Coffee Soap - Radiance Boost / Exfoliant Our coffee soap with 8% superfat exfoliates and refines your skin's texture. It is composed solely of organic olive oil, organic plum kernel oil, and upcycled organic coffee grounds. We collect the organic coffee grounds from the committed brand Esperanza every week from our Parisian partners. The plum kernel oil nourishes the skin and soothes the exfoliating action of the coffee grains. Our coffee soap is cold saponified, handcrafted at the Senza workshop in a comprehensive ecological approach: fewer kilometers, less energy, more organic. Our coffee soap, like all products in the Senza range, has the Nature & Progrès label, the strictest in cosmetics. What is cold saponification (CS)? Saponification involves mixing a fat (oil) with lye to trigger a chemical reaction. Unlike hot saponification where the mixture is heated to speed up the reaction, cold saponification allows the mixture to saponify over time (at least 4 weeks). At Senza, this is the process we use. In addition to avoiding the use of energy for heating, it allows us to preserve the properties of each ingredient used. What is a superfat? The addition of excess vegetable oils compared to the lye at the end of the cold saponification process is called "superfat." This excess volume will not be saponified, and the final formula, enriched with nourishing superfatting agents, will be gentler on the skin. At Senza, all our soaps have a superfat content between 8% and 9%.
