Black soap

Be careful not to confuse the two types of black soap! Although they may resemble each other in colour and texture, they do not have the same composition. The black soap for body care is made from a paste of olives (crushed and macerated) in salt and potash (potassium olivate). It comes in the form of a soft, darker or lighter brown paste. The household liquid black soapIt is composed of potash and any type of fat, such as olive oil, linseed oil, glycerine, etc.

To recognise a good soap and know whether it is of good quality, the first thing to do is to check its appearance. Visit cosmetic black soapGood quality oil should have a compact texture. Its colour should be darker or lighter, depending on the oil used. As for its smell, it must not be too strong! Many additives can be used: antibacterial agents, essential oils, moisturising agents, etc.

MANUFACTURING

Like all soaps, black soap is obtained by saponification. The materials needed to make black soap are palm oil and potash (KOH). A mixture of palm oil and oils macerated in salt and potash is used. The formulas vary but the basic elements are always the same. It is therefore an entirely natural substance.

The making black soap is the result of a slow, non-reversible transformation called hydrolysis or saponification. What is saponification? In a nutshell, it's a chemical reaction similar to neutralisation, but where the acid is an organic fat and the products are a non-neutral salt and glycerine: base + fat (acid) = soap + glycerine. This chemical transformation, which takes place at a temperature of between 80 and 100°C, takes place in several phases: emulsion, self-catalysis, then slow saponification. At the end of this transformation, the ingredients used have disappeared.

This saponification process produces a mixture of potassium carboxylates, which make up the soap, and glycerol or glycerine (a by-product of this reaction). The black soap obtained is a perfectly smooth, oily, vegetable scrubbing paste. Its consistency resembles honey. Its colour varies from green, dark brown to black. This depends on the oil used and the manufacturer.
