Make your own savon noir just like that used in the Hammans
What is Savon Noir?
This Black soap is mainly composed of olive oil and black olives. That's what gives it that dark colour. Moreover, its virtues reside mainly in its composition. Olive oil and olives are one of nature’s super hydrating and highly nourishing botanicals for the skin and hair. It is traditionally used in Hammans as a body, face and hair mask but it has excellent cleaning properties when used around the home, garden and DIY
Savon Noir can often be found as a smooth paste but it is more popular liquid form, the latter being the most available in supermarkets. However, as with most mass produced “soap” (detergents), the Savon Noir you can buy in the supermarkets often contain chemical additives that are extremely very harmful human health and the environment.
The natural method of fabrication is to crush and macerate the olives in salt and potash (alcaline) to extract their beneficial virtues. The Olive oil is then added to produce a glutenous like substance that is Savon Noir. Originally from southern Morocco, it is also called Beldi Soap.
Unlike other black soaps, made from linseed oil, this recipe is made entirely from olive oil and black olives
Traditionally, Potash (wood ash) is used to make Black Soap but the following recipe uses a mixture of Potassium Hydroxide (KOH) traditionally used to make liquid soap and Sodium Hydroxide (NaOH).
It is important to understand that the saponification indices of Potassium Hydroxide (KOH) are different from the saponification indices of Sodium Hydroxide (NaOH). If you are not familiar with the formula and method for calculating alkaline quantities in saponification, follow this recipe below or come learn how to formulate your own recipes in one of our classes.
Most Black Soap recipes require an artificial heat source such as a Slow Cooker but this recipe relies solely on the natural exothermic reaction of the saponification
Here's the recipe with 3% super-fat and unperfumed
- 500g of Olive Oil
- 75g black olives freshly crushed with pestle.
- A lye mixture of 17.00g of sodium hydroxide (NaOH) and 75.00g of Potassium Hydroxide (KOH)
- 179g of distilled water (To vary, you can replace the amount of water with a floral water such as rose, or other similar)
Finely dice, chop or grind the whole fresh black olives with a pestle
Weight out your Olive Oil quantity and place the diced black olives into the oil.Let it infused for 24 hours before straining and separating the olives from the oil. Some recipes infuse the oil and olives with coarse salt for 24 hours before adding the lye to obtain a black paste.
Prepare the lye solution of Potassium Hydroxide and Sodium Hydroxide by gradually integrating it into the pre-weighed water. Work in a well ventilated place and wear a mask, and gloves. Once the lye is well dissolved, add it to the macerate of olive oil and black olives.
Using an electric hand blender, blend until trace is achieved. As olive oil is an unsaturated fatty acid, it takes about 10 minutes to get trace. To avoid damaging your electric mixer, I recommend using it for 2 minutes, and then mixing it by hand for 2 minutes until you get the trace.
Add 24g (3%) of essential oils (if using) for a scented black soap
Pour into your mould, cover and let the soap batter cure for a minimum of 4 weeks during which time it will be come jelly like and slightly clear.
The image below is the savon noir made without using black crushed olives. The green colour of this jelly like substance comes from the olive oil
After the Cure
At the end of the cure period, you will obtain a perfect paste of black soap (if you’ve used black olives). Test the pH with your normal pH testing kit or implement - A pH of 7.5 is perfect !
Transfer the Savon Noir into a jar with a lid.
To use as a household cleaning product, a teaspoon of soap paste dissolved in 1 litre of water will bring sparkle and shine to everything you clean from glasses to tiles, baths, sinks, cookers and more !
Use it as a beauty aid by smoothing the paste over your face, body & hair like a mask. Relax then rince after about 10 minutes. Soft, supple skin.
