For our soap sponge recipe, we have included the Clear Transparent Melt & Pour Soap Base. It is completely free from SLS (sodium lauryl sulphate), a foaming agent typically included in many commercial brands, which can be harsh and irritating on the skin. The base also offers fantastic moisturising properties that can create a soothing lather and foaming for your skin. Another advantage of using a transparent base is that it doesn’t cover up the original sponge colour and if you decide to add your own colours, they will also shine through with more clarity. Of course, the melt and pour soap base you use for your recipe is entirely up to you. There is no right or wrong option, only the one that works best for you. But if you want to minimise your exposure to any unnecessary chemicals and enjoy a soap sponge that produces a wonderful foam and lather, then this is well worth considering.
