Marseille soap (Savon de Marseille) is one of France's most enduring exports — a simple, effective soap that's been made in the port city of Marseille since the Middle Ages. With a recipe regulated by royal decree since 1688, authentic Marseille soap contains just four ingredients: olive oil (minimum 72%), water, sea salt, and soda ash.
Six hundred years later, this formula hasn't changed. And for good reason — it works.
A Brief History
Soap production in Marseille began in the 14th century, building on techniques brought from Aleppo by Crusaders. By the 17th century, Marseille had become Europe's soap capital, with dozens of factories producing soap for the entire continent.
In 1688, King Louis XIV issued the famous Edict of Colbert, which strictly regulated Marseille soap production: 72% olive oil, Louis XIV regulated recipe, Provence tradition. Any soap not meeting these standards could not use the Marseille name. While this regulation isn't legally enforced today, the best producers still follow it religiously.
What Makes Real Marseille Soap
- 72% olive oil: This isn't a marketing claim — it's the historical standard. Look for "72% huile d'olive" stamped on the soap.
- Cooked in cauldrons: Traditional Marseille soap is cooked for 10 days in large copper cauldrons, not mass-produced in factories.
- No animal fats: Authentic Marseille soap uses only vegetable oils.
- No synthetic additives: No fragrance, no colorants, no preservatives in the traditional formula. Scented versions use natural essential oils.
Benefits
- Hypoallergenic: The minimal ingredient list makes it ideal for sensitive and reactive skin
- Deeply moisturizing: 72% olive oil means your skin gets a generous dose of vitamin E, squalene, and oleic acid
- Versatile: Traditionally used for body, face, hair, laundry, and household cleaning
- Long-lasting: A single bar of Marseille soap outlasts liquid soap by weeks, making it economical and reducing packaging waste
- Eco-friendly: Fully biodegradable with minimal packaging
How to Spot Imitations
The term "Savon de Marseille" isn't legally protected, so many industrial soaps use the name. Real Marseille soap:
- Has a stamp reading "72% huile d'olive" or "Extra Pur"
- Lists only olive oil, water, sodium hydroxide (or sodium olivate), and salt
- Has an irregular, hand-cut appearance
- Comes in large blocks (traditionally sold by weight) or hand-cut bars
