My go-to blend for making long-lasting, skin-loving soap includes olive oil, coconut oil, shea butter, and cocoa butter. This combination creates a firm, luxurious bar that’s both gentle and nourishing. The beauty of soapmaking, however, is that you can customize your recipe with the oils and fats you love most to suit your needs, budget, and preferences.
