Artisans make Marseille soaps using vegetable oils such as olive oil and copra oil. These oils are heated in large cauldrons. After mixing with soda, the stirring lasts several days. The mixture is poured into molds to dry for several weeks to several months. This process develops the hardness and longevity of the soaps. They have gentle and effective cleansing properties. They are used as body soaps, shampoos, and household cleaners. Marseille soaps are gentle on the skin and environmentally friendly, biodegradable, and free from dyes and artificial fragrances.
