True castille soap is 100% olive oil. That is exactly how we make this soap. Perfect for delicate skin (like babies and those with allergies), this soap is made with 100% extra virgin olive oil. There are no fragrances or additives. It does lather a bit differently than our other formulas but it will give you the most gentle soap available. 4oz

Ingredients: Extra Virgin Olive oil, sodium hydroxide, water...that's it!
