Cold-saponified soaps :

Saponification is a chemical reaction resulting from the combination of a greasy base (vegetable oils, butters) and caustic soda or potash. The result of this reaction is glycerin and glycerol (soap).

In cold saponification, butters and waxes are gently heated to melt them. This gentle, ecological, no-cooking process preserves the properties of the ingredients, preserves the different qualities of the fats used, and produces soaps rich in glycerine (an emollient and protective agent, and an active moistrurizer), resulting in a product with unique benefits for the skin.
