For most of the batches of cold process soap I have used distilled water. I know that you can use other types of liquids from goats milk to carrot juice but I have never tried it before. According to The Soap Queen, one of the most popular types of alternatives liquids for cold process soap is alcoholic beverages. This category includes beer,wine and champagne. Since these liquids contain sugar, they would give your soap a stable and fluffy later. They can also give the soap color. Some of these types of beverages contain beneficial properties like anti-oxidents but it is debatable whether these properties make it through the saponification process. Want to learn more? Then read the post titled How to Use Alcoholic Beverages in Cold Process Soap which appears on The Soap Queen's site.
I have a B.A. in Mass Communication and took my first melt and pour soapmaking class in 2002. Since then I got hooked making my own bath and products. I have taken various courses in Soapmaking (Melt & Pour, Cold Process, Hot Process), lotion making (lotions, creams, lotion sticks), bath products (bath salts, body scrubs), body products (lip balm, body butters, body balms, whipped butters) and more. Most of all of my classes were taught by Lori Nova of The Nova Studio in Point Richmond, Ca. I have taught courses since 2004 at various locations. I have worked as an Event Coordinator at Michaels Redwood City.
