​A detergent free soap made with Goats Milk and Shea Butter which are well known as moisturizing agents.  Detergents (SLS or Sodium Laureth Sulfate for example) are chemical foaming agents used in many over the counter products sold as soap, but really are not. True soaps are made from oils in reaction (saponification) to an alkali. A major component of saponification is glycerin.  Detergent based cleansers add glycerin back into their products to reduce potential drying to the skin, but glycerin is an expensive additive and is typically only found in small quantities in commercial products.
