The melt and pour soap method is the safest to begin with, as the basic principle is melting a soap base and pouring it into a mold. Working with melt and pour soap means the “saponification process” – the process that converts lye or fats into soap – has already been completed and has yielded a base that is ready to use and customize.
Melt and pour soap contains a high percentage of glycerin, which means it has a highly moisturizing quality that makes it gentler on skin than store-bought soaps. Glycerin is a component of fat or oil and is a natural byproduct of the saponification process. When exposed to humidity, melt and pour soap tends to “sweat,” because the glycerin attracts moisture from the air, so they must be kept as dry as possible on well-draining surfaces.
