This is what it says in her book: START WITH A BASE SOAP The criteria for selecting a base soap for hand milling are that the soap be white, unscented, and not a detergent. Unscented, hypo-allergenic soaps, such as baby soaps and pure vegetable soaps, are the best performers in hand-milled soap recipes. They may be harder to find in grocery stores, but they are readily available in drug stores and health food stores. When you shop for soap, you'll find detergent bars that are labeled "beauty bars," "deodorant bars," or "family cleansing bars." The word "soap" does not appear anywhere on the package. The recipes in this book don't use deodorant bars or family cleansing bars because they contain fragrances and color. Beauty bars are available without scent and color, but if you use beauty bars in your soapmaking you are including the additives, such as fillers, builders, and binders, that are present in them. Unscented beauty bars can be used for facial scrubs- they are not remelted, so the moisturizing cream they contain is beneficial. When making hand-milled soaps best results are obtained when using actual soap. Sorry this is so long. This probably makes sense to you great soapmakers out there, but I'm confused as to what soap I should use. (I've been reading alot and haven't made any soap yet.) Can anyone help? Thanks, Janet
