Aleppo soap is considered a medicinal soap with beneficial properties for problem skin. This recipe contains 5% unsaponified fats, has a specific, smoky scent.
The original soap, produced in Syria, was originally made in hot water. This recipe meets the standard of at least 20% laurel oil, except that the method of production is cold process.

1. Have all utensils and equipment ready on the workbench, within easy reach. Carry out the necessary substance weighings from the recipe.

2. Add distilled water to a heat-resistant container, over which, little by little, add the Sodium Hydroxide and stir slowly, carefully, until it is completely dissolved and the solution becomes transparent. Allow the solution to cool to about 40°C.

3. Heat the oils in another heat-resistant vessel on a sea bath to approx. 40°C.

4. Transfer the oils to a container with a volume of more than 1000 ml, or use the vessel in which they were heated if it is large enough. Slowly pour the sodium hydroxide solution over the oils. Both should be of similar temperature.
Place the blender in the bowl and blend until the mixture is the consistency of pudding.

5. Transfer the mixture to the chosen mould. The resulting quantity can be poured into 8 rectangular moulds (so two moulds are needed) or a 1 kg block mould. Both can be found in the links below.
Spray the surface of the soap with alcohol to prevent the formation of sodium carbonate.

6. Cover the soap with foil and leave for 2 days in a cool place. Once the soap has hardened, remove from the mould and cut as desired. To remove from the mould if it is still soft, refrigerate for 2-3 hours.

7. The soap is then left to mature in a well-ventilated space, on shelves or in covered boxes (but not closed to allow air circulation). Maturation takes a minimum of 4 weeks from the date of production, during which time the soap is not used as it is still reactive.
For best results, this type of soap should be left to mature for 6-12 months.
