Glycerinated Soap by ESC Laboratoire is made from a very high quality soap manufactured by a laboratory located in the heart of Provence. Glycerin, which is a natural reaction to the saponification process (mixture of vegetable oils and potash), provides hydration and acts as a nourishing agent. The soap is natural, does not contain silicone, chemical additives or coloring. The glycerin level is 24% minimum. This very practical glycerin soap is packaged in a resealable plastic box.
