How is goat’s milk soap made?
But you can’t make soap from milk alone. Other ingredients could include natural oils from seeds, nuts, and vegetables, such as soybeans or coconuts. Soap has two main ingredients; lye and fat. When lye combines with a fat, chemical interaction hardens the oils, creating a bar of hard soap. When our great-grandmothers made their all natural soap, they used wood ashes and lard: the ashes were soaked in water, which leached out lye. Cooking lard with lye created soap. Original lye soaps were unscented and very harsh. They were also used for scrubbing laundry and floors, so their harshness helped pioneers get their clothes and homes—as well as their families—clean.
