Castile soap is a versatile, biodegradable soap made from vegetable oils, primarily olive oil. Originating from the Castile region of Spain, it is known for its gentle cleansing properties and is suitable for various skin types. This soap is often used for personal care, household cleaning, and even as a pet shampoo. Unlike traditional soaps that may contain animal fats, Castile soap is vegan-friendly and free from synthetic additives, making it a popular choice for those seeking natural and eco-friendly products.
