Escuir Spray by ESC Laboratoire is made from a very high quality soap made using an old-fashioned manufacturing process. This soap factory located in the heart of Provence applies a method traditionally used for making Marseille soap. Glycerin, which is a natural reaction to the saponification process (mixture of vegetable oils and potash), provides hydration and acts as a nourishing agent. Our soap contains at least 24% glycerin. What to combine Escuir with? In order to maintain and preserve the quality of your leathers, we advise you to regularly use a nourishing balm on your leathers. ESC Laboratoire Leather Balm, made with beeswax and sweet almond oil, deeply nourishes and softens. If you prefer to use glycerin soap in solid form, find Solid Glycerin Soap.
