In soap making, the term “bastille,” commonly refers to cold process soap made with at least 70% olive oil. Olive oil is extremely gentle, making it the perfect oil for delicate or sensitive skin. This Buttermilk Bastille Baby Bar is comprised of olive oil and a small amount of coconut oil for cleansing properties. This recipe also uses luxurious and moisturizing buttermilk. Carrot puree which is known for its antioxidant properties, is added at trace to give the soap a soft natural color. All these skin-loving and gentle ingredients make this bar great for babies and young children.
