A Versatile Black Soap for Cleaning the Home 

One of the defining characteristics of Savon Noir is its range of applications. 

Used across French homes for generations, it is suitable for: 

  • Cleaning floors and surfaces  
  • Degreasing kitchens and ovens  
  • Treating laundry stains  
  • General household washing  

Due to its concentration, it can be diluted depending on the task, making it both economical and long-lasting. 

This versatility reflects its origin as a functional soap, designed for use across the home rather than a single purpose. 

  • Choosing a Black Liquid Soap

    Black liquid soaps are traditionally produced using different vegetable oils, each giving the soap slightly different characteristics.

    Olive Oil

    The most traditional Marseille-style black soap. Strong degreasing power and widely used for kitchens, surfaces and outdoor cleaning.

    Olive Oil & Lavender

    The same olive-oil cleaning performance with the addition of natural lavender essential oil for a light herbal fragrance.

    Almond & Linseed Oils

    A slightly milder black soap traditionally valued for floor washing and general household cleaning.

    Almond, Linseed & Lavender

    A gentle household cleaning soap combining almond and linseed oils with lavender essential oil.

    Aleppo (Olive & Laurel Oils)

    Inspired by the Aleppo soap tradition, combining olive oil with laurel oil for a distinctive herbal character.

  • The Power of Soap

    Black soap cleans in the same way all traditional soaps do — by dissolving oils and lifting dirt so it can be rinsed away with water.

    Because it is a concentrated vegetable-oil soap rather than a synthetic detergent, its effectiveness comes from the natural chemistry of soap itself.

    Diluted in warm water it becomes a powerful but simple cleaning solution suitable for many surfaces throughout the home.

  • Fewer Products, Simpler Cleaning

    For many households Savon Noir replaces a cupboard full of specialised cleaning products.

    A small amount diluted in warm water can be used for everyday cleaning, while the concentrated soap can be applied directly to tackle grease, heavy dirt or stubborn stains.

    This simplicity — one traditional soap used in many ways — is the reason black soap remains widely used in homes across France today.
