Castile soaps are a classic style defined by their simplicity and exceptional purity, traditionally made with 100% olive oil and renowned for their mildness and versatility.
Purpose and Formulation: True Castile soap originates from the Castile region of Spain and is historically defined by using only vegetable oils—specifically olive oil—as the saponified base, rather than animal fats. Modern interpretations may incorporate small amounts of other mild oils, but olive oil must remain the primary ingredient. Olive oil is rich in antioxidants and creates a gentle, creamy lather that is famously non-drying. Due to their simple, pure composition, Castile soaps are hypoallergenic and biodegradable, making them incredibly versatile. They are not only used for body cleansing but are also often diluted for use as an all-purpose household cleaner, laundry detergent, or even a gentle pet shampoo. The focus of Castile soap is on the natural, unadulterated quality of the primary oil, appealing to users seeking multi-purpose, gentle, and environmentally friendly cleaning solutions.
