Soap consists of sodium or potassium salts of fatty acids and is obtained by reacting common oils or fats with a strong alkaline in a process known as saponification. Soap is derived from either vegetable or animal fats. Handmade soap differs from industrial soap in that, usually, an excess of fat is sometimes used to consume the alkali (super fatting), and in that the glycerin is not removed, leaving a naturally moisturizing soap and not pure detergent. Mrs. Anita Thomas, my grateful thanks to her for the able teaching and guidance. 11. Soaps are created by the chemical reaction of a jetty acid with on alkali metal hydroxide.
