The short answer is NO! Lye is an alkali solution that creates soap when reacting with oils (fat). All soap is made with lye, but there's no lye on the final product that you receive in your home because all of it reacted with the highly nutritious plant-based oils to form soap.Our soaps are handmade using the cold-process method, which means that we free-formulate our soaps according to the result we would like to achieve from the final bar.
