Pébéo Lavender Scented Liquid Soap is made the old-fashioned way, using the method from Marseille, cooked in a cauldron, made from vegetable oils and potash. It does not contain animal fat or synthetic surfactant (cleansing substance), nor tetrasodium EDTA and BHT (chemical preservatives). Its formula is kind on both the skin and the environment, as it is biodegradable and is stored in a refillable and recyclable bottle.
