The manufacture of an authentic traditional Marseille soap meets different criteria of geographical origin (the Marseille region), manufacturing process (in a cauldron and in five stages), and composition (based on exclusively vegetable oils and without additive: preservative, coloring, perfume, animal fat). The association of UPSM (Union of Professionals of Marseille Soap) ensures the protection and promotion of the label. It has also set up a logo guaranteeing manufacturing in accordance with the know-how established by an edict of Colbert in the 17th century.
