In chemistry, a soap is a salt of a fatty acid. Household uses for soaps include washing, bathing, and other types of housekeeping, where soaps act as surfactants, emulsifying oils to enable them to be carried away by water. In industry, they are used as thickeners, components of some lubricants, and precursors to catalysts.
I've been asked how to make soap over and over. Soap making is my number one passion. If I have a day to do nothing, I'll just make soap all day. Today I show you how I do it. In 1994 I came across a book on soap making and thought, "Well, gee, it can't be too hard."
