This water-based personal lubricant is Sliquid’s original formula and the base formula for all of the water-based lubricants in the Naturals line. Formulated to emulate your body’s own natural lubrication, it uses plant cellulose as a thickening agent, instead of glycerin or other sugar derivatives. H2O is not flavored or scented, and is non-staining and extremely easy to clean up. 2 fl. oz.
