At Marché du Plateau, we celebrate the art of cold saponification, a process that transforms fats – vegetable oils and butters – into soap through a delicate chemical reaction. This alchemical journey takes place at low temperatures, generally below 30°C, to preserve the beneficial properties of the ingredients used.

At the heart of this transformation lies the« trace » stage, a crucial moment when the mixture acquires the texture of a soap paste of varying thickness. For the artisan soap-maker, this stage is fundamental, as it enables him to monitor the consistency of the soap and ensure its optimum quality.

This is also when we add the other natural ingredients that make our cold-saponified soaps so rich. Essential oils for their aromatic and therapeutic properties, mineral or plant colorants for a touch of natural color, plant powders for their benefits to the skin, and even honey for its moisturizing and soothing virtues.

Once the soap paste has reached the desired consistency, it is carefully poured into a mold, then placed in a cool place to harden, usually for 24 to 48 hours. This is followed by the« cure« , a period of rest in a dry, airy place for at least 4 weeks. Curing is an essential phase that finalizes saponification, resulting in a soap that is gentler, longer-lasting and more respectful of your skin.
