Cold soap making process

First discovered thousands of years ago, soap has appeared in varying forms over time, in the Mediterranean. It is formed from the natural or provoked chemical reaction known as the saponification of fatty substances.

Cold soap making: the process

Amongst the various soap making processes, cold soap making is a natural method of soap production.

It consists of a mix of fatty substances and a strong base, usually sodium hydroxide (lye or caustic soda) for solid soaps and potassium hydroxide (potash) for liquid soaps. The fatty substance (vegetable oil, animal oil or butter) undergoes an irreversible transformation on contact with the lye or potash.

This chemical reaction, called alkaline hydrolysis, is complete, that is to say, it continues until one of the ingredients is completely dissolved, and it takes place by heating the ingredients together to a temperature of 40°C, hence the name cold soap making.

The mixture obtained is poured into a mould. After around 24 hours, the “gel” stage produces partially or totally solidified soap and allows it to move on to the cutting stage. The soap is then dried at room temperature for four to eight weeks.

 

The advantages of cold soap making

Cold soap making doesn’t lead to the discharge of glycerol. It allows the soap to preserve its natural vegetable glycerine. This means that it is what is known as a “superfatted” soap: it maintains all of the moisturising and nutritional qualities of the fatty substance it contains.

As well as being easy to make, it is also very cheap to produce and generates neither waste nor residue. The vast number of different vegetable and animal oils available makes it possible to create a wide variety of soaps.

The addition of specific ingredients to the “trace” product, such as essential oils, colourants, etc., allow for the creation of soaps with very different cosmetic, aromatic and aesthetic properties.
