Black Marseille Soap: History, Production, Properties, and User Guide
What is black Marseille soap?
Rampal Latour Liquid Black Soap is a natural, multi-purpose cleaner, obtained by saponifying vegetable oils such as olive or linseed oil with potash. Unlike solid Marseille soap, which is more suitable for personal hygiene, black soap is distinguished by its liquid or gel consistency and its degreasing and versatile properties. It is biodegradable, hypoallergenic and safe for both skin and the environment.
For Italy and for my clients, I have chosen to directly import Rampal Latour products, a guarantee of Provençal tradition and quality. The best for skin, home, and the environment: I am proud to be an official reseller of this excellent brand.
A brief history: from the Mediterranean to Provence
The origins of black soap lie in the Mediterranean. In Morocco, it is known as "beldi" and has been used for centuries in hammams for cosmetic treatments. In Provence, on the other hand, black soap established itself as a variant of traditional Marseille soap, developed mainly for household cleaning and laundry.
Even today, historic soap factories like Rampal Latour keep this tradition alive, offering an authentic and high-quality product.
How it is produced
Black soap is produced through a three-phase artisanal process:
- Cooking vegetable oils (such as olive or linseed) in large vats.
- Adding potash (KOH) and water, which initiates saponification.
- Filtering and refining until a soap with a soft consistency and typical dark color is obtained.
The result is a liquid, concentrated, and natural detergent.

Black soap vs. classic Marseille soap
- Liquid black soap: potash-based, soft consistency. It is perfect for household cleaning, laundry, and gardening.
- Solid Marseille soap: soda-based, hard consistency. It is ideal for personal hygiene and as a neutral base for DIY detergents.

Liquid black soap is extremely versatile:
