Cold Process Soap is a method of making soap that involves mixing oils and fats with a lye solution at room temperature. This process allows for the natural properties of the ingredients to be preserved, resulting in a gentle and moisturizing product. The chemical reaction, known as saponification, occurs as the lye interacts with the oils, creating soap and glycerin. One of the benefits of cold process soap is the ability to customize recipes with various oils, scents, and colors. This method typically requires a curing period of four to six weeks, during which the soap hardens and becomes milder for use.
