|Our castile soap is made with sunflower and coconut oil and contains no harsh foaming ingredients. Castile soaps are the mildest and most moisturising of all soap bases - gentle enough to use on baby skin. Castile soap is detergent free so it will not produce a lot of sudsy lather. It is a great alternative to the more commonly used synthetic petroleum based soap products or those containing palm oil. Castile soap is labelled potassium oleate and potassium cocoate in our products and you can find it in our Clay Cleanser and Jojoba Cleanser.
