How to Make Savon de Marseille Laundry Soap with Bicarbonate of Soda

This article explains how to make Savon de Marseille laundry soap with bicarbonate of soda. This is not to be confused with our other article How to Make Marseille Soap Laundry Detergent with Soda Crystals so I will start by explaining the difference between the two:

  • Bicarbonate of Soda is heated to 100°c to create Soda Crystals. Therefore, Soda Crystals are much more intense and potent.


By the way, this is the recipe that Sophie and I use to create our laundry soap, and it works exceptionally well 🙂


 Ingredients Needed

To make a litre and a half of laundry soap, you will need the following items:

  • 40g of white Savon de Marseille, grated or in shavings

  • 3 tablespoons of bicarbonate soda

  • 2 tablespoons of white vinegar

  • 2 litres of water

  • 10 drops of essential oil (orange, lavender, lemon, tea tree, etc.)


How to Make Savon de Marseille Laundry Soap

  • Throw the soap shavings and the bicarbonate soda in a litre of very hot, but not boiling, water.
  • Stir the mixture until there are no lumps and before taking off the heat.
  • Leave the mixture to cool for about 2 hours.
  • Then add another litre of warm water along with the white vinegar.
  • Thoroughly rinse out an old detergent bottle.
  • With the help of a funnel, pour everything into the bottle.
  • Add a few drops of your favourite essential oil to perfume the soap.
  • Use about 100ml of your new Savon de Marseille laundry soap per wash.


Benefits of Using Savon de Marseille Laundry Soap

So why go to all the trouble of creating this laundry soap? First of all, obviously, it is natural, but several things will happen during the washing cycle:

  • The bicarbonate soda preserves the colours in your fabrics.
  • Savon de Marseille thoroughly cleans your laundry.
  • The white vinegar will descale your washing machine.



Here are a couple of extra tips for you:

  • For a quick wash, pour 100ml of washing detergent into a ball at the centre of your laundry.
  • Add an additional two tablespoons of bicarbonate soda and, as a result, see further whitening of your laundry,
  • Add a half glass of white vinegar in the softener tray to give your laundry some extra softness.
