However, according to Pliny the Elder (23 -79 AD), hard soap was invented by the Gauls who made it from ashes, tallow and lard or inedible oils. It was then mainly used to wash hair.
After that, the use of soap became more and more common in Europe, first for the wealthy and then later for the common people.
La légende du mont Sapo
Legend has it that soap originated from Mount Sapo, a fictitious mountain on the outskirts of Rome.
The story explains that the Romans used to make animal sacrifices on its slopes. Then, the ashes from the wood fires mixed with the fat of the killed animals forming a primitive soapy material. This liquid flowed into a nearby stream, where women used to wash clothes, and they noticed that there the stains were easier to clean.
Cette légende expliquerait l’origine latine du mot savon, sapo, du nom de cette montagne. Cependant, elle n’a jamais été prouvée même si elle apparaît souvent dans des récits et d’autres sources.
Les types de savons
Il existe plusieurs sortes de savon avec des utilisations variées : pour le corps, pour le linge, pour la maison… mais ils ont un but commun de retirer les taches et de nettoyer. Un savon peut prendre plusieurs formes différentes et garder son efficacité.
As a bar of soap
In powder form for laundry
In liquid solutions such as shower gel, dishwashing liquid or hand soap.
However, it is their composition and not their form that really differentiates one soap from another.
Le savon médicinal
Medicinal soap is another way to take advantage of the active ingredients found in medicinal plants. It is made with oil extracted from plants with healing properties.
Le savon d’Alep
Aleppo soap is a very ancient soap that was created several millennia ago. It is made from vegetable oil and soda. Usually the oil used is either olive oil, berry oil or bay leaf oil.
Le savon noir
The raw material of black soap is resin. This ingredient gives it stronger degreasing capacities than other soaps.
Le savon de Marseille
The current Marseille soap is made from palm oil and olives mixed with soda.
Contrary to beliefs, Marseille soap does not originate from the city of the same name. It is Gallipoli, an Italian city along the Ionian Sea which was probably the origin of this soap so well known. Gallipoli is a town where a very good quality olive oil is made. The inhabitants of Gallipoli had the idea of adding soda to the remains of pressed olives to make white soaps.
It was only later that Marseille became the main producer of this soap.
