
