Why do our soaps say 72% oil?

Did you know that?

Why does it say 72% oil on our soaps? What does this mean?

In 1906, the chemist François Merklen, who owned a soap factory in the region, set the percentage of vegetable oil in Marseille soaps at 72%, supplemented by soda and water.

He participates in a draft law on the repression of fraud in the soap trade. In 1928, the Court of Appeal of Aix-en-Provence confirms this composition of the Savon de Marseille to defend the reputation of the Savon de Marseille and to fight against counterfeits.

In short: this is the guarantee of a minimum vegetable fat content of 72% in the total composition of the soap.

In order to identify or recognize a real Marseille soap it must meet 3 criteria defined in the specifications adopted by the Union of Marseille Soap Professionals:

1- Soap must be made by a hot saponification process called the Marseilles process,

2- It must be made in the Bouches-du-Rhône department, the historical birthplace of Marseille soap,

3- The raw materials are all vegetable (72% of which are vegetable oils). No perfumes, colouring agents, preservatives, animal fats or additives are allowed in traditional Marseille Soap.
