Marseille soap laundry liquid 1L (white)

A 1 litre bottle of pure vegetable oil liquid soap for hand or machine washing of delicate fabrics. From Salon-de-Provence where they have been made using the Marseille method since 1900. Batch processed in large cauldrons heated to 120°C for ten days allowing for a slow and thorough saponification of lye and oil, after which the curds are washed in both fresh and salted water to remove any excess sodium hydroxide or other trace impurities. Use 100ml either in a dosing ball, or the drawer of the machine.
