What is this Soap-making Process called Saponification?
Saponification is a cold process method of making soap where a vegetable oil or animal fat is mixed with a strong alkali. The result of this reaction is soap and glycerin. Unlike in mass production of soaps, handmade soap is made by letting the ingredients take the time they need to interact with each other. The soap provides the cleaning agent; glycerin is known for its skin softening properties. It attracts and retains moisture.
Handmade soap is usually more expensive because of the presence of glycerin. In some cases they are extracted and sold as an ingredient for skin products that are part of the high-end cosmetics market. In its place are added ingredients such as parabens and sodium laurel sulphate; ingredients that are not very friendly to the skin. It is wise to check the label of soaps that you buy. It can make a difference in the health and look of your skin.
