Melt and pour soap base, It is soap that comes as a pre-made base, ready for you to add colours and fragrances. You can pour it into any mould or shape you can think of, and perfect to make soap sponges. Melt and pour soap base is the best choice for beginners and experienced soapers alike. Our opaque white soap base is Sodium Lauryl Sulphate (SLS) free, which helps this soap base to be more gentle on the skin. SLS is frequently used in shop bought soap and other cosmetics, but is best avoided if you ask us. This soap base is a true blank canvas, perfectly white and ready to take any colour or fragrance that you can think of.
