Castile soap is a very basic, versatile soap that can be used for cleaning nearly anything. It is simultaneously gentle and powerful—good for face wash, multi-purpose cleaner...and so much more! One of the most popular uses is as a foaming hand soap. Just combine 1 part castile soap with 3 parts water in a foaming soap dispenser. For a scented version, add a few drops of essential oils and gently shake or stir to combine. Our liquid castile soap is manufactured by Housebrand in Springfield, Missouri.
