Pure Olive Soap - Ultra Gentle / Delicate and Dry Skin Our olive soap with 8% superfat is ultra gentle for all skin types. It is composed solely of organic olive oil, known for its moisturizing, nourishing, and softening properties. Our olive soap is cold saponified, crafted artisanally at the Senza workshop in a comprehensive ecological approach: fewer kilometers, less energy, more organic. Designed without fragrance and allergens, it is suitable for the whole family. Our olive soap, like all products in the Senza range, holds the Nature & Progress 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 (minimum 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%.
