Castille Soap - Unscented"Castile" soap used to be made from 100% olive oil; it was mild and soft and even though our parents and grandparents liked it for its smoothness and especially for its mildness when compared to traditional lye soap, today s generations have different expectations of what soap should be like and what it should feel like, and pure Castile soap (described by many as slimy ) wouldn t fit the bill.
