Abstract: A method for producing water soluble menthol compound produces a menthol compound that is soluble in alcohol and ether, yet insoluble in water. The menthol compound provides antibacterial, anti-inflammatory, and bacteriostatic effects when combined with other compounds to produce numerous medical and consumable compositions, including, without limitation, eye drops, mouth wash, juices, and noodles. In some embodiments, the produced menthol compound is a menthol water-soluble sodium salt or sylvite. However in other embodiments, the menthol compound may include a menthol crystal configuration. The steps include: adding a metal to a menthol solution. Enabling the reaction; dissolving the solid mixture; applying osmosis membrane dialysis to the dissolved solid mixture; filtering, drying, and washing the solid mixture; decompressing and removing water from the solid mixture; and collecting the water soluble menthol compound.
