The use of castile soap is an amazingly versatile vegetable-based soap that’s made free of animal fats and synthetic ingredients. This natural, nontoxic, biodegradable soap is available in bar or liquid form.
Castile soap was made in the Mediterranean area before its use spread to Europe. Traditionally, castile soap was made of olive oil. It gets its name from the Castile region of Spain.
 
These days, the soap is also made with coconut, castor, or hemp oils. Sometimes it’s made with avocado, walnut, and almond oils as well. These oils give the soap its lathering, moisturizing, and cleansing properties.
 
Castile soap is an exciting product since it’s not only environmentally friendly but also incredibly useful and effective for certain purposes. You can use it on your body, to clean your house, and even on pets.
