This range of Melt and Pour Soap Bases are manufactured for us by SFIC, experts with over 45 years experience in their field. Free of SLS and the other ingredients you've told us you would rather avoid, and no big, unmanageable drums! All sizes and varieties come in logs, whether purchasing in wholesale and bulk, or smaller crafter sizes. Easier to handle, more manageable to ship to you. And yes, as always, we've crafted and washed with every single variety to trial it.
