One of the main benefits of cold process soap making is having complete control over ingredients. This is why we chose this process. Like all of our Scrubba products, we are very particular about what goes into them. Cold process soap has no added detergents, which strip the skin of its natural oils and can cause allergic reactions. Additional ingredients are also added to increase the skin loving benefits, like oats, kaolin and a bunch of other botanicals. Depending on the ingredients you use, cold process soap making typically yields a long-lasting bar of soap.
